Whole House Repiping in Olympia, WA
If your Olympia home suffers from persistent low water pressure, rusty or discolored tap water, pinhole leaks behind walls, or deteriorating galvanized steel or polybutylene piping, Washington Plumbing provides comprehensive whole-house repiping. We replace failing water lines with durable, modern PEX-a or copper piping.
Why Older Olympia Homes Require Repiping
Olympia boasts beautiful historic craftsman homes, mid-century properties, and vintage bungalows in districts like South Capitol and the Eastside. However, plumbing materials installed decades ago have reached the end of their operational lifespans.
Galvanized Steel Tuberculation
Plumbing installed prior to the 1960s predominantly utilized threaded galvanized iron pipes. Over decades of exposure to municipal water, the internal zinc coating dissolves, allowing bare iron to react with oxygen.
This creates rust nodules and mineral scaling that severely choke the internal diameter of the pipe, reducing flow to a trickle when multiple fixtures run.
Pinhole Leaks in Thin Copper
Homes constructed from the 1970s through the 1990s often feature thin-walled copper pipes. In certain localized soils or with water velocity wear, copper lines suffer from pitting corrosion.
Microscopic pinholes develop inside wall cavities, dampening structural framing and fostering mold growth before becoming visible. If you notice signs of hidden moisture, our leak detection team can pinpoint the exact breach.
Defective Polybutylene (Quest) Pipe
Commonly installed in 1980s and 1990s suburban developments across Thurston County, grey polybutylene plastic piping reacts negatively to municipal water disinfectants.
Plastic acetal fittings micro-fracture and pipe walls become brittle, leading to catastrophic sudden bursts that insurance underwriters frequently refuse to cover.

PEX vs. Copper: Selecting the Best Pipe Material
We install both advanced cross-linked polyethylene (PEX) and traditional Type L rigid copper based on your home architecture.
PEX-a (Cross-Linked Polyethylene)
Modern PEX-a tubing is the gold standard for residential whole-house repiping. Highly flexible, PEX-a can be fished through wall cavities, joists, and crawl spaces with minimal drywall cutting, preserving your home's historic interior trim.
PEX is completely immune to mineral scale buildup and acidic pitting corrosion, expands if exposed to freezing temperatures without bursting, and eliminates "water hammer" pipe banging. It offers exceptional performance at an accessible investment level.
Commercial-Grade Type L Copper
For homeowners who prefer traditional metal piping or require exposed water lines in unfinished historic basements, Type L rigid copper provides proven structural rigidity and unmatched UV resistance.
Copper is naturally antimicrobial, impermeable to airborne contaminants, and fully recyclable. We solder and pro-press copper lines with exacting precision, adhering to all City of Olympia plumbing codes.

For an average single-family Olympia home with 2 to 3 bathrooms, the physical plumbing replacement takes approximately 2 to 4 days, followed by municipal inspection and drywall patch completion.
