Why do people not leave their black tank valve open when flushing the tank? Valve open, tank won't overfill, why would I want to risk a disaster?
Nick, I close the black valve when using flusher because the flusher does not clean the tank out. After years of use I have found filling the tank several times and draining does a much better job of getting stuff out. Maybe the shape of my tank is difficult to rinse with just the flusher but I do what works best for me. By the way, my accident was a error on my part by hooking water hose to flusher instead of water supply fitting.
