Abstract

A waste water insert has a wall surrounding a vertical 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 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.

Claims

1. A waste water insert adapted to be associated with a strainer that includes a strainer wall having an inner surface, comprising:

a flange;

an insert wall extending from said flange, said insert wall having a continuous cylindrical outer surface that has a first end corresponding with said flange and a second end spaced from said first end, wherein the distance between said first end and second end is constant, said insert wall having an outer diameter that is less than the inner diameter of the strainer wall, such that said insert wall is adapted to be spaced from the strainer wall;

an enlarged seal interconnected to said outer surface of said insert wall, said enlarged seal having a length that corresponds with the distance between said first end and the second end of said insert wall, wherein a first end of said enlarged seal is positioned adjacent to said first end of said insert wall, and a second end of said enlarged seal is positioned adjacent to said second end of said insert wall; and

said enlarged seal includes an upper portion spaced from the strainer wall, a lower portion spaced from the strainer wall, and a mid portion that is adapted to contact the strainer wall when the waste water insert is positioned within the strainer, said mid portion having an outer extent that is substantially equal to the diameter of the inner surface of the strainer wall, whereby said waste water insert is positioned within and removed from the strainer without the need of tools.

2. The device of claim 1 wherein said enlarged seal is made of a resilient material.

3. The device of claim 1 wherein said insert wall is devoid of grooves.

4. The device of claim 1, wherein said lower portion of said enlarged seal possesses a tapered surface.

5. The device of claim 1, wherein said flange includes a lip that is adapted to cover a portion of an outer edge of a flange of the strainer that is interconnected to the strainer wall.

6. The device of claim 1, wherein said flange has an outer edge that comprises a downwardly extending lip.

9. The device of claim 1 wherein said enlarged seal is in close contact with said insert wall.

10. The device of claim 1 wherein said enlarged seal forms an elastomeric layer of said insert wall.

7. A waste water insert adapted to be positioned within a pipe, the pipe having an inner surface, consisting essentially of:

a flange;

a cylindrical wall extending from said flange, said cylindrical wall having an unbroken outer surface that has a first end corresponding with a lower surface of the flange and a second end spaced from said first end, wherein the distance between said first end and second end is constant, said cylindrical wall having a diameter that is less than the diameter of the pipe inner surface, such that said cylindrical wall is adapted to be spaced from the inner surface of the pipe when the waste water insert is positioned in the pipe;

a resilient seal interconnected to said cylindrical wall, said resilient seal having a proximal end and a distal end that coincide with said first end and said second end of said cylindrical wall, said resilient seal also having a tapered surface at said distal end, said resilient seal having a portion located above said tapered surface that is adapted to contact the inner surface of the pipe, said portion having an outer extent that is substantially equal to the diameter of the inner surface of the strainer wall; and

wherein said flange of said waste water insert is adapted to be positioned adjacent to an upper end of the pipe, wherein said cylindrical wall extends downwardly into an opening defined by the pipe, and said resilient seal is adapted to be positioned within a space provided between an outer surface of said cylindrical wall and the inner surface of the pipe, whereby said waste water insert is positioned within and removed from the pipe without the need of tools, such that when said waste water insert is positioned within the pipe, said proximal end and said distal end of said resilient seal do not contact the inner surface of the pipe.

8. The waste water insert of claim 7, wherein said resilient seal has a cylindrical inner surface that resiliently grips said insert wall.
