While it's "OK" in some parks, to use the words from an old Ray Stephens song, unless you "crawl on your belly like a reptile", you ain't getting to that valve.

It's much easier to leave the galley valve open, use that "Chinese finger" hose holder to maintain the slope and let the end dangle and create a P trap to stop the gasses from migrating up the hose.

You sure have a good point John, I guess there are always circumstances that can make a difference on the best practices.
