OK, Well guys ......... I need your opinion:
Based on the amount of water our well supplies AND the amount of water our sprinkler system zones were designed to output, I want to purchase a pump that is as near identical to the present one as possible.
Sears model # 390.284040
1 HP 230 VAC
1.5 inch discharge
13.5 GPM at 100 feet AND 11.9 GPM at 150 feet - 40 PSI discharge pressure
Proposed pump (if I am interpreting the booklet correctly):
Flint & Walling model 4F10A10 (Cast Iron Castings) OR 4F10S10 (Stainless Steel Castings)
1 HP 230 VAC
1.5 inch discharge ??
13.3 GPM at 100 feet AND 11.9 GPM at 160 feet - 40 PSI discharge pressure
1- I will not use a Sears pump ... heard they are no longer as good as once before. What about the Flint & Walling?
2- Is the extra price in a stainless steel casting justifiable?
3- The F&W is a 15 stage versus my present 10 stage pump. Yet the GPM appear almost identical. What does the extra 5 stages provide?
4- Does the F&W appear to be an almost identical replacement? I want our sprinkler system to continue getting the volume and pressure it was designed for AND I do NOT want to put any additional burden on the existing well.
5- And last, is it BEST to go pick the pump up yourself OR is UPS shipped a safe alternative? The nearest well company that sells this particular pump is about 70 miles up the road. Shipping would be easier, but I wanted your opinion first!
