Why is D.E. leaking into the pool?
• There are only a handful of reasons DE is leaking into the pool. They vary depending on which DE filter you have. (a) Vertical Grid: (1) Too much DE was added. (2) Tear in the fabric of the Grid (3) Crack in the top manifold (4) Bad o-ring on the standpipe (the pipe the DE cluster sits on) (b) Perflex “Bump” Filter.
