ABSTRACT:
The animal watering tank of the present invention includes a top, a bottom, and a sidewall of double-walled construction filled with insulative material. The top of the tank includes a dome portion which provides an air chamber for housing the water inlet valve of the tank. A water access opening in the top of the tank is normally closed by a buoyant spherical float. An animal desiring a drink can obtain water by pushing downwardly on the float with his head such that the float rolls away from the opening along a converging track attached to the interior surface of the top of the tank so as to present water to the animal. When the animal is finished drinking, the float naturally rolls back into thermally sealing engagement with the access opening. Drainage means and overflow pipes are also provided in the tank.
