Hi, guys.
After back washing DE filter yesterday, I noticed that back wash valve cannot be pushed to the bottom, and it's kinda stiff when i tried to twist it. So I pulled out the valve, rinse it off. After putting lubricant on those o-rings, the valve can be push to bottom and easy to twist to close and open. Unfortunately, something occurring today concerns me. DE filter pressure raise so fast since this morning, it started with 20psi, but it reached 28psi after a couple of hours, then 32psi. I worried if there were anything inside the filter causing that, so I open it up and completely washed the filter around noon. After I put back, pressure dropped to 20psi, but, after a few hours, pressure comes back to 28psi again. I'm running out ideas what I should do now, any suggestion and help would be appreciated.
P.S, is it possible that I didn't put enough D.E into filter after wash? I ran low on D.E at home, so I only put 6 cups of D.E in after wash it.

I should've posted this thread in the section for Filter, my bad. Can anyone move the thread right section, please? Thank you.
