A water valve and an animal waterer incorporating that valve. A water inlet pipe terminates in an upwardly extending outlet, and a closure mechanism is resiliently supported above the outlet and in turn supports a water retainer. When water is in the retainer to the desired level, the closure mechanism is held against the water outlet, cutting off the flow of water. When the water is below the desired level, the resiliently supported closure mechanism lifts, permitting water to flow from the inlet pipe to the retainer until the desired level is again reached.
