Black tank Flush
Sticker by the flush hose port says 'drain valves must be open when rinsing blak tank'. Why must they be open as there should be no pressure buildup, or am I missing something?

Yep, One really bad flood!!! Then sued the manufacture because they were not warned.
If the system is working properly, there will be no inside flooding as water will flow from the vent pipe.
I've proved it several times while using my Flush King. Fortunately it was after many rinses so I had no poop bombs flying thru the air :B
