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 check valve for a backflow prevention assembly includes a linkage with a platform having a proximal end and a distal end and a first coupling member supported by the platform for engaging a bias assembly. A stop protrudes from the proximal end of the platform to engage a frame of the check valve for limiting travel of the platform. A branch depends from the proximal end of the platform, the branch having a hinge pin configured to nest in a slot defined by check valve. A second coupling member depends from the distal end of the platform for engaging a valve member.

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 leak detection system for a building includes a pressure regulating valve (PRV) having a PRV inlet and a PRV outlet. The PRV is normally operative in a best operating range mode during flow conditions, and a PRV pressure at a lockup pressure during a no flow condition. An outlet pressure sensor is fluidly coupled to the PRV outlet to measure a PRV outlet pressure. A processor is operatively coupled to the outlet pressure sensor. A pressure monitoring process runs on the processor. The pressure monitoring process detects changes in pressure at the PRV outlet when the PRV pressure falls below the lockup pressure while remaining above a setpoint pressure to give an indicia of a building leak condition. A method to give an indicia of a building leak condition is also described.

Abstract: The present disclosure is directed to systems and methods useful for backflow prevention system that includes an actuated valve, a valve controller, one or more upstream sensors, and one or more downstream sensors. Upon detecting conditions conducive to backflow through the system using either or both the one or more upstream sensors, and the one or more downstream sensors, the valve controller causes the actuated valve to close. The system may be enhanced through the use of a qualifying check valve disposed between the actuated valve and the one or more downstream sensors to slow or impede backflow through the system. The system may be enhanced by inclusion of a run-out length between the actuated valve and the one or more downstream sensors to account for the latency in the actuator causing the valve to transition to the CLOSED position.

Abstract: Fluid detection systems and methods using the same are disclosed. In embodiments the fluid detection systems include a sensor module and an electronics module. The sensor module includes a sensor housing that includes a liquid flow path and a sensor element disposed around at least part of the liquid flow path. The sensor element can detect a capacitance of the liquid flow path and provide a sensor signal to a controller in the electronics module. The electronics module can determine a detected capacitance in the liquid flow path based at least in part on the sensor signal, and can determine whether a wet event has occurred based on a comparison of the detected capacitance to a threshold capacitance. Methods using the fluid detection systems and fluid supply systems including the fluid detection systems are also disclosed.

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 valve assembly having a body forming a bucket having a sidewall extending between an open end and a closed end along a bucket axis. A first conduit and a second conduit extend from the sidewall, wherein the first and the second conduits extend along a conduit axis that is perpendicular to the bucket axis. A frame inserts into the bucket along the bucket axis and includes a valve seat and a valve member biased against the valve seat. A guide is provided in the bucket between the closed end and the frame and extends along a guide axis between a first opening arranged in a first plane and aligned to receive fluid flow from the first conduit and a second opening arranged in a second plane and aligned to direct fluid flow through the valve seat. The first and second planes are not parallel to one another.
