    Abstract: A backflow preventer for preventing a reverse flow of water in a plumbing system including a body having an inlet and an outlet. The body forms an intermediate zone between the inlet and outlet. An inlet check valve prevents the reverse flow of water from the intermediate zone through the inlet. An outlet check valve prevents the flow of water from the outlet into the intermediate zone. An inlet pressure sensor, an intermediate pressure sensor and an outlet pressure sensor provide readings for the respective zones. A controller monitors a pressure differential between the outlet pressure zone and the intermediate pressure zone to compare the pressure differential to a pre-set range. The controller generates a warning/error message when the pressure differential is outside the pre-set range. The controller can also monitor an inlet pressure in the inlet zone to generate a message if the inlet pressure varies inappropriately.

    Abstract: A fluid discharge event detection apparatus measures a change in capacitance to detect the presence of a fluid in a sensing conduit where the presence of fluid indicates a discharge event. The apparatus includes a first conduit, the sensing conduit and a control valve, coupled between the first conduit and the sensing conduit. The control valve is configured to activate and fluidly couple the first conduit and the sensing conduit to one another when the control valve detects at least one predetermined condition of a fluid within the first conduit. A sensor, configured to measure a capacitance value, is disposed about the sensing conduit. A controller, coupled to the sensor, is configured to detect a change in the sensing conduit capacitance value and assert an alarm condition upon detection of the change in the sensing conduit capacitance value.

    Abstract: A test cock is configured to connect to a test cock port. The test cock includes a body portion defining a flowpath between a distal end and a proximal end. The test cock includes an intake stem at the proximal end that has external threads to connect the test cock to the test cock port. The intake stem defines an intake opening connected to the flowpath, the intake opening having a non-circular shape, such as a hexagonal shape. The test cock also includes an extraction tool having an end forming the non-circular shape of the intake opening, the end being sized to fit within and engage the intake opening.

    Abstract: A backflow preventer including a body having an inlet for connection to an upstream portion of a plumbing system and an outlet for connection to a downstream portion of the plumbing system, a first check valve and a second check valve located in the body for preventing the reverse flow of water between the outlet and the inlet. An inlet pressure zone is positioned between the inlet and the first check valve, an outlet pressure zone is positioned between the outlet and the second check valve, and an intermediate pressure zone is positioned between the first and the second check valves. Position sensors sense the positions of the check valves, and pressure sensors sense the pressures in the zone. A controller in communication with the position sensors and the pressure sensors calculates the opening and closing pressures of the check valves.

    Abstract: A heating system includes a heat source. A controller is connected to the heat source and controls operation of the heat source. A first sensor is configured to sense temperature and report a signal to the controller. An input/output (I/O) device is configured to send a set point to the controller. The controller selectively operates the heat source based on a comparison of the signal and the set point. The heat source communicates wirelessly with at least one of the controller, the first sensor, and the I/O device.

    Abstract: A system to monitor and control a water supply includes a plumbing fixture coupled to a water supply; a temperature sensor to generate temperature sensor data indicative of an ambient temperature around the plumbing fixture; and a controller including a battery power supply. The controller is configured to determine a first battery level of the battery power supply, responsive to determining that the first battery level exceeds a first battery level threshold, the controller is also configured to set a timer to a first time duration; the controller is further configured to determine a first temperature for the one or more temperature sensors based on the temperature sensor data and responsive to determining that the first temperature satisfies a first condition, the controller is also configured to cause a transmission of a first notification corresponding to the first condition to a remote computing device.
