Means for covering the flange of a waste water strainer
DCFirst Claim
1. In combination with a fluid compartment having a bottom witha waste water strainer mounted in said bottom, said strainer having a cylindrical wall with a bottom edge surrounding a cylindrical opening extending through the bottom of said compartment, and a flange extending outwardly from a level above and adjacent said cylindrical opening and positioned on the bottom of said compartment:
- a waste water insert comprising a wall with a cylindrical first portion and a cylindrical second portion with a conical portion therebetween, said cylindrical first portion having a diameter greater than a diameter of said cylindrical second portion, said wall surrounding a cylindrical bore and having an upper end, and a flange on said upper end extending outwardly from said cylindrical bore;
the wall of said insert being spaced from cylindrical wall of said strainer wherein said cylindrical first portion being closer to said cylindrical wall of said strainer than said cylindrical second portion;
and the cylindrical second portion of said insert receiving a resilient ring that engages said cylindrical wall of said strainer.

Abstract
A waste water insert has a cylindrical wall surrounding a vertical cylindrical bore. A horizontal flange extends outwardly from the upper end of the wall and has a lip formed on its outer periphery. The horizontal flange of the waste water insert is super-imposed over the horizontal flange of a waste water strainer located in a bathtub, sink or the like. The cylindrical wall of the insert extends downwardly through the cylindrical wall of the waste water strainer with the two walls being spaced from each other by virtue of the cylindrical wall of the insert having a smaller diameter than that of the strainer. One or more grooves are within the cylindrical wall of the insert and receive resilient rings that engage the cylindrical wall of the strainer.
