I avoid dump station lines whenever possible. But sometimes on longer trips it has to happen. I often use my gray water to flush my black tank. All it takes is a twist on valve at the end of the plumbing.
Open twist-on, open black tank and drain. Close twist-on, leave black valve open, then open gray valve. Gray water will back flow into the black tank. You'll hear it, and when the whoosh stops, close the gray valve. Open the twist-on and let the black drain again. Finally close the black valve, open the gray and/or galley and finish the job.
While all that is going on, no one in line will know anything about a flush going on. And you'll be there watching and working the valves the whole time.
I'm no RV expert and this certainly will do a bit of a black tank flush, but I like the thought of the gray flushing all the poo out of the stinky slinky after the black tank drains, considering it's the drippy, gotta unhook it and store it somewhere part of the equation.
Not sure I want corn and TP sitting in the slinky until next time.
It still does clean the slinky. Assuming you had a good amount of gray to dump. Gravity being gravity, not all that much flows over to the black tank. It just finds its own level. In my case I have gray and galley, so plenty of non-black to do both jobs. Once you've got the twist-on valve. Its maybe 3 minutes extra time.
