Help, I have a three year old house and the shower drain flange in the second story bath broke. The drain is a style simalar to the Oatey PN42044 although the treaded portion of the upper flange on mine is a slightly smaller diameter and has a grate attached with 2 stainless steel screws. I have contacted the builder and the plumber that installed the shower and have gone to all of the retail and Wholesale plumbing outfits in my area and have not found the correct shoer drain. I am looking for the exact replacement so that I can repair the shower with out cutting the ceiling and wall below the shower. Any and all suggestions would be appreciated.
