You have two gray water and two black tanks. the valves in the front compartment controls the first black tank and the bathroom gray tanks. There is a pull valve behind the tires for the 1/2 black tank. Now there is suppose to be a gray tank valve just in front of the tires. But mine is hidden in between the tires not mounted where it's suppose to be. So look for it between the tires. to shut it off.
