    Hi ,I tried everything to get a customers well pump started.I primed it with a water pump,flooded the system with a garden hose ,the pump runs nice and quiet but will not pump.Before I remove the pump could it be the check valve???What its exact purpose it relation to the pump.If it is bad will the pump not operate????? Thanks Walt<>

    Probably not the check valve. The purpose of this valve is to keep the pump from losing prime.

    You can test the well with another pump, and if it's a well point, you can try and blow water back down the point, which can sometimes clear the well-point screen, after several repetitions of forcing the water backwards and pumping forward.

    You said the pump runs quietly? Have you checked the impeller? Is it attached to the shaft or has it sheared off?

    LOL. True story. One of our district plumbers borrowed our Honda pump a few years back to pump something out. He brought it back and said it wouldn't work because it wouldn't pump the water out. He thought the impeller was bad. I had him set the thing up for me, prime it and then try to pump out a 5 gallon bucket of water. He did all this and it still wouldn't work. I let him get a little frazzled before telling him that he had the suction and output hoses switched. :laugh:
