What is a check valve for sewage
Sewerage is an open system,so the fecal masses can go in the opposite direction when the pipes are clogged. To avoid such trouble, you should install a check valve for the sewer.
Varieties of check valves and their installation locations
The valve can be installed in two ways:
1. Installation of one common non-return valve, the throughput of which is very high.
2. A non-return valve is installed on each element of the plumbing.
A common valve should be installed only in thoserooms, the area of which is not large. In addition, the installation of valves by this method depends on the location and design of the sewage system itself. A common valve for sewage is installed very rarely. Installation in the second way is more often used, since in this case the area of the house and the location of the sewage system do not play a special role.
A non-return valve for sewage has twovarieties: common and for toilets. The second kind is also called a check valve for the pipe pipes. Such valves are mounted directly into the pipe. Especially it is necessary to approach the installation of check valves for toilet bowls, if there are pipe counterparts, and it is not possible to correct this situation. Valves are mainly made of metal or PVC. Previously, flanged metal valves were used, but every year their use becomes less frequent. This is due to their fragility.
Check valves for sewage and their dignity
You should be aware that the check valve for water andThe valve for the pipe pipes has a different design and a different operating principle. The first valve has several different levels in the nozzles. In the space between several nozzles a ball is placed, filled with air. If water flows through the pipes in the opposite direction, then this ball closes the inlet pipe by pressing on a special membrane. Such valves can easily be cleaned, since they have a removable cover. In addition, they can be blocked in the event of a mash with a special valve.
For valves, valves are installeddirectly into the pipe itself. In diameter, this valve reaches eleven centimeters. Usually a check valve for sewerage goes on sale in the form of a cylinder with a lid, which opens under the pressure (head) of water. After the water has been released, the lid returns to its original position using a spring mechanism. The lid opens only one way. In other words, if the faecal masses go in the opposite direction, they can not open the lid.
Even in those homes where the system is working properly,it is necessary to install a non-return valve for the sewer, since it not only delays the flow of fecal matter, which can change its original direction, but also prevents the appearance of unpleasant odors from the pipes of the sewage system.
