I am working on the equipment section of our specs to take to PB’s for quotes. I have a few questions regarding equipment selection. Side note - One of the PB’s only works with Hayward equipment, or so they say. If true, I have no real concern about using it versus Pentair or Jandy. I’m looking for sizing thoughts/comments for pump, filter and SWG for the following setup:
18’ x 38’ IG gunite rectangle, 3 ½’ to 8 1/2’, approx. 27,000 gallons
2” suction lines separately to 2 skimmers (80’ total)
2” suction to dual main drain (30’ total)
2” return looped return line to 4 returns (130’ total)
2” pressure side cleaner line (leaning towards a Polaris 360 – no booster needed) (30’ total)
2” line to S.R. Smith TurboTwister slide (up to 35 gpm) reduced to 1 ½” at slide (35’)
Automatic cover
Oversized cartridge filter
Maryland (approx. 4 month season – no heater – will likely plumb for a heat pump though)
Electric cost $0.08/kwh
Full sun on the pool, very clean regarding tree debris, etc., and autocover on most of the time
I have tons of other details in mind but these are most that I can think that would affect the equipment specifications. Let me know if others would be helpful.
My very modestly educated guess is that a 1 ½ HP 2-speed pump would be appropriate. My thought being that I could turn the pool over in 12 hrs. at about 38 gpm which would be done at low speed. Then when the slide is on and/or the non-boosted Polaris is running, it would be at high speed. I suppose if the slide is running a lot, the 12 hr. filtration cycle could be decreased due to added return flow. Would a 500+SF cartridge filter for this setup allow me to only clean it once per season? The SWG’s come in various sizes. Would I get the largest size, the 30 to 40K gallon one? Does it make any sense to go smaller due the cover being on often? Not looking to be cheap, just to right-size things.
If you have specific Brand/Model recommendations on anything I’d be glad to have them along with any more general sizing thoughts. If anyone has thoughts regarding pumping/filtration regarding having the cover on much of the time would be interesting too.
Any and all comments are welcome. My goal is to provide a fairly detailed specification list/design to the PB’s stopping short of trying to be a know it all. I’m perfectly happy to listen to a PB’s thoughts on equipment/techniques and am/will be comfortable enough with my knowledge from TFP to not be led astray.
Thanks,
