An air drive system for a toilet includes a compression cylinder including an air space, a fluid space, a base orifice adjoining the fluid space, and an outlet orifice adjoining the air space, and an air drive passage configured to carry pressurized air to the toilet. The flow of water increases the fluid space of the compression cylinder or increases an air pressure associated with the air space of the compression cylinder.

Air drive system for a toilet

A toilet includes a bowl with a sump and a trapway connecting the sump to an outlet of the toilet. The trapway has a zeta shape and is configured to induce a siphon which provides pressure to suction waste water from the bowl during a flush cycle. A trapway supply conduit is connected to the trapway in a tangential orientation to an upleg region of the trapway. The trapway supply conduit supplies water to the trapway, which follows a contour of the inner surface of the trapway supply conduit and continues in the same direction into the upleg region of the trapway by relying on a fluid flow to follow the curve of a convex surface placed proximate to the flow.

Toilet with efficient water flow path

A toilet assembly includes a flush engine having a bowl, a sump at a lower portion of the bowl, and a trapway extending from the sump. The toilet assembly further includes a first polymeric layer at least partially surrounding the flush engine, the first polymeric layer comprising a foam. The toilet assembly further includes a second polymeric layer provided on the first polymeric layer, the second polymeric layer comprising resin.

Toilet with vitreous china flush engine and polymeric outer structure

A plumbing fixture includes an electrical component insert-molded within a portion of the plumbing fixture, the portion formed from an epoxy. The electrical component is offset from and disposed below an outer surface of the plumbing fixture.

Plumbing fixtures with insert-molded components

An educator assembly for a toilet includes a suction reservoir, a flow driving device, a first nozzle, a second nozzle, and a discharge outlet. The suction reservoir is configured to store a supply of water. The flow driving device is configured to supply a flow of water to the eductor assembly and in fluid communication with the suction reservoir to create a suction port proximate to the flow driving device and the suction reservoir. The first nozzle is at the end of the flow driving device. The second nozzle is downstream of the suction port. The discharge outlet is coupled to a trapway of the toilet and configured to receive discharge from the second nozzle downstream of the suction port.

Eductor assisted flush toilet

A toilet assembly includes a toilet, a non-vitreous fluid delivery component, and a connector assembly. The non-vitreous fluid delivery component is coupled to, and in fluid communication with, the toilet. The connector assembly couples the non-vitreous fluid delivery component to the toilet in a substantially watertight manner. The connector assembly includes a connector body, a nut adjustably coupled to the connector body, and a sealing member disposed on the connector body. The nut is configured to be adjusted relative to the connector body to cause the connector body to compress the sealing member against a portion of the toilet, such that the sealing member creates a substantially watertight seal between the toilet and the connector body.

Fluid connector for toilet

A urinal includes a bowl assembly and a trapway assembly. The bowl assembly includes a body. The body defines a bowl and a cavity. The cavity includes a receiver configured to receive a bracket. The trapway assembly is configured to be located in the cavity. The trapway assembly is configured to fluidly couple the bowl to a drain. The trapway assembly is configured to be coupled to the drain separate from the bowl assembly. The bowl assembly is configured to be coupled to a wall separate from the trapway assembly.
