Good morning, Cary. Hope you're well.
A few weeks ago you helped to answer my questions under another post with the same subject line. Got it working finally with your assistance. Thanks!
I have a new problem. After the install, one of the pvc screw connectors failed, spewing water. Unfortunately, we didn't become aware of the failure until a couple of days later. I fixed the broken connector, but when I switched the pump on, it froze up and began smoking. I replaced it with a new pump, and it's pumping great. At a flow rate of 3 GPM, the pressure needle hovers at 20 psi.
When I shut of the flow, the pressure builds up to 40 psi. However, it does not build up pressure beyond 40 psi, and the pump continues to run. Pressure stays at 40 psi, so it can't reach the cut out at 60 psi.
Believing there must have been an air leak on the suction side, I tested all visible connection points with foam (shaving cream), but couldn't find any air leaks. So I decided to dismantle the system on the suction side from the foot valve to the pump intake, making sure that every pvc pipe had clean, straight ends, and the couplings, elbows, etc. were well-soldered and tight.
With all new plumbing installed, I switched the pump on, but I'm getting the same results. I figure it's got to be something else. Even the pressure switch was replaced!
Any thoughts, please?
