A two-component question:
I presently have a 20yr old 1/2hp Purex WhisperFlo that has just started to leak. I'm considering replacement with either a Pentair VS or hi-eff two-speed pump. My (winter) ELX cost is $0.12/kWh ($0.18/kWh in summer). I have an 80 sf cartridge filter and a solar heater at approx 9 ft above the pump. All 2in piping and 220V. With everything clean I get 7 psi (no solar) and 14 psi (w/solar). I have one skimmer and three returns in a 10Kgal pool w/no features and a 2wh Jacuzzi Tracker.
Regarding the pump, the local utility has a $120 rebate on VS pumps, but requires a contractor install. The locals will happily consume the rebate and are still high IMHO. The expensive-to-repair VS also has the limited DIY warranty; all of the above and the small pool incline me to a two-speed pump but I could be persuaded o'wise. Any automation I may use would likely be happy w/ just two speeds. Online, at $634 for a 011486 two-speed vs $880 for the 011018 VS, their price difference is small-ish to me. Even including the rebate, I would still be approx. $400-600 cheaper as DIY vs. contractor for the VS pump.
Is there a two-speed pump that allows the optimum speeds to be manually selected with jumpers?
Regarding the filter, I was looking at the Quad DE 150 (for long cleaning intervals), and was mainly curious what drives the bewildering choice of rotary vs slide valves. I have a convenient backwash drain. I have time until the filter R/R.
