Abstract: A leak detection system for plumbing fixtures may include a dual channel system (700) having two channels of water flow to measure fluid flow that is both intentional and accidental. A disclosed embodiment may include a body (710) that is sometimes fastened to a top plate (715) sometimes fastened with socket head cap screws (717). The dual fluid channels may comprise a lower default or first flow path (790). Water flowing though the lower or default path may pass through a paddle wheel assembly (760) and paddle wheel (762) wherein flow rate may be measured by a myriad of systems including magnets or other sensors deposed on the distal ends of the paddle wheel spokes. A leak detection system may also include a single channel system (800) with a flap system. Disclosed systems may include other types of leak measuring devices.

Abstract: A water control, management and measurement system may include a hands-free water control system (100) that may comprise a chassis (104) securing a motor (117) attached to a motor driven gear (118) in geared attachment to a cold water gear (112) and a hot water gear (111) with the hot water gear and cold water gear sometimes in mechanical attachment to a manual on/off lever (110). Cartridge valves (120) may be disposed within manifolds (130) with the manifolds further retaining modular fittings (135). To facilitate hands-free operation, the water control system may be in communication with a foot pedal system comprising a foot pedal housing (350) the housing containing foot pedal in mechanical communication with a potentiometer (375).

Abstract: A hands-free faucet control device includes a water valve assembly, a foot peddle assembly and a pull wire connected there between. A continuously-formed injection molded valve housing includes two cylindrically-shaped apertures disposed adjacent to one another where each has an inlet water port and an outlet water port. A valve is disposed in each of the apertures, where both valves are simultaneously movable between a closed position and an open position. A foot pedal assembly includes a foot peddle bracket and an attached foot pedal, where the foot pedal is movable between an up position and a down position. A pull wire is connected at a pull wire first end to the proximal end of the valve and connected at a pull wire second end to the foot pedal, wherein movement of the foot pedal to the down position by a user moves the valves to the open position.

Abstract: A hands-free faucet control device includes a water valve assembly and a foot pedal assembly. The water valve assembly includes a housing with two input ports and two output port configured to be attachable in series with a hot water pipe and a cold water pipe. A valve includes two through holes and is movable in the housing between a closed position and an open position. In the open position the two through holes are in alignment with the two input and output ports. In the closed position the two through holes are not in alignment with the two input and output ports. A spring is biased against the valve keeping the valve in the closed position. The single valve reduces costs, increases reliability and simplifies ease of installation. The foot actuated faucet can also be configured to remain in the down/on position through various mechanical structures.

Abstract: A water flow regulation system includes a pair of water valves having turnable stems for controlling water flow through the valves and a pair of pinions, one fixed to each of the valve stems. A toothed rack is provided which is sized and configured for engagement with the pinions. A housing supports the valves and rack with teeth of both pinions engaging the rack teeth in order that translational movement of the rack causes simultaneous rotation of the pinions with concomitant simultaneous opening and closing of the valves. A remote control and a sheathed cable interconnecting said remote control and the rack are provided for operation of the system.
