Question:

Water meter check valve, front and rear should be installed according to it?

Water meter check valve, front and rear should be installed according to it?

Answer:

A check valve is installed after the water meter, so that the situation can be avoided.
Generally installed after the water meter.The main reason: if the water point is higher than the water meter installation position, once the pipe network in the absence of water, the remaining water in the pipeline will flow in the direction of the water meter in turn. This will cause the water meter to reverse and cause damage to the water meter.
According to the specification, the backflow meter shall be installed in front of the municipal water meter, but some of the city's single water inlet only needs to be equipped with check valves.Floor residents do not need to install check valves for small water meters.
