Our well is 155' deep, 1-1/2 hp submersiple pump. I can hear the pump running but little or no pressure is building up in the system. Ran all night and still did not get up to 60 lbs and shut off. The way I figure is: 1. My well is going dry. 2. My pump seal is bad. 3. There is a blockage somewhere between the pump and the pressure tank. Anyone have any other ideas how to trouble shoot this? Can I pull this pump myself? There is a safety rope sticking out of the top of the well head, I think the pipe is PVC. I do not have a tractor or other large equipment. Thanks in advance!
