I never, never, ever use my potable water hose for flushing the black water tank. I have a hose for flushing and general clean up and everything else except drinking. I have run into many dump stations that use non-potable water for rinsing and washing down the area. I, for sure, don't want that in my potable water hose.
I think the check valves are installed to prevent sewer water from backing up into the hose, for those that may be dumb enough to use the same hose for potable water and flushing. I even use this nasty hose for draining gray water into a portable tank when there is no sewer connection at the campsite.
So you connect that flushing and drain hose to the campground faucet? How would I know if the faucet is clean after you leave?
My thought precisely. At some point, the whole contraption has to connect to a potable water source. I have a 3 foot length of hose with a back flow check valve on each end. I hook that 3 foot length of hose to my black tank flush (which has its own back flow check valve) then hook my potable water hose to it. That is 3 back flow check valves in series. I feel safe using my potable hose.
