San T Flush system question
Just purchased a new to us Salem that has a San T Flush system for the black tank. System seemed to work fine on our first trip, I could hear water spraying. In all the paperwork I received, I could find nothing on the San T Flush.
Question: what is the recommended time to use this to spray down the insides of the black tank? And after this time, is it recommended to close the valve and put more water into the black tank to flush all this sprayed down stuff out of the tank?
