Black tank flush - valves always open?
The label next to the inlet for our black tank flush says that the drain should always be open for flushing. Why is this? Is this really a concern, or is this just there to make sure somebody doesn'...

I am a bit confused. The black tank has at least one vent. The toilet has a flapper that is sealed. If it were not sealed, waste odor would be in your RV. How could you flood the inside of your RV with black tank waste?
Well, if you keep pushing water into your black tank (through the rinser), and tank fills up...That water you're putting in is going to go somewhere.
If toilet seals hold and it doesnt come out from around the toilet, next place I'd think it would go is up the vent line. If that vent line doesn't have a perfect water-tight seal all the way up...Well, thats one way you could flood the camper.
Or, you might just cause a 'geyser' to shoot out from the vent at the ceiling, kinda like what happened in that one scene in the Robin Williams move, 'RV'? Remember that? :)
