Why do water flow indicators often alarm?

Dear, in view of the situation you said, Xiao Bian believes that the water supply side pressure should rise, directly from the water supply side water pressure fluctuations, and the wet alarm valve is essentially a check valve, only water is allowed. Flow in one direction. When the system side is at a certain low pressure, the wet alarm valve is in the closed state, then the water pressure on the water supply side rises, and the wet alarm valve opens, causing a false alarm. The method is: using a steady-state pump to stabilize the voltage, if the steady-state pump fills the level slowly, the valve flap is always opened at a small angle to replenish the pipe network, that is, no "false positives" will occur. Therefore, it is recommended that you pay attention to the water pressure not too high when you use it in the future!
