Why Historic & Older Pullman Properties Need Repiping
Understanding internal pipe tuberculation, corrosion pinholes, and the advantages of modern materials.
Homes built before 1970 throughout Pioneer Hill and near Military Hill were originally plumbed using threaded galvanized steel pipes. While galvanized steel has high tensile strength, zinc coatings degrade after 40 to 50 years of contact with municipal water.
Once the zinc layer dissolves, raw iron reacts with dissolved oxygen and hard minerals, causing severe internal rust accumulation known as tuberculation. The interior bore of a half-inch pipe gradually narrows until it resembles a clogged artery, severely choking water flow. Furthermore, homes built with copper lines in the 1970s and 1980s frequently suffer from pitting corrosion and pinhole slab leaks due to local water chemistry.
Telltale Indicators Your Home Needs Repiping:
- Brown or Yellow Water on Startup: Water running rusty or discolored when you first turn on faucets after sitting overnight.
- Severe Water Pressure Drop: Water flow dropping to a trickle in the shower whenever someone flushes a toilet or runs a sink.
- Recurring Pinhole Leaks: Experiencing multiple leak repairs within a 12-month period in different areas of your home.
- Metallic Taste or Odor: Water exhibiting a sharp iron or copper taste that affects drinking and cooking quality.
- Visible Corrosion on Exposed Pipes: White chalky deposits, flaking green patina, or bubbling rust visible on basement pipes.
PEX-a vs. Traditional Copper
Cross-Linked Polyethylene (PEX-a): Highly flexible, seamless tubing that weaves through wall cavities without cutting large swaths of drywall. It will never corrode or pit, dampens water hammer noise, and can expand slightly during winter freezes without bursting.
Rigid Copper: Traditional metal with long history, but higher material cost, vulnerable to mineral scale friction, rigid joints requiring open soldering torches, and susceptible to sub-zero freeze ruptures.
