4 Ways to Avoid Pinhole Leaks in Copper Pipes

4 Ways to Avoid Pinhole Leaks in Copper Pipes

Of all the things that could go wrong with your plumbing—probably the least of your concerns are small pinhole leaks in your copper pipes. However, these tiny punctures can lead to huge issues in your home. Not only do they negatively impact water pressure, but you could also be stuck with a surprisingly large bill. Save yourself some stress and money by understanding these four ways to avoid ​​pinhole leaks. 

How to Prevent Pinhole Leaks In Your Pipes

Internal corrosion causes pinhole leaks in copper pipes. This means that the leak occurs from the inside out, where internal corrosion causes a breach in the exterior of the pipe. To help avoid this issue, follow our four tips below. 

1. Know the Age of Your Pipes 

Copper pipes that are over 20 years old should at the very least be inspected. But truthfully—it’s better to replace your pipes early than to wait for something to go wrong. 

2. Decrease the Water Velocity

The speed at which water and the minerals found in water travel can cause damage to your copper pipes. To avoid pinhole leaks, call a licensed plumber and have them check to ensure your water velocity isn’t too high. 

3. Inspect the Pipe Fitting 

If you didn't know, fittings are the pieces that connect straight pieces of pipe. When installed correctly, fittings help water move through your home easily. However, an installation error can cause water turbulence and a breakdown. Check the fitting of the copper pipe for pinhole leaks or have it checked out by a professional plumber. 

4. Invest in a Water Softener 

Did you know that about 85% of homes have hard water? Your home is likely one of them, which means there’s a higher level of minerals such as calcium and magnesium running through the pipes. These minerals are fine to drink but cause additional wear and tear on your piping. A water softener can help eliminate or balance the mineral count in your water, so it will be gentler on the pipes.

Signs of Pinhole Leaks 

Keep an eye out for these signs to help your small leak not lead to bigger problems. 

Increased Water Bill 

Has your water bill been higher than usual? Unless your water-using habits have significantly changed recently, it could be due to a pinhole leak in your copper pipes. Monitor your water bill for any oddities. 

Low Water Pressure 

While waiting on your water bill, you should monitor your water pressure. Even the smallest of leaks affect water pressure. 

Visible Damage 

One of the easiest ways to spot a problem with your pipes is to check under and around them. If you notice water damage—there’s likely a leak.

Like checking for water damage, the presence of mold and mildew is easy to spot. As water leaks undetected behind your walls, it creates the perfect environment for mold and mildew growth. 

Dripping Noises

Have you noticed a dripping sound but can’t figure out where it's coming from? It could be a small pinhole leak in the copper pipes. 

Pipe Discoloration 

As you may know, copper has an indistinguishable reddish-brown color. If the exterior of your copper pipes looks brown, green, or blue, you likely have a leaking problem that’s causing the copper to oxidize. 


Similar to discoloration, if you’re noticing moisture or wetness on the exterior of your pipes, there's a problem. It could be caused by the leak itself or condensation from the leak.
