Guess if you had a poop fountain blowing out black tank roof vent yucky water could get into flush line and down to connection and then check valve be stuck open and hose still connected and potable water supply was down some of that yucky water could get into system.
Possibility YES-------probability Pretty LOW
Just saying...not recommending cause I've been accused of using common sense vs following 'standards'
