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 conventional waste water strainer located in a bathtub, sink or the like. The lip at the outer perimeter of the flange of the insert fits over the outer periphery of the horizontal flange of the waste water strainer to center the insert on the strainer. The cylindrical wall of the insert extends downwardly through the conventional 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. The conventional cylindrical wall of the strainer extends below the cylindrical wall of the insert, and has a lower circular edge. One or more spring clip elements having upturned ends are suspended from the cylindrical wall of the insert, with the upturned ends abutting the lower circular edge of the conventional strainer cylindrical wall.
