The water meter doesn't move. The pump keeps beating. Why?
If it is a pump problem, check the following items:1) if the pump outlet pipe has a pressure gauge, or suction pipe mouth has a vacuum meter, calculate the sum of the two, whether or not close to the head.2) observe the pump housing bearing whether there is a large number of leaks, if there is, please check the leakage ring and other sealing devices3) check the pump blade whether there is excessive damage, such as cavitation4) check whether the blade is correct or not5) check the pump mounting height, the height is greater than the allowable suction height (centrifugal pump, 5~7, m) if it is self Jiezhuang pipeline pump should pay special attention to this problem, the height is not more than 2~3 residential floor height. For example, the third floor does not need to install the pump, may have the water, then the pump installs the highest not to be able to exceed six.6) check that the suction port is blocked7) check the suction pipe whether there is greater hydraulic loss
Is the meter impeller stuck, meter replacement or repair advice. If the water meter is connected to the water outlet, the pump draws water and the user doesn't use it, the water meter doesn't go, because the water meter doesn't flow through.)
First, check the pump connection pipe whether there is a valve open, if there is no flow out, the water meter is not going.Second, if there is water flowing out of the pipe and the water meter doesn't go, it's probably the water meter is broken.Third, check the flow of water outflow, if large enough, it can be sure that the water meter is broken.Fourth, if the outflow of water less than the meter (don't know your water meter specifications) the starting flow, it should check the pump.
