Prior to @ 2010 or so, the vast majority of RVs left the factories without tank flushing contraptions. If you wanted such a gizmo, you added it yourself. Most never bothered to do so. I wonder how everyone survived without them? They work really great ( not sure at what as many are mounted to spray against the gravity flow of the tank outlet) until the cheap plastic anti siphon valve, typically buried in a cabinet somewhere does not seat, and you're mopping up the puddle on the floor. Then not so much.
No need to twist a story into a horror movie! LOL
they are easy to install as I have installed them on 2 different new TT`s. everything is exterior. On my class A its also separate of the living area. no messes and no smells from the black tank either!
