Waste water
I have a 2017 Jayco 5th wheel. Before departing the campground I open the black water valve, drain the tank then use the internal tank flush for 15 - 20 minutes. I then close the black and grey water ...

I added a twist on valve at the end of the dump pipe. I never had a large volume of rogue liquid, but enough to be annoying and this addressed that. It also allows you to blow some grey water up into the black tank for a little extra flush action if you're so inclined.
