My well has a 35 year old Berkley submersible pump and 3 large Medalist posi-pressure tanks. The entire thing is on the fritz. Middle tank lost its air, probably blown diaphram, so we have it turned off, DH added air to the other two tanks. The pump refuses to build up enough pressure to turn itself off, hovering between 20-40 pounds pressure with 60 pounds needed to shut off, so I am checking it every hour. I have water, but there are 5 families on the well. Those at the end of the line do not have water. Tomorrow morning, these guys are going to try to troubleshoot the problems. The problem with this, none of them have done this before or know what they are doing. DH admittedly knows nothing about pulling and fixing a pump. He wants me to ask you guys for advice. See, he IS a smart guy! Okay, what advice can you guys give me in the way of detailed guy instructions or links to manuals or whatever?
