I've read several other posts, but didn't see any that matched my situation exactly.
I have a 3/4 hp deep well jet pump that has had several recent episodes of running continuously. At first, I was able to adjust to pressure switch to get it to shut off, and I eventually replaced the switch, thinking that the contacts were worn. The new switch seemed to work for a few weeks, but the continuous running problem has returned.
This time, the pump can't seem to build any pressure, which wasn't the case previously. I adjusted the switch again, but the pump now shuts off at 35-40 psi, and has trouble building even that much pressure. This is just a temporary fix until I can find the real problem. I can still pump water to the house.
I can shut the distribution valves off and the problem is the same, so it isn't a leak. I replaced the foot valve a couple of years ago when I replaced the pipe in the well and the pump holds its prime, so I don't think that's the issue, but I can't eliminate this possibility completely. I also haven't checked the bladder pressure in the tank, so I'll do that tomorrow.
I suspect that the pump, which is about 10 years old, may be wearing out, which would help explain why the problem has gotten gradually worse over time rather than the sudden and complete failure of a component. I am ready to purchase another pump, but wanted to see if I was missing anything before going to this expense.
Any ideas or suggestions would be greatly appreciated...Thanks!
