How heated water can damage a pipe?
When hard water is heated, a certain amount of water evaporates, causing the minerals suspended in it to precipitate. While copper, PVC and PEX pipes are more resistant to hard water buildup and corrosion, they can still get clogged or completely blocked by scale deposits.
How long does it take copper pipes to corrode?
How long does it take for copper water pipes to corrode? 68 years…. Copper goes green and turquoise after prolonged exposure to moisture. Without accelerating the process, it can actually take 20 years or more in dry climates for this patina to develop.
Why does hot water go through copper pipes?
In an effort to ensure instantaneous delivery of hot water, an oversized pump has been installed, with the result that the pipes are literally eroded away by their own contents. When water flows through a copper pipe, dissolved oxygen reacts with the copper to form a protective oxide coating.
What causes corrosion in a hot water line?
A neutral or acidic pH of water dissolves the copper oxide barrier of pipes, making them vulnerable to accelerated corrosion, resulting in pinhole leaks. In addition, the higher your water temperature is, the faster oxidation happens, which corrodes metal, therefore putting hot water lines at higher risk for corrosion.
What can cause a water pipe to corrode?
You may find several of the factors that exacerbate corrosion to be surprising. For example, some of the cleanest drinking water in the United States also has a chemical makeup that is extremely hard on pipes, and some of the most popular drain cleaning products are exceptionally harsh and known to cause pipes to corrode.
How does pH affect the corrosion of copper pipes?
If your pH is 8 or higher (meaning more alkaline and not acidic), a film of copper oxide will form on the inside of your pipes, slowing or minimizing corrosion. However, if your water pH is neutral or acidic, the copper oxide barrier dissolves, leaving your copper pipes vulnerable to accelerated corrosion.

How can you tell if your water heater has corrosion?
Once water leaks past the seal and makes contact with the steel and copper connections, corrosion begins. Galvanic corrosion will dissolve the steel pipe threads within the copper fitting connected to it. A simple visual check of the pipes and fitting at the top of your water heater should reveal any signs of corrosion.
