Whole House Repiping in Poulsbo, WA

Why Older Poulsbo Homes Require Complete Repiping

Many homes built in Poulsbo before the 1970s – notably in Downtown Poulsbo (Front Street) and vintage neighborhoods near Liberty Bay – were originally plumbed with galvanized zinc-coated steel pipes. Decades later, internal zinc coatings have eroded away, leaving raw iron exposed to oxygenated municipal drinking water.

Over 40 to 60 years, internal oxidation creates heavy rust and mineral crusting (tuberculation). What started as a 3/4-inch interior pipe diameter is frequently restricted to the width of a pencil. Homeowners experience severe water pressure loss whenever multiple fixtures run simultaneously, rust-colored or yellow water in the mornings, metallic taste, and pinhole leaks that trigger sudden plumbing emergencies.

Material Comparison: PEX vs. Copper

When repiping a residential property, selecting modern materials ensures lasting reliability:

• Cross-Linked Polyethylene (PEX-A): Today's premier choice for residential repiping. PEX is flexible, allowing continuous pipe runs from central manifolds through wall cavities without elbows or buried joints behind drywall. It expands up to 300% without splitting, making it exceptionally resilient during winter cold snaps. Furthermore, PEX is impervious to acidic water pitting and mineral scale.
• Type L Rigid Copper: A traditional, premium metal option favored for exposed utility room runs and water heater manifolds. Copper offers proven structural rigidity and antimicrobial properties, though it is more labor-intensive to install and remains susceptible to aggressive soil pitting or chemical pinholing over time.

What to Expect During a Professional Whole-House Repipe

Many homeowners postpone repiping out of fear of invasive wall demolition. Our streamlined process is engineered for minimal disruption:

1. Detailed System Design: We map water distribution runs, sizing main trunk lines and fixture branch feeds according to Uniform Plumbing Code fixture unit tables.
2. Surgical Wall Openings: We make precise, minimal cuts in drywall behind vanities, inside closets, and along basement or crawl space access points.
3. New Pipe Installation: PEX supply lines are routed cleanly to every bathroom, kitchen, laundry fixture, hose bibb, and water heater connection.
4. Dedicated Main Shutoff & Fixture Valves: We install a modern quarter-turn brass ball valve at the main entry point and install new stainless steel quarter-turn angle stops beneath every sink and toilet.
5. Hydrostatic Testing & Sign-Off: The new piping system is pressure-tested under city inspector oversight before clean drywall patching and cleanup.
