Pinhole leaks in copper piping have become notoriously problematic. While all piping, no matter the material, are susceptible to leaks, pinhole leaks seem to be a particular trait in copper piping. While pinhole leaks may sound small, the reality is they can be a disaster for your building and your tenants.
Why are pinhole leaks in copper piping such an issue?
First of all, they were heavily used starting in the 70’s. There is a LOT of copper piping out there in Chicago area buildings. When larger leaks occur, it may be detected by sound or the immediate presence of water. Pinhole leaks may be left unnoticed for a long period, quietly causing damage behind walls, under floorboards, or in ceilings. Since generally speaking, pinhole leaks are small, building managers may not notice a big change in water usage.
What causes a pinhole leak?
Pinhole leaks in copper piping can occur for a variety of reasons, including age and corrosion. Kinks or dents can also cause pinhole leaks as can joints that didn’t have flux properly cleaned. Leaks can also occur from what is called a galvanic reaction between dissimilar metals. Many don’t realize that pinhole leaks can also be caused by filtration systems. Since these systems take natural minerals from the water, the filtered water will seek them from the copper pipes. Of course the real issue is that when pinhole leaks in copper piping begin occurring, they are likely going to continue.
What do I do when I find a pinhole leak?
At some point you may be faced with the decision to completely re-pipe, but there is an alternative. The alternative is epoxy pipe relining from Nu Flow Midwest. Pipe relining can give new life to copper pipes, sealing pinhole leaks and providing a new, smooth, interior surface that restores flow. Our epoxy lining process accommodates a variety of piping materials including galvanized steel, copper, cast iron, black iron and lead pipe and will clean and line pipe sizes down to ½ inch in diameter.
Choosing to reline copper pipes vs replacing them is much less invasive with significantly less costs in demolition and repair of walls, floors and ceilings. It inconveniences tenants less and can be accomplished quicker than replacement. Many may wonder, however, if they can “trust” pipe relining from Nu Flow newzpharmacy.com.
