A flapper flush valve assembly includes a pair of laterally movable mounting arms which may be adjusted to vary a width therebetween to accommodate overflow tubes of different sizes. The flapper valve assembly is coupled to pivot members connected to an overflow tube. Mounting ears on the pivot members may include projections to provide spacing between the rotating mounting arms and adjacent sidewall of a toilet tank, thereby preventing jams.
A dual flush button assembly includes a unitary button with a full flush surface and a partial flush surface. Pressing the partial flush surface moves the button linearly to active a partial flush. Pressing the full flush surface rotates the button to activate a full flush. An extension member beneath the button is coupled to a link of a dual flush valve. The extension member is moved farther when the full flush surface is engaged. The button is configured to pivot with respect to a housing when the full flush portion is engaged.
