US 2015/0089736 A1 · BATHTUB DRAIN AND OVERFLOW KIT

Abstract

A bathtub drain and overflow fitting kit is provided having a drain fitting, an overflow fitting and/or an adapter fitting, for connecting the bathtub drain and overflow openings to the household waste plumbing. The overflow fitting has a ball and socket connection between its inlet and outlet. Preferably, the overflow fitting has an abutment member which limits the range of angles created by the joint socket and joint ball within a range of angles to about 10°. The kit includes a gasket having a first sealing portion, a second sealing portion, and a tapered sealing portion between the first and second sealing portions, and is configured so that the same gasket may be used at the drain opening or the overflow opening. The drain and overflow fittings have at their inlets retaining features that interengage matching retaining features on the gasket to hold during installation.
