[RE-wrenches] Off-grid deep well pumps

[toddcory at finestplanet.com]

i would also like to hear service reports on this too, specifically the standard grundfos centrifugal pumps with dc motor (SQF). helical rotors wear faster, so of course their life would not be as long.

by comparison, i have a 26 year old, 3/4 hp standard well pump which is still fully operational and in irrigation season, pumps ~2500 gallons a day.
