    Going to two speed pump, request help on size.

    I have an AGP with 8500-9500 gallons. Currently using Hayward 1.5 HP single speed pump. I'm replacing it with a two speed to save on CA electricity. I think I should get my money back quickly here.

    I'm looking at Hayward SP15922S Power-Flo Matrix Above-Ground Pump 2-Speed. It will match my pad and filter with no issues since it's the same series. From reading there I believe a 1 HP on low will be plenty fine for my pool but would like to check before shelling out $300. Use 1 1/2" flex and rigid PVC, pump approx. 20' to return/skimmer.

    That is a good choice. I would recommend a 3/4 HP two speed, but they are very difficult to find.

    Thanks for the quick reply! Couple weeks and it should be warm enough to jump in here.
