Connecting the toilet to the sewer. The scheme of installation of a toilet bowl

Connecting the toilet to the sewer with your own hands - the procedure is not as complicated as it might seem at first glance. When you do it, you need to do just three things - to give stability to the toilet itself, connect the outlet to the sewer pipe and connect the water pipe to the drain tank. Suspended plumbing fixtures are installed a little differently - on the frame. However, this work is also quite feasible without the involvement of specialists.

New plumbing: toilet installation

Installation of purchased plumbing is done in several stages:

• Old equipment is being dismantled - the tank and the actual "seat" itself.
• If necessary, the board is changed.
• A new toilet is installed. At the same time, the connection to the sewage system is performed.
• Mounted and connected to the water supply tank.

Preparatory work

Before you start the operation such as installing and connecting the toilet to the sewer, you should prepare the bathroom itself. Previously, it is necessary to take out all the furnishings that might interfere with the installation work. Also, to prevent leakage of water and flooding neighbors, common cranes overlap.

Dismantling of the old tank

First of all, disconnect the drainage tank from the water pipe. Usually the tanks are connected to it by a flexible metal hose. If there is a valve on the branch from the pipe to the drain tank, it should also be closed. Then unscrew the nut, fixing the hose to the water supply, and then the nut of the fastening to the nozzle of the tank.

How to remove an old toilet bowl

After the tank is turned off, proceed to dismantling the plumbing fixture. Pre-release the old toilet bowl disconnected from the branch pipe branch of the sewer pipe. The method of dismantling depends on which method was used for fastening. It can be connecting the toilet to the sewer with a corrugation or a box. In any case, there should not be any difficulties with their dismantling.

On the sides of the base of the toilet there are two holes, from which it is necessary to unscrew the bolts. After the equipment is disconnected, it is set aside and the condition of the mortgage board is checked. If it is damaged or rotten, replace it. For this, the old board is removed and discarded. The niche is thoroughly cleaned, if necessary expanded, poured with a cement mixture and pressed into it a new board corresponding to the size of the "foot" and the base of the toilet bowl.

In the event that the floor in the bathroom is tiled, and under the old one, and under the new plumbing fixtures, it is worthwhile to put a rag (so as not to scratch the cover).

Toilet bowl installation: instruction

After the old equipment is dismantled, proceed to install a new one. In the mortgage board drill holes - at a distance corresponding to the holes under the fasteners in the base of the toilet.

Plumbing device is put on it and screwed with long screws. Holes in the board should have a diameter slightly smaller than that of the rods. Screws of screws can be covered with special plastic or steel decorative pads.

Basic rules for connecting to a sewage pipe

At the moment, only three types of toilet bowls are available: with horizontal outlet, oblique and vertical. The bell flare from the riser in ordinary city flats usually comes out at an angle. Connection of the toilet bowl to the sewer is made depending on the type of its outlet and the position of the branch pipe of the drain pipe. In this case, various elements are used as adapters: cuffs, branch pipes or corrugations.

Rules for installing instruments with outlet at an angle and horizontal

Since the toilet bowls with horizontal outlet or oblique are most often used, let us consider the connection scheme in more detail. If the outlet of the bowl and the socket of the pipe are coaxial, plastic connections are used for the connection. In the case of small inconsistencies, eccentric cuffs are used. Minor discrepancies are usually caused by the displacement of the toilet when attached to a board or tile. For serious deviations, corrugation is used.

Previously, as already mentioned, the installation of a toilet bowl (with oblique release or with horizontal) is performed on the board. Next proceed to the actual connection. The issue itself is smeared with a surrey and wrapped with a resin strand so that its end is 0.5-1 cm long from the outside. If it is poured into it, it may become an additional cause of blockages later on. Then the connecting element - corrugation or coupling is put on top. The opposite end is greased with a sealant and inserted into the socket of the sewer pipe.

Functional Testing

Further, irrespective of whether the connection of the toilet bowl to the sewer was carried out by corrugation, a cuff or a branch pipe, a check of the drain for leaks is carried out. It is very easy to do this. You need to pour water into the bucket (since the cold tap is closed, you can hot, but it's better to do it in advance) and gently pour it into the toilet, while watching whether there are any outlets in the outlet and leakage socket. If everything is done correctly, such a problem will hardly arise.

Use the toilet can really start no earlier than 4 days. It is such a period of time that sealant is necessary for the final hardening.

Connecting the tank to the water supply

So, how to connect the toilet to the sewer, we have found out. After this procedure is completed, proceed to install the drain tank. It is fixed according to the instructions supplied by the manufacturer to the plumbing fixture itself. At the next stage, you will need to connect the tank to the water supply. In this case, everything is simple. For connection, an old hose can be used by screwing it to a drain tank and a pipe outlet with cold water.

Tighten the nuts tightly, but try not to break the thread. Both for dismantling and for installation, a simple adjustable wrench is usually used . After the hose is screwed, open the water and check the connection points for leaks. If any, it is most likely in the old hose. It will need to be replaced simply, it's worth it inexpensively.

Installation of a toilet without a board

Sometimes the toilet is not installed on the board, but directly on the tile. In this case, holes in the fasteners are simply drilled in it. Next, a linoleum liner is cut from above, cut out in the shape of the section of the base of the toilet bowl. The latter should be glued to the floor with a sealant. However, after the device is similarly installed, it must be seated and rocked. If it is unstable, the tile underneath it will still have to be removed and a wooden, level base installed. Connecting the toilet to the sewer in this case is carried out in the usual manner.

Suspended plumbing

Recently, many apartment owners prefer to install in the bathrooms models that are not attached to the floor, but to the wall. These toilet bowls look more stylish and modern than ordinary ones. In addition, this solution makes it easier to clean the toilet. In this case, the landlady does not need to wash the toilet leg and its base. It's enough just to wipe the floor under it.

Of course, to connect the toilet to the riser in the usual way in this case does not work. All pipes for sewage will be clearly visible, which is extremely unaesthetic. Therefore, the hanging toilet bowl is hung on a special steel frame. Next, they perform the liner and frame the frame with gypsum boards, thus arranging a false wall covering all communications.

Assembly diagram

Well, now let's take a closer look at how to connect the toilet bowl to the sewer. Frames for such plumbing fixtures are sold separately. In their design, special brackets and screws are provided, by means of which the position of the frame on the wall and on the floor can be adjusted. In another way, the frame is also called an "installation".

So, the scheme of installation of a toilet bowl in this case is those:

• The drain tank is fixed on the frame.
• The marking under the frame is in progress. Usually it is fixed in two places on the wall and in two - to the floor.
• The tank is connected to the water supply.
• Next, the frame is fastened with the verification of its horizontal and vertical level.
• Mounted decorative box of plasterboard sheets.
• The toilet itself is installed.
• The drain is being assembled.

Basic rules for installing the frame

Before fixing the frame, check that you have correctly hung the tank. In the end, the drain button should be located at an altitude of about 98.5-100 cm above the floor level. The toilet itself, which will be installed later, is at a height of 40-42 cm. The sewage pipe is approximately 20 cm. You can also select the desired position after installation, by adjusting the screws to the floor.

To the wall, fixing is done so that there is a small gap between it and the drain tank (about 1.5 cm).

Water connection

This procedure is no different from the installation of conventional toilet bowls. The only thing - flexible metal hoses in this case is not recommended. The fact is that they quite often fail. If it is a question of an ordinary tank, the replacement will not be difficult. However, it is very difficult to remove the hose from under the false wall behind the hanging toilet. Therefore, in this case it is better to use the piping from a piece of plastic pipe. The design of the overflow toilet bowls is usually such that you can connect it if desired, both from above and from the side.

Before beginning the plating of the frame with gypsum plasterboard, it is also necessary to fit the sewage pipes (branch pipe) to the toilet outlet - by means of the same nozzle or, as a last resort, the couplings.

Gypsum boardboarding

Before installing the decorative box, the pins are screwed to the frame, which will then need to be attached to the toilet itself. To make the base of the false wall, you should use a moisture-resistant plasterboard with a thickness of at least 1 cm. When cutting it, it is necessary to provide holes for the drain button, corrugation and pipes. On top of the box is usually trimmed with ceramic tiles.

Toilet seat installation

Mount the plumbing device itself can be no earlier than two weeks after the tile is laid. The output of the toilet bowl is fastened to the socket of the sewer pipe with a branch pipe. The same "seat" is pulled together by nuts on the pins. The joint between it and the tile of the false wall is smeared with silicone sealant.

At the final stage, drain the water to check the connection of the toilet bowl to the sewer system for leaks. At this work on the installation of sanitary ware can be considered complete.

As you can see, the procedure for installing the toilet bowl is quite simple. After starting the assembly, you will see for yourself. The main thing is to carefully seal all joints and prevent leakage through a pipe or a drain hose. Of course, and the toilet itself, in the event that it is floor, should stand smoothly, not swinging.
