Copper or PEX Piping? Which Is Better?

If you’re dealing with a renovation or other project requiring pipe replacement or installation, you’ll need to decide whether to use copper or PEX piping. Many older St. Louis homes contain copper piping, while newer homes are often built with PEX piping. If you own an older home, you may be wondering if you should upgrade to PEX. What are the differences between the two types of plumbing pipes? Is one type better than the other? What are the pros and cons of each? In this post, we will address all of these questions to help you decide which type is right for you.

What’s the Difference Between PEX and Copper?

Copper piping is obviously made of copper. It has been the longtime standard for plumbing and is found in many older homes throughout St. Louis. PEX piping is a newer plumbing material made of cross-linked polyethylene. In residential applications, PEX piping is commonly used in new construction or as a replacement to copper plumbing pipes. But that doesn’t necessarily mean it’s better than copper…

Which is Better: Copper or PEX Piping?

When considering whether to install copper or PEX piping, it’s important to think about the size and scale of your project, your budget, your priorities, and the local climate. Review the advantages and disadvantages of each type to decide what’s best for your particular project.
