    The pressure in the expansion tank should be 1-2# less than the turn-on point of the pressure switch. How much did you put in the tank? My unprofessional opinion..

    Not sure... I have a construction crew on site and the foreman offered to push air in with his compressor. I am at a loss ......don't know what to do next...

    The pressure tank controls the pressure switch that turns the pump on and off.
    With the water pressure drained down (sounds like it already is), use a tire gauge to check the pressure tank. Set it at two psi below the pump cut-on pressure by adding air with the compressor, if necessary (i.e., if the pump is set at 30-50, the pressure tank pressure should be at 28 psi).
    After setting up that long, the pump just may have lost prime IF it's a shallow well surface pump. Do you know if it is a shallow well (25' or less) or a submersible pump (down in the well)?
    I can tell you how to prime it, if it's a surface pump.

    The well is deep so it it most likely in the well....... any clue on how to prime it ?
