I had the pool guy out for some plumbing work and he thought that my max speed (3450 RPM) on my Intelliflo VS was way too high, even for vacuuming. Said their with a mix of 1.5" and 2" lines, I'm probably stressing the pump without any benefit by running that high.
I filter at 1500 RPM which gives me 4 psi across the sand filter.
I would like to be smart about setting the max speed, since that is used for both priming and manual vacuuming. I can get upwards of 30 psi when I run it at 3450 RPM. Filter pressure and vacuum suction seems to decrease roughly linearly as I decrease RPM. So how low should I go?
