How to prevent the sewer  reversing the water  install the anti-reverse check valve steps on the 2nd floor

Introduction: Generally, the sewers reverse water,  the second floor suffers. It is necessary to install anti-reflection check valves. After the first floor is changed to an independent sewer, the second floor  the floors above share a sewer pipe. The second floor is equivalent to the first floor below. The water  all floors goes to the second floor. The pressure of the pipeline is high. If the pipeline is  dredged frequently, it will cause the pipeline to block  reverse the water. Therefore, it is necessary to install the check valve. Let me tell you about the installation steps of the check valve.

Tools/Materials:

1. Bonnet rotatable check valve set

2. Saw

Steps/Methods:

1. Check valve principle The check valve opening  closing parts are opened  closed by themselves by the flow  force of the medium to prevent the backflow of the medium. The valve is called a check valve. The check valve belongs to the automatic valve category, which is mainly used on the pipeline  the medium flows in one direction,  only allows the medium to flow in one direction to prevent accidents. Therefore, it is also called a one-way valve  a check valve. The reverse water valve of the pipeline is automatically closed to play a non-return effect, thereby solving the problem of reverse water in the sewer.

2. Reserve installation space: The total length of the double insurance suit is 50 cm,  50-55 of installation space should be reserved. If there is a trap, the trap should be sawed off  installed. The trap has drawbacks.

(1) If there is a trap, the water will become slower  affect the drainage.

(2) There will be things like vegetable stalks in the water trap. If the water is reversed, the dirty things will jam the valve plate  affect the use of the check valve. If the valve is too long, a section should be cut off, leaving enough connection at the end. A check valve kit will do.

4. After splicing the check valve, take it to the sewer  compare it. The check valve should be installed horizontally  horizontally. The sewer pipe that comes out of the pipe should be sawed off. It is necessary to change the level of the elbow to install the check valve, the outer diameter of the pipe is 50,  the inner diameter of the ball valve is 50.

5. After checking that there is no problem in the installation space, you can apply glue  glue the accessories. After the glue is applied, the accessories should be glued immediately. The PVC water supply glue dries faster. If you stick it wrong, you need to replace the accessories. If the Hammond check valve set is installed at a distance  the cabinet below, you should put something under it to support the check valve set.
