Abstract
A water dispenser assembly includes valve cartridges for controlling the flow of cold water from the cold-water inlet and the spout. Each valve cartridge includes a rotatable stem extending from a body. The water dispenser assembly includes a self-closing feature that provides for the automatic shut-off of flow of hot water responsive to release of the handle. The self-closing feature includes a spring held onto the stem by an adaptor. The self-closing feature is contained entirely within the valve cartridge and therefore does not require any modification to the housing.
