Ok, sorry for the silly pun.
Anyway, 16x32 inground, vinyl-lined pool, Raypak 266 NG, Rainbow 320, that is used for 1st half of summer, Liquid Chlorine once CYA rises, 2 returns, 1 skimmer, 1.5" plumbing, Hayward S244 300lb sand filter (Zeolite), no water features or anything else...pretty simple. Filter pressure is always around 18psi, rarely backwash, pool not really heavily used but always open. It's all about 'atmosphere', donthca know?
Current Pump is 1HP, 1.25 SF Challenger that has been running nicely for 18 years now. Runs generally 6hr on, 6hr off and all is well. Not sure why, but I think I'd like to run a pump 24hrs a day at a lower, quieter speed, well, just because. If I went to a 2 speed pump, would the lower speed be enough to keep the heater/chlorinator/future Auto Pilot salt generator happy, flow-wise?
The Challenger has been a good, reliable pump for 18 years now but methinks it's not exactly 'efficient' and well, it's certainly not the quietest pump out there. I always kinda thought it was kinda overkill for our simple little watering hole, not sure why. Any thoughts? Guess I could just go get a 1hp, 2-speed SuperPump for about $400 and see how that does. I see many pumps/motors now rated for 'Standard efficiency' as well as 'Energy Efficient'; is there really that much of a difference? I don't mind a higher upfront for decreased ongoing costs. I wonder if these newer variable speed pumps have the 'beef' to run for the next 18 years?
I dunno, maybe I'm just in the mood to buy something new...$1K on a IntelliFlo XF VS??? Now that'd be overkill!
