Today, without sanitary facilities, living in a house cannot be considered comfortable. When building a house, a construction project is necessarily developed. There are no unnecessary trifles in this case, here every detail performs its function. This applies to pipes, additional fittings and aerator.
A sewer aerator is one of the components of sewer ventilation.
The main task of the aerator is to prevent unpleasant odors from entering the middle of the room.
In addition, a sewer aerator creates a certain pressure inside the sewer system.
By the way, the aeration valve for sewage is also called vacuum and air. These are all homogeneous names, but it is more correct to call such a device an aerator. After all, this is the name used by specialists in the field of sewer networks.
The main functions of the aerator: 
- Prevents the penetration of different types of gas into the room.
- Creates a certain pressure in the sewer system.
From the words of experts, we can conclude that the second function of the aerator is the most important and necessary. After all, the pressure in the sewer system can be dangerous to human life, and the aerator is able to maintain the required pressure indicator. The principle of its operation is to normalize the pressure in the sewer riser if it starts to drop. Therefore, you can buy an air valve for the sewer, if it has not been there yet.
Places for installing an aerator
The aerator can be installed in a toilet, bathroom or on a vertical sewer riser, which often has access to the attic. In order for the sewer aerator to work properly, it needs a steady supply of fresh air.
Installation of the aerator is carried out on the washbasin, sink and bath. The installation process itself is not as complicated as it might seem. It is very important that the water supply is shut off before starting the installation. Then you will need to cut off part of the pipe and install an aerator in this place.
There are many models of sewer aerators. Definitely, each system needs its own device, but no matter which model is chosen, you can be sure that it is of high quality.
The fact is that all existing models of the sewer aerator are made from very high quality materials.
Therefore, the valves have excellent performance characteristics.
Another advantage of the aerator is the fact that it protects the house from rodents. This is due to the fact that the material for the manufacture of aerators is so durable that even rodents cannot gnaw through it.
Aerator 100
With the advent of internal sewerage systems, the need arose to install a sewer aerator. Indeed, for normal and uninterrupted operation, it is necessary to ensure stable air exchange of sewer networks with the external environment.
According to SNiP, this function is performed by a riser, which must be brought out above the roof level with a height of at least 500 mm. In this case, the distance from the riser to the nearest window must be at least 5 m.
A deflector is put on the end of the riser. It is protected from dust, moisture and debris. However, in winter there is a risk of ice formation on the pipe. Therefore, the solution in this situation is to bring the pipe to the attic. But in this case, the penetration of an unpleasant odor into the room cannot be avoided.
The best solution to this problem is to install an aerator.
The mounting element will also depend on the installation method. It can be both external and internal. Also, a 110 mm air valve for sewage can be mounted on additional risers of the sewer system.
When the ventilation of the main pipe is carried out by bringing it to the roof and no negative effects are observed, it is possible to install a vacuum valve 110 for sewage to additional risers.
In general, the 110 mm sewer valve has a number of advantages.
Advantages: 
- Pipe savings. Since it is not necessary to bring the vertical pipe through the roof slab, the footage of the pipeline will be significantly less.
- Pressure stabilization. It is noteworthy that the ventilation valve for the sewer does not depend on electricity. It performs its work with the help of air currents.
- Availability. Affordable price for a vacuum valve 110 for sewage attracts the interest of consumers.
- Ease of installation work.
The average price for a 110 mm air valve for sewerage is 335 rubles.
By the way, you can install the aerator not only on a vertical pipe, but also on a horizontal one.
Sewer aerator 50
In order to perform automatic depressurization, a sewage air valve 50 is installed in the pipe, which performs this function.
When installing a 50 mm aerator, the following conditions must be observed: 
- It is necessary to connect the sewer vacuum valve 50 to the pipe that has the smallest diameter.
- A 50 mm aerator should be installed only after absolutely all plumbing fixtures are connected.
- The installation of the vacuum valve is carried out at the highest point of the pipeline in relation to other connected devices.
But it should be noted that, according to, it is possible to install vacuum valves for systems with several risers, provided that at least one of them is brought to the roof.
Fan valve 50
According to SNiP, the construction of a one-story house may not include the design of a fan pipe. However, sometimes there is a desire to install a fan pipe even in a one-story house.
As practice shows, a sewer valve with a diameter of 110 mm is used when installing a toilet bowl to a sewer system. Also, the 50 mm drain valve for sewage is suitable for installation in the bathroom.
By the way, the valve on the sewer pipe can be installed inside the pipe and outside. It is also worth taking into account that when installing a check valve, it is not recommended to use any type of lubricant, even if they are intended for sewer systems.
In general, we can conclude that the aerator protects the living space from the penetration of unpleasant odors into it. The aerator guarantees the normal operation of the sewer system and increases the level of comfort in your home.
