I think you'll love the 2 speed 1 hp SuperPump--I do. I have a skimmer and low drain, a return and a solar deck, about 20,000 gals. All 1.5" piping. I run on low all the time with no problem--be sure to have at least a 200# sand filter--the Hayward t210 is a good match.

Just flip to full speed to backwash or vacuum.

It will take almost twice as long to turn over your water as it does at high speed--and will cost 1/3 as much per turnover. Also low is SO quiet you can barely hear it.
