How to make a water seal

How to make a hydraulic shutter with your own hands? Sometimes an unpleasant smell may appear in the sewage pipes. To avoid this problem, you need to install a water trap.

Usually it is installed during the sewage system. This device not only prevents the formation of odors, but also serves as a check valve.

The hydraulic seal works by creating a water stopper in the drain, which becomes an obstacle to getting unpleasant odors into the room.

For installation, you can use a ready-made water trap available on the market, or make it yourself.

You will need materials and tools:

  • plastic pipe;
  • couplings;
  • knife;
  • screwdriver;
  • adjustable wrench.

You can make the device from a small piece of plastic pipe. The diameter of the pipe should be selected according to the diameter of the drain hole. First, it is necessary to bend this piece of pipe in the shape of the letter U.

Then it is necessary to attach to it the couplings of the corresponding diameter. After this, the device is connected to the funnel by means of couplings. It is better to choose couplings 6 cm high.

If there is such a possibility, the pipe is welded to the funnel of the sewage pipe. A water-type water trap was produced, which works at the expense of the water barrier.

In order for the device to perform its functions, it is necessary to pour a little liquid into the attached tube.

The water in the device functions as a settler: it prevents odors from entering the room from the sewage system.

Dry option

Principle of operation of a dry gate

The principle of the dry shutter.

Materials and tools:

  • plastic ball;
  • gasket.

A dry water trap is also used to remove odor from the sewage system. The design and principle of its operation are different. In such a device, dry material is used instead of water.

You can make a dry water seal yourself. To do this, you need to use a plastic ball, whose diameter is slightly larger than the diameter of the drain pipe. This ball is put into the drain hole.

Then it must be fixed around the edges so that it does not move to the sides. For this, a gasket must be put on the pipe. The walls of the gasket will hold the ball in the tube. The height of the wall above the level of the drain pipe is 5 cm.

The operation of such a device is quite simple. When there is water in the sewage pipe, the ball floats up and thereby prevents smells from flowing into the air. In this case, the drain is released.

When there is no water in the pipe, the ball simply lies on the pipe and closes the gas outlet from the drain.

Use this design can be not only in the apartment, but in the sauna or sauna. If in winter the ball is freezing to the drain, then this will not lead to a rupture of the pipe. In this case, the ball can be poured hot water, with the ice melting.

The principle of the organization of the hydraulic seal on the sewer

The principle of the organization of the hydraulic seal on the sewer.

A hydraulic stop with a water stopper stops working if the sewage system is not being used. If you have not been in the apartment for more than a month and have not turned on the water, the water barrier disappears and lets the air out of the sewer.

Therefore, if, for example, you do not live in the country in winter, you sometimes need to come there and open a water tap to keep the device in working order.

It is possible to install a ready-made water trap. There are the following types of hydraulic seals for sewerage:

  • bottle;
  • tubular;
  • corrugated.

Bottle hydroseater performs its functions better. It can be disassembled and cleaned from blockages if necessary.

When replacing parts, this design is very convenient. In the event that you dropped any small items or jewelry in a bath or a sink, such a siphon will keep the desired object.

Tubular and corrugated devices are made in the form of a flexible plastic tube. The tubular siphon is large, therefore it is used less often.

The corrugated siphon is smaller, it can be adjusted, so it is more popular.

Installation

A set of mounting tools for mounting the hydraulic seal

A set of mounting tools for mounting the hydraulic seal: mounting brackets, support nut, FUM tape, gas wrench, insulation tape.

Materials and tools:

  • mounting brackets;
  • lock nut;
  • silicone sealant;
  • лента ФУМ;
  • drill;
  • cement;
  • sand;
  • clay;
  • gas key;
  • screwdriver;
  • сливная грижетка;
  • sealing ring;
  • insulation tape.

First you need to put a grate in the sink. It is tightened tightly with a nut.

Then the device is connected to the drain and tightly tightened the lock nut. In the case where the kitchen sink has 2 compartments, install a siphon, which has two drain pipes.

The structure of the siphon includes the following elements:

  • tee;
  • union nut;
  • bolt;
  • cap.

Usually a device with overflow is installed under the bath. Before the place of combining the siphon and the pipe, a tee is mounted.

To him, screw the overflow pipe. This pipe is used to drain water when the bath is overfilled.

There are hydraulic seals with automatic drainage. In this device, the overflow grid and the drain grid are connected using a cable. When the bath is overfilled, a cable will open with a cable.

When all these operations are completed, you need to connect the siphon and sewer pipe. If it is made of metal, then it is disconnected from the hydraulic seal.

The diameter of the branch pipe of the hydraulic seal is smaller than the diameter of the socket of the sewage system, which has the shape of a funnel.

Therefore, it is necessary to put a sealing ring on the branch pipe having a thickness of 1.5 cm. The outer diameter of the sealing ring is equal to the cross-section of the socket at a distance of 10 cm from the edge of the socket.

After connecting the siphon with the sewer, it is necessary to seal all joints and joints using an insulating tape.

Siphon, which is installed under the sink, must be firmly connected to the sewer pipe without gaps. To do this, lubricate the sealing ring with a silicone sealant.

Using this manual, you can install a self-made water trap.
