Long time lurker, first time poster. My 2-speed Pentair Whisperflo WFDS-24/012485 (HP 1.0/SF 1.25) died at the age of 11. It runs at low speed (very hot), but at high speed it kicks off almost immediately. I looked at rebuilding it, but it is completely rusted out, so by the time I put a new motor and impeller and seal I figured I'd be just as well off replacing it. I was pretty happy with the performance and noise level, so I thought I would just be able to buy another one, but I haven't been able to find it or the full-rate version (WFDS-3) on any reputable pool equipment sites. In fact, it appears in the 11 years since we put in the pool that 2-speed pumps are no longer in vogue. Lots of people seem to be keen on variable speed pumps, but we initially put in a 2-speed pump because it was much more cost effective (cheap) at the time and it appears that the pricing hasn't changed all that much. We have a ~35,000 gallon rectangular 22'x40' pool with 2 skimmers. 4 returns, 2 drains, and another return/cleaning port. Most of the time, we run at low speed just to keep the water moving and for the SWG. We run at high speed a few hours a day for our Polaris 360 cleaner. The pump speed is controlled by a Hayward Pro Logic PS-8. I'd like to stick with 115V and also not have to redo my plumbing too much. Looks like maybe a Pentair SuperFlo VS might work, but frankly, I'm having a hard time finding anything (especially anything in stock). Any recommendations? Thanks in advance for all your valuable advice.
