Black Water Valve Won't Close
The black water dump valve won't completely close, and it lacks about 1/4 inch of closing completely. I have never had any problems with this before. I'm thinking there may be some toilet paper lodged...

I put on a third valve over the outlet. Then I can close it and use the grey tank to back flush. It is a heavy stream of water and it will dislodge stuff very easily.
