Hi guys: what a great site! Thanks to all you who contribute your time and expertise. My 2Hp Hayward MaxFlo pump has died. After consultation here I have learned that the 2 Hp's were way too much for my Hayward S244T Sand Filter. So with 30-cent/Kwh electricity I'm looking to replace that motor w/a 1Hp motor, keeping the 56J pump. However, would dropping from a 2 Hp to a 1 Hp motor require any change in the pump impeller? and if so, what would that involve; how hard is that to change, if at all possible?
Thanks in advance for any input you may provide.
