Abstract
A push-type drain stopper is usable in a drain pipe that has a pivot rod port surrounded by a stub by sealing a rod that protrudes into the pipe through the stub. The stopper is pressed transversely into engagement with the rod, which is an anchor. The drain pipe has a drain flange that seals around a drain opening in a sink. If the flange becomes worn and unsightly or if one desires to change a color scheme for the sink, a cap that has a diameter greater than the drain flange hides the drain flange from sight. A retrofit kit includes the drain stopper, pivot balls sized to fit different pop-up drain assemblies, a rod that passes through the ball into the drain pipe, and a wing nut fixed to an end of the rod for tightening the rod against a stub cap.
