What RPM setting should I use on my VSP when I backwash the sand filter? (PB did not say.)
Also, what RPM should I use to check for the increase in pump pressure to tell when to backwash? As of now, I generally run at 1800 RPM and no pressure ever registers. If I turn it up to 2800, it sits at 10 psi.
