What Is A Pinhole Leak?
Pinhole leaks can occur in copper pipes. Copper pipes have been one of the most commonly used plumbing materials for almost sixty years, due to their ability to resist most forms of corrosion. There is one form of corrosion that they are vulnerable to, however: A localized copper corrosion called pitting corrosion.
Pitted corrosion tends to focus on a very small area of the pipe. It works from the outside inward. It opens up a small leak in the pipe, known as a pinhole leak. They’re called pinhole leaks because the leaks are often the size of pinheads. They are usually only large enough to leak one or two droplets of water at a time.
What Can Cause A Pinhole Leak?
There are all sorts of reasons why a pinhole leak might materialize. Here are some of the most common causes of pinhole leaks:
- Faulty Installation
- Age of pipes
- Chemistry of local soil
- Poor chemistry in the copper itself
- Water treatment chemicals hasten the breakdown process
Why They Can Be Dangerous
What makes pinhole leaks so dangerous is that they’re subtle. Most plumbing problems are fairly obvious: Clogs and ruptures often display large symptoms that are hard to ignore. Pinhole leaks are so small and easy to overlook, however, that there’s no way to tell if you have one without examining the pipe. Since the leaks aren’t usually caught as they happen, this gives them time to inflict water damage over a wide area, drop by drop.
It’s easy to think that pinhole leaks are harmless: After all, what harm could a few drops of water do? The answer is: PLENTY. Left unchecked a pinhole leak could do extensive damage to your home, including:
- Damage to plaster and sheet rock
- Damage to flooring
- Damage to walls
- Damage to insulation
- Mold and mildew growth
- Corrosion in other parts of your plumbing system
