i just installed a new pump in my well and it came on once and pumped up to 50 psi but when the pressure dropped to below 30psi the pump came on and only ran for about 5 seconds and shut off if i turn the power off for about 2 minutes it will run for 5 seconds and then shut off again not pushing any water at all

With the power off, I would inspect the controller to make sure that it is rated for the size pump that you have, as well as the pressure switch, including the diaghram and points for signs of physical damage or wear.

the pump i use doesn't require a controller. installed a new pressure switch and new pressure tank as well.... could the amp draw on the wire be causing this

Have you determined that the pump that came out of the well is exactly the same as the one put in?


How old was the pump that was pulled out?

What's the elevation from the well to the house?

What HP pump do you have down there?

I would think if the pump sucked up a rock and it jammed the impeller it would act as you describe if it had a thermal switch. The motor would try to run but since it cant turn it overheats and turns off. The two minutes you have the power off is enough for the overload to re set and the same thing happens again, just an idea.

it done the same thing with two pumps i wonder what the odds are that it picked up a rock

I think it is unlikely that they both got a rock. When you replaced the pump did you replace the cable going idown the well? if it was damaged I would think it could cause a voltage drop that would prevent the pump from working correctly. Another idea is that the new pump dose need a controller, also if the contacts in the pressure switch are dirty that could cause it to not work.
