    I have a 2008 Thor Summit 285bhs (new to me) and without my manual... does anyone know which lever is the gray water vs. the black water? May be a silly question but I dry camp a minimum of 3 months or more a year and if I need to empty the gray water it would help to figure it out without having to "guess". :blush:

    WELL, if you can see the pipe as it goes thru the valves, the 3" is the black. The gray will use a 1.5 or 2" pipe. Usually 2". If you cannot see the pipe and see only the outlet, hate to say it, might be a guessing game.
