Re: submersible pump goes on and off
Is the pressure switch cycling (can you see what the contacts are doing?), or do you just hear that the pump is starting and stopping?
If the pressure switch stays "on" but the pump appears to be cycling, then there could be a problem either with the motor or the starting capacitor circuit (usually a gray box between the pressure switch and the wellhead).
If there's a failure of the pump motor, it could manifest itself this way: starting capacitor kicks in and makes the motor turn; when motor reaches speed the capacitor kicks out (as it's supposed to). Since the running winding of the motor is bad, it can't keep the motor turning. A few seconds later, because the motor isn't turning, the capacitor kicks in again and makes it go for a few seconds more.
That is just a wild guess based on a rudimentary understanding of how pump motors work. I'm no expert, but I can conceive that it *could* be the problem.
