Trouble with grey tank dumping using garden hose

I can't get grey water to come out of a garden hose when attached to my

Are you talking about the clear type adapter you install on your RV drain piping? Like this


If so, this garden hose connection is one way type and used for putting water into the sewer line, not for draining water out of the line.

Good luck.
