I have a Pentair Filter. The pool is a fresh water DE system.
I have replaced the screens, manifold, and backwash valve. Am still getting DE blowback in the pool and the pressure gage goes from 10 (normal) to 30 (psi?) in a few hours after backwashing or cleaning screens directly. I am looking for any suggestions of what else in system I could checkout or replace....
Thanks for help.... I guess the backwash valve is a dial type... It has a handle which is turned to open or lock valve... I lift valve handle to go into backwash mode...
backwash procedure is simply to put in bachwash mode, turn on pump for a few minutes, then stop pump and return valve to normal position (locked)...DE is then added where pool water is pumped to filter.
I do not have a pressure cleaner.
Problem resolved - thank you..

Is your new backwash valve a dial valve?
Explain step by step your back wash procedure.

Filter leak
Also post whether you have a pressure cleaner and whether the line that feeds it is before or after the filter. If it is plumbed after the filter you will have a high pressure reading when it is running in the pool. If it is plumbed before the filter you may be having the blow-back through this line when you add a fresh coat of DE after backwashing.
