"Dave, I can't do that" fired this volley in
:

It is pretty common for the water to wear a hole in the lowest pipe
about 10" above the pump connection. When the pumps shuts off, this
then drains down the water head so the pump needs to run again.

Dave, the first thing (not electrical, sorry) that comes to mind is to
deal differently with what must be a LOT of sand in your water!

Just replacing the bottom 10' of the lift pipe with something more
abrasion-resistant would seem to be a good thing.

I personally don't have a submersible, anymore. 'Had one at my last
house, but now, although our well is 180' deep, the water table is within
10' of the surface, so we use a common above-ground jet pump.

But when I had a submersible, it lasted 23 years in regular residential
service (until we move...), along with some irrigation. We had limestone
formations, not sand.

I'm sure someone else has had this problem, and the well/pump industry
likely has a solution to it. (dunno... something like a 'droppable' HDPE
liner, or something, so it can be serviced without pulling the whole pipe
string). If the HDPE were the full length of the string, it could
probably be replaced by the homeowner at less cost that hiring it out.
