Complete Copper Pipe Repair Guide

The Tech-Patch Repair System. A Tech-Patch with a Starter Kit is required to repair a copper pipe.

The key to repairing a pin hole leak in copper pipe:

As always, surface preparation is critical. Please follow steps 1, 2 and 3. Cut a Tech-Patch to fit. If the problem is just a small pinhole leak, then a one inch square patch will be sufficient. Our XT Tech-Patches have a burst pressure rating of 120 psi, so will be able to handle the pressure in any home or building. Then follow the remaining steps in the instructions above.

The key to repairing a crack in a copper pipe:

With any crack, we strongly recommend drilling a small hole at each end of the crack. Minimal pressure is required to extend a split in a pipe or tank. The drilled holes stop expansion. As always, surface preparation is critical. Once the surface is prepped, cut an XT Tech-Patch to fit and follow the remaining instructions.

Copper pipe repair can be an arduous task. In the past there were really only three options, expensive total pipe replacement by a plumber, soldering or a so called “easy fix” solution that required you to buy SharkBite couplings, depth tools, pipe cutters and more. Luckily, we have developed a complete copper pipe repair guide for all pipes, including all types of copper; Type L, Type M, Type K, DMV and copper alloys. The answer that we have developed after years of fielding problem repair questions, is the Tech-Patch Repair System. We offer a lifetime guarantee for the life of the Tech-Patch, as well as a money back satisfaction guarantee, that comes standard with all of our products.

The Miracle Material

and The Miracle Solution For it:

Tech-Patches are made of a revolutionary material, FVMQ or fluorosilicone. This poly patch has remarkable resistance to aging, weather, chemicals, water, oil, gas and more. In the past, there wasn’t much you could do with this material, due to the composition. Now in conjunction with our patented Bonding Poly Process, you can easily and permanently bond FVMQ Tech-Patches to any substrate, including all types of copper. Every facet of the TPRS repair system from the bond, to the Tech-Patch, to the Tech-Bond itself, is impervious to common chemicals, weather, water, oil, gas and will not decrease in strength with age. Just as important, the cost of the Tech-Patch Repair System is just a fraction of the cost of total pipe replacement or similar repair options.

Accelerated Aging

Preventive and curative properties:

Tech-Patches can tackle any type of repair problem you may have, from cracks, holes, pinholes and even wall thinning and pipe degradation. Wall thinning and wall degradation are Type A repairs. The Tech-Patch can not only repair leaks, but actually help restore and protect, thin and corroded pipes. Type B repairs are through wall; holes, cracks, etc. Accelerated aging tests conducted for the American Water Works Association, conclusively prove that the Tech-Patch not only restores the copper, but aids in extending the life of the pipe as well. The picture below was taken after accelerated aging. As you can see, the steel is extremely rusted and corroded. The patch is not. In addition, the area of the pipe underneath the patch, appears virtually pristine. While the example picture below is with steel, it is an extremely important issue with copper as well.

Most Common Repair Issue with Copper Pipes

Pitting Corrosion:

By far the most common problem with copper pipes are leaks which occur as a direct result of pitting corrosion. Pitting corrosion is most likely to cause numerous pinhole leaks throughout the affected area. Don’t let the word pinhole fool you. While pinholes are small, do not underestimate the damage they can cause. Drywall damage and harmful mold buildup are just a few of the problems, this seemingly insignificant damage could cause. The older your pipes, the more often you should perform regular inspections to catch a small problem and fix it, before it becomes a large problem.

Regular inspections recommended

and the solution complete with kit recommendations either way:

While it is definitely best that you perform regular inspections, the Tech-Patch Repair System can both help prevent an issue before it even starts or fix one that it is already a problem. It does not matter if you are taking preventative measures for areas that look ripe for corrosion or fixing current issues, the application process is the same. The patch comes prepared and treated with our Poly Prep Adhesion Promoter. This is a vital step in the Bonding Poly Process. Copper as a metal does not need the adhesion promoter, but it will be necessary that the surface is dry and that any corrosion or film be sanded off the pipe. The kit comes with everything necessary to do the repair, including sandpaper. A commercial Tech-Patch or above is recommended due to pressure. The commercial patch is rated at 120 psi. The average psi for all residential indoor pipes is 60 psi. Along with the Tech-Patch, we recommend the Starter Kit or above. The poly kits are not necessary for this particular application as the patch already comes primed with our Poly Prep Adhesion Promoter. We do recommend having it on hand for other types of repairs, as so much is now made out of new space age plastics that are normally impossible to bond.

Complete Copper Pipe Repair Steps:

Flexible permanent home copper pipe repair system.

1.Rough the damaged surface area with 60 or 80 grit sandpaper.
2. Polish the same area with a 400 or 600 grit sandpaper.
3. Clean the surface with any cleaner that does not leave a residue.
4. Spray the damaged surface area with the Activator/Accelerator (AA).
5. Let the AA dry.
6. Apply a SI adhesive to the precut Tech-Patch EXCEPT for diagonal corners.
7. Pick up the patch by the diagonal corners. Apply tension.
8. Press onto the copper pipe. Grab will occur in 5 – 8 seconds.
9. Use the glue squeegee to apply firm pressure on the patch from the center out.
10. Apply a bead of the SI adhesive to the perimeter. Spray the bead with the AA.
11. Visually inspect for any problems.
