aaaarrrggghhhh!
This is really driving me crazy....took filter apart yesterday, cleaned all the grids, held each one up in sunlight, checked every inch of them, looked for a crack in the white plastic tubes inside them, checked the manifold, could see no cracks, air relief looks fine. I admit I'm not expert at this, but I've had the filter apart every year to clean after the pollen finishes falling and never had this issue.
Reassembled, made sure the manifold fit tight on top of the grid tubes, tightened the wing nuts down evenly and pressed the manifold on the stand pipe making sure it was down solid all the way around.
Reloaded the grids w/fresh DE.
Still see what looks like DE coming out of the returns! I'm afraid to let it pump for long that it will just blow all the DE into the pool.
How do I check the multi-port? The handle seems to "spring" back up fine and a week ago I took the top off and the spider gasket looks ok.
thx
