Hi. I've been using this forum for almost a year now and am so pleased to find it. The rules have been working pretty well for me, especially when I had to deal with mustard algea. Anyway, we need to buy a new motor but I want to make sure everything matches up (we bought the house 9 months ago). Pool size is 24k gallons, hayward sand filter s244T 300lb, Pentair 1.5hp single speed pump, and SWG. I would like to get a 2 speed pump and am also wondering if we can downgrade in motor size to a 1hp. The online information to determine pump size is overwhelming me, please help
I know the skimmer pipe is 2" and the main drain pipe is 1.5". The average feet of head is about 35.
Which is best, a 1.5hp motor or 1hp?
