I open the black water flush valve while the tank is emptying I attach my non drinking water hose to the flush inlet. After emptying the black I empty the gray water then close the gray water valve. I ten turn on the flusher and let it run for a few minutes then close the black valve and let it flush another 2 minutes then open the black valve and let it drain. The last thing I do is to close the black valve and let the flusher run about 1 minute then shut the water off leaving the last rinse in the tank. now I go back in and run one bowl ow water in the commode, drop in a treatment pack and let that go into the tank. In 23 years of flushing this way I have never had a poo pile or any other black tank problem. I might also add that I only dump when full even if I have to add water to fill it.
