Abstract: Disclosed are a toilet flapper and associated methods. In one representative embodiment, a flapper is provided having an upper side and a sealing side, the sealing side including a sealing surface. A dome protrudes from the sealing side at a middle of the sealing surface. Also, an opening of the dome is positioned in the upper side of the flapper. A float is employed with the flapper.

Abstract: A gutter cleaner comprises a float portion and a stem portion. The float portion comprises a float piece that typically has a size larger than the downspout opening of a gutter in which the gutter cleaner is installed. Accordingly, the float will not flow down or become lodged in the downspout. The float piece is made of materials or in a manner such that the float piece will be raised within the gutter when water flows there through. The stem portion typically is attached to the float portion and extends downwardly into the downspout of the gutter. As rainwater flows into the gutter and down the downspout, the water will raise the float while the stem portion will remain extending downwardly into the downspout. The flow of the water agitates the stem and the float regions of the gutter cleaner. This agitation action reduces the buildup of small twigs and pine needles at the downspout region, thereby facilitating the flow of debris and water down the downspout and out of the gutter.

Abstract: A buoyant outlet closure, or `flapper` in the preferred embodiment, is vented at a selectively predetermined time in the water closet flushing cycle, causing the flapper to become non-buoyant and to drop and to close the tank outlet, effecting a premature termination of the flushing cycle, and saving the volume of water remaining in the tank. The venting is controlled by turning the externally mounted operating handle in one direction. When the operating handle is turned in the opposite direction, essentially all the water is discharged from the tank, effecting a full flush cycle.

Abstract: A flush and refill device for use with a tank having an outlet and a means for refilling the tank with the liquid. The device includes a pair of floats and a guide means for guiding the floats for vertical movement. One of the floats serves as a valve for the tank outlet and the float controls operation of the refilling means.

Abstract: A flush valve control apparatus for selectively closing, at the option of the operator, the flush valve of a flush toilet is disclosed. The apparatus includes a control member which is located such that it can selectively push against the flush valve which opens and closes the outlet pipe of a flush toilet. The control member which is normally in a non-control relationship with the flush valve is attached by a hinge to the standpipe such that it may be rotated downwardly until it contacts the top portion of the valve. A rod is pivotally attached to the control member at one end and slidably attached to a line at its second end. The link is attached to the handle of a trip lever, such as is normally found in conventional toilets. On forcing the trip lever downward by rotating the handle in a direction opposite to that for flushing, the link slides along the rod until it meets a stop.

Abstract: A water-saving float-to-inlet valve adapter device or modifier which may comprise original equipment or a replacement for a conventional substantially transversely directed attachment arm conventionally provided and connecting a buoyant float and an inlet valve into a toilet flush tank, with the modifier or adapter functioning to effectively modify the normal position of such a buoyant float, and correspondingly the normal maximum height of the water level in the flush tank at the end of each refilling operation, when the adapter effectively causes the inlet refilling valve to be turned off, whereby to in effect greatly reduce the amount of water contained in the toilet flush tank at the end of a refilling operation following each flushing operation and consequently reducing the amount of water utilized in each flushing operation, which in one preferred form, is selectively adjustable.
