Alright, I'm very much a novice with pools; we moved in about a year and a half ago now, and while the pool's provided plenty of fun, we've not had much issue with it.
However, the pump is getting very loud; it still moves water fine and the gauge (on the filter) reads 12 psi as usual, it's just really, really, annoyingly loud (it was loud before but not this bad) looking online I saw to check and clean the Impeller but when I did that there wasn't really anything I could see or feel gummed up in it, so on the way home from the vet's today we stopped at Pinch A Penny, and describing the issue, he said it sounded like it was starting to go. He suggested buying a new one or having them repair it, and we've all sort of decided that, given the other issues we've had with the shoddy repairs done to 'fix' this house up, we might as well invest in a new pump since we don't even know how old our current one is (our house was formerly rented out; we don't have any documentation on this pool :/)
So here is what I know about the pool:
Approximately 7000 gallons with an Average Depth around 4.25 feet.
The Pump/Motor is a Hayward SP2710X15UN, which it says online is discontinued and a 1.5 HP pump, which the research I've done so far says is WAAAY too large, and that I could be more efficient and cost effective running a smaller pump for a longer time.
The filter is a Hayward DE3600
EFA - 36 SqFt
Design Flow Rate is 72 GPM
Max Pressure is 50 PSI
DE Capacity is 4.5 lbs
As far as plumbing, I have no clue, it looks kind of jacked (I can put a picture up if necessary; there are two lines, one going in and one going out. The pool itself is inground fiberglass (I think), with two return jets at the shallow end and one halfway down on the side that's never worked, a skimmer, and a main drain at the deep end. The shallow end of the pool is about 40 feet from the pump and the deep end's about probably ten feet.
Anyways, my question is, can we downgrade from this 1.5 HP Pump to something smaller, which will let us run for more than 8 hours a day but still be easier on the wallet?
Appreciate any help, times are tight and money's scarce around here, so if we're gonna replace the pump, I figure we ought to be smart about it.
