My Backwash valve has been getting harder and harder to pull up (It's the kind you twist to unlock and then pull up to select backwash mode) so i bought some new o rings and want to replace and lube them. Well, I can't get the valve to come out. It will pull up to the same point as the backwash selection but not any further with all the screws removed.
I tried a little dawn dish soap but that did not help at all.
Any advise?
