Maybe equally as important is performance. I also have a conventional 1/2 HP
120 vac Sta-rite submersible supplying our water for 21 years with no issues.
It certainly has it's surge at start however the 2, OBFX3524's (120 vac only)
running it seems to have dealt with it for many years.
Water elevation during pumping is at 110 feet and then pumped 83' feet
vertical to open discharge storage tank. So at 193' of head, I'm getting 5.2
gal/min. It would be great to know how the grundfos compares...in real life,
not from a chart.

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.
