Well I really did it now. I removed the toilet and black water tank to get at some rotted flooring and broke the flange off of the tank.
The part I'm talking about is a flange or neck that protrudes up from the tank into the toilet.
Can I repair it or should I toss it and buy a porta potty?
I read one of the replies that talked about purchase of a new tank from Inland RV. Maybe thats the best route. Any help would be appreciated.
