Thanks for the response...

I cleaned out the filter, this morning and it didnt seem to make a difference. All I did was open it, and wash away deposits of DE. If there is any more to it than that, I didnt do it.

The problem I have is it, only takes about 20/30 minutes before my flow drops and the pressure raises to where I would need to backwash. We are on a well, so I am trying to minimize how much I backwash. Every 20/30 minutes would be insane.
