I also have the San-T-Flush system and I will fill the black tank with water at least once after dumping.... and sometimes twice.... to remove all solids from the tank. I can tell from my clear elbow I have installed on my hose. Some people will think I am wasting water but sorry.... I want a black tank that works properly and does not smell.
We have not had an issue with our black tank on two coaches doing both of the above procedures.

I pretty much do the same except I often fill and dump the black tank with fresh water 3 or 4 times. I found that solids still hang around after 2 flushes with fresh water.
