Last summer my ancient 2 HP AO Smith Centurian pump started making a very, very loud noise, and our power meter started spinning at hyper speed! Our electrical costs soured by over 2x. A process of elimination (plus the obvious deafening noise) indicates to us that we need a new pump. The pump did survive the season, but each time I cleaned the pump basket I feared (or hoped!) it would not start.
From reading this forum, it seems 2 speed pumps are usually recommended. We have relatively cheap power, and I don't know how how many more years we'll be living here. Point being, I suspect that VS pumps are unreasonable for me.
What 2 speed pump would you recommend to replace our Centurian pump?? I have a 30K gallon IG vinyl pool, no extra stuff like waterfall or solar, and I have 2 strainers and 3 returns. Pump and filter are 20 feet from pool, and located about 2 feet above water level. I have a System 3 S7M120 filter.
I'm looking to save as much money in operation and initial investment. Thank you in advance!
