I just recently purchased a foreclosure house to fix up and sell. The first thing I did after purchasing it was kick the water pump on to see if it worked. The well is right out in front of the garage and is a deep well with a submersible pump. The utility room is boxed off very small and has the water heater and furnace in it and the pressure gauge and switch are tied in right before the plumbing goes throughout the rest of the house. I have looked everywhere and can't find the pressure tank. I believe it may be buried, but am really hoping I'm wrong. I noticed that the pressure builds up to 25 psi and can't get past it, but also noticed that the pump never shuts off. My father stated that if the tank isn't in the ground it has to be close to the switch or you can get some kind of jumping in the lines. Not sure exactly what he meant by that, but he is an old school retired plumber that knows quite a bit about plumbing, but I don't think he knows to much about wells and pressure tanks.The house was built in 1971 if that helps. I originally turned on the water 3 weeks ago and haven't turned it off. I don't live in the house, but everytime I check the pressure is always at 25 psi and I can hear or I guess feel the line and can tell the pump is on. The pressure does go down when I turn on a faucet and seems to take forever to get back to 25 psi before it stops at that, but the pump keeps pumping. My father said the pump must be shutting of at some point or the pump would have burnt up over the last 3 weeks of continuously running. He believes the bladder may have busted in the tank. If so can I simply install another pressure tank before the plumbing gets to the pressure switch or will I have to dig up and replace. Could it possibly just be a bad switch. I haven't turned the main screw yet on the switch to see if that helps anything. So my guess is either bad bladder, bad pressure switch, or I hope to god not a leak in the line somewhere underground before it gets to the pressure switch. Also not sure if this means anything, but the piping is copper 3/4 in and piping where it comes through the garage into the utlity room the pipe does a weird U-shaped thing before it ties into the pressure switch.Any help or thoughts would greatly be appreciated. Thanks!
