Particles coming out of the return valve

[kramer840]

I think I may have figured out the problem. Over the weekend, I took out (and apart) the filter grid. I found that 2 of the grids had tears in the bottom, so it cost me about $80 to replace them. Put it back together, turned on the filter, added DE, and crossed my fingers. No particles coming out of the return jets (so far).

That would do it! Since you're not still leaking stuff, it sounds like you may not only have found "some" leaks, you found "the" leaks!
