What is a pinhole leak in a copper water line?

A pin-hole leak is a small hole that increase in a pipe resulting in a misting or stream of water to shoot outward. Normally these leaks build up due to the water line eroding internally. There are various of reasons that explain why a leak occurs. Among the major variables that cause a leak include age of pipes, your towns water pressure, the amount of minerals found in your water, the way the water pipes are set up (i.e. joints, corners, pipe bends etc.), what season you are in, and just how the piping was hooked up.

Usually the leakages develop at the water main inside the house. They occur around the water main because this is exactly where the water pressure is the greatest inside your home. Exactly like how water as time passes can cut deep into rock creating erosion. It also can deteriorate in the interior of your water line. It slowly erodes the inside of the tubing until it eventually bursts through.

Across the US in various states and cities, there may be substantial water pressure with lots of minerals within the water. These conditions as well as the usual structural age of the house between 20-40 years old suggests that there is a large range of pinhole leak phone calls recently. Elevated mineral content in the water could potentially cause various water pipe complications. Everything from water heaters to faucets and water pipes suffer from the excess minerals. Conditioning your drinking water doesn’t help significantly either. Using a softener in water doesn’t take away most of the minerals which can be contained in water.

PinHole Leaks in Pipe Joints
A lot of the conditions that induce pin-hole leaks can’t be avoided. You cannot modify the mineral content or water temperature entering the house. Almost all water leaks appear at or near a joint. Basically where the connection is. This can be a right-angle fitting or maybe a pipe attachment. The moment water passes by the pipe joint there is always disturbance. Your water whirls and rotates while it goes through the pipes. Avoiding this is considerably inescapable. The turbulence may cause water to erode the water pipe from within.

Erosion in Pipe Fittings
Whenever a leak comes up at a joint it is usually because of 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.
