Abstract: In a method of monitoring fluid usage in a fluid system, a proportional control valve is provided, including a valve element operable to control fluid flow from a fluid source to the fluid system. A first pressure upstream of the valve element and a second pressure downstream of the valve element are measured to identify a pressure differential across the valve element. In response to the identified pressure differential, the valve element is adjusted to one of a plurality of flow positions to adjust the pressure differential across the valve element to substantially match a predetermined pressure differential. A flow rate through the proportional control valve is determined based on the first pressure, the second pressure, and the adjusted flow position of the valve element. Based on the determined flow rate over time, an amount of fluid usage in the fluid system is determined.

Abstract: The present invention provides an electronic plumbing fixture fitting including a measurement system. The electronic plumbing fixture fitting includes a user input module. The user input module includes a mechanism to receive from the user numerical value(s) of parameter(s) for water to be delivered through a discharge outlet of the electronic plumbing fixture fitting (e.g., volume or volume and temperature) and a mechanism to deliver to the user the numerical value(s) of the parameter(s) via the water delivered through the discharge outlet of the electronic plumbing fixture fitting.

Abstract: A disposal with above sink installation where the disposal can be inserted through a drain opening in a basin from above the basin. The disposal includes a housing, a grind assembly, a motor assembly, and a mount assembly. The mount assembly is operable to mount the housing to the drain opening in the basin. The mount assembly includes a flange and a securing mechanism. A diameter of the outer surface of the housing is less than a diameter of the drain opening in the basin. The housing is operable to be inserted through the drain opening in the basin from the top surface of the floor of the basin. The housing is operable to be secured to the drain opening in the basin from the bottom surface of the floor of the basin.

Abstract: The present invention provides a waste system including a disposal with multiple inlets that can receive water and waste materials from multiple basins.

Abstract: The present invention provides an electronic plumbing fixture fitting including a preset feature.

Abstract: The present invention provides an electronic plumbing fixture fitting including a demonstration feature.

Abstract: The present invention provides a disposal with sensor and light system where a sensor detects a presence of a user in one area near the disposal and a light illuminates another area near the disposal.

Abstract: The present invention provides an electronic plumbing fixture fitting, such as an electronic faucet, that includes an electronic valve, a mechanical valve, and a flow switch. The flow switch is used to determine if the mechanical valve is activated. The determination whether the mechanical valve is activated can be used to control the electronic valve.

Abstract: The present invention provides a pullout faucet with a mounting system that is easier to manufacture and assemble. The pullout faucet includes a cage and a mounting retainer. The mounting retainer is separately formed from the cage.

Abstract: The present invention provides a disposal snap ring installation tool that enables a consumer to easily install a disposal snap ring. The disposal snap ring installation tool includes a body and a handle. The body includes a base and an arm. At least a portion of the handle extends angularly downwardly and outwardly relative to the outer wall of the base. The base is operable to be inserted into a circumferential gap in a disposal snap ring. The arm is operable to receive an end of the disposal snap ring such that one end of the disposal snap ring abuts one of the first end wall and the second end wall of the base. The base is operable to be removed from the circumferential gap in the disposal snap ring by pulling the handle radially outwardly in a plane of the disposal snap ring.

Abstract: The present invention provides a faucet with a hose connection that is easier to assemble, install, uninstall, and disassemble. The faucet includes a hose, a valve body, a mounting shank, a first hose retainer, and a second hose retainer. The mounting shank includes a first end and a second end. The first hose retainer includes a base section. The base section includes a first hose opening. The second hose retainer includes a first end section, a second end section, and an intermediate section. The first end section includes a second hose opening. The second end section includes a first hose retainer opening. The intermediate section includes a first hose retainer channel. The hose is fluidically connected to the valve body at or near the first end of the mounting shank. The hose is mechanically connected to the valve body at or near the second end of the valve body.

Abstract: The present invention provides a plumbing fixture fitting with a diverting system.
