During the construction of a country house, it is important to correctly install the pipeline and configure it. If the house is in height of more than one floor — work with laying and setting up the pipeline is significantly complicated.
Sewerage in a country house should not create annoying squishy sounds, should not let unpleasant odors into residential premises. There is an air valve to fulfill these duties. This device helps prevent sounds and smells from sewer pipes.
The principle of operation of the air valve
In the building with more than one floor, ventilation must be present in the sewage system. Most often, an air valve is used to perform ventilation work, built into the pipeline system. During any drain of water into the sewer, the air discharge process appears in the pipe, which entails the creation of unpleasant noise. The air valve serves to align the pressure in the sewer pipe by pumping the missing amount of air into it. The valve’s work is absolutely silent and does not create additional discomfort when using a toilet or bathroom.
What does the valve consist of
The air valve, due to its simple design, is very easily installed in the sewage system. The basis is the case made of polyethylene. A special hole is located on the side of the case, which serves for air circulation. Rod, which, if the difference in pressure occurs, opens a hole in the housing. On the rod there is a gasket made of rubber, which serves to limit movement and create smoothness.
Types of valves
Air valves are conditionally divided into two types. Anti -Wacuum and automatic. The first is used in large and complex sewer systems. Knows how to let air into the pipes and let it out of the sewer. Automatic air valve is most often used in private residential buildings. It is used only to remove excess air from sewage pipes. There is also a combined variant of the valve that has incorporated all the advantages of the previous valves.
Calp installation
The installation of a sewer air valve is similar to the installation of almost any fitting for pipes. The installation place is selected depending on the alleged effect. The valve can be installed both for servicing the entire pipeline system in the building, and for servicing a separate unit. In the case of the first option, the valve is installed in the attic.
