Can find cause of all the dirt/sand in the pool

[bdavis]

The fact that the debris only enters when the filter first turns on, does that rule out some things?

I have the same problem with my sand filter. Although, with mine, you can see the cloud of dirt coming from the return when the pump turns on.

I have been watching this thread closely to see if I can learn anything new.

I plan of posting a new topic when I get back from vacation. See if I can post some pics of said cloud.

Cheers
