The Problem with Galvanized Pipes: Why It's Time to Upgrade


The world of plumbing changes more than you might realize. Over the last several decades, one of the biggest shifts has been the move away from galvanized pipes, which were widely used in the 1950s and 1960s. While they seemed like a good choice then, galvanized pipes have since come with a host of issues.

Today, we’ll explore the potential problems with galvanized pipes and why it might be time to consider an upgrade.

Key Takeaways

  • Galvanized pipes can lead to rusting, mineral buildup, and water contamination as they age.
  • The zinc coating meant to protect galvanized pipes wears away over time, leading to structural issues.
  • If you still have galvanized pipes, it’s important to consider upgrading to avoid leaks, water contamination, and other costly problems.

Let’s dive deeper into the specific issues that galvanized pipes can cause.

1. Rusting and Interior Decay

One of the most common problems with galvanized pipes is rusting. These pipes are coated with a layer of zinc to protect them from rusting, but over time, that coating wears away. Once the protective barrier is gone, the pipes become vulnerable to rust and decay.

As the pipes rust from the inside, the buildup can cause leaks or even lead to broken pipes. If your home still has galvanized pipes, this is a risk you’ll eventually face as the pipes age.

2. Mineral Buildup

Another issue with galvanized pipes is mineral buildup, especially in areas with hard water. The minerals in the water can react with the zinc coating, causing plaque to form inside the pipes. This plaque restricts water flow and can gradually degrade the pipe’s structural integrity.

If you notice reduced water pressure or discolored water, mineral buildup in your galvanized pipes could be the culprit.

3. Water Contamination

As galvanized pipes begin to degrade, trace amounts of rust and other corroded materials can start to seep into your water supply. At first, the contamination might be unnoticeable, but over time, it can worsen.

In severe cases, you might even see rusty, discolored water coming from your taps. No one wants to turn on the faucet and be greeted with orange, rusty water—it’s a clear sign that your pipes need attention.

What Should You Do About Galvanized Pipes?

If your home still has galvanized pipes, it’s important to be aware of the potential problems they can cause. From rust and mineral buildup to water contamination, the risks of keeping these aging pipes can lead to costly repairs and health concerns.

At Parker & Sons, we recommend having your pipes inspected by a professional plumber if you’re unsure about the condition of your plumbing system. If you do have galvanized pipes, it might be time to consider replacing them with more modern, durable materials like PEX or copper.

Final Thoughts: Time for a Plumbing Upgrade?

Galvanized pipes were once the standard, but their tendency to rust, clog, and contaminate water has made them outdated. If your home still relies on galvanized plumbing, it’s worth considering an upgrade to ensure your water supply remains clean and your plumbing system stays in top shape.
