When do I backwash?


You backwash when the filter pressure gauge reads 10 lbs more than the normal operating pressure when the filter is clean.  This varies on every pool, so know what your regular pressure is when you have a clean filter.  We recommend 3 – 4 minutes for a sand filter and multiple, shorter backwashes for DE filters.
