Abstract: A fluid flow control adjuster device controls fluid flow ratios when placed in-line with a tube that runs from a toilet fill valve to the overflow tube of a flush valve. The device comprises an adjuster having an adjuster body with an inlet and an outlet. The body includes an adjuster knob and a receiver gap, which is a gap between a body rotation stop and another edge at a top surface of the adjuster knob. A key is also provided which can be inserted between the body rotation stop and the edge of the adjuster so that the installer can dial in the correct percentage of fill. The key is a hub-like planar structure that matches the curvature of the receiver and includes a plurality of key fingers with each finger including indicia that correlate to settings for selecting a proper toilet bowl refill range.

Abstract: A method, system and software product provides a comprehensive toilet repair product selector guide. A search engine is made available to consumers, retail sellers and others in an “on-line” format. Such a method, system and software product will provide the user with prompts and guidance for diagnosing toilet problems, improving toilet performance and realizing water savings. The method, system and software product of the present invention would be accessible using mobile encoding technology, personal digital assistants (such as “smart phones” and the like) and other personal computing devices.

Abstract: A plunger of the present invention is a generally hollow structure having a number of integrally-formed sections disposed between the top and the bottom. The plunger has a conical upper portion having an increasing diameter moving downwardly from the top of the plunger toward a central portion. There is a pleated bellows section at the central portion of the plunger. Extending downwardly from the central portion is a lower conical portion having a decreasing diameter moving from the central portion toward the bottom. The top includes an opening for a handle and the bottom comprises an opening to the interior cavity of the plunger. In the preferred embodiment of the invention, the plunger is formed of a resilient rubber-like material that is capable of being deformed and then returning to an un-deformed shape, the material having memory. The plunger can be used in standard or specially-configured toilet bowl outlets.

Abstract: A tank to bowl sponge gasket is provided for use with a flush valve used in the drain hole of a toilet tank, the tank sitting above the throat of a toilet bowl. The flush valve comprises a flange above the bottom wall, a lower externally threaded portion that extends through the drain hole and an internally threaded lock nut which complements the lower threaded portion of the flush valve, a tank seal disposed between the flange and the tank wall, and the gasket is disposed between the lower threaded portion of the flush valve, the lock nut and the tank wall and the throat of the toilet bowl. The gasket has a generally L-shaped upper portion with a circumferential outer surface, a circumferential inner surface and a bottom shelf, a lower portion comprising a circumferential inner surface and an inwardly tapered outer surface, and a circumferential trim line.

Abstract: An improved fill valve has a pivot valve body that is pivotally suspended immediately below a float housing and is movable between two positions. In a first position, the pivot valve body blocks the flow of water from the float housing. In a second position, the pivot body allows the flow of water from the float housing. The pivot valve body has two top compartments, each separated from the other by a wall. The first compartment retains an amount of water in it. The second compartment functions as a water flow restriction apparatus and includes an upwardly-extending member for sealing off a check valve that is disposed within the bottom of the float housing. A pressure compensating drip emitter allows water to trickle into the float housing at a very slow rate. The emitter comprises a labyrinth structure having a plurality of serpentine pathways formed in its outer surface.
