Abstract: An all-in-one manifold assembly is fabricated separately from and coupled to a pressure vessel of a water filter system. The manifold assembly includes two valve assemblies configured to be rotated between an operational position, a by-pass position and a shut-off position. Rotation of the valve assemblies can occur by manual or automatic rotation. The manifold assembly may further include ports for one or more sensors. A controller can smartly operate the manifold assembly.

Abstract: A relief valve provides pressure relief when a fluid line exceeds a predetermined pressure. The valve includes a body which defines a cavity between inlet and outlet flowpaths. The valve includes a lever arm, which pivots around a pivot point as the valve changes between open and closed positions. A plunger assembly is disposed in the cavity and seals the cavity from the inlet and outlet flowpaths in the closed position. Fluid pressure from the inlet flow path causes the plunger assembly to contact the lever arm to urge the lever arm to rotate. The lever arm engages a spring at a further distance from the pivot point than the plunger assembly, the spring resisting pivoting of the lever arm and urging the valve to remain in the closed position unless a predetermined pressure is exceeded.

Abstract: A backflow prevention assembly is configurable with varying lay-lengths and orientations. The assembly includes coupling assemblies and valve bodies that adjust in length and/or rotation to allow for the varying lay-lengths and orientations of the backflow prevention valves and assemblies with and without certification. A coupling assembly is connected to a backflow prevention valve and includes an outer sleeve and an inner sleeve that is slidingly received within the outer sleeve. The lay-length is adjusted by slidably moving the inner and outer sleeves with respect to one another.

Abstract: A lid assembly being attached to a pressure vessel includes a filter access cap having a top portion, a bottom portion, and a tubular portion extending from the top portion to the bottom portion to define a throughhole, the top portion having a radial slot. The lid assembly includes a seal plate assembly connected to the bottom portion of the filter access cap and configured to rotate relative to the filter access cap to assist in releasing a pressure from the pressure vessel, and a relief valve for releasing non-atmospheric pressure when opened. Further, the lid assembly includes a seal stem located in the throughhole, wherein the relief valve is mounted in the seal stem, and an arm operatively engaging the relief valve and having a proximal end pivotally secured to the lid assembly, whereby when the arm is pivoted in a first direction the relief valve can be opened.

Abstract: A quick connector assembly for connecting a toilet waste pipe to a drain pipe including a toilet carrier base. A collet has resilient radially inward fingers and a lock body secures the collet in place. The lock body has guide tracks with locked portions that define a locked position and unlocked portions that define an unlocked position. A lock nut includes interior protrusions coupled in the guide tracks for movement between the locked and unlocked positions. A guide is slidingly mounted between the lock nut and lock body. In the unlocked position, the lock nut forces the guide into the collet so that the radially inward fingers are splayed to allow removal of a toilet waste pipe for adjustment. In the locked position, the guide is not forced into the collet so that the radially inward fingers prevent removal of the toilet waste pipe for fast and easy assembly.

Abstract: A water heating and treatment system with UV lamp and anti-scale water treatment sanitation for suppression of pathogens including undesired bacterial content in a domestic water system includes a water heater. A cold water supply line to supply water to the water heater includes an anti-scale device, and a UV sanitation lamp. A water heater sanitation loop includes a sanitation loop pump to circulate hot water within the water heater. The water heater controller causes an activation of the water heater sanitation loop and a water temperature of the water heater to increase momentarily to a sanitization temperature above 151° F. for one or more periods of at least two minutes in a sanitation loop mode. A method for treating hot water to suppress pathogens including undesired bacterial content in a domestic water system is also described.

Abstract: An adjustable roof drain for flat and low pitch roofs includes a basin portion and a telescoping basin extension portion. A compression gasket provides a seal between the basin portion and the telescoping basin extension portions of the roof drain. The shape of the compression gasket causes it to be pushed inwardly when compressed so that it seals against the telescoping extension portion to both seal the extension portion and lock it at a selected height.

Abstract: A zone controller works with a modulating unit comprising memory storing an instruction set and data related to thermostats, a plurality of duty cycles for a plurality of zones, a plurality of time periods for the plurality of zones, and a maximum zone load. A processor is operative to provide a modulating signal to the modulating unit based on the maximum zone load. The modulating signal determines operation of the modulating boiler and the maximum zone load based on the plurality of duty cycles, time periods, and data related to thermostats. The zone controller may be further operative to: calculate a first duty cycle for the first zone based on a first time period; calculate a second duty cycle for the second zone based on a second time period; and determine a maximum zone load, which is a greater of the first duty cycle and the second duty cycle.

Abstract: A toilet system has a connector that defines a cylindrical aperture, with a threaded interior surface, around a central axis and that is configured for fixation to a support structure. A cylindrical waste pipe is elongated along the central axis and has a plurality of spaced ribs extending from an exterior surface. A ring-shaped gasket is positioned around the central axis and has a plurality of interior voids, each void corresponding to, and configured to, receive one of the spaced ribs. Further, the ring-shaped gasket has a threaded exterior surface, that slopes toward the central axis, and which is configured for engagement with the threaded interior surface of the connector.

Abstract: A leak detector assembly for use with a backflow prevention device includes a housing defining a passageway for receiving a fluid. A flap assembly couples to the housing for generating a low flow error signal indicating minimal fluid passing through the passageway and a fully actuated error signal indicating significant fluid passing through the passageway. The flap assembly includes a flap mounted in the passageway such that significant flow of the fluid moves the flap to generate the fully actuated error signal. The flap assembly also includes a sensing element on the flap to determine a presence of the fluid without movement of the flap to generate the low flow error signal based on a low flow of the fluid.
