Just to state what may already be obvious ...

I have two wells and they do that all the time because that's what
they're designed to do.

The well pumping causes a localized v-shaped 'cavitation' in the water
table such that the pump spins faster when it is no longer submerged in
water. Topside, a current-aware switch senses the lack of load, and shuts
off the pump for a specified period of time (adjustable).

After that period of time, generally fifteen minutes to an hour, the well
has recovered, and the pump turns back on.

Until it happens again. And again. And again. All day. All night.

This is how my well is designed anyway.

You did mention you understood the controls of your system so that may
not be the case ... but ... as I said ... at the risk of stating the
obvious ... I provide this information.

Good luck!

First thing I would do is determine if the pump is actually running
when it' not producing water. With a clamp-on amp meter you
can determine that. Or even with a VOM you can find out if
voltage is constantly going to the pump. That's where I would
start before talking anything apart. If the pump is running and
not producing water, then you know it has nothing to do with
the pressure switch. From the description, it could be anything
from a bad switch to a well that no longer has sufficient water.
