Nicole12,

Still following with you. I still have the Exact same sediment in my pool, I also recently replaced my sand AND I have the same filter as you.

I have inspected my laterals as you have, I have also tried the panty-hose trick with no success. The only thing different is that I have NO DE in my system.

I think they may be on to somthing with the "spider gasket", now if we only knew for sure what part that is

I'll be sure to post when I find out more.
