Im going to guess the OP is too embarrassed to come back. I personally have seen two different incidents where newbies flooded their rv by hooking up the hose to the blackwater tank flush. One was a fifth wheel, the other a C class rental. Im sure you would be heading to the rent all to rent a shop vac.

The guy doing the PDI on mine actually told me to do this - his instructions to flush the black tank were to close the valve, hook the hose to the flushing inlet, turn it on, and have someone - your wife he said, watch by looking down to toilet. She came around the corner and said watch what? I looked at the guy and said you tell her..
