How To Repair PVC Pipe Fracture

Most common cause of PVC pipe failures.

PVC pipe fracture is often caused by extreme stress on the pipe wall. PVC pipe is specifically designed with high pressure applications in mind. However, the stress that usually causes this type of tear is caused by human error. Dropping the pipe and breaking into pieces, for example. However, errors in the manufacturing process leave the pipe vulnerable to fracture in inherently weak spots as well. Weak spots are known as weak extrusion knit lines. Weak knit extrusion lines are the other cause of PVC pipe fracture. In extreme cases, the split will run down the entire length of the pipe. As long as the pipe does not curl up on itself, Tech-Patch repair is feasible. The Tech-Patch will serve to strengthen the weakened area of the pipe and provide a full high pressure seal along the crack. Tech-Patches are by far the only affordable full seal repair option for large PVC pipe fractures.

PVC Pipe Fracture

PVC Pipe Fracture Repair Steps:

1) Rough the PVC around the PVC fracture with sandpaper.
2) Drill a hole at each end of the crack so that internal pressure will not cause the crack to expand.
3) Clean with any cleaner that will not leave a residue. Dry thoroughly.
4) Spray the Activator/Accelerator (AA) on the prepped area. Let the AA dry.
5) Apply the SI Black to the Tech-Patch with continuous circles EXCEPT on diagonal corners. Paying special attention to having the adhesive reach the edges.
6) Grab the diagonal corners, apply tension.
7) Press the Tech-Patch to the fractured area on the PVC.
8) Use the glue squeegee to apply firm pressure to the Tech-Patch from the center out.
9) Bond the diagonal edges to the PVC with the SI Black. Spray with AA.
10) Apply a bead of the SI Black to the perimeter of the Tech-Patch. Spray with AA.
11) Visually inspect.

Instructions for repairing a hole or crack in PVC pipe:

Step by step.


1) Rough the PVC around the problem area with sandpaper.
2) Drill a hole at each end of the crack so that internal pressure will not cause the crack to expand.
3) Clean with any cleaner that will not leave a residue. Dry thoroughly.
4) Spray the Activator/Accelerator (AA) on the prepped area. Let the AA dry.
5) Apply the SI Black to the Tech-Patch with continuous circles EXCEPT on diagonal corners. Paying special attention to having the adhesive reach the edges.
6) Grab the diagonal corners, apply tension.
7) Press the Tech-Patch to the problem area on the PVC.
8) Use the glue squeegee to apply firm pressure to the Tech-Patch from the center out.
9) Bond the diagonal edges to the PVC with the SI Black. Spray with AA.
10) Apply a bead of the SI Black to the perimeter of the Tech-Patch. Spray with AA.
11) Visually inspect.

If your problem is a crack, drill a hole at each end of the crack so that internal pressure will not cause the crack to expand. Your Tech-Patch is bonded onto the PVC and will not come off. Note: PVC is a co-polymer, but you do not need our patented Polymer Bonding Process in order to bond a Tech-Patch to the PVC.
