How Do Pipes Corrode, And Why Is This A Big Deal?

Posted on: 28 September 2018

Pipes are one of the longer-lived components of a home's plumbing system. However, they do not last forever. One of the biggest problems that arise in pipes is corrosion. Why does corrosion happen, and why is it such a big deal? Read on to learn!

Why does corrosion occur?

Corrosion happens when various minerals in the water react with the metal that comprises the pipe. It is more common in galvanized steel pipes, which were commonly used in homes prior to 1960. (Once plumbers realized galvanized pipes had so many problems with corrosion, they stopped using them.) It can happen in copper pipes, too, particularly if the water has a more acidic pH. 

If you are noticing white deposits or weird markings on your faucets, then you probably have corrosion in your pipes too.

Why is corrosion a big deal?

Corrosion is a major issue because it can cause sudden leaks and burst pipes. A pipe may develop a small hole in it, leading to water leaks and mold growth where the water leaks out. Or the pipe may freeze, and since it is weak from corrosion, it may burst -- leading to intense flooding that causes thousands of dollars in water damage.

What should you do about corrosion?

If you suspect that your pipes may be corroded, your best bet is to call a plumber and have them replace the pipes in question. They can send a camera down into the pipe to assess the nature of the corrosion before recommending replacement or repairs. While you might fear the expense of replacing your pipes, note that it is often less than the cost of repairing your home after a burst pipe!

If your pipes that are experiencing corrosion are relatively new, you should also look into why the corrosion is appearing. If your water is too acidic, you may need to install a water treatment system to adjust the pH of your water as it enters your home. Or you may need to choose PEX or plastic pipes over copper ones to avoid corrosion in the future.
