Why Galvanized Pipes Fail in Orange County: Rust, Corrosion, and When to Replace Them

Why galvanized pipes fail in Orange County comes down to one thing: the zinc coating wears off. Once it does, water sits on bare steel, and steel rusts. Below, we explain how that happens, how long it takes, and when to replace the pipes.

Watch: what causes galvanized pipes to fail.

Why Galvanized Pipes Fail in Orange County: The Short Answer

Galvanized pipe is steel with a zinc coating that protects it from water. Over time, the zinc wears off. Then water sits on bare steel, and steel rusts. The rust narrows the pipe, discolors the water, and eventually eats through the pipe wall. That is how galvanized pipes fail.

What Is Galvanized Pipe, and What Does the Zinc Do?

Galvanized pipe is iron or steel pipe coated in zinc. The East Bay Municipal Utility District (EBMUD) explains that the zinc corrodes first. Once it is gone, the steel underneath starts to corrode. EBMUD also says it was common before the 1960s. It is not generally used for drinking water today.

So the zinc is a shield with an end date. It protects the steel from the water flowing through. However, it was never meant to last forever. Why galvanized pipes fail in Orange County homes, then, is mostly a question of time.

How Long Do Galvanized Pipes Last in Orange County?

In our experience, galvanized pipes last somewhere between 30 and 50 years. They start rusting well before that, usually after 20 to 30 years. InspectApedia, an inspection reference, gives a range of 40 to 60 years. The exact life depends on the pipe and the water.

Homes built in Orange County before the 1960s are the most likely to still have original galvanized plumbing. By any of these ranges, those pipes are past their expected life. Our guide to how long galvanized pipes last goes deeper on the numbers.

What Happens Inside Galvanized Pipes as They Rust?

Once the zinc is gone, rust and mineral deposits build up on the inside wall. EBMUD says mounds called tubercles can form and block the flow. That narrows the pipe. As a result, pressure drops and the water turns brown.

Leaks usually come last. They often start at the threaded joints, because the pipe wall is thinner where the threads are cut. InspectApedia describes the same pattern. So the failure is slow and hidden at first. Then it can show up all at once.

When Should You Replace Galvanized Pipes in Orange County?

Don’t wait for a catastrophe. If your home has original galvanized plumbing, plan the replacement before a section fails. Replace sooner if you see any of these signs:

• Rust-colored or brown water
• Low water pressure in more than one fixture
• Visible rust on exposed pipe
• Leaks in different spots

In our view, rusty water is a reason to call, not something to live with. Our guide to the signs of failing galvanized pipes in Orange County lists them in more detail. Seeing outside rust? Read what rusty galvanized pipes mean.

Can You Repair Galvanized Pipes Instead of Replacing Them?

A leaking section can be patched. However, the rest of the pipe is the same age and sees the same water. It is wearing out at about the same pace. Patching one spot buys time, but the next section fails on its own schedule.

That is why we typically recommend a whole-home repipe once galvanized pipe shows real signs of failure. We replace it with PEX or copper. Neither corrodes the way galvanized steel does.
