I have a rather old well system although I had to replace my compressor and the pump that brings water up into the cistern/holding tank as well as replace my actual water pump twice. The lever on top of my holding tank keeps sticking so that even when the float is all the way up, it does not trigger the compressor with the pulley wheels to shut off. When the tank is full it continues to run so I have to go outside (sometimes in the middle of the night with a flashlight), go through several gates, and then reach in and tap the metal lever (attached to the electric lines) up and it shuts off. But before I realized this was a problem, I didn't go and do that. First the edge of one of the pulley wheels sheered off and I had it replaced, but then the motor died and I had to get a new one. Then, because the compressor was broken and the pump was trying to pump an empty tank, the motor burned out on the jet pump. I was without water for 3 weeks because my old pump guy seems to have developed Alzheimers and forgot to come out, despite the fact that I called him repeatedly. I finally found a new guy but by the time he came out it was a weekend and I ended up getting a crappy Countryline brand pump. Stupid thing cracked a rod in a piston within 2 months and I had to replace it with another brand. I'll have to try to remember which one-- it was the pump I had before that lasted over 15 years. I think it is something like Lenovo... I told the new pump guy about the lever sticking and he suggested putting vaseline on the metal rod attached to the float to see if it was just sticking. That didn't work and it seems like the problem is the part attached to the wires-- which I do not want to touch. Now another problem has arisen where my jet pump just stops working and I accidentally discovered that when I pulled up on the electric lines going to it, it flashed lights and started running again. It would stop and I would pull up and it would kick on again. I don't know if the wires or loose or if it is depressing a button or what the deal is. I don't know if I should just tape the wire so that it keeps exerting the same amount of pressure or if I should call the pump guy to check the wires. When I replace the batteries in my digital camera I can take pictures if necessary. I've also noticed the floor in the pump house is often damp, but I don't know if it is because of humidity or because my cow tore a hole in the corner of the structure and rain gets in. I live in a very humid climate. I didn't see any signs of leaks anywhere. Could the moisture be affecting the power to the jet pump? I really don't know much about pumps so these are probably dumbo questions.
