I have to agree, the only way out for the water is up and out the vent tube if it gets too full. Now that may be a mess but I see no way it will flood the inside of the RV unless the toilet flapper is not seated.
Whoa!!!!!!!!!!!!!!!! It is not uncommon for other water use sources to be connected to the black tank rather than the gray. Two reasons for this is firstly to try and balance the storage load between the two tanks and secondly to insure that adequate water is getting to the black tank. If the toilet valve holds the back flow, which I doubt because of the pressure, another waste water source is likely to do the flooding. As an example the outflow of our vanity in our head is plumbed to the BLACK tank.
