What causes a pinhole water leak?

A pinhole leak is a small hole that develops in a pipe, causing a mist or stream of water to shoot out. In most cases, these leaks develop due to the pipe being eroded from the inside out.

There are a number of factors that cause these leaks to occur. Some of the main factors that lead to a leak include:
•Age of plumbing.
•Your municipality’s water pressure.
•The level of minerals found in your municipality’s water.
•What season it is.

How does a pinhole water leak develop?
In most cases, the leaks occur near the water main inside the house, because this is where the water pressure is the greatest in the home. Just like how water can cut deep into rock over time, creating things like the Grand Canyon, it also can erode the inside of your pipe.
Once the pipe has eroded, water eventually breaks through. For example, an elbow may develop a leak at the bend. When a leak occurs, you should have it checked by a professional plumber. Most of the factors that cause pinhole leaks can’t be avoided. We can’t change the mineral content or temperature of the water coming into the home. Most leaks occur at or near a joint where a connection is. This could be an elbow or a coupling. When water passes by a joint, turbulence is created. The water swirls and spins as it passes through the joint, causing the water to erode the pipe from the inside out. When a leak occurs at a joint, it may be due to the installer failing to ream out the copper tube after cutting it. When copper tubing is cut with a tubing cutter, it gets pinched as it’s being cut. This creates a lip on the inside of the tube.  This lip can exaggerate the amount of turbulence that occurs at the joint. To prevent this, the tube must be reamed by the plumber when it is installed.


How do you repair a pinhole water leak?
If you get a pinhole leak, what should you do? You’re going to have a plumbing professional repair the leak. Not because I want to make a sale, but because it is the law in all modern codes. Sure you can try it your self, but most times things go wrong and the problem is worse. Believe me leave it to the pros. Less headaches and problems. Besides sometimes your insurance company covers the repair cost.
