Abstract

A cleanout extension adaptor for insertion into a cleanout extension construction in a plumbing arrangement. The cleanout extension adaptor includes a cylindrical body with a small, thin lip on the top for seating on the top of a cleanout extension. The cleanout extension adaptor has internal threads which accommodate a threaded plug that is contained within the confines of the cleanout extension when installed. The cleanout extension adaptor permits cutting the cleanout extension so that it is even with the surrounding surface. When the plug is inserted into the cleanout extension adaptor, the cleanout extension and plug are substantially even with the surrounding surface. This avoids cutting out or altering the surrounding surface in any way.

Claims

1. A cleanout extension adaptor for use in the flush mounting of a cleanout extension, comprising:

a cylindrical body having an axial throughbore and an external diameter that is slightly less than the internal diameter of the cleanout extension;

a radially outwardly extending lip on the top of said cylindrical body for extending over and engaging the top edge of said cleanout extension for positioning and supporting the cleanout extension adaptor in position when inserted into said cleanout extension;

means for affixing said cleanout extension adaptor to the interior of said cleanout extension; and

means on the interior of said cleanout extension adaptor for seating a sealing plug so that said sealing plug is substantially even with the area surrounding the top of the cleanout extension.

2. A cleanout extension adaptor according to claim 1 wherein internal threads are provided on said cleanout extension adaptor for mating with external threads on the sealing plug.

3. A cleanout extension adaptor according to claim 2 wherein the bottom of said cylindrical body is tapered to avoid obstructing a cleanout tool when the cleanout tool is pulled through the cleanout extension.

4. A cleanout extension adaptor according to claim 1 that is formed of a hard plastic.

5. A cleanout extension adaptor according to claim 1 wherein said lip is thin enough to be peeled off the cleanout extension adaptor after the cleanout extension adaptor is fixed in position on said cleanout extension.

6. The method of installing and sealing a cleanout extension so that it is substantially even with the surrounding surface without disturbing the surrounding surface, comprising the steps of:

cutting the cleanout extension to a height that is substantially level with the surrounding surface;

selecting and mounting an adaptor in the top portion of said cleanout extension to receive a sealing plug within the confines of said cleanout extension;

selecting said adaptor to have a generally tubular configuration with an internal threaded bore and an outer diameter to fit within the bore of the cleanout extension and to have an outwardly extending lip for engaging and overlapping the cut end of the cleanout extension for providing a finish to said cut end and for positioning and supporting said adaptor; and

inserting a threaded sealing plug into the cleanout extension so that the top of the sealing plug is substantially level with the surround surface.

7. A cleanout extension adaptor for use in the flush mounting of a cleanout extension, comprising:

a cylindrical hard plastic body having a top edge and a bottom edge with an external diameter that is slightly less than the internal diameter of the cleanout extension;

an outwardly extending annular lip having a thickness of about one-thirty second of an inch on the top edge of said cleanout extension adaptor for holding and positioning the cleanout extension adaptor, wherein the bottom edge of said cylindrical body is tapered to avoid obstructing a cleanout tool when the cleanout tool is pulled through the cleanout extension;

thread means on the interior of said cleanout extension adaptor for seating a threaded sealing plug so that said sealing plug is substantially even with the area surrounding the top of the cleanout extension.
