ABSTRACT:
Water is pumped from a container to a refrigerator ice maker and/or chilled water unit. The apparatus for transferring the water includes a motor operated pump, and the motor includes a pair of switches in series for turning the motor off. The switches include a pressure switch actuated from water pressure in the pumped water line and a switch to indicate when the water level in the container is at or below a certain, predetermined minimum. A check valve is in the pumped water line between the pump and the pressure switch to prevent loss of pressure in the line due to the bleeding of pressure through the pump that could otherwise cause the pump to start pumping water when there was no demand for it from the refrigerator.
