How to connect the bath to the sewer: a guide
Installing and connecting the bath is not too complicated, but there are a number of nuances that need to be taken into account both during preparation and during installation.
Bath installation

Much depends on the material of the bath:
- Acrylic baths are very popular because they have a variety of shapes and colors. But they can sag, and therefore need to install a strong substrate. To do this, use a brick, foam concrete blocks or timber. However, if the kit is provided with a metal frame and various trim elements, only proper adjustment will be needed.
- Steel baths are also subject to deformation and require the construction of a frame structure with the use of foam.
- The most reliable are cast-iron tub legs, which are easy to adjust.
The choice of location and materials
Together with the purchase of a bath, it is important to select the appropriate siphon. This device has the necessary openings for draining and overflow.

Attention should be paid to the drain pipe, which is connected to the siphon. It is better to abandon the corrugated, because it has a number of drawbacks. And this is associated not only with high hydraulic resistance, but also with the ability to quickly accumulate dirt. In addition, it is difficult to clean.
If the diameter of the standard drain pipe will be less than the sewer pipe, then an adapter will be needed that allows you to go from standard 40 to 50 mm.

After choosing a place for the bathroom should pay attention to the high-altitude drop. The exit from the bath should be at least 10–20 centimeters taller than the entrance to the sewer. Otherwise, the water will stagnate, so it is important to check the height of the siphon.
Tip! It is desirable that during further operation access to the siphon should always be free. From time to time he may need to be cleaned of dirt.

A rigid pipe of two knees with turns is better suited for connection. But if it cannot be installed, then a corrugated pipe can be used. If the sewer system consists of cast iron pipes, you will have to purchase a 73/40 rubber sleeve.
The sewage system of plastic pipes needs to be connected to a separate pipe with a diameter of 40 mm. It can be both flexible and rigid, but must also be made of plastic.
Connection procedure
Tip! When assembling a siphon, special attention should be paid to sealing gaskets. It is very important not to forget about the washer that should be placed between the overflow casing and the bathroom. Before installing it must be lubricated with sealant.

Since in recent times a lot of fastener parts are made of plastic, you should work more with your hands without using tools. After all, a strong constriction simply breaks the right part. The fork wrench is needed only to tighten the throat of the main release and overflow.
One end of the mounted siphon is attached to the pipeline, and the other to the drain hole of the sewer.

Tip! It is very important to check the tightness and tightness of the connection all the time. It is better to fix the problems immediately to avoid water leaks.
If the bath is literally installed against the wall, you will have to use sealant. They need to seal the joint between the board and the wall. It is undesirable that the water all the time fell under the bath.
After connecting to the sewer hole, you should once again check everything for leaks and proceed to the next step.
