Rubber sealing cuffs for toilet bowl: eccentric with offset

Installing a toilet with your own hands is not that difficult. To do this, you do not need to be a trained plumber with extensive experience. It is enough to have the desire and be informed about the difficulties of doing this work.

One of the problems that everyone may encounter is the displacement of the sewer hole to one side. This problem is solved by a toilet cuff, which has its own connection details. We will talk about how to work with the cuff in this article.

Types of cuffs

A piece called a toilet cuff or coupling is needed to connect the toilet outlet to the sewer pipe. Depending on the form it is:

corrugated;
eccentric (it is called a toilet eccentric);
conical;
smooth straight line;
smooth corner.

Models differ in diameter, length and material of manufacture. The diameter of one end must correspond to the size of the sewer pipe (most often 110 mm), and the second - to the toilet outlet channel. With a direct connection, you can choose a conical toilet cuff, the end of which gradually tapers.

The advantages of corrugation are that it can be used in difficult situations when the holes are strongly offset relative to each other. The corrugation can be rotated at the desired angle and stretched a little. However, its walls are quite thin, so many people prefer to use an eccentric or a straight smooth adapter.

The eccentric consists of two cylindrical surfaces with offset axes. This shape allows you to hermetically connect holes that are unevenly opposite each other.

Sometimes the parts are combined, ensuring the tightness of the connection, since it plays a very important role in the drain.

Toilet cuffs are made of plastic or rubber, white, gray or black. It is clear that white is more preferable for aesthetic reasons. Rubber couplings are used primarily for cast iron pipes; in other cases, plastic is used.

Types and purpose of cuffs

Cuff white

Initially, it is important to know what this element is, what materials it is created from, and also in what main varieties it is presented. The cuff is two cylindrical surfaces that are reliably and firmly connected to each other, as a result of which their longitudinal axes are located in a certain plane to each other.

This element is usually created from polyethylene or polypropylene, since these materials make it possible to create truly sealed devices that can easily cope with the tasks, which primarily include the formation of sealed connections. Also, from these materials you can easily obtain cuffs that will have an unusual and unique shape, so for a specific non-standard toilet you can always choose the appropriate element.

There are two main types of toilet cuffs:

The eccentric is called a straight cuff, and at the same time it has a standard shape and configuration, due to which it is most often used for standard toilets that do not differ in any specific parameters.
The main function of such an element is considered to be the process of connecting the toilet outlet to the sewerage system, and in this case ideal tightness and reliability will be achieved. Eccentric cuff
The corrugated cuff usually has a specific shape, but its installation can be done independently. Typically, this option is chosen if the plumbing fixture itself has exquisite and unusual shapes, making it impossible to use a conventional straight cuff. The fact is that the corrugation has excellent flexibility and elasticity, so you can install it at different angles and in the most difficult situations, so you can install the toilet anywhere in the room where it will be most convenient to use it.

Selecting the right model

If the toilet outlet is vertical, then you can use the simplest straight cuff. Corrugated or eccentric models are not needed here, since the toilet is placed on top directly at the outlet of the sewer pipe. But vertical outlets are rarely found in apartments and private houses.

For horizontal release, you can take a straight short cuff or a corrugated one in the middle.

Note! If the inlet and outlet are shifted relative to each other in height, then you need to take an eccentric model.

There is also an oblique type of release. It can be connected to the sewer using different samples. The specific type of connecting part is chosen depending on the location of the toilet.

Practical advice

Finally, take on board some useful tips from professionals that will help you avoid possible problems when installing the cuff or preparing for it. First, try to minimize the distance between the sewer pipe and the socket. If this is technically impossible or impractical, try to strengthen the corrugation as best as possible. This can be done using special supports.

If you use a fairly short cuff, you should not stretch it before installing it in the system, since you can accidentally stretch it and it will simply sag during installation.

Advice. If we are talking about using a cuff in the sewer system of a private building, pay attention to the presence of tailed “guests”. If any are present, it is better to use the standard option - a cast iron elbow.

This concludes our acquaintance with the existing types of toilet cuffs. Enjoy the shopping!

How to replace a part

The cuff needs to be changed if it cracks, as well as when replacing an old toilet with a new one. If water begins to leak during descent, repairs should be made.

To properly connect the drain pipe to the toilet, you need to put the plumbing fixture in place and check the connection. You can attach the cuff and make sure that it fits perfectly in size.

Important! The sewer pipe outlet must be cleaned. All surfaces to be joined must be dry.

First, a connection to the sewer is made. Sometimes a seal is additionally placed in front of the cuff. To ensure that the joints are waterproof and tight, adhesive sealant is applied to the joining surfaces. But some specialists do without it.

Then connect the toilet output. Place it on the floor and mark it (at the same stage you can check the drain by flushing the water). After which they are temporarily removed to drill holes for fastening. And they are finally installing it.

It is convenient to use an eccentric with a corrugated insert for installation. If the installation is not done very accurately, then the corrugation can be stretched a little and it will take the desired position. Experts do not advise stretching a corrugated pipe to the maximum, because it becomes inelastic and quickly becomes unusable. The corrugation should not sag, otherwise its functions will be disrupted and blockages will form. At the end of the installation, it is necessary to carry out a control drain of water to make sure that everything is connected correctly.

Installation or replacement of the eccentric

Sequence of actions when installing an eccentric

Installing the cuff is one of the required steps. The element will need to be replaced when leaks appear - a signal that the old part is worn out. The stages of work in both cases are identical.

When replacing, the first step will be to clean the connecting surfaces: the sewer pipe pipe and the drain outlet of the bowl. After this, all elements are thoroughly dried - this will ensure the tightness of the connection of the parts.

Then proceed directly to installing the eccentric. A marker on the floor marks the location of the toilet. Afterwards, it is moved to the side for ease of installation of the cuff. The part with the seal inside is fixed to the sewer pipe.

The next step is to return the toilet to the place marked with a marker and connect the other end of the cuff to the sewer pipe. If the size is chosen correctly, there will be no problems with installation. The structure will lock in place without much effort. When working with a non-standard drain shape, the corrugated part of the cuff is carefully rotated to the desired position, trying not to damage the integrity of the surface.

The application of sealant in order to increase the strength of the fastening is carried out immediately before attaching one and then the other end of the cuff. However, some craftsmen do not consider it necessary to use silicone sealant, arguing that the quality of modern eccentric cuffs does not require increasing their moisture resistance.

After the composition has dried, at least half an hour should pass. To make sure the structure is tight, several buckets of water are poured into the bowl, and paper is placed under the connecting seams. If after checking no leaks are found, the plumbing fixture is secured to the floor with screws.

Cuff for cistern

In some toilet models (non-compact), another cuff is used - between the flush cistern and the bowl. It serves as a seal, preventing leakage. To install a separate tank, you must first pull the cuff onto the toilet extension shelf and secure it with a clamp. Then pull the other end of the cuff onto the tank drain pipe, also tighten it with a clamp or wire and screw on the shelf.

If the cuff begins to leak, then you need to inspect it; often these parts crack and break. In this case, they must be replaced with new ones. If there is no visible damage to the part between the tank and the toilet, then you can tighten the bolts to strengthen the fit. Rubber and plastic cuffs are cheap and are always on sale, so there will be no problems with repairs.
