    Pump pressure switch does not shut off
    I just replaced the pressure switch on my pump. It's a deep well pump with a 20/40 switch. The switch does not shut the pump off when it reaches the forty psi level. In fact, the only way that we can turn the pump on or off is by unhooking the electrical connection.

    Did u let the pump run above 40 PSI?

    If not let it run to 60PSI.

    When u replaced the switch, did u wire it the same as old switch? Are wires on the same terminals?
