How to Tell if You Have Galvanized Pipes in Orange County: 3 Quick Checks

Galvanized pipe is dull gray steel. It is also not copper-colored or plastic. A magnet sticks to it because it is iron. Scratch off the dirt with a key, and galvanized stays dull gray. Also, EBMUD says galvanized pipe was commonly used before the 1960s.

Here is how to check. These tests come from the East Bay Municipal Utility District (EBMUD) and its galvanized pipe page:

  1. Look at the pipe. Check exposed lines under sinks, in the garage, and near the water heater. Gray metal pipe may be galvanized, but copper looks orange-brown, and plastic is usually white, black, or blue.
  2. Try a magnet. A magnet sticks to galvanized pipe. It does not stick to copper or plastic.
  3. Scratch it. First, wipe off paint or dirt. Then scratch the pipe with a key or screwdriver. Galvanized stays dull gray. If it turns shiny silver and feels soft, it may be lead, so call a plumber.

That is one utility’s guidance for its own area. Still, the tests work the same way anywhere. Not sure what you found? A repipe specialist can confirm it during a free in-home estimate.

What Warning Signs Mean Your Galvanized Pipes Are Failing?

The main warning signs are rust on the outside, rust on the inside, and dark brown water. Low water pressure is another. Any one of them means the zinc coating has likely worn away. As a result, the steel underneath is rusting, and the pipe is wearing out.

These are the signs to watch for:

  • Rust on the outside. Orange or brown flaking on exposed pipe is the easiest sign to spot, because you can see it.
  • Rust on the inside. Look at the cut end of a pipe or an old fixture. Rusty buildup inside means the pipe is corroding from within.
  • Dark brown or rusty water. Water that turns brown after it sits overnight is a common sign.
  • Low water pressure. EBMUD says old, corroded galvanized pipes can cause low pressure and discolored water.

In our experience, a galvanized pipe that is already rusting can fail without much warning. So don’t wait for a leak to act. Want to know what each kind of rust means? Read our guide to rusty galvanized pipes in Orange County.

What Should You Do if You Find Galvanized Pipes?

If you find galvanized pipes, plan to replace them. So rust or dark brown water means a repipe specialist should look at your whole system. In our experience, replacing the pipes before they leak costs less than repairing water damage later.

Here is what to do next:

  1. First, take photos of any rust or flaking pipe.
  2. Next, note when the water turns brown, such as in the morning.
  3. Skip patching one spot, because the rest of the pipe is just as old.
  4. Then schedule a free in-home estimate.
