cleaning pool filter

[dkdog68]

i have a question along the same lines...how often should i backwash? also at what pump pressure is a good indication that you need to backwash? i have a hayword sand filter (100 lbs) with a 1 hp pump. my pressure right now is about 15 to 17 psi.

When clean, my 1.5 HP pump and sand filter runs at 5 to 7 PSI. I backwash when the PSI hits 12 PSI.

Okay...thanks for the advice.
