First time poster, but I think I have done most of my homework. I would really appreciate any advice some of the more experienced members may have.
I am preparing to have my pool renovated (Resurface, Deck, all new Equipment). I have a 25K gallon IGP (16x32), 1.5" pipe all around. The installer (or renovator) wanted to sell me a single speed 1.5HP hayward. Even though our power is not overpriced here (yet) I want to save money where I can. I asked him for a two speed pump, and he seemed amused, but gave me a quote nonetheless for a 1.5HP (Max, 1.875 SFHP) Northstar 2 speed. I still think this may be overkill looking at the flow charts as I have a very simple setup with only short runs to and from the pool. I will outline the setup below:
* One 1.5" intake roughly 10 feet from the skimmer. The main is looped through the skimmer, I assume I have to connect a hose between the two ports to pull from the main, though I have not tested this.
* Pump, yet to be determined
* Cartridge filter, most likely Hayward StarClear Plus C17502
* 1.5" return to pool, 20 feet to the furthest outlet (2 outlets total)
My goal is to run the pump at low speed for most of the day to save money. I don't think my setup will have much TDH at low speed. Does this Northstar 1.5HP 2 speed make sense, or would something like a Pentair WhisperFlo WFDS-3 (3/4HP Full, 1.25 SFHP) be a better fit? Any help is appreciated.
Thanks for reading
Edit: Does anyone have anywhere online they can recommend to buy the Whisperflo WFDS-3/24?
