ABSTRACT:
An animal watering system with automatic protection from electrical power failure, over heating, water supply failure, or restriction and air build-up in the system consisting briefly of a closed loop recirculating water system buried beneath the frost line, a water pump recirculating the water, an electrical heater in the recirculation system, an air storage tank, an air supply line connecting the air storage tank with the recirculating water supply line, a normally closed valve in the air line connecting the air storage tank and the circulating water line, a normally closed drain valve in the recirculating water line, a normally open valve in the line supplying water to the recirculating distribution line and a control circuit for closing the supply valve and opening the drain valve and the air valve in the event of electrical power failure. The system may also include an air vent for automatically purging air from the system so that the water pump may operate efficiently. The system may also include a flow sensor means connected to a control device for automatically turning off the electrical heater in the event of flow restriction or supply failure and purging water from the entire system. The system may also include a temperature sensor for turning off the heater if the temperature of the water in the system exceeds a certain given temperature.
