What is a Pinhole Leak?

A pinhole leak can occur in any copper plumbing, be it residential or commercial. Pinhole leaks are caused by a certain type of corrosion, known as pitting corrosion. While copper pipes in general are extremely resistant to corrosion, this type of corrosion is a type that scientists are still unsure what the exact cause it (which is one of the reasons it is so hard to prevent in plumbing). It is suspected that formaldehyde in the air is a leading factor.

Formaldehyde is a naturally-occurring organic compound that is produced by all life forms as a part of cell metabolism. Formaldehyde is also a chemical that is found in hundreds of household products, from engineered wood products that are commonly used in the construction industry to build our homes to use in vaccines and personal care products. It is quite effective as a disinfectant, and it acts as a preservative to medicines that are used to kill bacteria. Your plumber in Orlando notes that because of these reasons, it is extremely difficult to rid formaldehyde from the air and our environment, leading to this type of copper pipe erosion.

Corrosion of copper pipes turns them gray. Once corrosion sets it, the pipes are weakened, and tiny holes open up, which is where the name comes from. Once these pinholes form, water begins to leak, which can then seep into your drywall, flooring, and ceilings, causing damage to the structure of your home and wood rot. Other damage that pinhole leaks can cause is mold growth. The slow drip of the pipes creates a moist environment where black mold and mildew love to thrive. Mold and mildew can have a negative effect on your health.


Once you call in your plumber in Orlando, Choice Plumbing, to determine if you have a pinhole leak, they will first inspect your pipes. If a pinhole leak (or more) is found, you have various options, depending on the severity of the leak itself.

Repair the Small Leak(s) Itself

Repairing small leaks is obviously the preferred plumbing solution because no one really wants a major plumbing repair job that your Orlando plumber has to perform. This is a great option if your copper pipes are newer (less than 20 years old is considered new for copper piping since they last so long). Your plumber in Orlando finds a pinhole leak in a joint, elbow, or tee in your piping. These are isolated areas that are easy plumbing repairs. Or, the pinhole leak(s) is only located in one specific piece of copper piping that is easily replaceable. Often, epoxy is used to line the particular problematic pipe. This forms a seal against the entire length of the pipe, preventing further leakage. This fix usually lasts between 40 and 60 years, so probably until it is time to replace your piping in your home or business.

Repipe Your Entire Home

Now before you balk, there are good reasons to replace your entire piping. If the pipes in your home are more than 20 years old, it probably about time you thought about whole-house pipe replacement anyway. As your pipes age, they become weaker, making them more prone to leaks. Major leaks can cause major damage in a very short amount of time — much more costly damage than replacing all of your pipes will cost you. If you are getting multiple leaks frequently and they are in different areas of your home or office’s piping, then this is a sign of extensive pitted corrosion in your plumbing piping. It is much more cost effective to replace all of your piping rather than keep calling us every few months for plumbing repairs. Your Orlando plumber, Choice Plumbing, offers repiping services to stop the leaks for good.


Install a Water Filtration System

One contributing factor to leaks in pipes is hard water. Hard water leaves behind mineral deposits that can collect in your pipes. Not only can these restrict the flow of water, but they can also act like sandpaper, rubbing against your pipes as water flows through. If you have hard water, installing a whole-house water filtration system can prevent this mineral accumulation from occurring. Your Orlando plumber, Choice Plumbing, can test your water for you to determine if it’s hard.

Lower Turbulence in Your Pipes

If you have an abundance of minerals in your water, they can speed through your pipes at high velocities, which hit the sides of the piping hard. In copper piping especially, this can contribute to pinhole leaks as this constant bombardment wears out the lining of your pipes (especially in piping that causes the water to change directions, such as fittings and elbows). You can lower the velocity of the water in your pipes (speeds of between 5 and 8 fps is recommended).

Your Orlando plumber recommends that you can make sure your pipes are the right size for your water needs. Smaller pipes increase the bombardment rate, which wears down your piping more. Signs of inadequate sized pipes are banging noises or frequent clogs. This is something your professional plumber can help you assess.

Finally, you can check your pipe fittings to make sure they are not too close together. Pipe fittings serve to change the direction of the flow of your water in your home or business. They are usually found where pipes join together as well. More spacing between fittings reduces the turbulence in your pipes. All of these preventative measures will help to prevent pinhole leaks.

Invest in Regular Plumbing Inspections by Your Plumber in Orlando

Because pinhole leaks are so difficult to detect, it is highly recommended by your Orlando plumber to get regular piping inspections completed on your home or business. This is the best way to prevent problems with pinhole leaks as professional plumbers can detect these small holes when they occur and patch them up before any major damage occurs.
