Remove the Old Flapper

What happens here

With the tank empty, remove the old flapper. This particular Kohler flapper is not a standard type that simply slides off. It features hard plastic clips that attach to small 'tongues' on the flush valve. To remove it, use one finger on each side of the flapper to gently pull upward. Listen for a 'click' as the clips disengage from the tongues. Repeat on the other side, and the entire flapper assembly should pop off. Exercise caution to avoid breaking the plastic tongues, as doing so would necessitate replacing the entire flush valve, a more extensive repair.

Goal: Detach and remove the worn-out flapper mechanism from the toilet tank.
