    We just recently bought a house with a well and started having issues. The submersible pump is ALWAYS running but the water pressure only gets to 18.

    I did follow the instructions on the sticky and replace the pressure switch as well as the gauge. The problem still exists. We have the pressure tank and the water filter left to tinker with, but I wanted to ask advice before I start switching things out.

    What are some possible causes for constant pump running and very low pressure?

    Thank you!!!!

    It's not the filter.

    I expect it is one of these:
    1. pump is bad.
    2. the well is running dry. Test for that by turning off the pump for a few hours. See if pressure is a lot higher when you first turn the pump back on.
    3. there is a leak in the connection to the pump, which may be down-hole.
    4. Something is draining a lot of water up top. Close valves to isolate. (least likely, since you would probably have noticed)

    Look for obvious stuff, but expect to call a well company. Ask your neighbors for advice. They will probably know the local reputations.

    non-expert, non-pro.

    My vote is for a hole/leak in the drop pipe going down into the well.

    Definitely sounds like a bad leak.. Go back and look through your electric bills, I bet they were higher than usual.

    Do you notice any wet spots in your yard? The leak is either from your house, to the well. OR from the pitless down to the pump. If your pump is on poly pipe then I would guess the leak would be from the well to the house (9 time out of 10 its the fitting off the pitless)

    If it isnt a leak, then the impellers on the pump are shot, and you should replace the pump.

    EDIT: I just saw that you posted your pump is on galvanized steel pipe. I would say the pipe is leaking on the couplings. Very dangerous on gal, ive lost pumps from couplings becoming so weak. Call in a professional, your going to need a derrick truck or an upzdazy machine at the very lest.
