My pool is about 32 feet in length and 17 feet in width and holds approx. 26000 gal. I have a Hayward Power-Flo LX sp1580z2 pump. When I went to turn the pump on for the first time this year it just made a humming noise and nothing else. I started reading on what the issues could be and found on a site that this pump is for above ground pools. So if this is true should I just replace the pump with a larger one or try to fix this one. If I should change to a new pump what should I get? Thanks in advance for any help.
