For the second time this season, my Hayward 1.5 HP SuperPump is tripping the GFCI breaker. It's in the motor shop now (as it was back in May - to the tune of $180) to be fixed up if possible.
It's been a rough year -- I had to buy a new cell for the AquaRite this year too... This pump was NEW in the spring of 2012. Seals were leaking after I installed it when I opened the pool (I bring it into the garage for the winter). Installed a new seal kit and took care of the leak. Then it started tripping the breaker. Got it fixed. And here I am. Again.
My setup is a fiberglass in-ground, 12K gallons, 200 lb sand filter, gas heater, AquaRite SWG. I have one skimmer and one main drain which T into a jandy valve about 12" from where the pump sits. Three returns are plumbed in series. All plumbing is 1.5" PVC. Clean filter pressure is around 19 psi. I have a simple timer to run the system 16 hours a day, and all electrical is 220v.
I acknowledge that 1.5 hp single speed is probably too much pump for my setup. The pool was built with a 1 hp SuperPump, but when that failed suddenly a couple years ago, I hurriedly replaced it with what I could find locally. I've had it with these SuperPumps.
I'm considering going with a 2 speed, or even a variable, but I know my bride will balk at the cost. I explain to her that one who owns a pool cannot quibble when things get expensive... because pools can do that in a hurry.
So... I have no idea what to look for in a 2 speed or variable speed pump. I know Pentair is highly regarded on these forums, but what other viable options are there? Most importantly, what should I absolutely NOT buy?
Thanks for your input.
