On the passenger side in the AH bay, look at the waste tank upper left hand corner. You should see a 1/4 turn valve with a hose connection. You can hook a hose to that connection and flow water directly into the tank. The position of the 1/4 valve will determine whether the water enters the top or the bottom of the tank. I actually ran a hose over the top of the waste tank so I could provide water from the wet bay.

I do a quick rinse of the tank at every dump, it seems to keep solids from building up on the bottom of the tank. Since I started that practice, I find that I get no or very little swamp gas aroma from the roof vents.

CAUTION ! Do not run water into the waste tank and walk away. There is no mechanism from overfilling the tank.
