I had the same problem and the solutions worked for awhile. Now, every time I turn on a tap, the pressure drops and I have to re prime the pump. Right now I have a magic marker wedged in to keep the lever from moving too much, so that I don't lose all water pressure. Will that hurt my system and what should I do?

Help me, please.

The first thing I'd be checking is the check/foot valve to see why you're not holding prime.
Have you checked the bladder/pressure tank to see if it's charged? )A b ladder tank is charged with 2 PSI less then the cut in pressure on the control box.) And tell me why you have anything wedged in the control box? Back to you, Tom
