What is behind the walls

Homes built in Sunny Hills from the 1950s through the 1970s were plumbed with the materials of the time, mostly galvanized steel or copper supply lines. Many have since had partial repairs, so one house can contain a mix of original pipe, newer copper and sometimes flexible plastic sections from later work.

Galvanized pipe corrodes from the inside over many decades. Rust flakes can tint the water when a tap first opens, and the narrowing bore lowers pressure. Copper ages differently; it can develop pinhole leaks, especially at bends and joints. Neither material fails on a set timetable, which is why a plumber's inspection matters more than the age of the house alone.

How to tell what you have

Look where pipe is exposed, such as under sinks, at the water heater or where the line enters the house.

  • Gray, dull pipe with threaded fittings is often galvanized steel.
  • Reddish-brown or green-tinged pipe with soldered joints is usually copper.
  • White, gray or colored flexible tubing is a plastic material added in later work.
  • A magnet sticks to galvanized steel but not to copper.
  • A mix of materials usually means past spot repairs.

What the symptom suggests

  • IfBrown water only on the hot sideThenThe water heater may be the source. Ask about flushing or tank condition first.
  • IfBrown water at first, then it clearsThenRust from galvanized pipe that sat still overnight is a common cause.
  • IfBrown water that lasts and appears suddenlyThenIt could be a disturbance on the supply side. Contact the city's water utility as well as a plumber.
  • IfSeveral pinhole leaks in a short periodThenThat pattern often leads to a whole-house repipe discussion.

Spot repair or whole-house repipe?

Spot repair or partial reroute

  • Fixes the failed section now.
  • Less disruption in the short term.
  • Leaves older pipe in place elsewhere.
  • Reasonable when the rest of the system tests well.

Whole-house repipe

  • Replaces supply lines throughout.
  • Addresses repeated leaks and rusty water at once.
  • Involves wall and ceiling openings and patching.
  • Usually requires a permit; check with the city.

How a repipe usually unfolds

Inspection
The plumber checks pipe materials, pressure and leak history and maps where the lines run.
Written proposal
Scope, materials, wall access points, patching responsibility and permit handling are put in writing.
Work days
New lines are run, often with water restored to the home at the end of each day where possible.
Inspection and patching
Any required city inspection is completed before walls are closed and patched.

Questions to ask before agreeing to repipe

  1. What did you find that makes repiping better than a repair?
  2. Which materials do you propose, and why?
  3. How many wall or ceiling openings will there be, and who patches them?
  4. Who pulls the permit and schedules the inspection?
  5. Will we have water overnight during the job?

Common questions

Is rusty water safe to drink?

Discolored water is a reason to stop and check. Run the cold tap until it clears and contact the city's water utility with water-quality questions.

Does every older home need repiping?

No. Plenty of original pipe still performs. The decision should be based on leak history, water quality and an inspection, not age alone.

What drives the cost of a repipe?

House size and layout, number of fixtures, chosen materials, how accessible the walls and attic are, and patching and permit requirements.
