Abstract: An automatic angle stop assembly for a urinal or toilet may include an angle stop adjustment device and an angle stop. The automatic angle stop assembly may automatically control flow through the angle stop to a flush valve. The automatic angle stop assembly may include a motor and an adjustment screw. A method for closing the angle stop may include sensing a flow condition, automatically rotating a motor based on the flow condition, and closing the angle stop.

Abstract: A flush valve assembly comprising a flush valve comprising a flush valve body extending from a flush valve inlet to a flush valve outlet; a flush valve seal having a top face and a bottom face; and a flush actuator comprising a rigid linkage; wherein the bottom face of the flush valve seal is configured to enclose the flush valve inlet; and wherein the rigid linkage is coupled to the top face of the flush valve seal and is configured to lift the flush valve seal to open the flush valve and to lower the flush valve seal to close the flush valve. A rigid linkage is configured to lift a flush valve seal and to lower a flush valve seal at a controlled rate.

Abstract: A comfortable toilet seat, wherein the seat comprises a top circumferential seating surface having an inner edge, an outer edge, a front, and a back, wherein the seat is substantially symmetrical about a bisecting center line from front to back, the inner edge comprises a downward curve from the seat front towards the seat back, the outer edge comprises a downward curve followed by a lesser upward curve from the back to the front, and a back top seating surface comprises a steep upward curve from front to back.

Abstract: A pressure-assist toilet assembly comprising a bowl; and a pressure tank assembly, wherein the pressure tank assembly is configured to be positioned in a bathroom wall cavity upon installation of the toilet assembly. The bowl may comprise an access space at an underside of the bowl, and/or may comprise a utility port positioned on a side of the bowl, configured to allow a bidet seat to be fluidly coupled to an in-wall water source and/or electrically coupled to an in-wall electric source. The assembly may comprise an in-wall support structure, the in-wall support structure configured to be removed from a bathroom wall cavity to provide access to a pressure tank assembly.

Abstract: An automatic faucet assembly comprising a faucet body and spout; an electromechanical valve; a controller; and a power source, wherein the faucet body comprises an electrically conductive material and is configured to be associated with an electric field, the faucet spout is configured to deliver water when the electromechanical valve is in an open position and to not deliver water when the electromechanical valve is in a closed position, the controller, the faucet body, the electromechanical valve, and the power source are in electrical communication, and the controller is configured to detect motion of an end user in the electric field.

Abstract: A siphonic flush toilet system, the system comprising a bowl, a tank, and a rim flush valve assembly and/or a jet flush valve assembly, the tank comprises an interior space configured to hold fluid; and a height, a width, and a depth, based on a tank exterior, wherein the height is from about 17.0 inches to about 29.0 inches; the width is from about 10.5 inches to about 18.5 inches; and he depth is from about 3.10 inches to about 3.60 inches; the flush valve assembly is positioned in the interior space of the tank; and the tank is configured to be positioned within a bathroom wall cavity upon installation of the toilet system.

Abstract: A flush valve assembly, comprising a flush valve comprising a flush valve body extending from a flush valve inlet to a flush valve outlet; a flapper cover having a top face and a bottom face and a front and a back; and a flush actuator comprising a lift rod; wherein the bottom face of the flapper cover is configured to enclose the flush valve inlet; and wherein the lift rod is coupled to the top face of the flapper cover and is configured to lift the flapper cover to partially open the flush valve and to fully open the flush valve.
