I have a new camper and It has a black flushing connection, never has a camper with this feature and now I was wondering what is the purpose of the black flush
I use our a couple times a year, mid year and the last trip of the year. I have not had a reason to use it weekly. We always have a sewer site so my dumping procedure works pretty good. I just hate hooking up the second hose if I do not need to.
