EC65 DE Filter pushing de from return jets

[fog80]

My DE filter seems to be sending de into the pool through the return jets after bumping. I also noticed that I hear a funky noise coming from the top of the de filter cover when water rushes in, it almost sounds like rocks or something.

I know there are no rocks in there but thats what it sounds like. I took the filter apart, cleaned the filters, checked the plates for cracks and put it back together and I'm still getting that sound and de in the pool.

The good thing is that it only shoots out de for about 10 seconds and then the water from the return runs clear again.

Ideas?

Fog, there's a leak somewhere

It's small, or the pool would be full of DE.

I'd suspect the tube sheets (a hairline crack in the lower sheet would cause something similar)

I'd let it go, as is, for now - next time you open up the filter, check the bottom sheet VERY carefully

I hope you know that you can always 'bounce' thoughts or questions off us

Changed out both top and bottom sheet (had cracks) and about 20 of the "fingers" as well as the diaphram gasket. No more DE in the pool!
