Black Tank Valve Stuck

[mckincb]

Hello,
The black tank valve is stuck in the closed position on our North-point 377 RLBH. I assume the cable is rusted shut. Any advice on possible solutions would be greatly appreciated.

Thanks

PB Blaster every day for a week might loosen it. Then WD 40 every outing. Don't know why they don't use SS cables on these rigs. Not much more money but a lot more reliable.

That sucks! Someone else posted this past week a similar issue with their grey tank valve.

If you can do a little snooping and figure out where the valve is located, you can cut the underbelly to gain access. Recommend cutting a hole at least 1 foot by 1 foot (if your confident of the valve placement. Or go bigger like 2 foot by 2 foot. Only cut three sides of the box, leave one side (side closest to the front of the rig) uncut, use that to make a flap. Once repaired or "fixed", tape the flap shut.
