ABSTRACT:
A drain pipe dispenses waste water from the vehicle. The drain pipe has a circumferential slot and a gate collar around the drain pipe over the slot. A gate valve is coupled to the gate collar. A gate reciprocable between a closed and open position is provided. A drive rod coupled to the gate with a free end is formed with a C-shaped hook. A pivot bolt is provided. The lever is rotatably supported on the pivot bolt. A handle has an intermediate extent. The intermediate extent is slidably received in the C-shaped hook whereby moving the handle toward the drain pipe closes the gate valve and moving the handle away from the drain pipe opens the gate valve.
