If you own an older home in Chicago, there’s a good chance you have galvanized water pipes. While these pipes were once considered durable, they eventually rust and corrode from the inside out, leading to plumbing problems that only get worse over time.


What Are Galvanized Pipes?

Galvanized pipes are steel water lines coated with a layer of zinc to help prevent rust. While the zinc coating provides protection initially, it gradually wears away over the years, allowing the steel underneath to corrode.

As corrosion builds inside the pipe, it creates a rough, narrow passage for water to flow through. This can cause:

  • Low water pressure
  • Reduced water flow
  • Rust-colored or discolored water
  • Poor water quality
  • Mineral buildup inside faucets and fixtures

Eventually, the corrosion can eat completely through the pipe, resulting in leaks that may cause costly water damage to your home.

Why Galvanized Pipes Are Common in Chicago

Many Chicago homes built before the 1960s were originally plumbed with galvanized steel piping. Because these pipes have often been in service for 60 to 100 years, many are now reaching (or have exceeded) their expected lifespan.

If you’ve noticed declining water pressure, recurring leaks, or rusty water, aging galvanized pipes could be the cause.

Should Galvanized Pipes Be Replaced?

In most cases, yes. Once galvanized pipes begin to corrode internally, the problem cannot be reversed. While repairing isolated leaks may provide a temporary solution, the underlying deterioration will continue.

Replacing galvanized piping with modern materials like Type L copper piping provides:

  • Improved water pressure
  • Better water quality
  • Greater reliability
  • Reduced risk of leaks and water damage
  • A longer-lasting plumbing system
