My 5 year old single speed 1.5hp Hayward Super Pump is on it's way out. The pump choices out there make my head spin. I have been looking at variable speed pumps. The Ecostar is one I keep going back to since all of my pool equipment is Hayward (like that matters) but there seem to be a few issues with bubbles/cavitation at lower speeds. I know the Pentairs have good reputations as well. Any opinions?
I currently run this energy hog Super Pump 24/7 but we have reasonable electric rates around here at .15/kwh. Pool has 1.5" plumbing. Looking for some recommendations before this thing kicks the bucket. Thanks!
