The user interface is provided on the spout. The mixing valve is contained within the body and is configured to be in fluid communication with a hot water source and a cold water source. The first capacitive sensor pad is provided below the user interface. The second capacitive sensor pad is provided below the user interface laterally adjacent to the first capacitive sensor pad, and is physically separated from the first capacitive sensor pad.

A method for programming a water delivery device having a first optical communications interface is provided. The method includes physically coupling a communications bridge to the water delivery device. The communications bridge includes a second optical communications interface and a separate data communications interface. The method further includes transmitting information from a user device to the communications bridge using electronic data communications between the user device and the data communications interface; generating, by the communications bridge, an optical signal comprising the information received from the user device; and transmitting the optical signal from the communications bridge to the water delivery device using optical communications between the first and second optical communications interfaces.

A faucet-mounted filter system includes a body forming a fluid chamber having a water inlet, a quick connect device positioned adjacent the water inlet for mounting the filter system to a water faucet, a filtered water flow path disposed within the body and in fluid communication with the water inlet, an unfiltered water flow path disposed within the body and in fluid communication with the water inlet, a diverter valve disposed within the fluid chamber and operable to open and close the filtered and unfiltered water flow paths, a seal, an actuator engaging the diverter valve to open and close the filtered and unfiltered water flow paths, a flow meter connected to the body and in fluid communication with the filter flow path, a filter housing connected to the body and having a reservoir, and a filter cartridge disposed within the reservoir.

A connector assembly for connecting a valve seat with an outlet pipe and a faucet having the same are provided. The valve seat includes an outlet channel provided with an insertion hole and a first axial connection portion arranged at an outer cylindrical wall thereof. The first axial connection portion is located below the insertion hole. The outlet pipe includes an inlet end provided with a mounting portion and a second axial connection portion arranged at an outer surface of the outlet pipe and located close to the mounting portion. The second axial connection portion is detachably mounted into the first axial connection portion from bottom up to form a rotation point. By the outlet pipe rotated around the rotation point, the mounting portion is forced to be mounted and positioned inside the insertion hole of the valve seat firmly with sealing effect.

A plastic water channel main body of a temperature adjustable water tap includes a plastic H-shaped frame and a water sealing plate. A water outlet leading upward is disposed in the middle of a transverse pipe of the frame. Two ends of the transverse pipe are connected to valve seats protruding upward. An inner hole of the transverse pipe enables the water outlet to communicate with inner cavities of the two valve seats. The bottom of each valve seat is provided with a water inlet and a water inlet pipe extending downward. Each water inlet pipe communicates with the water inlet of the corresponding valve seat. The front of the transverse pipe is provided with a channel communicating with the inner hole and cutting into the inner cavities of the two valve seats. The water sealing plate is fixed on the opening of the channel and seals the channel.

A faucet-mounted filter system includes a body forming a fluid chamber having a water inlet, a quick connect device positioned adjacent the water inlet for mounting the filter system to a water faucet, a filtered water flow path disposed within the body and in fluid communication with the water inlet, an unfiltered water flow path disposed within the body and in fluid communication with the water inlet, a diverter valve disposed within the fluid chamber and operable to open and close the filtered and unfiltered water flow paths, a seal, an actuator engaging the diverter valve to open and close the filtered and unfiltered water flow paths, a flow meter connected to the body and in fluid communication with the filter flow path, a filter housing connected to the body and having a reservoir, and a filter cartridge disposed within the reservoir.

A faucet user interface illustratively includes a support extending along a longitudinal axis, and a handle operably coupled to the support. In an illustrative embodiment, the handle is rotatable about the longitudinal axis for controlling a first water parameter (e.g., water temperature), and the handle is axially movable along the longitudinal axis for controlling a second water parameter (e.g., water flow rate). In another illustrative embodiment, a first handle is rotatable about a longitudinal axis of a delivery spout for controlling a first water parameter, and a second handle is rotatable about the longitudinal axis of the delivery spout for controlling a second water parameter.

A faucet assembly including a housing body, a valve assembly received within the housing body, and a waterway assembly having a base supporting the valve assembly. A face seal is positioned between the valve assembly and the base of the waterway assembly. An upper radial seal is positioned between the valve assembly and an internal surface of the housing body, and a lower radial seal is positioned between the base and the internal surface of the housing body.

Provided are internal waterway assemblies for faucets comprising a valve assembly comprising a valve water way portion, a bridge comprising a passageway therethrough in fluid communication with the valve water way portion and the bridge having a spout receiving portion having a passageway therethrough; and a spout tube configured to be positioned in the spout receiving portion of the bridge. The spout tube is in fluid communication with the passageway of the bridge and configured to deliver water out of the faucet.
