I do not use mine that way. I use it to fill the tank to almost full after the initial dump. Then I open the valve and let it dump again. I usually do this once or twice and the water coming out is clear with little or no debris after the rinse.
I have a clear elbow I connect to my drain so I can see when the blank tank is truly clean.
We also add Calgon Water Softener to the black tank after flushing as well as a tablet. The Calgon keeps the water very “slippery” to help keep anything from sticking to the tank walls.
