Abstract

A method and device for repair and replacement of pipe broken at a junction. The device includes a coupler having a female end and a male end. The female end of the coupler has an inside diameter that will accept snugly the removed end of the broken pipe. The male end has an outside diameter that will snuggly fit into a new junction. The method and device is normally used with PVC pipe. When PVC pipe entering a junction is broken near the junction, the junction may be removed by cutting back from the broken PVC pipe and cutting the remaining pipe where it enters the junction. A new junction can be replaced with the coupler inlapping the new junction and overlapping the pipe.

Claims

1. A method of repairing a broken pipe entering a first junction, the first junction having an unbroken pipe entering the junction, the method comprising the steps of:

providing a multiplicity of similarly dimensioned sleeves, each with a female end and a male end, the male end with an outer diameter equal to the inner diameter of the first junction and the female end having an inner diameter equal to the outer diameter of the pipe, wherein the male end outer diameter is substantially equal to the female end inner diameter such that the male end of one sleeve may be inserted snugly into the female end of another sleeve;

providing a second junction having dimensions substantially similar to the first junction;

identifying the location of the break;

making a first cut of the broken pipe such that the break is between the first cut and the first junction;

making a second cut of unbroken pipe such that the cut allows the removal of the first junction;

inserting at least one male member of a sleeve into one end of the second junction and at least one male member of another sleeve into a second end of the second junction such that a sleeved junction is created that has female ends thereof;

attaching female ends of the sleeved junction to respectively overlap the first cut pipe and overlap the second cut pipe.

2. The method of claim 1 wherein the insert step includes a step of adding at least two sleeves to one end of the second junction.

3. The method of claim 1 wherein the insert step includes adding only a single sleeve to the first end of the second junction and only a single sleeve to the second end of the second junction.

4. The method of claim 1 wherein the second junction is an elbow having an angle greater than 0°

and up to and including 90°

.

5. The method of claim 1 wherein the second junction is a “

T.”

6. The method of claim 1 wherein the second junction is a cross.

7. The method of claim 1 wherein the multiplicity of sleeves come from one of the following group of sleeves, each group with the following female end inner diameters/male end outer diameters in inches:

0.852/0.84;

1.062/1.05;

1.33/1.315;

1.675/1.66;

1.918/1.9;

2.393/2.375.

8. The method of claim 1 wherein the first cut of the making step is made adjacent the break.

9. The method of claim 1 wherein the second cut of the making step is made at a distance from a point where the unbroken pipe enters the first junction, such distance being less than a length of a sleeve of the multiplicity of similarly dimensioned sleeves.

10. The method of claim 1 wherein, after the attaching step the step of adjusting takes place, the step of adjusting being the step of adjusting the overlap for optimal strength.
