Hi everyone...luckily I found this great resource.
I have a FNSP 48 DE filter, and it has been doing fine until this weekend. I did a backwash first, and then when I went to add more DE in the skimmer, the DE started coming out of the jets. Now the bottom of the pool has DE or sand all over the bottom.
I disassembled the filter to clean and inspect the grids. I did not see any holes or tears in the grids. The only thing I did see is that at the top of several grids...the little plastic piece that fits into top manifold...are brittle and some have broken off. Would this be a likely cause of the DE coming out of the jets? Also, the internal air bleed assembly that comes out the top of the manifold has a hole in it. Is that supposed to have a hole on the end? Could this be a cause?
If anyone knows of any other reason, I sure would appreciate some feedback.
Thanks in advance,
Bruce
