The present invention provides an electronic plumbing fixture fitting, such as an electronic faucet.

Spray Device

A showerhead has at least a first set of nozzles and a second set of nozzles for discharging water. The showerhead discharges water according to one of multiple water delivery functions, where a first water delivery function corresponds to water being discharged through only the first set of nozzles, a second water delivery function corresponds to water being discharged through only the second set of nozzles and a third water delivery function corresponds to water being discharged through the first and second sets of nozzles simultaneously. The spacing between the first set of nozzles and the second set of nozzles is carefully selected so that the third water delivery function corresponds to the integrated nozzles of the first and second sets of nozzles. As a result, the third water delivery function provides a coherent and balanced water flow resulting in a more pleasant feel.

Integrated multi-function showerhead

A multi-function showerhead has at least a first set of nozzles forming first curves and a second set of nozzles forming second curves. The showerhead discharges water through the first curves when a first water delivery function is selected and through the second curves when a second water delivery function is selected. The first curves and the second curves are interleaved so that a coherent and balanced spray pattern is provided resulting in a pleasant showering experience, regardless of the selected water delivery function.

A new article of manufacture, for example a faucet or other article of hardware, has a specified decorative color, and is resistant to corrosion, abrasion and attack by chemicals. The article includes a substrate, one or more corrosion resistant layers applied to the substrate, a thin transition layer having a composition that varies systematically from a first composition to a second composition and in which the first composition has, at least in part, the function of corrosion protection, and in which the second composition determines the visible color or that portion of the substrate to which the transition layer is applied.

A faucet spout fixture provides for spout mounting and removal from above a supporting surface such as a sink deck, without disconnection of the water supply conduits beneath the sink deck. The fixture includes a faucet spout which has a water passage and a water discharge in communication with the passage. There is a water inlet in the spout which communicates with the passage. A water supply assembly is located beneath the supporting surface and there is a spout waterway adjustably connected to the water supply assembly, which spout waterway extends into the spout water inlet. There is a clamp member adjustably mounted on the spout waterway to be positioned against and on top of the supporting surface sink deck. A spout fastener extends through an opening in the clamp member and is held in position therein by a portion of the spout waterway. The spout fastener adjustably cooperates with a threaded bore on the spout to removably fasten the spout against and on top of the supporting surface.

Modular lavatory faucet spout mounting

A new article of manufacture, for example a faucet or other article of hardware, has a specified decorative color, other than brass, and is resistant to corrosion, abrasion and attack by chemicals. The article includes a substrate, one or more corrosion resistant layers applied to the substrate, and an outer layer, applied by PVD, and chosen from only one or more of Zr, Hf, C and N. The outer layer provides the desired, other than brass, color of the article, the desired chemical and abrasion resistance, and which layer, when in contact with air or water becomes passive in a manner similar to chrome.

A process for measuring the quantity of lead on the waterway surface of a brass component, for example a brass plumbing fixture, includes the steps of filling the brass component waterway with an aqueous solution of an acid which removes lead from the surface of the brass component. The acid solution is removed from the waterway after a time period which is sufficient to remove substantially all surface lead from the brass component, but which is insufficient for the acid to remove significant surface zinc and copper to expose surface lead. The quantity of lead per unit surface area of the brass component can then be determined by the use of the volume of the acid solution, the surface area of the brass component and the concentration of lead in the acid solution.
