Whole House Repiping in Burien, WA
Low water pressure, discolored rust water, and recurring pinhole pipe leaks are unmistakable symptoms of deteriorating supply plumbing. Washington Plumbing – Burien specializes in whole-house repiping, replacing corroded galvanized steel and defective polybutylene with premium Uponor PEX-a or USA-made copper across King County.
Why 1940s–1960s Burien Homes Require Repiping
A substantial portion of Burien's residential housing stock was built during the post-war building boom. These homes were plumbed with galvanized iron pipes that have now reached the end of their operational lifespans.
Galvanized Steel Tuberculation
Over 50 to 70 years, the internal zinc coating inside galvanized pipes dissolves. Bare iron oxidizes, forming jagged mineral scale (tuberculation) that chokes the interior diameter down to the size of a drinking straw.
Homeowners experience severe water pressure loss whenever a toilet flushes while someone is showering.
Rusty, Metallic-Tasting Water
As internal pipe flaking accelerates, tap water turns red, brown, or yellowish after sitting overnight. Rust flakes clog faucet aerators, shower cartridge valves, and toilet fill mechanisms.
Corroded pipes stain porcelain sinks, ruin laundry fabrics, and damage domestic water heating elements.
Recurring Wall & Slab Leaks
Once an older pipe system develops its first pinhole leak, the pipe walls have thinned throughout the entire plumbing network. Patching a single leak usually causes water pressure to rupture the next weakest point.
Whole-home repiping permanently eliminates the threat of ongoing drywall water damage and toxic mold development.

Modern Repiping Materials: PEX-a vs. Rigid Copper
We install only premium, code-approved plumbing materials backed by manufacturer warranties, ensuring reliable water delivery for generations.
Uponor ProPEX (PEX-a) Cross-Linked Polyethylene
Uponor PEX-a represents the gold standard in modern residential repiping. Manufactured using the thermal Engel method, PEX-a has thermal shape memory that makes it virtually freeze-damage immune. If frozen, the pipe expands and returns to original size without bursting.
The ProPEX expansion connection system creates solid mechanical seals that cannot pull apart. Flexible tubing snakes cleanly through wall cavities with minimal drywall incisions.
- Completely immune to mineral corrosion, rust, and scale buildup
- Exceptional acoustic dampening eliminates noisy water hammer clangs
- 25-year manufacturer material warranty on Uponor systems
- Significantly faster installation with fewer wall openings than copper
Rigid Type-L USA Copper Piping
For homeowners who prefer traditional metal supply piping, we install heavy-duty Type-L hard-drawn copper lines with lead-free silver soldered or pro-press mechanical fittings.
Copper provides naturally bacteriostatic interior surfaces and exceptional fire resistance. We ensure all new repiping connects smoothly to your water heater and exterior hose bibbs.
