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?
With the gray tank, the "P" traps only have a water seal. You can flood your TC with gray tank waste.

Wellll- try it - and I guarantee you will NOT like it. The 'flapper" valve may not hold against the pressure. Has happened to several on this forum.
NEVER leave beside the dump valves while using the flusher!! As others have said, I flush then close the dump valve for about 2 minutes and then open it. Do this twice (or more) until only clear water comes thru. Then close the dump valve and hurry to the stand pipe and turn off the water. This leaves a few gallons in the bottom of the tank. But - I repeat -- DO NOT LEAVE while dumping/flushing!
