I have an inground pool, 16,000 gallons, Pentair Whisper Flow pump. model WFE-6, 1 1/2 HP. About 4 years old. It is getting louder every week. The drive end motor bearing is going south. I had the motor off and checked the bearings. The drive end bearing has some looseness in it. I can probably just replace the bearings in the motor, but could I upsize from my 1 1/2 HP motor to a 2 HP with out causing any problems?
I had a solar heater installed this summer. The Solar guy said my 1 1/2 HP will do it, but a 2 HP would be better. It is using 2" piping up to the roof, (single story, on the garage roof, maybe 75' of pipe up to the roof and 75' back) 2" piping at the pump but gets smaller after the in floor unit.
Can I up size to a bigger motor, or even should I? I have found AO Smith 2 HP motors rated at full rate (B748), and up-rate (B855). What is the difference?
