I have a Grey Tank I don't know what it is for

Thank you all for your feedback concerning my grey tanks. We figured it out! I thought the kitchen sink drained into the main grey tank, but it drains into that rear RV tank. Since I generally keep the grey water tank open I did not realize this.

Someone is messing with your head....

I have as 2010 Cougar. Near the front of the RV it has a grey tank that serves kitchen and bath sinks and shower. There is also pull lever near the back of the RV and a small sign on the side of the RV "grey tank." I have no idea what this is for. None of my manuals show this. Any idea? Thanks

And it’s empty and doesn’t run any water no matter which sink or faucet you use?

Do you have an outside kitchen with sink?

Might help if you give the full model info and maybe a picture or two.

I assume you are saying you have a drain near the front, maybe with the black tank, then an extra drain near the back?

mine, not a cougar, has 2 grey tanks, one for the shower and bath sink and one for the kitchen sink. Both levers, and the black, are in the same spot. But, I have seen trailers with drains in 2 places.

Boy howdy when you pull that lever you will drain your Grey tank that has collected fluids from both sinks and shower.
