SOURCE: Hi, I have a Grunfos

First check with a pressure gauge to see that the pressure is, indeed, dropping. Then, if it is possible, turn off the outlet valve to isolate the pump.
If pressure is still dropping, there is probably a check valve on the inlet of the pump that prevents water from the high pressure side from leaking back to the inlet piping side.
To test this, let the pump run and pressurize the house and immediately close the valve for the incoming water. If the pressure holds, then open the inlet valve and see if the pressure drops. If it drops, the inlet check valve has to be replaced (or cleaned).

Sounds like it may be air in the system - there is a black plastic bleeder screw on the top of the pump - open it and let air escape, if any, then fill with water, close screw and start pump.

With the water running the MQ pump runs intermittently


This is a problem with your bladder in the pressure tank or the pressure switch. Ether one will produce this cycling on and off. Good luck.
