Cable Activated Gate Valve Problem
I have a 2015 Blue Ridge 3025RL 5-er. The grey water valve is extremely hard to open and close. It does seal when closed. What I've read is that it is likely the length / routing of the cable. I dropped a large part of the underpinning to look for the valve, but the tank / valve / cable all set on a plywood sub floor, so I can't see how to access the cable. I've also read about lubricating the cable, but don't know how this can be done, since you can't get to the cable. I have tried removing the large flange nut by the pull handle to see if I can access the cable, but there is a large flange nut on the other side of the fiberglass panel. The cable appears to be under the bed slide and was wondering if that would be the cable access point. Any help would be appreciated.
