How to choose the right grease trap and install it on the sewer

Disconnection of utilities serving a house for non-payment is not such a rare occurrence.

Whether they can block the sewer system for debts or whether this is an illegal measure - the consumer does not know a definite answer, which allows the utility company to choose blocking or another method of punishment at its discretion.

But in order to find out whether it is possible for debtors to block the sewer system, it is worth turning to the laws regulating the housing and communal services sector. As in other matters, documents approved by the Government are considered the main authority for resolving the issue.

ATTENTION! According to Article 153 of the Housing Code of the Russian Federation, residents of houses and apartments connected to utilities must pay for utilities on time and in full. Violation of these duties will result in punishment.

The utility company has the right to turn off the sewerage system or other pipeline for non-paying utility service providers. Another measure is to file a lawsuit against the debtor. But litigation can drag on for a long time; this method is rarely effective; more often, employees of the management company or housing office place a blocker on the pipes of engineering systems.

The water or heating in the apartment cannot be turned off for debts; this poses a threat to the lives of the residents . If housing and communal services employees restrict the use of the water supply or heating system, you need to file a complaint against them, for example, to the prosecutor's office.

Gravity pipe angle

In order for the free-flow sewer system to work in the house without problems, it is important to know which sewer pipe slope is most effective for internal sewerage:

• the minimum sewerage slope according to SP 30.13330.2016 “SNiP 2.04.01-85* Internal water supply and sewerage of buildings” should be taken for pipes with a diameter of 150 mm – 0.008; 200 mm – 0.007;
• It is not recommended to set the slope too high, since solid masses will not have time to pass at the speed of the water flow.

Table of pipe slopes from 50 mm to 200 mm

Important! The document “Sanitary Norms and Rules” provides the minimum slopes of drainage pipes from sewer risers. A correctly set angle of inclination of the sewer pipe per 1 linear meter is extremely important for the proper operation of the sewer system. Properly laid drain pipes allow liquids to flow smoothly, which helps transport solids without clogging or clogging.

Connection

Only representatives of the water utility, management company or other utility authority can reconnect the drainage pipes to the system.
If the sewer system in the apartment was blocked using one of the devices (“Octopus”, “SOV”), you need to pay the debt, provide the accounting department with a receipt for repayment of the debt, and notify the responsible persons.

Then you should call workers who can remove the blocking device from the pipes. To carry out such work, you will definitely need special equipment; only professionals have it .

ATTENTION! Even if private companies offer to arrange illegal drains, advertising their services, you should not use their services. Improper work will lead to disruption of the sewer system throughout the riser.

In the case where there is no money to pay off debts, and the operation of the apartment requires sewerage, it is still better to use the services of craftsmen from a private company than to carry out the work yourself. Without professional knowledge and tools, it is easy to damage the common riser, which will make it impossible for the entire entrance to use drainage .

Sewage slope of 1 meter

Which pipes are better for heating? Pipes for heating a private house - reviews, price

For sewerage repair and construction, it is recommended to adhere to the following minimum calculated values ​​of the sewerage slope per 1 meter from SNIP:

• sewer pipe slope 110 mm - 2 cm per meter;
• pipe slope 50 mm - 3 cm per meter;

For example, for a 160 mm pipe, the optimal slope should be at least eight centimeters per meter. That is, there is a pattern: the larger the cross-section of the free-flow pipeline, the smaller the actual difference in levels relative to the clean floor at the beginning and end of the line.

When installing a sewer system, the appropriate slope is achieved using a special meter, which helps to adhere to the recommended level. The rail is placed on the pipeline, while the arrow of the device is directed along the flow of the wastewater, and the blue liquid in the bubble is leveled at a given level. This is how the slope of the sewer pipes is determined.

Measuring pipe slope angles

Important! When laying sewer pipes, the slope is determined not in degrees, but in hundredths. That is, by calculating the slope level of a sewer pipe of 50 mm, the desired digital value of 0.03 is found. The laying of waste pipes must be based on the requirements of the rules and not contradict them.

How are sewers blocked by law?

Housing and communal services workers do not have the right to use homemade plugs, which can easily damage communications and also cause damage to the debtor’s property . The industry produces several types of professional locking systems; the most commonly used device is the Octopus; the Kit device is also popular.

• The peculiarity of the "Octopus" is in its design and operation. It can take video of the device used to shut off the sewer system for non-payment, since a camera is inserted into the design. Such closure equipment can plug the pipe completely or partially. If the service is partially limited, specialists configure Octopus accordingly.
• The equipment must be installed through the ventilation hole; there is no need to disturb the geometry of the sewer pipes.
• The “Kit” system also has its own characteristics, the design of which includes LED bulbs and a compact control panel.
• For a long time, it has been manufacturing sewerage restriction equipment; its devices meet modern requirements for equipment of this type and are safe for installation in drainage pipes.

ATTENTION! If utility companies installed Sprut or other equipment without warning, you need to contact the management company or other responsible organization. But you shouldn’t fight with the water utility if you have debts for several months.

When installing plugs on a sewer pipe, the cost of the system, the material used to make the pipes, and other data are important. Each device has its own price; it can be found in a special equipment store. The fight against defaulters led to the release of such devices as SOV, GLOT, and TerminatorProfi.

How to calculate sewer slope

The slope of sewer pipes is the angle at which pipes are laid for the free passage of waste. Its adjustment requires a professional approach. However, anyone can calculate the height of the pipes, and a simple calculator and knowledge of the Pythagorean theorem will help him with this.

Copper pipes for heating: advantages and characteristics

At the same time, do not forget about some important points:

• if the angle of inclination of the pipe is incorrect, then during installation some problems may arise, leading to additional costs;
• with proper installation of the drainage system, when there is a blockage in the sewer system and there is a need to clear it, the tee itself gives direction to the inserted cable so that it does not rest and calmly passes to the very end of the pipeline;
• It is not recommended to strongly slope the sewer pipe in the house, because the water will flow away very quickly (the flow rate will increase), and solids may remain in the pipe.

Thus, the maximum slope of sewer pipes when laying horizontally must be done correctly. It’s a different matter with a vertical installation, when the wastewater falls down, and it doesn’t matter what it is: solid or liquid.

For information. The slope of the sewer system in a private house determines the location for the holes in the wall. There are quite a few videos on Yue Tube on how to calculate it.

Features of blocking utilities

How is the drain blocked, what is the debt for sewerage, what should consumers know about the procedure, what is the legality of shutting off?

IMPORTANT! Workers of a utility company have the right to turn off a sewer system or other pipeline only if there is a debt of two or more months. This is a requirement of Article 21 of the Federal Law “On Water Supply and Sanitation”.

If the payment is only overdue for a month, the housing office must wait for payment . Another point is that employees must block communications taking into account the rules of the process.

• Residents of the apartment must receive a notice of debts for sewerage with a specified period, amount and time allotted for solving the problem with debts.
• You should not just put the receipt in the mailbox, but hand it over personally. The utility company can also send an invoice by letter with an inventory of the contents.
• What should the management company do when the debtor has not responded to the notice? It is now permissible to limit the use of utilities and engineering systems at home. If the utility company installed a plug without warning, the consumer has the right to challenge what happened.

The management company can put a blank only if the account has not received funds from the debtors. But even in this case, you cannot shut off the water to a separate apartment .

To carry out a shutdown legally, you need to adhere to a few more rules of procedure. A drainage plug can be installed if the water supply system has straight sections without branches . There must be 0.8 m of space above the riser, and the overlap device must correspond to the material of the pipe.

ATTENTION! If the sewer system is turned off due to a debt, the consumer can check the legality of the process - the debt has been in debt for more than two months and compliance with all requirements for the installation of plugs.

Judicial practice, unfortunately, knows few examples of complaints from apartment residents due to the fact that the law on stubs was violated. But you should always defend your rights (not forgetting your responsibilities).

Slope for external sewerage

1. Almost all external sewerage works on the principle of gravity. The fact that the water flows downhill allows the wastewater to be discharged into a cesspool or street sewer without the use of any mechanical devices. In fact, forced main sewer lines are not permitted unless a special permit is obtained;
2. To ensure good throughput, 110 mm pipes for external sewage with an internal diameter of 100 mm are used;
3. The gravity flow trench for external sewerage should be 30 cm above the soil freezing depth; most often, pipes are laid at a level of one meter from the ground surface;
4. An insufficient slope angle of sewer pipes leads to failure of the sewer system;
5. In most cases, the material and products removed when dismantling a pipeline are not suitable as a proper material for a new installation.

Unit installation technology

The installation procedure can be carried out in different ways. This depends on the type of device. Let's look at the two most common options.

Installing an outdoor trap

The event is quite complex. Many people prefer to entrust it to specialists. If you want to do everything yourself, you need to do the following:

• We choose a place to install the filter. When choosing, be sure to take into account the layout of the plot and the possibility of carrying out any landscaping work in the future.
• We determine the size of the hole that is needed to install the equipment. Its depth should be such that the grease trap lid protrudes 3-4 cm above the surface of the ground, and there is solid backfill at the bottom of the pit.
• We dig a hole. At the bottom we will install a solid formwork from a mixture of cement and sand. The amount of cement in the solution is determined by the type of soil. For loams and sandy soils, a mixture diluted at a ratio of 1:5 will be sufficient. For more unstable soils, the amount of cement is increased.
• We wait until the poured base dries completely. Replace the grease trap body and secure it to a solid base using anchor bolts.
• We install plywood formwork around the device. This is necessary to prevent soil shedding. If the equipment will be operated in a cold climate, it is covered with thermal insulation material. Polystyrene foam or mineral wool are quite suitable.
• The outlet pipe of the device is connected to the drainage system. All joints are carefully treated with sealant.
• The inlet pipe of the device is connected to the sewer pipe. The joint is coated with sealant.
• We fill the free space between the body and the ground. Most often, the so-called backfill is used, that is, the soil that was previously selected from this place when digging a hole is poured into the opening.

Don't forget about the fun boner. It is necessary to remove excess gases from the sewer system. If it is expected that the load on the wastewater disposal system will be large, it is best to install not one riser, but two.

Outdoor grease traps are most often cleaned using pumps or special equipment. A fat accumulation sensor installed inside the device will warn you about the need for a procedure.

Installing a grease trap indoors

Installing a grease trap under a sink is much easier than installing it outside. To do this you will need to do the following:

• We determine the location for installing the device. This should be an easily accessible hard and level surface, if possible in close proximity to the sink or dishwasher.
• Set up a grease trap.
• We bring the outlet pipe into the sewer system. At the connection site, be sure to install the rubber gasket included with the device.
• We connect the inlet pipe of the device to the outlet pipe of the sink or to the section of the pipeline where the washing equipment and the sink are connected. Don't forget about the special gasket.
• We fill the grease trap with water and check its tightness. If everything is in order, replace the device cover.

Indoors, equipment is most often installed under the sink or in close proximity to the areas where the washing equipment and sink connect.

Gravity sewer details

In the manufacture of a home sewer system, pipes and fittings use various materials:

• PVC - products tend to crack and wear out from repeated cleaning procedures;
• Cast iron. Among the disadvantages, the following should be noted - parts rust and corrode much faster, they are characterized by heavy weight. One of the advantages is that cast iron pipes and fittings can withstand decades without fear of wear. For cast iron, there are no predictable future problems such as physical damage.

In addition, the difference in cost between cast iron and PVC products is insignificant.

Important! According to the rules, the use of cast iron products is strongly recommended in multi-storey buildings, because drain pipes or traps, for example, are repeatedly opened and closed for cleaning with a cable.

House trap with different connectors

For the functioning of a gravity sewer system at home, an important element is the so-called “trap”. The double vent piece is required at the end of the house drain and at the beginning of the sewer system.

The part serves two main purposes. Firstly, it creates a water barrier, keeping water at the bottom. This water barrier prevents sewer gases from entering the building from the public sewer. Second, the dual vent trap traps debris or harmful materials before they can cause a clog in the sewer system.

Important! If sediment or debris is blocking the drainage system of your home, it is much easier to clear the “trap” than to open all the sewer pipes.

PVC products

A cast iron sewer trap will last significantly longer than PVC. This is a good choice for the long term. It should be noted that PVC traps are not produced in finished form. They are assembled together from various parts, slightly bent pipes and two tees, as shown in the picture.

PVC sewer trap

It should also be noted that sharp and abrasive blades are mainly used for cleaning sewer pipes. When inserted into the trap, these blades come into direct contact with the walls of the trap. This is another reason why PVC is not recommended for use - due to possible damage.

Fan pipes

A sewer pipe is a part of the sewer system that connects the waste riser and the atmosphere. It is designed to perform the following functions:

• Removal of obscene odors into the atmosphere, which ensures a comfortable environment in the bathroom;
• Maintaining pressure in the pipeline. When draining a significant volume of wastewater inside the pipeline, the air is discharged, which is why the shut-off valves begin to work incorrectly;
• Preventing pipeline clogging. Thanks to the drain pipe, the riser functions much more efficiently, which protects the system from the return flow of drains during large volumes of work.

Getting rid of drain flies: cleaning pipes

The first and perhaps most important step in the process of getting rid of flies is cleaning the pipes. This is a preparatory stage, but an extremely necessary one. Because if you don’t do it, then even with the use of special means you will not remove the flies forever.

1. Identify the enemy and source of reproduction. Place pieces of duct tape around the sink, preferably close to the drain. You can even partially seal it. If in the morning you see dead flies on them, then you can move on to the next step.
2. Carry out mechanical cleaning of the pipes using a brush or cable. Make sure there is no hair, rotting food or other organic matter left inside. To do this, you can use, for example, a universal flexible brush for cleaning pipes.
3. Slowly pour boiling water over the drain: one pan of hot water is enough. It will destroy a significant part of the larvae and eggs.
4. Pour the chemical there. pipe cleaner. But, you should always read the instructions for use and follow its conditions. The chemical gel may need to be refilled several times a week.
5. Finish off the remaining survivors with a fly swatter!

And, only after you have cleaned the pipes, use special professional products. We'll tell you about the best traps, gels, growth regulators and other useful fly control products.

5 Helpful Tips for Killing Sewer Flies

1. Fortunately, flies do not fly far from the place they have chosen as their home, so infection spreads to all areas of the house in extremely rare cases. This is especially true if you address the problem as early as possible.

2. When cleaning pipes, use a wire brush. Use a brush to clean the pipe as deeply as possible. Don’t rely on chemistry alone: ​​you can’t do without mechanical action here either. Move the brush up and down to remove dirt from the pipe walls. It is advisable to add a metal cable to the brush.

3. By cleaning the pipes you will only destroy the egg laying site, but you will still have to fight the adults for about 20 days. Don't be alarmed by their appearance, it's normal! Just systematically finish off the singles. 4. Always store food in airtight containers around the house to prevent sewer flies from attracting them. They only live in shells, and can fly to different places for food. In the battle for food in the kitchen, fruit flies and sewer flies are definitely ready to compete!

5. When using even the weakest chemicals to control sewer flies, wear safety glasses and a mask to protect your health.

Safety requirements

When opening a house's internal sewer trap, if possible, you should ensure that the public sewer system is not connected. If the common sewer riser is connected and the trap is opened, the consequences can be catastrophic. The entire discharge of untreated sewage from the common building sewer will end up in the apartment. This could potentially cause significant damage with severe health consequences.

Even simple repairs, if done incorrectly, can cause extensive property damage. Therefore, even what seems like a simple plumbing repair task should only be left to experienced and licensed professionals.

Important! For those looking to save money and do the installation themselves, keep the following points in mind. Sewers and drains are intended for long-term use. When installed correctly, they require virtually no maintenance and operate without the use of any mechanical devices. Failure to comply with health and safety regulations for such an installation may result in undesirable consequences.

It is not necessary to make a slope if the drainage is carried out by pumping and not by gravity. However, in a system of free flow of wastewater, the slope is of decisive importance.

For long-term operation of a free-flow sewer, you need to know: firstly, what the slope of the sewer pipes should be; secondly, the depth of their placement. Calculation of sewer pipe slopes is carried out in compliance with the necessary standards. The depth of sewer pipes in a private house is approximately one meter. Only after we decide where, how and from what material we will lay the pipeline, will it be possible to begin its installation.

We exterminate flies in the bathroom using sprays and poisons

In cases of particularly active drainage flies, the following remedies will be useful to you. They perfectly complement traditional wrestling methods and professional chemistry. Such insect development limiters, aerosols and poisons can be perfectly combined with other existing developments. What else do insecticide manufacturers offer us?

Aerosol Raid

This insect activity regulator, like similar products, is a universal chemical. They can be used against ants, beetles, midges... if these creatures settle in some secluded places. The main feature of limiting aerosols like Gentrol Aerosol Insect Growth Regulator is their ability to penetrate the trickiest insect dens! A familiar picture: hundreds of ants crawl out of a small crack on the wall... Or small bugs begin to crawl out from under the floorboard at night! Just spray this “entrance” and the job will be done. The complex chemical formula literally “sterilizes insects.” Adults will not die, but will spread the “poison” throughout their nest and significantly slow down reproduction. A similar principle applies to drainage flies.

It dissipates into a light foam that fills the space like a building sealant. However, then you can easily wash it off and use the drain for your pleasure.

User Joe thanks the product for the complete elimination of flies and its long shelf life. And Kristine calls it the best “seasonal remedy” for insects. And all existing complaints relate to the fight against other insects: for example, water beetles, which many confuse with cockroaches. It turns out that the spray fights effectively against our patients.

Aerosol Raptor

Before us is a kind of mix between an aerosol and a drain gel. This liquid also uses natural microorganisms that destroy signs of decomposition, harmful bacteria, odors and insect larvae. True, it is used more often for “external use”. After all, the main function of this mixture is the destruction of harmful odors. Yes, yes, the developers managed to combine a cosmetic effect, pest control and prevention.

The spray can be used on walls, floors, carpets and wall voids, basements and trash containers. And also garbage cans, bathrooms, compost heaps and technical drains. They gave it a whirl, the mixture covered the “territory of war” in an even layer and began to do its job. Users claim that if the instructions are followed correctly, it can kill flies. Yes, the destruction efficiency is not as high as that of concentrated gels, but what versatility!

In general, this substance cannot be recommended as the main tool in the fight against “winged girlfriends”. But to maintain healthy home hygiene, especially when living outside the city, this thing will definitely come in handy.
