So what is a copper pinhole leak?

Let’s face it. Copper isn’t perfect. It might appear strong on the outside but it could be on verge of breaking from the inside due to corrosion. There are many reasons for this to happen varying from water characteristics and properties, water pressure or incorrect installation. No leak present just after installation doesn’t always mean that installation was done correctly. Unfortunately it’s impossible to see whether installer did good job without taking pipes apart.
