ABSTRACT:
A Drinking Fountain attachment for a water faucet is automatically turned on when water is supplied at low pressure and low water flow rates. The assembly includes a hollow body portion between an inlet and an outlet, and the fountain outlet is connected to a central portion of the hollow body. A partition with a central opening extends across the hollow body between the outlet and the point of connection to the fountain. Valve arrangements are provided for normally closing the central passage and for opening it when the water pressure and rate of flow exceed predetermined levels. A flexible, resilient membrane or washer forms a normally open valve but is deflected to close off the connection to the fountain at the higher pressure and flow level at which the valve arrangements operate.
