 Image Number 3 for United States Patent #5182819.
A kit that includes a universal flapper and water saver valve stop for the fluid outlet of sanitary flush tanks utilizing a flat, thin, doughnut shaped gasket mounted on alternate supports, wherein the use of one support allows the doughnut shaped gasket to maintain its relatively flat configuration as in standard flapper valves, and the use of the alternate support stretches the doughnut shaped gasket to form a truncated cone, the dimensions of which closely follow those of standard ball valves, and the support structure for the valve stop includes at least two connecting devices for alternately connecting the valve stop to the different types of connecting assemblies found in standard flush tanks.
