Abstract: An elevated flush valve comprising a vent cover may be used with various assemblies, particularly 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. At least the upper portion of the vent cover wall is configured for contacting an interior surface of a valve body at a location above an inlet of an overflow or venting tube on a valve body when the vent cover is installed on a valve body and wherein the valve cover wall is configured to at least partially divert flow of fluid from entering an inlet of an overflow tube or a venting tube on a valve body when the vent cover is installed on a valve body.

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. Flush valves are also disclosed having back-flow preventer mechanisms and/or at least partly flexible valve covers for use with the toilet systems and methods herein.
