ABSTRACT:
A replacement water closet tank for toilets, comprising, a tank means formed of a thin, rigid, high-impact strength plastic, including, a generally-rectangular, open-topped tank; a cover designed to overlap and fit flush with the exterior walls of the tank; interlock means, such as flat tabs formed on the interior of and parallel to the lower rim of the cover and spaced from the cover by perpendicularly-disposed flat spines to form generally T-shaped structures which fit into slots in the upper edge of the tank to clamp the upper edge of the tank between the overlapping portion of the cover and the tabs; and a generally-rectangular, thin, pliable plastic liner having overall dimensions sufficiently less than those of the tank to fit within the tank and form an air space between the tank and the liner and an upper rim extended outwardly a sufficient distance to contact the sides of the tank and be pressed against the tank to form an air-tight seal. The flush valve assembly and ball cock assembly are mounted through holes in the liner and holes in flat-topped inward depressions in the bottom of the tank and in a manner to bind the liner to the tank, and bolts, for mounting the tank on a toilet bowl are mounted through holes, drilled at the side, in selected ones of a plurality of inward depressions in the bottom of the tank, with the head of the bolt in sufficient proximity to the liner that flexing the liner downwardly will frictionally hold the bolt head during mounting.
