Grey Tank valve 1 sticking
New to site, and I hope I`m posting this in the correct forum. I have a 2013 Jayco Pinnacle 36' RSQS 5th wheel. Grey tank 1 valve is not moving all the way out. Cable will pull out about 1". I have pulled my panels in cargo hold to check the valve, and it will only retract about an inch. other valves retract all the way and fully operational. This one seems to be hung or caught on something, as it will not move any further. Has anybody experienced this problem, and how did you correct it?
