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 ...

A few drops would be common, a few gallons isn't. When you flush leave the value closed for a minute to get more water in the black tank to clean the valve when you open it.
