What are the causes of a pin-hole leak in a copper water line?

A pin-hole leak is a small to medium sized hole that build up start
in piping resulting in a misting or steady stream of water to shoot outward. In most cases these pipe leaks build as a result of water line being eroded from within. There are a number of explanations that explain why a leak develops. Among the major elements that lead to a leak may include the age of your home, your cities water pressure, the total amount of minerals present in your water supply, how pipes are put together (i.e. elbows, bends, turns etc.), what time of year you are in, and the way the piping was hooked up.

In most cases the leakages develop close to the water main in your home. They can occur around the water main as this is the location where the water pressure is at it’s highest in the home. Just like how water ultimately can cut deep into rock creating erosion. It also can deteriorate in the interior of your pipes. It slowly erodes the interior of the water line until it ultimately bursts through.

Around the US in many different locations and cities, you can find excessive water pressure with numerous minerals in the water. These things in addition to the average structural age of the home around 25-40 years old indicates that we have a large level of pinhole leak calls recently. Higher organic mineral content in your water supply might cause multiple plumbing problems. Everything from water heaters to faucets and water lines are influenced by the mineral deposits. Using a softener in your water doesn’t help substantially either. Softening water doesn’t dispose of many of the minerals that happen to be present in the water.

PinHole Leakages in Pipe Fittings
Most of the conditions that cause pinhole leaks are unavoidable. You cannot alter the mineral levels or temperature of the water entering into the home and property. A number of leakages materialize at or near the pipe joint. Basically where a pipe connection is. This might be a pipe elbow or even a pipe attachment. Anytime water goes by one of these fittings you will find turbulence. The water swirls and revolves while it goes through the joint. Preventing that is fairly unavoidable. The disturbance can cause the water to deteriorate the pipe from the inside out.

Corrosion in Fittings
When a leak develops at a fittings it may possibly be due to the installer failing to ream out the copper after cutting it. When a copper pipe is cut with a pipe cutter it gets pinched as it’s being cut. This creates a lip on the inside of the pipe. This lip can exaggerate the amount of turbulence that occurs at the joint. Often a pipe that has multiple holes generally occurs due to the installer not reaming out the pipe after cutting it.
