Sewer Tank Flusher
We are getting ready to take our Fifth Wheel on our first trip. I have a water inlet that says this on it: CAUTION SEWER TANK FLUSHER Sewer tank valves must be OPEN when using this inlet. OK...

OK, I have watched videos on YT about flushing the black tank. They seem to recommend using an inlet to fill the black tank so you get a big flush after the initial dump. To do that, you would have to be letting water in that inlet with the valve closed.
Most tank flushers have a "sprayer head" that squirts water on inside of tank. Sort of cleans up tank on inside. So your valve does not have to be closed for tank flusher to clean inside. But I do get better results if I let flusher run while I count to 60 with valve closed, and then open valve. Very important not to get distracted in the process or you might rupture tank.
