My 1 1/2 HP Single Speed Pentair crapped out this week and looking to replace it, have heard the way to go is VS with the efficiency savings.
I have a fairly large pool (35k gal) and the equipment is below grade a bit from the pool with an average of about 50' distance from the skimmers and main drain (2" pipe). I don't currently have a flow meter installed, so is there a way to even calculate Feet of Head or is that even necessary to figure out?
My main concern is with the distance from the pool and being below grade, is that if I go with a VS pump (and spending 2-3x more) I may have to have it on a much higher RPM negating the benefit of a VS pump, and I'm not sure how to figure that out without buying one and installing it. And if I can go with VS, am I able to downsize the HP like what's generally recommended or will I need a higher HP to move the water from that distance?
I know without knowing all the data it's impossible to really know for sure but any guidance would be much appreciated!
