Abstract: A toilet system including a bowl and a tank configured to hold water and air and deliver water to the bowl. The tank includes a water inlet and outlet. A valve having a seal pivots between an open position and a closed position where the seal closes the outlet. A lever positioned outside of the tank pivots to push the valve out of the closed position and towards the open position such that the outlet is opened and water flows out of the tank into the bowl. The valve rotates to the open position as water flows from the tank until the weight of the seal causes the valve to pivot back to the closed position. A plunger extends into the tank and applies a force that pushes the valve away from the closed position to the open position.
Abstract: Various methods and systems are provided for external float extensions. In one embodiment, an external float extension includes an external adjustment rod configured to affix to a quick flush float of a dual flush assembly and an external float configured to be positioned on the external adjustment rod. In another embodiment, a dual flush assembly includes a quick flush float, an external adjustment rod affixed to the quick flush float, and an external float positioned on the external adjustment rod.

Abstract: A system for microbially deactivating items. The system includes a circulation system for circulating a microbial decontamination fluid through a deactivation chamber that forms a part of the circulation system. A container for holding items to be deactivated is provided. The container has a sealable cavity in which the items to be deactivated may be placed, and at least one valve element that is movable between an open and a closed position to regulate fluid flow into the cavity. An actuator in the deactivation chamber is operable to move the valve element to an open position when the container is disposed within the deactivation chamber, wherein the cavity within the container is in fluid communication with the circulation system when the valve element is in the open position.

Abstract: A pressurized water closet flushing system for flushing a toilet includes a water vessel having at least one opening for receiving water. A fill tube and a discharge tube extending into the vessel are secured to the vessel. A modular assembly cap including an intake and an actuator covers the opening. The fill tube remains secured to the vessel when the assembly cap is removed from the vessel.
Abstract: A pressure assist toilet includes a gravity flow bowl, a gravity flow tank, and a thin walled pressure tank. The thin walled pressure tank is selectively configured to have a rectanguloid shape for insertion into the gravity flow tank and having strengthened areas to enable said thin walled pressure tank to be pressurized to about 20 PSI. The thin walled pressure tank is charged with a predetermined volume of water at about 20 PSI, and the charge is released from the thin walled pressure tank to the gravity flow bowl.
Abstract: A flush control device for controlling the flush operation of a flush toilet having a cistern, a feed water control mechanism fluidly coupled to a water supply pipe and a flush water control mechanism fluidly coupled to one end of a flush pipe, the opposing end of which is connected to a toilet bowl. The flush control device includes a float coupled to the feed water control mechanism for operating the mechanism to stop water supply as the float reaches a predetermined water level. At the end of the flush operation, the descent of the float will operate the flush control mechanism to end the flow of water from the cistern to the flush pipe and operate the feed water control mechanism to supply water into the cistern again.
