Exemplary systems comprise a leak detection module with a processor that processes signals from a plurality of low cost sensors installed multiple locations throughout a fluid system, e.g., throughout a house, to determine the presence of a leak in the fluid system. An exemplary electronic plumbing fixture fitting comprises a fixture body including a discharge outlet, the discharge outlet being operable to deliver water via a fluid path; an electronically controlled valve in fluid communication with the fixture body in the fluid path upstream of the discharge outlet; at least one processor programmed to control the electronically controlled valve to selectively control a flow of fluid from the electronically controlled valve out the discharge outlet of the fixture body; and a local water sensor in electrical or optical communication with the processor, operably connected to the fixture body, and positioned to generate a local leak sensing signal having local sensed leak data imposed thereon, the local sensed leak data indicating a leak in the fluid path; and wherein the at least one processor has code causing the at least one processor to determine the presence of leaks in the fluid path using at least the local sensed leak data; and wherein the at least one processor has code causing the at least one processor to, in response to determining the presence of a leak in the fluid path using at least the local sensed leak data, perform any one of or both of the following: transmit to another processor, using communications circuitry, data indicating the presence of the detected leak in the fluid path; and automatically adjust the electronically controlled valve to adjust the flow of water flowing through the electronically controlled valve.

Integrated leak detection

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.

Electronic plumbing fixture fitting including flow switch

The present application discloses systems and methods of powering a solenoid circuit and other circuits with batteries that are at (or near) the end of their functional life.
