Well pump motor humming.

When a water pump only hums that is it s not moving water the problem could be a bad pump motor bad motor start capacitor low voltage or indeed as you speculate if the pump has lost prime perhaps due to a leaky foot valve it may also seem to be doing nothing but humming a monotone. If the well pump or control switch makes no noise at all just hums or clicks and when the water pump simply does not run these diagnostic questions may help track down and repair the trouble. If the service area of the sump pump experiences wet conditions and the motor in the sump pump hums but there is no lowering of the water level an air lock may be to blame. This article series gives diagnosis repair advice for well or water pumps controls tanks water pressure water flow water quantity.

See capacitors for hard starting motors note that some pump motor noise including an unpleasant whine or hum is perfectly normal. Worn bearings in the motor shaft can also cause screeching noises when the pump is running. Chances are it s the pool pump capacitor. The pressure tank and well pump should be wired on the same breaker so if you find a label for well or water pump that should be the power shut off for the pressure tank too.

Pump motor humming and trouble starting. Humming pump suggests the motor was burning up perhaps from over use or there could be a failed motor start capacitor. But if your pump was cycling on and off too much or as your installer says blaming you the victim over use i suspect the original installation was improper. It s possible to change worn bearings though it s far better to simply switch out an old motor with a new one.

Try turning off the pump and priming it manually. This commonly occurs if the sump dries out often with exposure of the base.
