Is Copper Used for Plumbing?

Yes. Copper is widely used for water supply lines, although alternatives like PEX and CPVC are also very common today.

Copper is strong, heat-resistant, and long-lasting. Unlike plastic pipes, it handles sunlight well, making it ideal for exposed areas or near water heaters.

However, many newer homes use PEX because it is flexible, cheaper, and faster to install. Keep in mind that while copper is durable, it can still fail due to corrosion, freezing, or poor solder joints.

It depends. Copper is rigid and highly durable, while PEX is flexible and cost-effective.

Properly installed copper can last for decades, but its lifespan heavily depends on your local water chemistry.
