When it is time to replace your home's aging plumbing, you will likely face a choice between two primary materials: PEX and Copper. Here is what Oregon homeowners need to know.

The Case for Copper

Copper has been the gold standard in plumbing for decades. It is incredibly durable, resistant to UV light (so it can be used outdoors), and naturally bacteriostatic, meaning it inhibits bacterial growth. However, copper is expensive, requires more labor to install, and can be susceptible to freezing and bursting if not properly insulated during cold Oregon winters.

The Case for PEX

PEX (cross-linked polyethylene) has become the most popular choice for modern repiping. It is highly flexible, meaning fewer fittings and a faster, less destructive installation process. It is also significantly less expensive than copper and expands slightly if frozen, making it more resistant to bursting. PEX cannot, however, be used outdoors where it is exposed to direct sunlight.

Which is Right for Your Home?

For most residential repipes in the Portland Metro and Columbia County areas, PEX is the recommended choice due to its cost-effectiveness, durability, and ease of installation. Copper remains a premium option for specific applications.
