I have a Pentair Challenger 1 horse pump that is starting to make a noticeably louder humming noise
while running.Im in Charlotte NC and run the filter whenever it goes below freezing and have been doing
so for the last 5 years.This will be the 6th season coming up and I think I'm just gonna replace the whole
pump assembly.My question is should I upgrade to a 1.5 horse pump if there isnt a big price difference?
My pool is a 20,000 gallon inground SWG vinyl liner pool.Thanks
