I know you gotta empty the full tank, and this is a good plan to catch the "stuff" - but then what?
There's gotta be a less risky way...
Not sure - but I'm thinking of some campsites and other dump areas I've been where there's a well engineered intake to the sewer that includes a catch - I assume for the unlikely event the hose comes or during dumping - that looks like it would take everything down to the sewer without much potential for spillage all over the place. Rinse down with the hose and all is good.
So long as you could get the valve close enough to the right position ....
This is quite a puzzle!!!
