    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.

  • Patent number: 10465366
    Abstract: A cleaning system for a sanitary fixture (e.g., toilet) can include a cleanser assembly, housing a compartment formed in the deck of the fixture in fluid communication with a waterway leading to the bowl. The cleanser assembly can receive a cartridge containing a cleaning product for insertion into the compartment and introduction into the waterway. The assembly can support the seat and cover of the fixture, and can have a low profile and curved shape that complements the corresponding shape of the seat and cover, and provides a balanced look that makes the assembly appear to be an integral part of the sanitary fixture.

  • Patent number: 10294643
    Abstract: A sanitaryware cleaning system can include a sanitary fixture such as a toilet having a compartment formed on and under its deck. The compartment can house a cleaning tablet that is maintained within a waterway between a tank and a bowl of the sanitary fixture. When the fixture is operated, water flowing down the waterway can dissolve a portion of the cleaning tablet, thus injecting cleaning agents into the bowl along with the water.

  • Publication number: 20140230137
    Abstract: The invention described herein includes a pour-flush latrine pan mountable at a surface that includes a collection basin and a flapper. The collection basin has an upper bowl portion that tapers to an outlet extending through a wall of the collection basin at its lower end. The flapper includes a counterbalance device and a coverplate disposed on opposite sides of a pivot. The coverplate has a shape adapted to cover the outlet of the collection basin when the coverplate is engaged against the lower end of the collection basin. The flapper is pivotally mounted against the collection basin such that the coverplate engages against the lower end of the collection basin when a pivotal force attributable to the counterbalance device is greater than a pivotal force applied to the coverplate that engages the lower end of the collection basin.
