Question about backwashing a DE filter- my multiport valve only has 4 settings and every video I’ve watched, or instruction I’ve read online, talks about a 6 setting valve with one that for “rinse.” My 4 setting valve does not have “rinse” so after backwashing what am I supposed to set my valve to in order to “rinse” the filter grids before backwashing again?
