I need to replace my pool pump as the bearing are gone and I am leary of previous cavitation trouble. I have been to three different pool stores and have been given three different recommendations. Now I want the real answer, not just what they are trying to sell me.
Specs:
20,000 gal pool Pool/Spa combo with 4 spa jets 2" PVC supply lines 2" PVC return lines Pump - currently a Pentair Whisperflo 1HP Full-rated 115/208-230 volt (original equip from 1986) Filter - Jandy CL460 Cartridge Heater - Raypak RP2100 Natural Gas Cleaner - Suction side Kreepy Krauler type Equipment is located about 40 feet from the skimmer Need to have a pump that is as quiet as possible as it is located right under a window of our house.Advice so far:
- Replace only pump MOTOR and seal with same exact single speed 1 HP Whisperflo motor. (Was told least expensive and all that needed to be done)
- Replace entire pump with single speed 3/4 HP Full-rated Pentair Whisperflo. (Was told the larger pump size causes cavitation and is louder, and that 3/4 is plenty strong enough for spa jets)
- Replace entire pump with 1.5 HP Full-rated Pentair Whisperflo. (Was told needed larger pump to match large filter size and decrease circulation time)
- Replace entire pump with 1 HP dual speed Pentair Whisperflo. (Was told it is the quietest ,most energy efficient, but more likely to malfunction early and much more expensive)
Questions:
- Is filter oversized? It is brand new, put in by the pool company that replastered.
- Which option above is best for this pool? Or other option even better?
Thanks!
