Abstract: A toilet that includes a bowl having a sump, a passageway, a fluid conduit and a valve. The passageway includes an entrance fluidly connected to the sump, an outlet, a dam located between the entrance and the outlet of the passageway, and an inlet located between the dam and the outlet of the passageway. The fluid conduit configured to supply a volume of water into the passageway through the inlet. The valve located between the inlet and the outlet of the passageway, wherein the valve is configured to retain the volume of water in a closed position prior to a flush cycle to affect a siphon during the flush cycle.

Abstract: A method of flushing a siphonic toilet that includes retaining a first volume of water in a bowl and an up leg of a passageway that is upstream from a dam, retaining a second volume of water in the passageway between a valve and the dam in a closed position of the valve, activating a flush cycle of the toilet that introduces a third volume of water into the toilet, and moving the valve from the closed position to an open position to affect a siphon during the flush cycle.

Abstract: A siphonic toilet including a bowl, a passageway and a valve. The passageway includes an entrance fluidly connected to the bowl, an outlet, and a dam located between the entrance and the outlet, wherein the dam and bowl are configured to hold a first volume of water prior to a flush cycle. An inlet is located in the passageway downstream from the dam to introduce water into the passageway downstream from the dam. The valve is located between the inlet and the outlet of the passageway, and the valve retains a second volume of water when in a closed position prior to the flush cycle of the toilet to affect a siphon during the flush cycle.

Abstract: A bracket for coupling a urinal to a soil pipe is provided. The bracket includes a body portion defining a first opening configured to be in fluid communication with the soil pipe, the body portion having a first surface configured to receive a resilient gasket. The bracket further includes an arm extending outwardly from the body portion, the arm having a structure configured to receive a fastener for coupling the bracket to the urinal, the structure having a first surface positioned forward of the first surface of the body portion.

Abstract: An air bath has air outlets extending around the side walls of the water basin. Air is delivered to the air outlets through a ring-like air manifold coupled to a blower by conduit. The conduit has a bypass vent that siphons off a portion of the air flow otherwise passing to the air outlets and maintains the blower in communication with ambient air. The air delivery system provides a wider range of bubble densities by allowing the blower to operate at lower speeds without overheating or stalling from back pressure arising from the pressure head of the water in the basin.

Abstract: An air bath has air jets arranged in rows extending around the side walls of the water basin. The rows of air jets are spaced vertically so that they are at different heights within the basin and so that air jets in the higher row(s) realize less pressure from the water in the basin. Air is delivered to the air jets through a ring-like air manifold formed of a single channel or multiple channels, the latter allowing for air flow control to different zones of the tub.
