    My submersible pump is 30ft down and it quit working about 2 months ago. I have pulled it up and replaced with a new one that is basically the same, but different manufacturer. It is used to run my irrigation, and the replacement was working and then just quit in less than a day of replacement. My pump start relay switch seems to be tripped. Whenever I try to run the system in manual mode, the pump tries to kick in, draws current from the electrical box, then all I hear is a bit of a hum. Any ideas?

    Thanks

    A big hum indicates high amp draw.

    Is this a 3 wire pump or 2 wire unit?

    The hum implies that the motor is stuck and cannot rotate. Pull the pump and check it.

    What would cause the motor to get stuck? I just replaced it within 24 hours and it is brand new out of the box.

    It is a 2 wire unit. The original pump made a humming noise but it did not trip the relay switch. The new one seems to be tripping the relay switch. It is not making a big hum, but I did notice that the pump seemed to be turning off hard/louder than the old pump.

    Most of the time pumps lock up due to pumping lots of sediment or running dry. Could be a faulty pump/motor too.

    What make of pump and motor have you got?

    How much water does the well make?
