Pentair DE filter leaking at backwash port
I have a Pentair (Pac Fab) series 2000 DE filter with built in backwash valve that is leaking out the backwash port at a rate of 6 or 7 drops per minute. The filter is only about 7 yrs old. I disassembled completely and cleaned everything but still leaks. I assume that it is the seal on the valve. It is a Noryl rotary valve with integrated tapered seal. It was not obvious to me how to remove the valve body from the casting. Is it pressed in? I see that I can purchase the seal separately from the valve body or together as a assy. Is this something I can do myself, I'm pretty handy. Thanks in advance for your help.
