Can I get some help (i.e., recommendation(s)) on pump replacement?
We have an inground pool (about 32,00-35000 gal) that may be 40-50 yrs old. Recoating starting today (yay!) I have read the Hydraulic 101/Pump Basics postings and appreciate that information but there is still a lot I don't quite understand. The original pump when we bought the house (and pool) seven years ago was 1.5 HP with SF of 1.47 = 2.2 SFHP (220 V). When it went out a little more than a year ago, I replaced it with a 1.5 HP with SF of 1 = 1.5 SFHP (should have read TFP Pump Basics then)...must admit budgetary constraints at the time influenced me...). ~Weak pump that would not pump effectively when filter pressure went up at all. Filter - DE6000 (DE, 60 sq ft, 120 gpm design flow rate). I don't know much about the piping below the concrete. A basic guess is that there is about 207 ft of piping on the supply side and 193 ft on the return side. Max depth is 9 ft. Rough calculation is 97 ft of head...? My question, of course, is - what pump should I buy to replace the cheap pump? I am thinking about SFHP=2, two speed seems most economical to operate...any suggestion?
We have a lot of trees around and end up with a fair bit of organic material (leaves, pollen, catkins, etc.) that requires more attention but will also competes for chlorine in the pool. I do mainly use the BBB approach plus some tablets to supplement (mainly when I travel).
Thanks for the input!
