PEX

Flexible, fewer joints, resists freeze splitting better than rigid pipe, and is common in repipes routed through attics. It must be protected from UV light.

Copper

Rigid and long-lived, but more expensive and more labor to install. Under slabs it can develop pinhole or abrasion leaks.

Cost

See the repiping cost guide for published ranges for each.
