I have an above ground 27', 17,500 gallon. Ther is only about 6-8 feet of head of 1.5" hose from the skimmer to the pump' then to the Hayward 150 Voyager cartridge filer, then heater, then return. The current pump is Hayward SP1520Z1EFTC, 2.0 HP, SF is SPL. I have heard this is an uprated pump?
I tend to run the pump for 12 hrs, during swimming time (10am-10pm)since I like to have the heater kick on if water temp drops below comfort level. Heater won't run if pump is not on. I considered a 2 speed pump but if I leave the pump on 24 hrs a day, heater will run at night and waste a lot of gas. So one speed seems to be what I need.
As for size, considering the above, what would the correct HP needed be? 3/4, 1 or 1 1/2?
By the way, current pump started leaking and making loud hum last year. Since I have always suspected this pump is to much HP, I figure this is a good time to get it right.
