black tank wont drain
I have a 2017 Minnie Winnie and am having trouble with my black tank draining. I dont know if the issue is the gate valve outside that is stuck or what. I let it sit until; next stop about 150 miles. ...

Look from under neath to see if the slide valve/gate is opening.
Curious. HOW would you be able to see that?????? The only thing visible is the steel rod that comes out and in. IF the steel rod has separated from the valve blade(very common on this type problem) there is nothing to see, unless you have a straight line of sight from the dump cap to that valve. To the OP, IF the rod has indeed separated from the blade AND you have enough room, I drill a 1/4 inch hole on the END(opposite the rod) in the middle of the valve body. Have a 1/4 rod handy and insert into the hole(a little sewage water will dribble out) and use that 1/4 dowel rod to push the blade OPEN and drain the tank. Once drained, flush and then replace the 3 inch valve. Doug
