Abstract: Embodiments of the invention provide a gasket for a fluidic seal. Some embodiments include a flush valve to a toilet tank, where the gasket has a raised center portion and lowered inner and outer portions. In some embodiments, the gasket includes a plurality of recesses, troughs or grooves. Each of the three portions of the gasket has a bottom groove that can permit deformation and increases sealing capabilities when the groove either widens or narrows. Additionally, some embodiments include an inner support ring that extends inwardly from the lowered inner portion, and can center the gasket onto the flush valve.

Abstract: An improved flush system as described herein may comprise a reservoir with a drain opening for egress of liquids disposed in the reservoir into a surrounding toilet tank. A lock mechanism is slidably received by the reservoir so that the lock mechanism is translatable between one or more fixed positions on the reservoir. In turn, translating the lock mechanism into the reservoir at increasing depths causes a size of the drain opening to be reduced and therefore adjusted.

Abstract: A leak prevention device is provided for use in operation with a fill valve with a fill valve arm in a toilet tank. The device may comprise a pivotable locking lever having a first portion positioned to pivot into and out of contact with the fill valve arm or an extension thereof. The fill valve arm affects actuation of the fill valve to modulate fluids from entering the toilet tank, wherein the pivotable locking lever is operable to contact or is capable of contacting the fill valve arm thereby prohibiting the operation of the fill valve.

Abstract: A device for preventing leaks in a toilet that comprises a fill valve operatively connected to and disposed above a float. In certain embodiments an arm is rotably connected to the fill valve such that the arm comprises a pivot. A lever is, for example, pivotally connected to the pivot of the arm and biased towards the fill valve, wherein a flush actuator causes the lever to pivot away from the fill valve. The lever may comprise a first side and a second side joined at the pivot, wherein the first side weighs less than the second side, and wherein the distribution of weight between the first and second sides of the lever causes the lever to bias towards the fill valve.
