Pinhole Leak In Faucet: Reasons And How To Fix It?

When people talk about any threat to their plumbing system, they are usually thinking about leaks. Leaks can do severe damage to a plumbing system.

The biggest problem with leaks is that sometimes they are very small, and hard to detect.

If you are wary about leaks, this article is for you. Here we will talk about how you can detect pinhole leaks in faucets, and how you can fix them.

What Causes Pinhole Leaks?

A pinhole spill is a consequence of what is known as “pitted corrosion”, where a pipe starts to erode from the outside. It only influences copper pipes, which are ordinarily impervious to any remaining sorts of corrosion.

Pinhole spills are generally tiny – simply big enough to allow a periodic trickle of water. However, that sluggish dribble can cause a considerable amount of harm whenever left alone for quite some time.

Nobody truly knows for specific why copper pipes tend to corrode in such an uncommon manner.

Many people assume it to be something in the air that damages the pipet. Up to this point, be that as it may, the EPA has been not able to indisputably distinguish the reason for pinhole spills.

How To Fix Faucet Pinhole Leak?

Now that you know what pinhole leaks are and why they come up, let us look at how you can fix pinhole leaks in the faucet.

  • Fix Using Epoxy Putty

Since pinhole leaks are very small, the easiest way to repair them is using epoxy putty.

The most efficient tool is an epoxy putty stick. This tool combines resin and hardeners.

In order to use an epoxy putty stick, you have to first tear off the amount of putty required and then knead it by hand.

Soon after that, the putty will turn to a uniform color, at which point you should be pushing it into the pinhole.

After some time, it will cure and harden, filling and then sealing the pinhole. These repairs are long-lasting but they are not permanent.  

  • Using Pipe Repair Tape

One of the downsides of epoxy putty is that it will struggle to create a bond with the pipes once the water pressure cannot be turned off. The higher the pressure, the less is the chance of a successful repair.

When this happens, a good alternative is waterproof pipe repair tape. These tapes are made from silicone that is self-fusing. When it is stretched and wrapped around a pinhole, it will form a solid rubber band over the area where the leak is coming from.

Like the epoxy putty, waterproof repair tapes can be reinforced with a pipe repair bandage using an added layer of protection.

  • Using a Pipe Repair Clamp

With pipe repair clamps, you will get another very straightforward method of fixing your pinhole leak. This tool consists of a metal sleeve with a flexible pad of rubber inside.

Sometimes, you will see a small hole in your bathroom faucet. You can use the pipe repair clamp to fix this issue. Initially, place the clamp over the portion of the pipe that requires repair.

Next, tighten the screws, and you will see that it bolts down and covers the entire pipe. The leak has been sealed.

There are certain limitations to this tool as well, such as these can only be used on straight section repairs. If the leak is in some other place, the covering or repair will not be as effective.

  • Replace the Pitted Pipes

Sometimes, pinhole leaks can be quite a frequent occurrence. Regular leaks can be a sign of extensive pitted corrosion that has been present in your pipes for a long time.

If this is the case for you, it is better for you to replace damaged sections of the faucet as the high levels of corrosion can lead to much more serious issues than just pinholes.

The older your pipes, the more likely is that they need replacing. Many people follow this method for sealing a pinhole leak.
