What triggers a pin-hole leak in a copper water line?

A pin-hole leak is a small to medium sized hole that increase start
in piping producing a spray or stream of water to shoot out. In many instances these leaks build because of the pipe eroding from within. There are various of reasons as to why a leak happens. Most of the primary components that cause a leak include age of pipes, your cities water pressure, the number of minerals found in your water, exactly how the water pipes are set up (i.e. joints, corners, turns etc.), what time of year it is, and ways in which the plumbing was hooked up.

Most often the water leaks occur towards the water main inside the house. They can occur close to the water main as this is the location where the water pressure is at it’s highest inside your home. Similar to how water after some time can cut deep into rock creating erosion. It also can rust within your pipes. It slowly rusts the inside of the tubing until it consequently gushes through the pipes.

All around the US in many different locations and regions, you can find significant water pressure with numerous minerals within the water. These points in addition to the average structure age of your home around 20-40 years of age shows that there’s a large volume of pinhole leak problems in recent times. Increased substance content in water can result in several water line challenges. Anything from water heaters to faucets and water pipes are influenced by the mineral deposits. Using a softener in your water supply doesn’t help considerably either. Using a softener in water does not eradicate many of the minerals which have been contained in water.

Pin Hole Leaks in Pipe Joints
Almost all the variables that cause pin-hole leaks are unavoidable. We can’t modify the mineral content or temperature of the water entering your home. Many leaks materialize at or near the pipe joint. In other words the place where the pipe connection is. This could be an elbow fitting or even a coupling. Any time water passes by the pipe joint you will find turbulence. Water whirls and spins as it passes through the fittings. Avoiding this is quite inescapable. The disturbance triggers the water to deteriorate the water pipe from the inside out.

Corrosion in Fittings
Whenever a leak arises at a fittings it may be as a result of 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.
