Check valve for sewerage: air, pipe installation, odor from the toilet, stop, sanitary, water seal 110

Check valve for sewerage - a mandatory element to prevent return of drains back to the apartment To control the pressure in the sewer use a bypass and check valve. The installation of the shut-off system is regulated by regulations and prevents return of drains back to the premises. In addition, the reverse device performs a number of other important functions.

Types of valves on the sewer pipe

Check valve installingIt is installed on the sewage system to block the raising of drains and their leakage from plumbing fixtures. If you do not install a hydraulic seal, then you can suffer serious losses in the future. Because there are no obstacles for waste.

Types of valves for sewers:

• Reverse sewer valve;
• Vacuum( air) sanitary valve.

The principle of the device is to block the passage of the pipe by means of a diaphragm valve under the action of air pressure. The valve circuit includes an overlap membrane. It creates a block for the reverse raising of drains. Also, the device includes a drainage lever and a cover that is used for cleaning.

The sewer valves can be of two types:

The check valve must be installed on the first floor in apartment buildings. If the riser is soiled, this is the only way to protect the apartment from flooding with waste.

The hydraulic seal performs several important functions. He performs a protective role, preventing the flooding of the house. Also, the check valve blocks the unpleasant smell coming from the sewer. Thanks to the protective element, parasites and rodents will not penetrate into the apartment. Because of this, the valve received the nickname "anti-lock".In this case, the non-return valve is divided into several types: lifting, ball valve, rotary, wafer type.

Features of the air valve on the sewer

The SNiP regulations require the installation of an air valve for each sewage. If it is not possible to install an exhaust valve, use a vent. Installation of the vacuum device is carried out on a pipe with a diameter of 110 mm.

Air Valve Diagram:

• Equipment housing;
• Vent for air flow;
• Pressure regulating stem;
• Gasket of rubber;
• Cover of the device.

The vacuum valve operates according to the following principle: equalization of atmospheric pressure in the pipe, suction of excess discharged air. When the water gets under a certain pressure into the drain, the shut-off valve cover opens. If the pressure stops, the spring that closes the cover is triggered.

The air valve performs several functions simultaneously

The air valve performs an important function - noise protection.

The ventilation device is available in different materials. The most popular is plastic. It guarantees easy installation, easy to clean, easy to clean, inexpensive, durable.

Types of air valves:

1. Automatic. Has a small bandwidth. Used in private homes for individual parts of sewerage. It releases air that accumulates in the system.
2. Antivacuum. The most popular species. Used for different purposes. Releases and lets in air.
3. Combined. Combines the functions of automatic and anti-vacuum type.

Each species is selected for the features of the room. Most often use a combined view. It is installed on the drain in the bathroom, in the kitchen.

Installation of the air valve on the sewer from the smell

To protect the apartment from the unpleasant odor use an air valve. Its installation is quite simple. It is necessary to mount it on a free part of the plumbing pipe.

Sequence of installation of the vacuum valve:

1. We choose a place for the installation of the valve. The valve can be installed on any part of the device and for the entire sewage system. The air mechanism is installed at a distance of 20 cm from the proximal siphon and 30 cm from the pipe.
2. We fasten the valve pipe to the selected method. Can use fittings, threads.
3. We check the tightness of the installation.
4. Operation of the sewerage system.

Stop valves are mounted inside the room, as they are used at a temperature of at least 0 degrees. The device quickly pays for itself, as it protects the plumber from breakdowns, and the apartment from unpleasant odors.

Air Valve Installation

Operating problems can be caused not only by valve failure, but also by changes in the sewage system. For example, when installing a washing machine.

Thanks to the air valves in the apartment not only does not spread unpleasant odor, but also noise. This is a significant advantage of the device. Thanks to this, the house creates the most comfortable conditions.

Characteristics of a non-return valve for WC

The non-return valve has the appearance of a special element that is mounted on the riser pipe. This part has a round shape, and the diameter coincides with the size of the pipe.

Characteristics of the non-return valve for the toilet:

1. The device is mounted not only on the toilet, but also on other plumbing fixtures;
2. The valve prevents the drains from entering the room;
3. The hydraulic seal blocks the penetration of an unpleasant odor into the room;
4. Required for installation on the first floors of apartment buildings.

Mounting the check valve on the toilet seat is not an easy task. The shut-off device can be mounted on the entire sewage system. Here you need to choose the right type of device and the place where the shutter is best able to cope with the tasks.

The non-return valve for the toilet is installed quite simply

Use a non-return valve only in a room with a positive temperature. In the cold, the device will not work.

Also, installation can be carried out on one device. They are served by a toilet bowl. It is through it that drains can get back to the apartment. Also a shut-off valve for reinsurance is installed on a sink or bathtub.

For long operation, the mechanism must be cleaned periodically. The reinforcement cover is easily removed and the necessary measures are taken. Also, the mechanism is equipped with a shut-off valve, which makes it convenient to shut down the systems and perform cleaning.

Shutoff valve for sewage

For valves, various materials are used in the manufacture. Use stainless steel, cast iron, plastic, bronze. A part with a similar pipe material is bought. Most often they are plastic.

In addition to cleaning the non-return valve does not require any other maintenance.

The pipes in the living room are normally 50 mm in diameter. The same size is acquired by the shut-off valve. The device has a special cover for easy cleaning and a lever for closing the flow of drains by yourself.

Shut-off valve for proper operation can serve for a very long time

Constituent parts of the check valve:

• Connection piece - used for fixing to the pipe;
• The main part of the lock is a locking mechanism;
• Limiter retainer;
• The final part is used for fixing to the pipe at the outlet.

The locking device can be used for 50 years if used correctly. Unlike the purpose of the application, I distinguish between different valve sizes. Devices with a diameter of 50 mm are used for pipes, 110 mm for toilet bowls. Air valves are also used to prevent unpleasant odors.

When choosing a valve, pay attention to the strength and reliability of the structure. The material must be able to withstand an aggressive environment. The cover in the valve should be easily removed for cleaning. Also, a lever must be provided for self-closing the sewage system.

Often use a water shut-off valve to determine the direction of water only one way. Such a mechanism is useful for self-priming pumps and autonomous water supply. The shut-off valve prevents the fluid from returning, which is pumped out by the pump, back into the well or borehole.

Installation of a non-return valve for sewerage

Installation on a drain system first involves the correct choice of location. It is important that the valve was accessible. For its normal operation, it is necessary to periodically inspect the device and clean it.

When buying a locking mechanism, do not rely solely on the price index. A cheap model will not please with quality, and with a breakdown will lead to serious losses. After installation, make sure that the device is sealed. If it is broken, then the device is not of high quality.

When buying a non-return valve, it is necessary to pay attention to the installation method. As a rule, many models are universal for all pipes. But there are options only for horizontal or vertical pipes. Also take into account the diameter of the valve.

When choosing a check valve for sewerage, attention should be paid to the installation method

Steps for installing the check valve:

1. Cut the length of the valve at the installation site;
2. The gate element is connected to the pipes;
3. It is necessary to pay attention to the directivity of the arrows on the body, which must look towards the outlet;
4. After installation, joints are processed with a sealant.

This completes the installation and the device is ready for use. If a noticeable noise is heard during operation, then the problem is in poor tightness. It will be necessary to replace the element.

A shut-off valve is required to prevent overflow of waste water through the toilet bowl or other sanitary nuts. With the help of a special membrane, it controls the pressure during the descent of water and protects the equipment from unpleasant consequences. With a non-return valve, you can not be afraid of unpleasant odor or rodents. They will not overcome the barrier.
