Hey Guys. Just opened my pool and it was all sparkly and clear. Checked my levels and to my surprise found out that I still had FC in pool from the winter. Filled up the pool and started the filter last night around 6pm. Let it run all night and this morning went to check on things. Pool was a little cloudy so I decided to add a little DE. While adding the DE it looked like it was making it past the filter it was a little cloudy out of the return.
Decided to backflush out the DE and found a problem. Very little pressure while backwashing.
Tried all filter settings and I get very little pressure on all of the other filter settings except filter.
When I put to Backflush/Rinse/Bypass to waste it comes out but not at high pressure.
I took off spider gasket and It looks OK to me. then I opened up filter to look at sand and the sand was not channeled and looked fine to me.
Cleaned everything off and test again same thing. When I back flush I get no dirt coming through. I know theres is some because when I opened the filter there was some debris that should have been backflushed out floating on top of the sand.
