Why 1950s–1980s University Place Homes Require Repiping
University Place experienced its primary residential building boom between the 1950s and 1980s. Thousands of classic ranches, split-levels, and daylight basement homes constructed during this era were plumbed with threaded galvanized steel pipe or, in the late 70s and 80s, polybutylene ("Quest") blue/gray plastic tubing.
Both materials have documented vulnerabilities that compromise water quality and structural safety:
- Internal Galvanized Corrosion: Zinc protective coatings on galvanized iron break down over 40 to 50 years. Exposed steel reacts with dissolved oxygen in water, forming heavy rust tubercles that choke internal pipe diameters from 3/4-inch down to the width of a pencil lead. This creates chronic low water pressure at showers and sinks.
- Discolored Water & Rust Flakes: First-draw morning water often flows with a yellow or reddish-brown tint, staining porcelain fixtures and laundry with iron oxide sediment.
- Pinhole Leaks in Walls & Crawl Spaces: Microscopic pitting corrosion eats through threaded pipe joints, causing silent leaks that saturate insulation and wood framing. In these situations, our leak detection service quickly identifies the failing pipe run.
- Polybutylene Micro-Fractures: Municipal water disinfectants (chlorine and chloramines) degrade polybutylene plastic acetal fittings and pipe walls, causing sudden catastrophic bursts without warning.
Comparing Modern Piping Materials: PEX-a vs. Copper
When completing a galvanized pipe replacement University Place homeowners can select between two premium modern piping solutions:
Uponor PEX-a (Cross-Linked Polyethylene)
The industry gold standard for residential repiping. PEX-a is extremely flexible, allowing lines to be snaked through wall cavities and crawl spaces with minimal drywall cutting. It is immune to mineral scale and corrosion, expands up to three times its diameter to resist winter freeze ruptures, and uses thermal expansion ring fittings that eliminate glued joints and solder fumes.
Rigid Type-L Copper
A time-tested metallic piping option offering superior rigidity, natural antimicrobial properties, and high ultraviolet/temperature resistance. Ideal for exposed basement mechanical rooms, outdoor stub-outs, and homeowners who prefer traditional metal plumbing infrastructure.
What to Expect During the Repiping Process
Repiping a home sounds daunting, but our experienced team has streamlined the process to minimize disruption to your family's daily routine:
- Preparation & Protection: We lay protective drop cloths and plastic runners across all floors and work areas before opening tools.
- Precision Access Cuts: We make small, surgically placed inspection holes in drywall beneath sinks and behind fixtures, avoiding major structural wall demolition.
- New Pipe Installation: We run dedicated hot and cold trunk lines and fixture branches from the main shutoff out to every bathroom, kitchen, laundry, and outdoor hose bib.
- Fixture Upgrades: Every repipe includes brand-new quarter-turn brass ball shutoff stops and stainless steel braided supply lines at every sink, toilet, and appliance.
- Pressure Testing & Inspection: The completed system is pressurized to 100+ PSI with air and thoroughly inspected by City of University Place building officials.
- Water Restoration: Your household water is restored at the end of each working day so your family is never left without sanitation overnight.
Protecting Your Water Heater and Fixtures
Corroded galvanized pipes dump abrasive rust grit directly into water heater tanks and fine faucet cartridges.

Repiping FAQ
For an average single-family home (2 to 3 bathrooms) in University Place, the repiping installation typically takes 2 to 3 business days. We ensure your water service is turned back on at the end of each workday so your household remains fully functional.
Yes, dramatically. When choked, corroded galvanized iron pipes are replaced with smooth-bore PEX-a or copper, internal friction is eliminated. You will experience full, consistent water pressure at every shower and faucet simultaneously.
While spot repairs can resolve an active emergency leak, partial repiping leaves the remaining corroded pipe in place to leak another day. Furthermore, connecting new copper or PEX directly to old galvanized pipe creates galvanic corrosion, accelerating failure at the union. A complete repipe is the only permanent solution.
