When you think about serious plumbing issues, what comes to mind? Do you think about clogs, large leaks, or even ruptures? Many homeowners are of the belief that the worst plumbing issues are the big ones, those that cause the most flashy and immediate damage. This actually isn’t the case. Some of the worst plumbing issues are the ones that you likely won’t even notice until it’s too late. Read on to find out more about one of the most damaging plumbing issues you’re likely to encounter: the pinhole leak.

The Cause of Pinhole Leaks

Copper pipes have been the major plumbing material for almost 60 years, due to their resistance to most forms of corrosion. However, there is still one kind of corrosion that still affects copper pipes: pitted corrosion. Pitted corrosion tends to be focused in a very small area of the pipe, and works from the outside inward. This will open up a small leak in the pipe, known as a pinhole leak. Pinhole leaks are only large enough to leak one or two droplets of water at a time. However, on a long enough timeline that’s all they need to cause significant damage.

Why Pinhole Leaks are Dangerous

The reason that pinhole leaks are so much more dangerous than other plumbing issues is because they’re subtle. Most larger plumbing issues have equally large symptoms to warn homeowners. A pipe rupture will result in the loss of water flow, while a clog backs up through the drain. With a pinhole leak, though, the problem itself is so small that there’s no way to tell if you have one without examining the pipe. This gives the leak time to inflict water damage over a wide area, one drop at a time. The first time that many homeowners become aware of a pinhole leak is usually when they notice a large section of their wall has become rotted out.

The only way to catch pinhole leaks in time to mitigate the damage is to have your plumbing inspected at least once a year. If you haven’t had your plumbing inspected in a while, call The Trusted Plumber. We provide plumbing services throughout Phoenix, AZ.
