Abstract
The emptying of the contents of a holding tank for a recreational vehicle or the like into a land based water closet is greatly simplified, and made much less unpleasant. A portable tank has wheels at one end and a handle at the other, with a discharge valve located adjacent the handle. A deployable stationary support is provided with the tank. The deployable support includes collars engaging stub shafts extending outwardly from the sides of the tank, and two sets of legs which provide a supporting base. As the tank is moved into a vertical position it moves to a point where it is no longer supported by the wheels, but instead is supported by the legs, and the connection between the tank and the legs is automatically unlatched. The tank is then tilted (pivoted) about a horizontal axis so that the discharge valve is right above a water closet. A tube extends from the valve into the toilet to about the point of the liquid level. The valve is then opened from an area adjacent the wheels, and the contents of the tank are discharged into the water closet with a minimum of splashing and in a manner that automatically prevents overflow of the water closet. A pop up level indicator and manually operated vent are also preferably provided in the tank.
