    Grey Water Valve Leak

    Ours is a 2019 Momentum M395. Yesterday I tried to empty the grey water, but nothing came out. There should have been at least 20 gallons. I closed the valve and turned on inside kitchen sink and let it run. Water trickled out of the valve when in closed position. That means the valve is not closing all the way. I guess I could have said this with a lot fewer words. “Closed grey water leaks”. Now for my question, where exactly is the valve? The underside of the rig is closed up with some kind of cardboard material. Where do I begin.

    The underbelly of your camper is covered with a plastic material called Coroplast (corrugated Plastic).

    To find your valves, remove the Coroplast closest to your drain pipe and follow the drain up to your "Blade Valves", the smaller pipes will be your grey tank (or tanks) and the large pipe will be from your black tank. The valves are reasonably easy to change , however be careful when removing them to not get splashed with effluent.

    PS: if your valves have cables you should replace the cables when you replace the valves.

    PPS: If you have two gray tanks, you may have two different sizes of gate valves (many models do). It would be best to determine which one is leaking and confirm which valve you need with GD Customer Service.
