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...

Had a similar problem a while ago. I let the tank empty, then poured in PineSol and a few gallons of hot water. Waited a bit, then used a hose to direct pressure up into the drain valve. It cleared the paper mass that and formed a plug. Worked for me.
