Abstract
Abstract A drinking water supply apparatus is described which is capable of providing a constant supply of water by gravity flow from a dispenser. The apparatus is especially useful for converting existing bottle-type water dispensers into a unit which delivers readily available tap water by gravity flow from the existing dispenser outlet valve while avoiding any return flow to the tap water supply line.
