I have discussed this with a few folks and most say their gray water drains out through the same hose as the black water. It makes sense to have your gray kind of flush your hose for you, but not this rig. Will attempt to post a pic.Gray water hose....This topic has been moved to another forum. You can read it here: 27937882Gray water hose....Hello all.....new to the forum. We recently purchased a 2008 Pastime 840LT truck camper. After going through all the tie down stuff and the other things associated with putting a camper on our truck, we have questions about the gray water clean out. It seems the gray water valve is a different size than the black water valve. The cap on the gray water valve says 1 1/2". So I have to drain the black water, close that valve, and then hold the 3" hose up to the gray water and then drain that. Does anyone offer a hose that will attach to a 1 1/2" valve? Thanks. Keith
