Any help troubleshooting my problem would be greatly appreciated. I have a submersible pump (about 550 feet) that was replaced about four years ago. Today we had no water coming from any faucets. I checked the well circuit breaker (it was on). I checked the expansion tank pressure gauge (reading 60 psi). I pulled the whole home water filter (no change). Very little water was coming out of filter supply side. I opened the water valve (by the expansion tank) and water came out. I didn't open it much since the water flows on the floor. Tomorrow I'll connect a hose to the valve and see how much water comes out. We just got back from a week vacation and my wife was using a lot of water but I don't think enough to drain the well. When it rains it pours my Central AC went out as well. Probably an evaporator coil leak. I'm fairly competent in repair work but mostly electrical and I have very little plumbing experience. If someone can give me an idea where to start looking I'll appreciate it.
