Is a Variable Speed Pump Worth the Investment
I live in Sonoma, CA. I have a small in-ground pool in my backyard. It is 12' x 20' with a six foot deep end and about 3' shallow. I estimate it to be about 10,000g. The pool was built in 1978 and I had it re-plastered about three years ago. I would like to replace the original equipment pump this spring. I have an 8 year old Sta-rite cartridge filter. I am wondering if a variable speed pump is worth the extra expense? I have no heater or solar so I don't anticipate I need much more than 3/4 hp if I go with a single speed pump. We swim from about April to September. I cover the pool and shut everything down during the off season to save energy. I run a Polaris 360 Vac off the main water outlet from the pump so possibly looking at 1 hp. I'm having a tough time swallowing the $800-$1000 cost of a V.S. Pump, while I can get a Quiet Flo Plus 1hp for around $300. Any suggestions are welcome!
