I just installed a Hayward Max-Flo VS. I have it running at 1500RPM, 23hrs a day. according to the manual, Max flow rate for 1.5" PVC @ 3000rpm is 45gpm.
Any way to calculate head loss and plumbing etc.. The pool is 15ft from the pump at about 2ft above the water line.
Does it help if I run it faster, then slower throughout the day or as long as there's enough water turn over?
