Ok folks.....I finally got a chance to look at the pump Sunday. I didn't dig to deep into the problem because nothing is open on Sunday where I live...so I didn't want to be stuck without water.
I checked the tank and it is probably about half full of water......I checked the line to the pressure switch and it seemed okay.
I replaced the pressure gauge and it stays at about 50 psi and jumps to around 60 when running.
I connected an air control valve (AV-100) on the tank and ran copper tubing to the pump.
As of yet I havn't completely lost water pressure but it ocassionally does get really weak. Before it would go off completely for a minute or two than kick back on. What should I try next?
