saflyer Posted October 23, 2022 Share Posted October 23, 2022 I have removed my washer/dryer combo unit from my HR 40PLQ. Of course the valves are turned off at the cabinet where the unit was. To simplify winterizing I’d like to disconnect and close off where washer hot and cold lines connect to the main water feed. I believe this would be under the lavatory on the passenger side of the coach. The washer was in the bedroom on the driver’s side and the toilet is on that side also opposite the bathroom sink. To check this out I opened the exterior side panel to inspect these connections. There was a lot of stuff down there so I am going to ask a few questions. In the first picture is, I believe, the potable water tank which is white and below the two black tanks. The potable water tank has a line attached to the top of the tank (red arrow) on the left which is fed to the stub line in the right rear wheel well (second image). What is the purpose of that line? I assume the two black tanks are the black water tank, on the left, and gray water on the right. What is the purpose of the fresh water line feeding the black water tank (yellow arrow)? Now to the original question. I see one hot water line and two cold water ones running from this area across the frame rails to the driver’s side of the coach. I’m guessing the hot water line goes to the washer while one cold water line goes there and the other goes to the toilet. Am I correct and how hard will it be to determine which is which? The next image is of some of the lines under the bathroom sink. Is it reasonable to disconnect the washer lines there or is there a better idea? That and the fourth image showing the hot lines in the bathroom sink cabinet looks like it is an overly complicated system. In that image what is the silver cap at the top of one hot line?
