Connecting to sewers: options for competent work

Most often, to connect plumbing to sewers seek help from experts. However, if you do this work yourself, you can save a lot, and most importantly - be sure of the quality of the work done. Therefore, in this article we will look at how to connect the bath to the sewer, toilet and other sanitary appliances.

General information

Before proceeding to the description of the connection of sanitary devices, we will briefly consider the structure of the sewage system. So, the internal network consists of the following elements:

Thus, any connection of plumbing to the system begins with the pipe installation from the riser. However, if we are talking about a private house, then first of all it is necessary to run an external sewage system.

It should be noted that the connection to the central sewage system of a private house is carried out with the permission of the relevant local authorities. Moreover, such work should be handled by experts.

However, if the house is connected to an autonomous system, you also need to obtain permission from SES. Unauthorized connection of the sewage system in a private house can threaten a homeowner with a fine.

Thus, the connection of sanitary devices is the last stage of the internal sewage system.

Plumbing connection

Baths and showers

So, first of all, let's look at how to connect the bath to the sewage system with your own hands. It should be noted that this operation is not a big deal, however, in order for the drain system to work properly, it is necessary to take into account some nuances.

Before starting this work, you need to purchase a special siphon, which has not only a drain for drainage, but also an overflow hole. As a rule, the price of such siphons is not very different from the usual ones intended for sinks.

Tip! When purchasing a siphon, it is better to give preference to a model with smooth tubes. They can be flexible or made of plastic. The corrugated pipe will quickly get clogged.

Further instruction is as follows:

• The first step is to collect the siphon according to the manufacturer’s scheme.
• If the pipeline in the apartment is plastic, the siphon is connected to the sewage system by means of a flexible or rigid pipe with a diameter of 40 mm. To ensure a tight joint with a pipe of larger diameter, a special adapter should be used.

If the house has cast-iron pipes, a plastic siphon tube is connected to them with a rubber rubber coupling. All joints must be sealed, otherwise the bathroom will have a characteristic unpleasant smell.

• After assembling the siphon, it is fixed under the bath, at the drain hole. The outlet is connected to the drain hole.
• The end of the pipe that goes from the siphon is inserted into the sewer pipe.

This connection of the bathroom to the sewer is complete. As for the shower cabins, their connection to the system is performed in almost the same way. The only thing the shower stalls are most often made of corrugated pipes, which allows you to connect them in the most convenient place.

Note! Before installing the cab, you should read the instructions from the manufacturer, as in different models there are some nuances that must be considered.

Sinks and sinks

Most often connect the sink to the sewer is carried out at the final stage of repair.

Work is performed in the following order:

• As in the case of the bathroom, the connection is made with the help of a siphon - this is an indispensable element of any plumbing fixtures, as it provides a water seal. It should be noted that the siphons are of different designs, so their assembly should be performed according to the scheme that is attached to the device. The exception is corrugated pipes, which are simply bent by the knee and fixed by holders.
• Next, the siphon is fixed on the drain hole. Before you connect the siphon to the sewage system, you must make sure that all gaskets are in place so that the drain does not leak.
• Next, the siphon is connected to the sewer pipe using a coupling.
• After all installation work is completed, you need to let water into the system and check all connections for tightness.

Note! Siphon should be tightened carefully, without excessive effort, so as not to damage the plastic parts.

The connection of the sink to the sewer is also performed in the same way. The most important thing is to ensure the tightness of all connections.

Toilet

Connecting the toilet to the sewer system does not cause any problems.

The work is done in this order:

• Connecting the toilet to the sewer system is carried out using a corrugated drain. Before you put the rubber seal corrugations on the toilet nozzle, it is pre-moistened with water.
• Next, the toilet is installed on the selected location.
• The second end of the corrugations is connected to the sewer pipe.
• After that, the device is fixed on the floor.

Tip! Before you buy a new toilet, you need to carefully examine the old one. The fact is that the withdrawal of waste can be carried out at different angles. If the outlet does not match the location of the pipe, it may cause some difficulties connecting the device.

Connecting the installation to the sewage system is somewhat more complicated. Recall that the installation is a toilet, communications and the tank which is hidden by the panel (false wall).

In this case, the metal frame is pre-installed, after which the layout of the device is marked. After that, the nozzle is brought to the place where the toilet nozzle will be located.

The toilet itself can be floor or wall mounted, fixed to the frame.

Bidet

Bidets come in two basic varieties:

• Ordinary models;
• Models with upward flow of water.

The connection of a conventional model to a sewer pipe is carried out according to the same principle as connecting a sink:

• First of all, the siphon is connected to the neck of the bidet. Threaded connections must be screwed tight by hand to prevent damage to the instrument.
• The outlet pipe must be pulled out from the rear.
• Then the connecting pipe (corrugation) must be inserted into the sewer pipe.

If the model is connected with an upward flow, then, first of all, the water supply adjustment mechanism is connected, after which the device is connected to the sewage system in the same way.

As in the case of the sink, in the bidet you need to run water and check the connections for the absence of leaks. If no where does not drip, then connect the bidet to the sewer is made qualitatively.

Here, perhaps, all the main points that you need to know for self-connecting plumbing fixtures to the sewer system.

Conclusion

As we found out, it is quite possible to connect plumbing to the sewage system without the help of specialists. Of course, in practice, everything looks somewhat more complicated than in theory, however, with all the difficulties that may arise in the process of work, every home master can cope with it.

The main thing is to pay attention to the joints of the joints so that they are made tightly. From the video in this article, you can get more information on this topic.
