Is it true that your filter (I have a sand filter) works better when it's dirty? And that you shouldn't backwash until the pressure gauge reads 10 higher than normal? I've been backwashing whenever the pressure gauge goes 5 higher than normal, but maybe I should wait. (Lots of rain here, so water level isn't a problem.) Also, if I don't backwash at least once when vacuuming, I seem to have worse suction. I always thought that was because the filter was clogged, but maybe there's another reason?
