    How to wire pressure control switch for a well pump
    Ok, I am pulling my hair out. I changed my pressure control switch(square D). Because my pump wouldn't kick back on after getting below 30#. (I have a 30-50) It was 15 years old and I have very hard water so I figure it was time. Still the same result pump cuts off at 50 but does not kick back on. I have a salt water tank system tied into my well (FYI). On the control switch 4 terminals: instruction says motor wires go to the 2 middle terminals and the Line wires to outside terminals. I have each 1 black and 1 white with ground wire (copper). Does it matter which terminal gets the black or white? Please help. I am tired of getting "buzzed" at 5:00 in the morning starting the pump.

    How are you turning the pump back on when it does not kick in at 30#? Is there a reset lever on the side of the switch that you are using?

    If the pump is running, then you must have it wired correctly. Did you check out the little pipe leading to the switch when you put on the new one? They can clog with "crud" and cause the switch to not operate
    Properly.

    I did not completely get all the pressure out when I originally removed the Control switch. I seemed to have plenty of water coming out. What do you know about thermal switches on the pump itself?

    Is your pump above ground or in the well? If it's in the well, then a thermal switch wouldn't come into play unless it runs dry.

    Please answer the first question. What are you doing to get the pump to come on when the switch is not turning it on automatically?
