Sewage Rinse

[Wemustrv]

There is an air gap and a back flow preventer to keep any contamination from occurring. I have a setup in my wet bay to make it easy to rinse the black tank which I do every time I dump. I installed two more back flow preventers in the short hose connection to quadruple the protect against contamination. View attachment 20229View attachment 20230View attachment 20230

Very Nice set up.

We use the rinse system every time we dump. I usually rinse three times if there is no one waiting behind me to dump.

I use a dedicated hose with a back flow preventer with the black valve closed until the tank monitor indicates at least 2/3 full then pull the plug. The black tank rinse also targets and cleans the internal tank sensors as well so I'll repeat the cycle 3 or four times until it starts to run clear.
