Seattle Pipe Replacement: Galvanized vs Copper vs PEX

Seattle homeowners deciding between copper and PEX for galvanized pipe replacement should know:

Copper: The traditional choice in Seattle; proven 50+ year lifespan; more expensive material; some Seattle plumbers prefer it for its proven record in Pacific Northwest water chemistry. Current copper supply prices have risen 30-50% since 2020.

PEX (Cross-linked Polyethylene): Now the dominant choice for whole-house repiping in Seattle; faster to install; flexible (easier to route around Seattle older home framing); freeze-resistant (important for Seattle homes with unheated crawl spaces); costs 20-40% less in labor than copper. PEX-A (Uponor) is considered the highest quality PEX variant. Seattle plumbers have broadly adopted PEX for repiping projects.

Don't use: CPVC in Seattle older homes - brittle with age and poor freeze resistance for Seattle crawl spaces.
