I think my existing 6-7 year old Hayward super pump 2 died on me this weekend. It tries to start making a noise, and actually makes the water in the basket move around, but stops after a second or so. After 10-20 seconds it tries again. I took the wet end off the pump and tried turning it on without the wet end connected and it fired up no problem. I connected it back up to the wet end and get the same failure as before. I was all set to get a new pump as I couldn't figure out what's wrong, and figured I would sacrifice some pool down time to see what folks on here say.
I believe I need the 1.5 HP since I am using it to power a Kreepy Krauly Legend II without a booster pump, however we seem to be needing to replace our filter cartridges every couple of years, and I wonder if its because the pump is too much for the pool.
I am looking at replacing it with either the Hayward Super Variable Speed pump, or the Hayward TriStar High Performance 2 speed pump. Any recommendations or thoughts on the pumps, or things to try with the existing one?
