So i know the Pentair Quad DE needs a specific type of valve, but does one exist (that works), which allows me to drain some pool water without having to backwash the DE filter itself (from what I have read, some people complain about the Pentair Quad DE filter and that the grids blow out if you backwash the filter).
So does a valve exist that works with the Pentair Quad DE that allows me to just dump pool water vs backwashing (and also does backwashing on this specific filter work?).
