Leaking Black Sewer Valve

We have a 2005 Monaco LaPalma and are having a problem with our black valve not holding. We have a flush king attached, we dump and back rinse extra, extra well and as soon I we put chemical and a couple gallons of water in the toilet the 'blue' water has already filled up the flush king. Does anyone have this problem? Has anyone found a solution to fix it?

Replace the rubber seals and etc inside the valve, or replace the entire valve. I replaced both the grey and black valves in our MH a couple of months ago. Make sure you drain and flush the tanks FIRST!!!

MIght be a good idea to either jack up the valve side of the coach or drive it up on a couple of thick boards before removing the valves. Always a little dripping and a lot of odor involved in this kind of operation.

Replace the valve as they are cheap. Not the most pleasant job but very easy to do.

I have seen here on the forum a valve that fits at the bottom of existing valves and twists on like your sewer hose. That extra valve would stop a leak. But temporary. As said above, the correct fix is to replace the leaking valve. Messy, stinky, but not hard..........ronspradley

Sounds like the perfect job to pay someone else to do
