Abstract
An automatic dispenser for providing animals with cool fresh liquid (e.g., water). The feeder has self-cleaning and self-refilling features that provide periodic replacement of hot, stale or dirty fluid with cool fresh refills. Solenoid valves are controlled by one or more liquid sensors, a time delay relay, timer and optional thermostat to provide flexibility and customizing of drain/refill cycles as desired in order to reflect varying ambient conditions in which the equipment is operated. Provision is also made for remote actuation of drain and refill cycles.
