The disclosure is directed to a flapper system and a flapper system kit that is compatible with both 2″ and 3″ flush valve seats. In some embodiments, the flapper system is configured to enable a user to select either a 2″ or 3″ flush valve seal for the flapper system. In some embodiments, the flapper system includes a pivot that enables sealing of a flat flush valve seat or an angled flush valve seat. In some embodiments, the flapper system includes one or more adjustable window assemblies that control a fluid flowrate within an internal portion of the flapper system to control buoyancy. In some embodiments, the flapper system includes an adaptor that converts a 2″ valve into a 3″ valve.

Omni configured flapper systems for various flush valve sizes and methods of retrofit

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

Some embodiments include a fluid control system with an outlet valve assembly, an inlet valve assembly including a venturi inlet valve, and an actuator coupled to the inlet valve assembly. In some embodiments, the actuator can enable a user to control a flush volume of fluid control system. Some embodiments include a moveable float positioned in a chamber of the outlet valve assembly, where the chamber includes a variably-sized upper portion with a volume that is based at least in part on a variable position of the moveable float in the chamber. Some embodiments include a adjustable control valves coupled to an outer surface of the outlet valve assembly and the inlet valve assembly. Some embodiments also include a bellows positioned in and coupled to the variably-sized upper portion. In some embodiments, the bellows are fluidly coupled to the venturi inlet valve and at least one of the control valves.

Fluid control system and method

Washer

A toilet seal for sealing between a plumbing fixture discharge and a waste drainpipe outlet is described. The toilet seal comprises a flange member having an inwardly extending flexible lip. A flexible sleeve extends downwardly from the flange member. The toilet seal further includes a compressible member having an upper surface disposed adjacent to a lower surface of the flange member. The compressible member further has a lower surface and a plurality of ridges extend downwardly from the lower surface of the compressible member.

Universal height absorbing toilet seal

Some embodiments include an assembly with an inlet housing enclosing an outlet housing that includes an inlet. The outlet housing includes an outlet port and a channel or aperture coupled to an outlet and apertures coupled to atmosphere. A moveable or flexible member is positioned in the inlet housing coupled to the outlet housing, and can deform, flex and/or move based on a flow and/or pressure of fluid from the inlet. Based on the flow and/or pressure of fluid from the inlet, the moveable or flexible member can reversibly move from a first position to a second position and/or from a second position to a first position. The first position is characterized by the moveable or flexible member being coupled to, proximate to, sealed to the aperture, and the second position is characterized by the moveable or flexible member being moved away from the aperture.

Pneumatic lost motion/binary device system and method

Some embodiments include a valve assembly with a metering seal including a main channel including regions with a first diameter and regions with a second diameter, where the first diameter is smaller than the second diameter. Some embodiments include a stem positioned in the metering seal extending from at least a first end of the metering seal to a second end of the metering seal. In some embodiments, the stem has a fluted section positioned between two non-fluted sections, where the diameter of stem in the fluted section is smaller than the diameter of the stem in the non-fluted sections. Some embodiments include a first and second flow channel extending across at least a partial width of the metering seal, where the first flow channel is positioned at the first end of the metering seal, and the second flow channel is positioned at the second end of the metering seal.

Balanced activation force and bistable valve system and method

The system includes a fluid valve with a modular and/or replaceable fluid control assembly that requires maintenance over a product life of the fluid valve. The modular and/or replaceable fluid control assembly includes at least one portion including a setting or presetting configured and arranged to control fluid flow behavior in the fluid valve. The setting or presetting is useable to control fluid flow in the modular and/or replaceable fluid control assembly after an upgrade or replacement of at least a portion of the modular and/or replaceable fluid control assembly. Further, the setting or presetting enables the modular and/or replaceable fluid control assembly to retain the fluid flow behavior following one or more upgrades or replacements of one or more portions of the modular and/or replaceable fluid control assembly.

Modular fluid valve

A fill valve system with a float nested in a container connected to the fill valve and a siphon device passing water out of the container into the toilet tank, with the siphon device having an air vent dimensioned such that: (i) tank refilling is delayed until after the flush valve closes; (ii) the fill valve is not turned on by small leaks in the tank; and (iii) the fill valve turns off when it encounters large leaks in the tank.

Siphon activated valve

Some embodiments include a fluid valve assembly with an outlet base dimensioned to be positioned through a drain in a fluid tank, and a float assembly including a moveable float. The moveable float can form a fluid-tight seal at a first end when the moveable float is coupled to the outlet base, and a flow opening when the moveable float is at least partially decoupled from the outlet base. Some embodiments include a housing positioned with the moveable float, where the housing encloses a suction device coupled to a moveable piston. Some embodiments include an actuable diaphragm positioned in the outlet base, and a compressed air tube or passageway coupled to one side the actuable diaphragm. In some embodiments, the actuable diaphragm is configured and arranged to be actuated by compressed air to move the moveable piston.

Discharge valve system and method

A fluid valve with a modular and/or replaceable fluid control assembly is disclosed, and is configured and arranged to require maintenance over a product life of the fluid valve. The modular and/or replaceable fluid control assembly includes at least one portion including a setting or presetting configured and arranged to control fluid flow behavior in the fluid valve. The setting or presetting is useable to control fluid flow in the modular and/or replaceable fluid control assembly after an upgrade or replacement of at least a portion of the modular and/or replaceable fluid control assembly. Further, the setting or presetting enables the modular and/or replaceable fluid control assembly to retain the fluid flow behavior following one or more upgrades or replacements of one or more portions of the modular and/or replaceable fluid control assembly.
