Abstract: A siphonic flush toilet system and method of priming the same having a toilet bowl assembly comprising at least one jet flush valve assembly and at least one rim valve; and bowl having a rim and a jet defining at least one jet channel. The bowl has a closed jet pathway to maintain the jet channel in a primed state with fluid from the jet flush valve assembly to prevent air from entering the closed jet pathway. Flush valves may have back-flow preventer mechanisms and/or at least partly flexible valve covers, including specific valve cover structures. Flush activation assemblies may have a flush activation bar connected to the pivot rod and/or an adjustable flush connector located between the pivot rod and the flush activation bar. A kit providing one or more flush activation elements is included. The kit elements may be usable with the toilet systems and methods described.

Abstract: A siphonic flush toilet system and method of priming the same having a toilet bowl assembly comprising at least one jet flush valve assembly and at least one rim valve; and bowl having a rim and a jet defining at least one jet channel, the at least one jet channel having an inlet port and a jet outlet port configured for discharging fluid to a sump area, wherein the sump area is in fluid communication with a trapway. The bowl has a closed jet pathway including the jet channel and extending from the jet flush valve assembly outlet to the jet channel outlet port to maintain the jet channel in a primed state with fluid from the jet flush valve assembly so as to assist in preventing air from entering the closed jet pathway.

Abstract: A wall hung toilet is described which has a toilet body having a toilet body inlet, a back plate having at least a first and a second lower fastener opening therethrough, a toilet body outlet, a bowl and a base. The bowl has an interior surface defining a interior area for receiving fluid, an inlet for introducing fluid to the interior area of the bowl and a bowl outlet. A trapway for passing fluid from the bowl outlet to the toilet body outlet is also included. The base of the toilet body extends from a front bowl portion of the base to a rear portion of the base that contacts the back plate, and the base is configured so as to distribute load bearing forces when applied to the bowl in use towards each of a first area around the first fastener opening and a second area around the second fastener area.

Abstract: A sink is described herein which includes a basin including an upper rim having a back portion, and an interior surface having a sloped surface portion and a bottom surface portion, wherein the sloped surface portion extends from the back portion of the upper rim into the bottom surface portion; a faucet member extending upwardly from an upper portion of the sloped surface; and a drain opening extending through the bottom surface portion, wherein the faucet member is positioned such that liquid from the faucet member flows onto the sloped surface portion into the bottom surface portion and into the drain opening. A method for preventing splashing of a liquid from a sink is also provided herein.

Abstract: Toilet assemblies having various embodiments of a cleaning system are described herein which include a toilet assembly and a cleaning system. The toilet assembly has a toilet bowl, a tank, a flush valve, and a rim in fluid communication with the bowl through a rim flow path from an outlet of the flush valve to at least one rim outlet port. The flush valve is configured to operate in a flush actuation mode wherein the flush valve is able to provide flush water flow sufficient for the toilet assembly to initiate a flush siphon or provide a wash down flush and to operate in a cleaning actuation mode wherein the flush valve is only partially opened to allow for introduction of a cleaning agent and flush water mixture to the bowl that is insufficient to initiate a siphon but sufficient for cleaning the bowl.

Abstract: Toilet assemblies having various embodiments of a cleaning system are described herein which include a toilet assembly and a cleaning system. The toilet assembly has a toilet bowl, a toilet tank, a flush valve, a rim inlet port and a rim flow path (which may be an isolated rim path) extending from an outlet of the flush valve to the rim inlet port.

Abstract: A vent cover is described herein which may be used with various flush valve assemblies, particularly those acceptable for high efficiency and high performance toilets, which vent cover has a wall that includes an upper portion, a lower portion configured to define a vent cover inlet opening for receiving air and/or liquid passing upwardly from within a valve body and/or from within a toilet through a toilet inlet when the vent cover is installed on a valve body, an exterior surface, and an interior surface defining a vent cover passage for air passing upwardly from the vent cover inlet opening.

Abstract: Toilets, kits and methods for installing toilets using a moveable trapway are described in the disclosure. The moveable trapway comprises a conduit body having an exterior surface and an interior surface defining a passage. The conduit body has an upper inlet portion defining an inlet opening configured to receive fluid from a bowl outlet, such as the end of a partial trapway of the toilet, and an outlet portion defining an outlet opening for fluid to exit to a sewage drain pipe. The passage extends from the inlet opening in the upper inlet portion to the outlet opening in the outlet portion. The trapway also includes a connector configured to attach the inlet portion of the conduit body so as to be in fluid communication to the bowl outlet, for example to a partial trapway of the toilet.

Abstract: A siphonic, gravity-powered toilet bowl assembly having a toilet bowl, which includes a bowl inlet in fluid communication with a source of fluid; a rim around an upper perimeter of the bowl defining a rim channel, having an inlet port in fluid communication with the bowl inlet and at least one outlet port; a bowl outlet in fluid communication with a sewage outlet; a direct-fed jet having an inlet port in fluid communication with the bowl inlet for receiving fluid and the bowl outlet for discharging fluid; and a control unit arranged in communication with the bowl inlet for controlling flow from the source of fluid passing through the bowl inlet into the inlet ports of the rim channel and the direct-fed jet, having a first extending rear portion and a second rim channel end portion, wherein the rear portion may extend at least partially into the bowl inlet.

Abstract: Siphonic, gravity-powered toilets are provided that include a toilet bowl assembly having a toilet bowl. The toilet bowl has a rim channel provided along an upper periphery thereof and a direct-fed jet channel that allows fluid, such as water, to flow from the inlet of the toilet bowl assembly to the direct-fed jet outlet port into the interior of the toilet bowl, in the sump of the bowl. The rim channel includes at least one rim channel outlet port. In the toilets herein, the cross-sectional areas of the toilet bowl assembly inlet, the inlet port to the rim channel, and the outlet port to the direct-fed jet channel are configured so as to be optimized to provide greatly improved hydraulic function at low flush volumes (no greater than about 6.0 liters per flush). The hydraulic function is improved in terms of bulk removal of waste and cleansing of the bowl.

Abstract: A sink is described herein which includes a basin including an upper rim having a back portion, and an interior surface having a sloped surface portion and a bottom surface portion, wherein the sloped surface portion extends from the back portion of the upper rim into the bottom surface portion; a faucet member extending upwardly from an upper portion of the sloped surface; and a drain opening extending through the bottom surface portion, wherein the faucet member is positioned such that liquid from the faucet member flows onto the sloped surface portion into the bottom surface portion and into the drain opening. A method for preventing splashing of a liquid from a sink is also provided herein.
