Abstract
A water-saving diffuser for which a user perceives a relatively higher flow rate than the actual flow rate includes a lower chamber portion housing a distributor disk therein, and an accelerator portion attached to the lower chamber portion, the accelerator portion having a plurality of apertures for producing a multiple-stream output from the water-saving diffuser. A central aperture of the distributor disk can be custom-tailored to produce a specific flow rate for a given water supply pressure. The water-saving diffuser may be used in a water distribution system to provide a predetermined uniform flow rate to all regions of a single- or multi-story building.
