ABSTRACT:
An energy free animal waterer includes a base unit having an upstanding tube in which a ballast connected to a cable moves for normally pivoting a closure valve upwardly into engagement with an access opening in a top unit mounted on the base unit. The mechanism for opening and closing the closure valve is totally independent of the water in the reservoir and the top unit such that freezing of the water will not render the closure valve inoperative and the unit may be easily assembled and disassembled.
