Abstract An automatic livestock waterer having a concrete housing. Formed within the upper portion of the housing is a trough which is adapted to hold water. A well spaced away from said trough is also formed within said housing. A float control element for regulating the water level in the trough is coupled to a plumbing element mounted in said well, and which is connected to the water source, providing a conduit for the water from the water source to the float. The housing contains a service aperture adjacent to the well for servicing the control elements and plumbing elements. A hood extends over and around the float and associated heating element.
