Do-it-yourself toilet installation: installation video, step-by-step instructions

If your plumbing has failed, your toilet often needs to be replaced. There are many nuances to this process. It is important to choose the right plumbing equipment. And you should also know how to install a toilet with your own hands. You can watch a video of this process on the website. To carry out such work, you can contact plumbers, or you can try to do the installation yourself.

Self-installation of plumbing will save significant financial resources.

Related materials

In addition to a set of tools, before changing the toilet with your own hands, you need to purchase building materials for installation, including:

• pipe for connecting to the water supply system;
• sealant;
• corrugated pipe for connection to the sewer riser;
• tap;
• FUM tape;
• fasteners.

When exchanging a toilet - an old product for a new one - the main point is to ensure a reliable seal. Any loose connection or gap may result in a leak. When connecting a plumbing fixture to a sewer system, the best solution is to use silicone sealant in a cylinder.

Before replacing a toilet in an apartment or house, you should purchase plastic corrugated pipe products to connect it to the pipeline that discharges wastewater. This product is convenient because it is flexible and suitable in most cases. When bending, the corrugation can take different positions, compressing and stretching. It is suitable for both horizontal outlet and angled outlet.

To seal the joints, use sealing tape or do it the old fashioned way, using tow. The set of fastening elements includes screws, bolts, dowels, nuts, washers, plugs for connecting all components and carrying out installation work. If any fasteners are missing, they can be purchased additionally.

Preparatory work for installation

Regardless of what will cover the floor (tiles or regular screed), you need to wait time for the mixture to dry on the floor surface. This will take about a week. This is due to the fact that the toilet is fixed using fasteners and dowels, which require a reliable and solid base. In this situation, the hardened solution will act as a similar base.

Next, you should prepare those participating in the communication installation process. The area where the drain will be connected must be cleared of various contaminants and salt deposits in advance. Otherwise, it will not be possible to connect the toilet to the sewer riser as needed. That is, the corner or corrugation in the outlet cup will not fit tightly, and a leak will definitely appear.

A tap should also be installed at the connection point of the drain tank so that it is possible to carry out repair and cleaning work without completely turning off the water.

Dismantling

Unscrew the mounting bolts

Disassembly diagram
With the old Soviet fastening method, you must first remove the bolts. They can be unscrewed or simply broken. Most often, they are no longer susceptible to the influence of the tool, so it is easier to break off the heads. Then you will have to break out the toilet itself. It is very firmly mounted into the sewer pipe, because in those days they made it to last for centuries. Having completed dismantling, you need to clear the work area for installation of a new unit. If the model is relatively new, then you won’t have to break anything. You need to unscrew the bolts, which most likely are not too rusty yet. Next, you need to disconnect the plastic pipe from the sewer system.

The need to replace the toilet

It is not always necessary to change a plumbing fixture if there are malfunctions in the sewer system. If water is constantly leaking from the tank in the bathroom, this is a serious reason to think about it.

When it drips onto the floor, and all the pipe connections are in order, then the cause of the problem is usually a chip or crack. In this situation, it is possible to eliminate the leak only temporarily; the toilet should be replaced as quickly as possible.

If water from the drain tank flows into the sewer along the wall of the bowl, then, most likely, the installation of new plumbing fixtures will not be necessary, since the cause of such a malfunction is most likely a leaky valve. Since all internal elements for flush tanks are sold separately, they only need to be replaced with new products.

Plumbing faience and porcelain are rather fragile materials that are characterized by instability to sudden temperature changes. The enamel can become covered with a network of cracks, spoiling the external aesthetic component of the device and threatening complete destruction of the bowl. If this product develops chips or other problems, the toilet should be replaced as soon as possible.

None of the toilet users can know for sure when the ceramic coating on it will not withstand and will burst under the influence of water currents, the weight of a person or as a result of internal stress. It’s good if the residents are nearby at this moment and one of them can quickly eliminate the emergency situation, otherwise the toilet of the neighbors living on the floor below will need to be repaired.

Another sign of a plumbing problem is the presence of an unpleasant odor. Most often, it is caused by improper installation of the sewer system, as a result of which the drainage stagnates in the pipes. When everything turned out to be in order with the pipeline, and the earthenware is clean, the cause of the smell should be sought in the fact that the glossy coating has begun to deteriorate.

If the integrity of the enamel is damaged and the porous structure of the sanitaryware begins to come into contact with impurities, it begins to absorb unpleasant “odors.” It will not be possible to cope with these odors, since the destruction process is irreversible. In this case, it is impossible to do without replacing the old toilet with a new one.

Another important reason for dismantling old and installing new plumbing is the planned renovation of the bathroom. Few property owners decide to keep the same fixture when changing the design of their bathroom.

Since new, more modern products appear on sale regularly, updating a bathroom with replacing plumbing fixtures can transform its interior beyond recognition. Regardless of whether you choose a classic option or an unusual model from the catalog, the process of how to properly change a toilet occurs in the same sequence.

Most common mistakes

Before changing the toilet in an apartment or house, you need to carefully study the instructions of the manufacturers of these products. It is almost impossible to avoid mistakes when dismantling and installing plumbing fixtures in the absence of relevant experience.

There are several types of plumbing work, during which novice craftsmen perform incorrect actions. Knowing them will help you avoid unpleasant surprises during installation activities.

To prevent liquid from stagnating in the sewer pipes, it is necessary to maintain a slope when installing the drainage system. According to building codes and regulations, it should be from 3 to 5 percent in the direction of the sewer riser. If the question is being considered not only of how to change the toilet, but also of moving it to another place, this should not be forgotten.

Some property owners rush to replace the toilet at the very beginning of the bathroom renovation. Experts advise avoiding such actions if possible. The fact is that earthenware plumbing is fragile and during further construction work in the room there is a high probability that it will be damaged. Therefore, it is advisable to change the toilet with your own hands as a last resort.

If a bidet is already installed in the bathroom, the hanging bowl should be positioned flush with its top edge. Only in this case the plumbing fixtures look harmonious in the interior of the room and are convenient to use.

When replacing sewer pipes, inspections must be installed. Access to hatches should always be free - you can use aesthetic doors to cover them. This requirement should not be neglected, since in the event of an emergency you will have to use audits.

Replacing an old toilet with a new one without the help of a professional is quite risky, especially if you have no experience. When installing plumbing yourself, the main thing is to take your time and follow the instructions.

Choice

Installation

Children's toilet
Most often, people do not consider choosing this device a difficult matter. The list of requirements for it is limited to convenience, lightness and, sometimes, color. Most buyers don't go further than this. But in addition to external characteristics, each model has its own technical indicators. Leading companies in the plumbing market regularly update their product range, releasing more and more interesting new products. Focusing only on the appearance and convenience of the toilet, you may soon encounter problems that will not be easy to solve. Before you make a replacement, you need to think about some characteristics.

When choosing a device, you need to take into account the size of the bathroom or toilet. For large spacious rooms, it is recommended to purchase designs with a bidet and a tank. If the size of the bathroom is very small, then you can organically fit a toilet without a tank into the space. Such models have a special built-in flushing system. They are very convenient and will save space in the room. The material used to make the unit is very important. By purchasing cheap products, the consumer runs the risk of receiving low-quality ceramics, which will very soon ruin all the pleasure of the purchase. Of all the offers for the home, it is better to choose models made of porcelain and earthenware in the middle price segment. The internal shape of the bowl is of great importance. Some of the models have a special surface that protects against splashing. The design of the flushing device is also important. It is selected taking into account the features of the communication system in the house. There are three types of such structures: vertical, oblique and horizontal. To make the right choice, you need to look at the features of the flush device in your system. Today there are many models of cisterns. It is necessary to take into account the noise level of the tank, its capacity and other indicators. You should also pay attention to the location of the tank relative to the toilet itself.

Without a tank
It is known that the simplest models are easiest to install. Usually they also do not cause any particular problems during operation. By choosing a design that is too complex, the consumer may later regret his choice. In the simplest models, most problems are associated with the drain tank, which is not difficult to repair.

Instructions for connecting a toilet with corrugation

The basic steps for connecting a toilet to a sewer will be discussed using the common option using a corrugated pipe. Installation of corrugation is the basic and most common type of connection between a toilet and a sewer system.

When deciding to choose a corrugated pipe, you need to be aware of the positive and negative features of this design. The remaining installation options follow the same scheme, but with some differences.

The positive properties of corrugation include:

1. Low cost.
2. Ability to lengthen and bend.
3. No problems with hole alignment.
4. Can be used as a temporary connection.

Among the disadvantages of corrugated pipes are the following:

1. The walls are easily damaged during installation.
2. Periodic cleaning is required on low slopes.
3. Sagging during long-term use.
4. Difficulty in cleaning the external surface from dust.

The final decision on the installation of corrugation is made after taking into account all the above-described features.

Corrugated connections are installed on toilets with oblique and horizontal flushes. Before purchasing a product, you must measure the approximate distance between the toilet and the sewer hole. The length of the corrugation must be at least 1/3 longer than this value.

Step one: fitting

At the beginning of the procedure for connecting the toilet to the sewer, it is necessary to try out the compatibility of the design. To do this, take a rubber seal and insert it into the sewer hole, having previously lubricated the joint with a thick layer of silicone. Then push the rubber tip of the corrugation into the sewer drain.

It is necessary to insert the tip of the corrugation into the seal until the last rubber ring is level with the cast iron pipe

After inserting the corrugated pipe, at subsequent stages of installation, it is not advisable to twist it until the silicone has completely dried.

The next step is to take the toilet and install it in its planned permanent place. Sit on it, checking that it is stable and does not rock. If the toilet is unstable, you will need to level the floor or install expansion stands to correct the unevenness of the tiles.

If the toilet is stable, then it is necessary to connect a corrugated pipe to its pipe without lubricating it with silicone. After this, you need to pour three buckets of water into the toilet and, after waiting a minute, check both holes of the corrugation for leaks.

Horizontal toilet pipes may leak a few drops at the junction with the corrugation. The leak is subsequently repaired using sealant

If there are leaks, it is necessary to remove the corrugation, check the correct location of the rubber seals and once again connect the parts along their axes.

If there are no leaks, then you need to mark with a marker where the toilet is attached to the floor.

Before determining the location for the toilet, it is recommended to let all residents sit on it to determine the optimal location of the equipment

After the measurements, it is necessary to disconnect the corrugation from the toilet and secure it so that there is no distortion at the junction with the sewer hole. Move the toilet aside.

Step two: fixing the toilet

In the designated places, we drill holes in the floor with a drill, insert dowels into them and place the toilet in a permanent place.

It is recommended to make holes in the tiles using a special spear-shaped drill, which reduces the likelihood of chipping and speeds up the drilling process

After installing the toilet, we fix it to the floor. Then you need to sit on the toilet and move your center of gravity in different directions for a minute. After this, tighten the fixing screws again and put decorative caps on them.

Before installation, most installers advise treating the joint between the toilet and the tiles with waterproof silicone. But they do not take into account the complexity of subsequent cleaning of the premises. After a few months of cleaning the floor, the silicone sealant will peel off from the joint and a gap will form.

Therefore, before installing the toilet in place, you need to turn it over and lubricate the perimeter that will come into contact with the tiles with silicone. After this, you should put the toilet and screw it on, and seal the gap between it and the floor with a sealant on a waterproof cement base, which will not be destroyed when the bathroom is wet cleaned.

The features of installing a toilet on a wooden floor are described in this article.

Step three: sewer connection

After installing the toilet, you need to lubricate the inner surface of the rubber corrugation with silicone and pull it onto the toilet pipe.

It is necessary to stretch the corrugation evenly along its entire length so that the slope is maximum and there is no sagging anywhere

After installing the corrugation, you must wait 2 hours until the silicone hardens and only then proceed to the next step.

Step Four: Testing

After the sealant has dried, you can test the toilet by sitting on it and performing 2-3 full flushes. If after 5 minutes nothing has leaked, then you can screw on the tank with the toilet seat and use the plumbing.

In case of a small drop-shaped leak, you should completely remove the water from the toilet bowl and remove the corrugation from it. After this, re-lubricate the rubber band of the corrugated pipe with silicone and pull it onto the toilet pipe. You can also additionally lubricate the joint with sealant from the outside.

At this point, connecting the toilet to the sewer using a corrugated pipe can be considered complete.

Preparatory work

Of course, you remember that if you have ceramic tiles on the floor, then the floor must be level. If you neglect this detail, the toilet may split or crack. But if you don’t have tiles, then be sure to make an even screed. After completing the work, leave the floor to dry for at least three days. This is due to the fact that the toilet will be mounted using toilet dowels, and in order to securely fasten them, you will need a reliable base. So it’s better to take your time than to redo it later.

Since you are replacing the toilet yourself, you can now proceed to preparing communications:

Replacing the tank

toilet cistern installation

Replacing the toilet tank yourself is the last stage of the work associated with replacing the toilet. If we are talking about a barrel that is attached to the toilet shelf, then the pipe must be connected to the neck using a rubber cuff. This will be quite enough to ensure a strong and tight connection. One third of the rubber cuff is put on the pipe, and the remaining two thirds are turned inside out. Then this part must be pulled over the previous one. Here we get a situation where the end of the pipe is released. Then the pipe and neck are combined with each other. The inverted part of the rubber cuff is pulled over the neck. Thus, we can say that the tank is perfectly secured. No additional action is required. The rubber cuff is enough to ensure a tight connection. At the same time, it is worth checking the tightness of the cuff nozzle so that unpleasant events do not happen to the neighbors below.

attaching the toilet cistern to the toilet itself

Sometimes a situation arises when the tank is mounted a short distance from the toilet on the wall. In this case, a rubber cuff alone is not enough. You'll have to put in a little more effort and skill. In this case, a pipe is screwed to the barrel, and its opposite end is lubricated with red lead and wrapped in tow. The neck of the toilet and the pipe itself are connected by means of a cuff. It is fixed to the pipe using a thin wire. Now you can energize the flush tank and adjust the water level in it.

Thus, the work on replacing the toilet can be considered completed. As you can see, all actions do not require any special training. The work can easily be done with your own hands. Of course, if we are talking about a toilet that is installed on the floor. Otherwise, it is difficult to do without the help of a plumbing specialist. By the way, even before starting work on replacing a floor-standing toilet, you should consult with a professional. He will help you understand all the intricacies of the work. For those who are well versed in the work associated with installing plumbing, this manual will definitely help. It is also suitable for those who have never tried to do such work on their own before. Here you can find detailed instructions describing all the main stages of the work, and also attach a video showing clearly how to replace a toilet with your own hands. Many will definitely find this guide useful. In addition to the work associated with installing the barrel and the toilet itself, it provides information on how to correctly dismantle the old unit so that there are no further problems in operation. The video will help even those who decided to save money and not call specialists, although this is the first time they are dealing with this type of work. Everything is shown clearly and will be understandable to absolutely every person.

Dismantling the toilet

The cement coating from the base of the bowl is knocked off with a hammer and chisel.

Before proceeding with the installation of plumbing, turn off the water supply and dismantle the old unit. To do this, follow this scheme:

1. Drain the remaining liquid from the tank
2. Using a wrench, unscrew the hose connecting the water supply and the tank, and then dismantle the tank itself
3. Disconnect the floor mounts of the device
4. If the drain is secured with cement coating, use a chisel and hammer to crack the concrete around the unit. The bell of the bowl is carefully pulled out of the drain pipe, draining the remaining water into the sewer. Then cut off the seal or wax ring
5. The old device is removed from the room, the sewer hole is cleaned, and temporarily covered with a piece of fiberboard or plastic. While working, the hole can even be covered with a rag.
6. A tap is installed on a water pipe to stop the flow of water.

Rotten supports can often be found under the dismantled device in old houses. They must be removed using a chisel or hammer drill.

The easiest way to dismantle a bowl attached to the base with adhesive mastic is to simply hit the base of the bowl's sole away from you. This method of fastening is considered to be of poor quality and indicates unprofessional installation of an old plumbing fixture.

Dismantling

Let's say it like it is - removing the old toilet with your own hands will not be easy. There are rare occasions when it is not too securely in place and all you need to do is disconnect it from the water and sewer supplies. But if you have an ordinary apartment in, then things are not so smooth, since, as a rule, the toilet is walled up in the floor, and it is not possible to get it out of there. Then you will have to break the toilet with your own hands.

When dismantling the cast iron tee, note that it has one outlet with a diameter of 10 cm for the toilet and 7.5 cm for other sewer pipes. Since you will be replacing the pipes with plastic, you will need a 5 cm bend so that you don’t have to install a reduction in the tee

You can replace such a tee due to its large dimensions - a plastic one will be more compact. It must be removed by carefully loosening it so as not to accidentally damage the intermediate tee standing on the sewer riser.

Toilet replacement process

We make a country toilet for the toilet with our own hands

You can easily make a toilet for a country toilet with your own hands. It is not at all necessary to buy a ready-made ceramic or plastic structure. It is enough to build the toilet itself, and equip a high ledge with a hole inside, which will act as a pedestal. For comfortable use, a seat is placed on the hole.

Pedestal with plastic seat

In rare cases, water supply is also provided to the toilet. The presence of a water seal is necessary for a toilet with a tank. Step-by-step instructions on how to make a toilet for a country house with your own hands:

1. When the hole is dug, reinforced and equipped with a seat, you need to install the toilet on the hole. You can do it yourself in several ways. The simplest one is to connect several boards to create a rectangle, the size of which will be smaller than the hole. The resulting structure is installed on a pedestal using corners and screws. If desired, the top of the board can be covered with textiles. For durability, it is recommended to treat them with an antiseptic;
2. A more comfortable option is to attach a finished seat to the hole. This can be any seat purchased from a hardware store. To install, you will need to drill two holes in the seat to connect the cover and the hole. Using bolts installed in the rear part of the lining, you need to fasten both elements together;

   
   Installing a toilet seat

3. Another option is to build a real toilet seat out of wood. The design can be any: with or without a backrest, armrests, stands. The easiest way to select the dimensions of such a toilet is according to the parameters of a regular chair. It is important that it is ergonomic: high enough, comfortable, stable. You can also install a plastic seat cover on top of the wooden platform as a cover.

Installation of a hanging bowl and a hidden tank

It should be noted that the work on how to change a toilet of a conventional design to a wall-hung product with a hidden drain container yourself differs from the previous option in greater complexity. In this case, it will be necessary not only to replace the plumbing equipment, but also to repair the floor covering, build a false wall with its further finishing with tiles or other modern materials.

You have to attach the hanging bowl to a durable installation. After finishing the walls, the fixed metal frame will not be visible. When carrying out renovations in a combined bathroom, when decorating the interior, it is advisable to install a wall-mounted washbasin and a bidet of a similar design.

A detailed description of how to change a regular toilet to a wall-mounted one is as follows:

1. Mark the location of the plumbing fixture. A sewer pipe with a diameter of 110 millimeters and an inlet is connected to it.
2. Try on the purchased installation, which is a rigid frame for installation. You need to decide on the height. The standard placement is 450 millimeters from the floor to the seat and 100 millimeters from the floor covering to the bottom edge of the seat.
3. Using a marker, mark the places of fixation to the floor and wall of the bathroom so that they exactly coincide with the mounting holes.
4. They are prepared using a hammer drill and the frame is installed. Using a level, check the correctness of the installation work.
5. Water is connected to the drain tank.
6. The installation kit includes a diagram for cutting plasterboard sheets to cover the installation site. GCR is attached to the metal profile and to the installation. It is better if they are moisture resistant.
7. Finishing is carried out taking into account the personal preferences of residents.
8. When replacing a toilet bowl, it is connected to a corrugated sewer pipe and a drainage system, not forgetting the need for sealing.
9. The bowl is screwed directly to the installation frame through drywall and tile using pins.
10. The device is connected to the sewer system and the drain tank.

Despite the fact that the process of replacing an old toilet with a wall-mounted product takes a lot of time, the result of such a repair looks stylish and expensive. The work of installing an electronic plumbing fixture with the addition of automatic hygiene functions has much in common with fastening and connecting a conventional product, but there are still some nuances.

The fact is that to connect a smart wall-hung toilet, you need to provide it with power. For this purpose, a separate line is usually laid, since smart equipment is sensitive to voltage drops in the network.

Connecting a toilet with an oblique outlet

The socket in such toilets is placed at a 45-degree angle relative to the floor. Such models of plumbing equipment are superior to their counterparts in that they do not clog so quickly. The fact is that solid waste moves with less resistance.

A toilet with an oblique outlet in a house or apartment is connected to the sewer system in different ways:

• Direct connection using a socket extending from the riser. This option is suitable when the toilet does not need to be moved anywhere, and the direction of the elements coincides. The outlet from the bowl is treated with a soap solution for easier penetration into the socket with a cuff.
• Connection using an eccentric. The bell has a center offset by 50 mm with a seal. It is connected to the sewer outlet, and the toilet is moved to the right or left.
• Using corrugation is another way that allows you to rotate the toilet bowl relative to the sewer hole in any direction.

The last type of connection for floor-standing toilets is the most unsuccessful of all, since the corrugation gradually becomes clogged and requires cleaning. This method should be used in private houses or apartments when other options are not available for one reason or another.

Preparation process

Types of pipe supply from the tank to the plumbing

When choosing a toilet, it is important to consider the type of connection of the tank to the water supply system. There are side and bottom inlets

With the lateral type of supply, the tank is connected from the side; this option is more popular.

In the lower type of supply, the tank is connected from below; this option is considered quiet and allows the pipes to be hidden from view. The sideways type is gradually pushing out of the markets.

It is necessary to purchase a suitable type of supply for the existing sewer structure if there are no plans for a major replacement of water supply pipes.

Tools you will need when replacing a toilet structure

To replace a broken toilet, you will need standard tools. The composition of the kit varies depending on the characteristics of the out-of-service plumbing, the type of toilet, the condition and location of the pipes.

You will need a hammer drill, a screwdriver and an adjustable wrench, a chisel with a hammer, a hacksaw, a rubber spatula, a measuring level, safety glasses and work gloves.

An adjustable wrench is used when connecting a water supply. A hammer drill is used to make holes in a concrete wall or floor for attaching a tank or bowl. Screwdrivers are needed to tighten screws. Silicone sealant is used to process joints.

What items to prepare in advance

To quickly dismantle and install new plumbing fixtures, you need to buy the necessary items in advance, namely a compact toilet. The composition includes rubber sealing rings, fasteners, and a tank drain device. If there is a cast iron riser installed under the toilet, you will need a chisel and hammer. When installing the bowl for accuracy, use a measuring level.

Consumables you will need when replacing plumbing fixtures

If there is a shortage of bolts, screws, washers, or dowels in the mounting kit, you can independently purchase the missing ones.

The process of dismantling an old toilet

Dismantling modern equipment will not cause many difficulties. The process of dismantling outdated plumbing has its own nuances if the sewer system consists of a cast iron pipe.

If the toilet is attached to a wooden stand, it is quite easy to remove. The stand itself is removed and the floor hole is filled with a special screed.

A step-by-step description of the dismantling of modern toilets

First of all, we limit access to water, then drain the water from the tank. We remove the remaining water using a bucket and a rag. At the bottom of the tank, unscrew the bolts and remove it, take out the corrugated pipe or plastic eccentric connecting the sewer and the bowl. It is necessary to wipe the bowl dry with a cloth or sponge. Use a wrench to unscrew the fastenings under the bowl, and it can be freely removed from the floor.

Removing a toilet installed with cement mortar

In Soviet times, the installation of plumbing was done conscientiously; the toilet was installed using cement mortar. Dismantling the plumbing will be similar as for modern toilets until the bowl is removed. Using a chisel, hammer the base of the toilet in a circle and crack the cement, then rock the toilet, use the chisel to carefully split the outlet and remove the bowl. Then remove the remaining plumbing fixtures and cement mortar from the pipe.

Features of connecting to the sewer

After this, the installed toilet requires connection to the waste disposal system. In fact, there are two types of entrance to the sewer outlet - horizontal (relevant for new buildings) and vertical (typical for old buildings). For them, plumbing fixtures with the appropriate outlet are selected - horizontal or vertical. Devices with oblique outlets are considered universal and can be connected to any type of sewer system.

Typically, the type of toilet is selected to match the existing drainage system in the building. In the case of laying sewerage “from scratch”, they are guided by their own preferences.

It is important to maintain the required distances and differences between the plumbing fixtures and the riser. The use of an eccentric helps with this, and the simplest and most universal method is the use of corrugation.

When making connections, it is important to apply plumbing sealant along the edges of the cuff to enhance the sealing effect and at the same time lubricate it in order to facilitate installation, but not much, because its excess will lead to a decrease in the reliability of the connection.

Vertical outlet bathroom

The most common drainage option in European countries due to the versatility of the design, which allows the installation of the bathroom to the wall at the desired angle. The device consists of a siphon in a bowl and an outlet pipe directed downwards.

Installation is quite simple:

• floor markings are carried out and a conventional screw flange with a lock is installed;
• a sewer hole is installed in the center of the flange;
• The toilet is mounted on a flange with reliable fixation of the outlet pipe.

Horizontal outlet toilet

Received maximum distribution in Russia. Another name for this option is “direct outlet into the wall.” The drainage of the device is directed backwards. The connection of the branch pipe to the sewer pipe is made using a specific cuff.

This type of toilet is fixed directly to the floor through special holes in the base of the device.

Recommendation! It is better to begin work on connecting direct outlet plumbing during installation. Fastening is done using dowels and standard screws.

The nuances of choosing a new plumbing fixture

Before carrying out renovations in the bathroom, you should carefully prepare for it. You especially need to think about how to change the toilet in an apartment with your own hands when the residents continue to use the toilet.

In this case, the plumbing fixtures should be changed as quickly as possible, but without proper organization of repair work this becomes impossible. First of all, they select a suitable model, prepare all the tools and building materials, and then begin to implement their plans.

The most important thing before installing and dismantling the toilet is to purchase a new plumbing fixture. Depending on the selected model, a set of tools and materials is prepared to perform the replacement.

There are two types of toilets:

• floor;
• hanging.

Floor-standing models are more popular and their choice is huge. They come in “compact” and “monoblock” types, with separate tank and bowl, as well as with a hidden drain system.

A monoblock is a product that combines a water tank and a bowl into a single system. In a compact toilet, these two parts are sold as a set and are connected during installation - this is the most popular option presented on the domestic market of plumbing products.

Retro models, during installation of which the tank must be placed under the ceiling and connected to the bowl with a pipeline, have become increasingly rare in recent years. In them, to flush, you need to pull a string or chain with a handle. Such plumbing fixtures look appropriate in a bathroom decorated in the appropriate style.

A modern solution is to install a hidden drain system. Before replacing an old toilet with a new one of this type, it is necessary to consider the construction of a false wall, behind which the flush tank with the installation system will be hidden. Externally, hidden models look very neat, since only the drain button will be located on the wall, and utility lines will remain hidden.

The bowl of a wall-hung toilet is not placed on the floor. It is hung on anchor bolts mounted into the wall. As a result, there is free space under the bowl and it can be used to advantage. This design is also advantageous from a hygienic point of view. It is not difficult to wash the floor underneath, but dirty residue often collects around the floor product.

Another important point that should be taken into account before replacing the toilet with your own hands is the direction of release from the bowl, which comes in three types:

• at an angle;
• straight;
• vertical.

As for devices with a vertical drain, they are usually used in homes in America and China. Its convenience lies in the fact that the toilet can be placed anywhere in the bathroom, and communications are laid in the interfloor ceiling. This arrangement option can also be implemented in domestic sewer systems, but only in private households.

Design and principle of operation

To ensure the normal operation of a country toilet, it is not enough to dig a cesspool and install a platform on it. When operating such a makeshift structure, odors will spread throughout the area, not to mention the likelihood of the walls of the pit collapsing.

Classic outdoor toilet design

To avoid these troubles, the walls of the cesspool are strengthened with bricks or cinder blocks, and peat is poured into the hole itself. The peat layer not only helps eliminate the smell of feces, but also makes it easier to process waste into useful fertilizers.

The design of a toilet for an outdoor toilet is a combination of two separate parts of the structure:

• The top one is a seat or pedestal (depending on the chosen design). From here, waste products fall into the pit. Can be connected to a septic tank;
• Lower. Here the peat layer is located and waste is processed. It is important that the cesspool is closed, otherwise some of the waste will fall into the ground and poison the groundwater.

The height and depth of both parts of the toilet can be any depending on your needs. But the recommended parameters: the toilet seat should be at least 40 centimeters, and the hole should be less than 1 meter.

Instructions for replacing a toilet

wall hung toilet in the bathroom

Now the main problem remains to be solved, namely, installing a new toilet. The toilet installation option depends on many factors. The most important thing is the type of fastening and the type of toilet itself. A wall-hung toilet for a small bathroom is often installed by specialists, since its design is quite complex. If we are talking about installing a floor-mounted option, then you can use traditional installation methods. So, you can get to work.

Replacing a toilet can be done by installing it on a tile or concrete floor. This is the traditional method. In this case, self-tapping dowels serve as fasteners. the second option is to attach the toilet to a wooden board or taffeta. The best wood for this installation method is oak.

fixing the toilet to the floor using dowels

In this case, anchors are installed at the bottom of the board. They provide a fairly strong attachment to the floor. Nails that are driven in in a checkerboard pattern can be used as anchors. At the same time, they should protrude from the board by 30 centimeters. A recess is made in the floor, which is filled with cement mortar. Taffeta is placed in it. After the solution has hardened a little, you can screw the toilet using ordinary screws.

Regardless of the method used to secure the toilet, it is worth placing rubber washers under it to protect the base from damage. There are cases when fastening is done not with screws, but with epoxy glue. For proper connection, the surfaces must be thoroughly cleaned and then degreased. Only after this can you connect them to each other. It is worth pressing the toilet tightly to the floor to ensure a reliable and durable connection. The toilet cannot be used immediately. First, you need to soak it for 10-12 hours so that the solution or glue can harden.

You should also pay special attention when connecting the toilet to the drain line. The part of the toilet that connects to the sewer is called the outlet

Moreover, it can be straight or oblique. Any outlet has grooves that must be coated with red lead diluted in drying oil. The release itself must be wrapped with a resin strand. At the same time, you should ensure that it does not reach the pipe by 2-4 millimeters. If this rule is not followed, resin strands may get into the pipes and clog them.

The outlet itself must then be inserted into the socket. In this case, the annular gap is caulked using flagella made from linen yarn. After this, the gap must be sealed with cement mortar.

How to assemble and install plumbing fixtures

A floor-standing toilet can be installed and secured in several ways:

• on a pre-filled screed;

• on a wooden base;

• on the tile.

You should first install new plumbing fixtures in the future location and make marks with a marker at the points of future attachment to the floor. If you intend to use a wooden platform, then you need to cut the workpiece in advance and place it on the floor. For ease of marking on tiles, use paper tape - the dots will be better visible on it.

It can be secured using dowels or anchor bolts. In both cases you will have to drill holes in the floor. Some toilet models require the use of ready-made platforms with bolts. The base is attached to the floor, and plumbing is placed on top. This greatly facilitates installation and gives the bowl stability.

It’s easier to attach a small platform than all the plumbing at once

The easiest way is to install using dowels.

1. First you will have to drill holes and carefully hammer plastic caps into them.

2. Then you need to install the toilet on the platform and tighten the screws. It is important not to overtighten the fasteners so as not to break the body or dowel.

   
   Assembly is complete When installing the main part (bowl), it is necessary to connect the drain neck with the previously secured adapter pipe. To seal, it is important to coat one side with sealant.

   The use of a corrugated pipe will allow you to connect the drain to the waste pipe later.

3. Assembly and installation of the drain tank, as well as its connection. The fittings located in the container must be assembled according to the instructions and installed inside.

Features of installing a floor-standing toilet of the “compact” type

Pipes in the toilet are often covered with a plasterboard box.
Such devices are considered standard and consist of a bowl and a tank attached to it. During installation, you should pay attention to the preparation of the site, since the base of the toilet should sit firmly on a flat surface. Since the pipe connected to the sewer pipe will remain visible after installation, you can close it by making a box from plasterboard. Tiles are often laid on top of the casing.

Metal profiles are used as a frame.

Features of installing a floor-standing toilet with a monoblock

Each type of plumbing fixture has its own installation features.
Monolithic construction is considered more reliable, since the bowl and tank are combined. However, the heavy weight forces the platform to be further strengthened.

Installation on concrete that has not yet completely hardened is not allowed.

The base should also be securely attached to a horizontal plane to avoid breakage.

Features of installing a floor-standing toilet with a high cistern mounted on the wall

The container is connected to the bowl by a long pipe.

To properly install such a toilet, you need to carefully check the planes and angles at the installation site. Distortions can lead to poor-quality connection of elements and cause leaks. The base of the bowl should fit snugly to the floor without being able to move.

Installation of a wall hung toilet

Such a frame is needed so as not to damage the walls.
The peculiarity of such plumbing is the need to strengthen the wall at the attachment point. Otherwise, the toilet may damage the panels. It is recommended to make a special frame from a metal profile and attach the bowl to it.

After installation, the frame must be covered with plasterboard panels and tiles laid.

Carrying out work to dismantle the old toilet

To change a toilet with your own hands, first dismantle it. If the device is not too old, there are usually no problems with this process. When the model of plumbing and cast iron sewer pipes are still Soviet-style, in this case you will have to work hard.

If the device is not in very bad condition, the dismantling process will not be too laborious:

1. First, before draining the toilet when replacing it, turn off the water pipe.
2. Prepare containers for collecting water and rags.
3. Disconnect the tank by unscrewing the bolts from below.
4. Remove the plastic eccentric or corrugation connecting the bowl outlet and the sewer system.
5. Using a regular sponge, remove any remaining water in the container.
6. Using a wrench, unscrew the fasteners located on the sides of the base; there are usually 2 or 4 of them.
7. Use a knife to remove the silicone sealant from under the base.
8. The bowl is removed from the tile.

In the past century, all installation work was done in such a way that the plumbing would last for decades. Until now, when replacing a toilet in a Khrushchev-era building, you can find the device mounted on cement mortar and embedded in a screed with rags wrapped around the base and finally covered with several layers of paint. In this case, its connection with the sewer pipe is covered with a thick layer of solution.

Now this installation method looks ridiculous, but until the home craftsman has to dismantle the rare device. In cases where ceramics are not a concern, the toilet bowl can be dismantled in parts. To do this you will need a hammer and chisel.

You must first knock at the junction of the bowl and pipe, while simultaneously rocking the mount. If the structure does not give in, you should hit the neck of the plumbing fixture and it will crack. After this you can remove it. The main thing is not to hit the cast iron pipe with a hammer, since it is fragile and will crack easily.

Tips for installing a toilet

1. If during the renovation of the bathroom the floor height has changed slightly, it is necessary to compensate for the difference using an eccentric cuff - the so-called toilet corrugation (for sewerage) and a flexible hose (for supplying cold water). Large changes in height will require the skills of a professional plumber.

2. If the floor in the bathroom is not level enough, it is better to install the toilet with silicone sealant. You can also use small wooden / plastic wedges, but even here you can’t do without sealant, since it allows you to evenly distribute the weight of the toilet.

3. If the sewer pipes go down through the floor and not through the walls, you will need a rectangular elbow or a flexible corrugated cuff. This is not the only difference, but the main one.

Installation

Work on fixing and installing the toilet proceeds as follows:

That's all the subtleties of replacing a toilet. In conclusion, I would like to note the following: if you find out another way to change a toilet with your own hands, this does not mean that it is wrong. There are simply always several methods for solving a particular issue.

Replacing a toilet is required when the old product becomes unusable. More often, dismantling an old toilet and installing a new one is in demand in older buildings, where all communications need to be updated. Replacing the toilet tank and other parts yourself is not difficult. However, it requires basic skills in working with tools (a hammer drill, a drill, etc.) and the ability to fill and lay tiles. Read how to install a toilet in a private house with your own hands and watch the video tutorial below.

Installation procedure for different types of products

Compact

Do-it-yourself installation of a floor-mounted compact toilet is done using the following technology:

1. The toilet needs to be moved as close to the drain hole as possible and connected to the sewer pipe with a corrugated pipe.
2. To make it easier to put the pipe on the outlet, it needs to be lubricated inside with liquid soap. The second end is simply inserted into the sewer pipe.
3. The toilet needs to be moved closer to the wall, but so that creases or strong bends do not form on the corrugation.
4. When the position is adjusted, the locations for the dowel holes are marked on the floor.
5. For ease of operation, the toilet should be moved aside and holes of the appropriate diameter should be drilled in the floor.
6. Plastic plugs are inserted into the holes, the toilet is moved to the selected location , and the bolts are screwed into the prepared holes.

Since a perfectly flat surface of the sole is a fairly rare phenomenon, it is advisable to apply a layer of white silicone to the sole. In order not to overturn the toilet, silicone can be applied to the floor, and the device itself can not be moved, but raised and placed.

Monoblock

The monoblock toilet is a single unit and is supplied fully assembled. When installing a monoblock product, no assembly or adjustment of the drain mechanism is required ; all fittings are adjusted by the manufacturer.

Otherwise, the task of installing a monoblock toilet is technically no different from installing compact models. The device is mounted and connected to communications in the same way .

With a high tank

The flush cistern is installed after connecting the toilet to the sewer. A drain pipe is connected to it , and a drain pipe is attached to the tank in the same way.

Then, taking into account the height of the pipe, you need to mark on the wall the locations of the tank mounts and drill holes in the designated locations. The tank is disconnected from the pipe, mounted on the wall and a drain pipe is installed.

Installation process of a compact toilet: how to replace it yourself

In order to replace an old device with a floor-standing product of the “compact” type when installed on a tiled floor, you need to use a step-by-step description of how to replace a toilet yourself:

1. First of all, determine the location of the new device. The bowl is placed in the bathroom without fastening. You need to try to sit on it. It is advisable to try on several options.
2. Once the exact location is known, the base of the bowl is outlined with a washable marker. It is also used to mark the places where plumbing fixtures will be attached.
3. The product is put aside, and after that all the necessary marks remain on the floor. Then, using a drill with a 12-bit drill bit, holes are drilled in the tiles. If the surface is concrete, then it is better to beat it with a drill number 12. Dowels are inserted into the prepared holes.
4. Then they take a corrugation or cuff to connect the outlet of the device to the sewer system. The connecting element is placed in place, having previously treated the joint with sealant.
5. The new bowl with corrugation is installed correctly. Bolts are threaded through the mounting lugs and screwed in using an adjustable wrench. The main thing is not to overdo it when performing this work and not to damage the ceramics.
6. The device is connected to the sewer pipe, treating all joints with silicone.
7. A tank is installed on the bowl.
8. The elements are connected with bolts and the container is connected to the water pipe.

Finally, all joints and threaded connections are checked for leaks. If no deficiencies or deficiencies are found, you can use new plumbing equipment.

The process of how to change a toilet of this model yourself is simple, since modern products are designed in such a way that when they are replaced, the floor covering remains intact.

Do-it-yourself toilet installation: basic nuances and recommendations

The process of installing a toilet with your own hands can be divided into several stages:

• selection of new equipment;
• dismantling the old;
• repair, if necessary, the sewerage system or replace individual elements. In addition, it may be necessary to replace the facing tiles;
• installation of a new toilet, connecting the tank to the water supply.

Let's look at the entire installation process step by step.

What tools are needed to install the toilet?

Before work you will need the following tools:

• perforator;
• yardstick;
• adjustable wrench and wrench;
• flexible water hose;
• tape-fum;
• fasteners;
• silicone sanitary sealant.

To install the installation system, you will need additional tools and fasteners. The entire set can be easily purchased at any retail outlet that sells plumbing equipment.

Removing an old toilet

Replacing a toilet with your own hands can hide some difficulties. Let's look at the whole process step by step with recommendations for overcoming possible difficulties:

1. Before starting work, it is necessary to shut off the water supply to the tank.
2. Drain the water from the tank and make sure that its supply is stopped.
3. Disconnect the drain hose.
4. Unscrew the fastenings of the tank to the toilet.
5. Unscrew the toilet fastenings to the floor.
6. Disconnect the bowl from the drain hole in the sewer pipe. If the equipment was installed a long time ago and the drain is coated with cement, use a hammer and screwdriver to destroy the cement mortar. Before you disconnect the toilet, you must drain the water from the elbow. To do this, you need to tilt it several times in different directions.
7. After all the manipulations, the toilet bowl can be removed.
8. The sewer hole must be temporarily closed with a plug or cloth.

Dismantling of old equipment

Preparing a new toilet for installation

Before installing the toilet on a tiled floor, you need to check the surface level. It should not have slopes or drops. If you are replacing the cladding or installing a toilet in a new room, you must first fill the screed level and finish it with tiles. It would also be a good idea to take an inventory of the sewer lines.

How to install a regular toilet with your own hands: a step-by-step guide

After the preparatory work has been completed, you can begin installing new equipment. Please read the instructions carefully beforehand:

Illustration	Description of work
	Assemble and secure the drainage system in the cistern. Before installation, coat the gasket with silicone.
	To install the toilet tank, first install the rubber gasket between them. Before fixing the tank, coat the bolts with silicone and install conical rubber washers.
	Then you need to screw the tube with the float. Securely fix it from below.
	Place the bowl in place. At the same time, you need to insert the corrugation into the sewer hole in order to take measurements and outline the leg of the product along the contour, mark the holes for the anchor bolts. The rubber seal of the corrugation and the toilet flush area can be coated with sealant for reliability.
	Using a drill, drill into the tiles corresponding to the diameter of the dowels included in the kit.
	To drill holes in the screed, you need to replace the drill in the hammer drill with a drill of the same diameter. To control it, you need to mark a strip along the length of the dowel with electrical tape.
	Drive dowels into the holes and install the equipment in place. Then fasten with screws with plastic spacers. When tightening with a wrench, you must be extremely careful, as you can damage the ceramic product. When finished, install plastic plugs on the screws.
	Connect the water supply hose last.
	It is necessary to check several times that the tank is full and that there are no leaks. At this stage, you can use the float to adjust the filling level of the tank for economical water consumption. After all the manipulations, screw the lid to the drain tank.
	To install the seat, you need to install gaskets on the brackets, secure them, insert them into the holes of the toilet and secure them with a special washer from below.

Installing a toilet with a hidden cistern

The arrangement of a sanitary room can be done taking into account modern technologies and maximum comfort. For the most demanding owners, equipment with a hidden drain tank is offered. It fits perfectly into the latest interior solutions. You can choose a floor-standing model or a hanging frame installation. Installation of a toilet installation can be divided into 2 stages: installation of the flush cistern and installation of the toilet.

Modular installation system

Installation of a wall-mounted toilet on an installation

Before installing the installation, it is necessary to make markings on the wall. To do this, use a tape measure and a level to determine the location of the central axis, then measure the perimeter of the installation from it. It is important that the distance from the edge of the tank to the wall is at least 135 mm. You should also mark the equipment attachment points. The level will help you accurately determine horizontal and vertical lines.

Related article: To understand what an installation is and how to choose a wall-hung toilet for it, in this article we will look at the features of different types, selection criteria and several popular manufacturers of this type of equipment.

You should know! Installation of a built-in toilet with installation is only possible on a load-bearing wall.

After marking, you need to use a hammer drill to drill holes for future fastening. Then insert anchors into them and secure the base of the modular structure. After installation, you need to check everything again with a level and level the system with height regulators and plugs.

Next, you can install the tank. Fastening should be done with special connections that were included in the equipment package. After which you can connect the system to the water supply. Using a plastic clamp, attach the sewer outlet and treat all connections with silicone.

To install a toilet with your own hands, you must perform the following steps:

• screw the pins into the pre-drilled holes;
• place couplings on the studs;
• check the pipes for compliance with the dimensions;
• before installing the bowl for shock absorption, you need to install a silicone or rubber gasket;
• install the equipment and inspect all connections for leaks;
• connect and secure the drain hose with clamps.

After installing the structure, it is important that the distance from the edge of the modular system to the wall surface does not exceed 210 mm. Otherwise, after installing the false panel, the length of the bolts will not be enough to secure the toilet.

When is replacement needed?

If various kinds of problems appear with the toilet, this does not mean that it is necessary to change it. There are cases when it is enough to simply repair an element or simply replace it. This can happen for various reasons. So, for example, if there is a leak at the junction of the hose and the toilet, you just need to turn off the water, disconnect the hose and coat it with silicone sealant. This will fix the leak. Or, if the tank does not hold water and it constantly flows, then you need to open the lid and replace the drain system. These simple measures can extend the life of the toilet for a long time without the extra costs of replacing it.

Sometimes it happens that more serious problems arise that cannot be repaired.

In this case, you will have to buy and install a new toilet. The materials from which toilets are made are most often very fragile and cannot withstand shock or temperature changes. If cracks or chips appear on the toilet, this can lead to its destruction. It needs to be replaced as soon as possible.

It happens that an unpleasant odor appears from the toilet. This can be either a smell from the sewer itself, or if dirt has started to get into the cracks. Sanitaryware has a porous structure; microbes enter through chips. The only solution to this problem is replacement. Bathroom renovations can also be a reason to buy new plumbing fixtures. If you plan to carry out major renovations in the apartment, then it is best to buy and install new equipment, and not just replace the floor and walls. You can do this yourself if you carefully study and follow all the instructions.

Before installing a new toilet, you must dismantle the old one

, which most often already has an ugly appearance, is cracked in some places or covered with a thick coating. If the house is old, and the renovation was carried out many years ago, then it is unlikely to be possible to remove the old toilet without breaking it, since its base is firmly concreted into the floor. This method of cementing the floor and attaching the toilet to this place was very popular in Soviet times, when it was customary to do everything with high quality and for a long time.
