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.

Primed jet toilet

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.

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. The cleaning system has a reservoir for holding a liquid cleaning agent having an outlet port in fluid communication with the interior space of the reservoir body; a housing to receive the reservoir, a supply conduit in fluid communication with the interior of the reservoir; a flow control device capable of controlling flow through the supply conduit; and a control system activatable by an actuator feature, wherein upon activation of the actuator feature, the control system is adapted to initiate a clean cycle by: operating the flow control device for a first period of time sufficient to deliver a dose of a liquid cleaning agent from the supply conduit to an interior space of the flush valve in a closed position, the flush valve configured for delivery of fluid to the rim inlet port, and operating the flush valve to open the flush valve to introduce flush water to carry the dose of a liquid cleaning agent through the rim inlet port into the toilet bowl.

Novel plumbing products, including faucets, are fabricated, e.g., using metallic 3-dimensional or other 3-D printing techniques, to have complex geometries, such as multiple channels that may diverge and re-converge near the spout. The geometries of the various channels can resemble interwoven net-like patterns that define various shapes between the channels. The plumbing fixtures may be formed from one or more of stainless steels, INCONEL, brass, bronze, polycarbonate, PVC, acrylics, rigid polyolefins, PET, carbon fiber, AES, or other plumbing fitting suitable corrosion resistant materials. In some embodiments, the handles of an exemplary faucet can include the same or a similar multiple channel configuration as the spout, providing an advantageously, aesthetically pleasing faucet system. In exemplary embodiments, faucet spouts and their handles are formed so as to couple to standard faucet underbodies, standard valve platforms, or standard threaded hose/waterway connections.

A cost-effective and practical antimicrobial glaze system and glazing process is disclosed herein. The antimicrobial glaze/enamel may comprise at least two layers: a base layer and a top layer. The base layer may contain a typical or normal glaze widely used in sanitary ware, having a low level of zinc oxide. The base layer glaze may be directly sprayed on the clay body surface. A thin top glaze layer is sprayed on top of the base glaze layer and the top layer may contain a high level of zinc oxide.

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. The cleaning system has a reservoir for holding a liquid cleaning agent having an outlet port in fluid communication with the interior space of the reservoir body; a housing to receive the reservoir; a supply conduit in fluid communication with the interior of the reservoir; a flow control device capable of controlling flow through the supply conduit; and a control system activatable by an actuator feature, wherein upon activation of the actuator feature, the control system is adapted to initiate a clean cycle by: operating the flow control device for a first period of time sufficient to deliver a dose of a liquid cleaning agent from the supply conduit to an interior space of the flush valve in a closed position, the flush valve configured for delivery of fluid to the rim inlet port, and operating the flush valve to open the flush valve to introduce flush water to carry the dose of a liquid cleaning agent through the rim inlet port into the toilet bowl.

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. The cleaning system includes a reservoir for a liquid cleaning agent, a housing for the reservoir, a supply conduit for receiving fluid from within the reservoir and delivering it to a flush valve, a flow control device capable of controlling flow of cleaning agent and a control system activatable by an actuator feature to initiate a clean cycle by operating the flow control device to deliver a dose of cleaning agent to one or more rim outlets, and operating the flush valve in cleaning actuation mode to introduce flush water to carry the dose of cleaning agent through the at least one rim outlet port into the toilet bowl at a flow rate insufficient to initiate a siphon but sufficient for cleaning the bowl.

Self-cleaning toilet assembly and system

Faucet-integrated touch-free soap dispensing systems are provided. A soap dispenser is at least partially integrated with a faucet, and includes a proximity sensor, a dispensing unit, and a soap dispensing outlet. The dispensing unit includes a soap reservoir and a pump mountable below a deck that supports the faucet, and is communicatively coupled to the proximity sensor and fluidly coupled to the soap dispensing outlet via a soap tube.
