Here is a brief and concise history (hopefully) of my cistern and pumps. Cistern holds approx. 1500 gal. Water ht. in cistern- 42 in. Elevation from cistern to house approx. 100 ft. Length of 1 1/4" pipe- 1000 ft.
1st pump - Sta-rite 3/4 hp, 2 wire, mounted horizontal, pumped great from 1980 to 2010. All the household water for 3 people ( 365 days/yr) plus pumped countless thousands of gallons for cattle watering trough.
2nd pump - Myers "Rustler" 3/4 hp , 2 wire,cat. # 2NFL72-12-P4 with a Pentek motor. Failed this year after only having to pump water for the house approx. 20 days/year (house now used by daughter as 2nd home). This pump was installed vertically in cistern. A hole was created in concrete bottom of cistern with pump inlet about 4" above bottom. This was done because retailer couldn't assure me that pump was rated for horizontal application.
At this point I have not disassembled pump to try and determine the cause of failure. The last time pump ran it was making horrible screeching noise for about 20 seconds before shutting down.
I would like recommendations for a new pump as I am concerned about premature failure occurring again. The details about the vertical mounting were included because after reading many posts about submersible pumps I became aware of cooling problems. The setup I have with the motor mounted in the concrete floor shouldn't have caused a problem, correct ?? I mean temp of water and concrete probably never gets above 55.
Any thoughts would be greatly appreciated.
