    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 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: A water heating and treatment system includes a water heater, a hot water outflow line from the water heater, and a cold water supply line to supply water to the water heater. The cold water supply line includes at least one of an anti-scale device, and a UV sanitation lamp. A mixing station supplies a temperature regulated heated water to one or multiple temperature zones. A mixing station supplies heated water to at least a first temperature zone at a first hot water temperature. The water heater, the anti-scale device, the UV sanitation lamp and the mixing station are contained in a single enclosure having at least one sliding transparent wall through which components can be viewed. A plurality of pipe connections passing through a rear panel of said single enclosure are also described.

    Abstract: A heating, ventilation, and/or air condition (HVAC) controller assembly to reduce undesired air currents includes a front cover, a back plate configured to be removably secured to the front cover, HVAC controller circuitry, a plurality of wire openings, and an air intrusion barrier configured to extend across the wire openings. The HVAC controller circuitry is configured to be electrically coupled to a plurality of wires extending through a hole in the wall to adjust an environmental characteristic of in a controlled space. Each wire opening is configured to receive only a single wire and each wire is configured to extend through a different one of the wire openings. The air intrusion barrier is configured to receive the wires to generally form a plurality of seals against the wires. The wire openings are configured to substantially support the wires to reduce movement of the wires relative to the air intrusion barrier.

    Abstract: A tankless water heater (TWH) isolation valve includes a valve body having a plug valve port, a TWH port, a water distribution system port and a drain port. A plug valve includes at least one plug seal. The plug valve is controlled by a rotatable plug valve handle. The plug valve is disposed through the plug valve port and within the valve body. The rotatable plug valve handle includes a first plug valve handle position and a different rotated second plug valve handle position. In a normal operating mode in the first plug valve handle position, the TWH port is fluidly coupled to both of the drain port and the water system distribution port. In a drain mode, the TWH port is fluidly coupled to the drain port, and the water system distribution port is closed to the TWH port as blocked by the plug seal.

    Abstract: A closet carrier assembly for a wall-mounted toilet comprising a face plate having a front face and a back face. Spacing rods, extending from the front face, have a threaded distal end with a nut to act as a stop. A retainer plate mounts on the plurality of spacing rods against the stop and defines an opening with opposing earhole extensions. A waste pipe has a front end and a cuttable back end. The front end has opposing tabs sized and configured to pass through the earhole extensions. The front end also has ridges so that when the tabs are passed through the earhole extensions and the waste pipe is rotated, the waste pipe is fixed in place by the retainer plate being captured between the tabs and the ridges.
