Grey/black tank issues on 377

Does anyone have a pumbing layout for the 377? Having issues dumping. When I open the main grey tank valve on the camper; nothing comes out. If I open the small inline valve it drains, but still shows tank 2/3 full after it stops.

I have two grey valves and one black. The grey for the bath sink and shower is on the utilities panel, in the compartment, along with the black tank valve. The kitchen sink grey is separate, mid kitchen slide, underneath. Which are you having trouble with?

I would suggest opening the side of the panel (where the filter is) and see if the linkages are connected, and where they go. There are stories out there of mislabeling, where the black label was on the grey tank, and viceversa. If there is no waste in the black, or if you are connected to a sewer dump station, you could pull the other handle and see if they are just labeled backwards....

Thank you! They weren't connected. Had to open up the belly. Sweating my ass off on south padre, but we're back in business!
