How To Tell If You Have Galvanized Pipes
Plumbers Serving San Angelo, TX, Since 2004
If your home was built before the 1960s, there’s a good chance it may still have galvanized steel pipes in its plumbing system. While these pipes were once a popular solution for water lines due to their durability, they’ve since proven to be more of a liability than a benefit.
At Lone Star Contracting, we’ve helped countless San Angelo homeowners identify and replace outdated galvanized piping — and we’re here to help you do the same.
What Are Galvanized Pipes?
Galvanized pipes are steel pipes that have been coated with a layer of zinc to help prevent corrosion and rust. They were widely used in American homes for water supply lines from the early 1900s through the 1950s.
While the zinc coating initially helps delay corrosion, over time that protection wears off. Once that happens, the steel underneath begins to corrode — and that’s when problems start.
Why Are Galvanized Pipes A Problem In Older Homes?
1. Internal Rust And Corrosion
Despite the zinc coating, galvanized pipes will rust from the inside out. You may not see visible damage at first, but the inner walls can corrode significantly, reducing water flow and affecting water quality.
2. Reduced Water Pressure
One of the most common symptoms of corroded galvanized piping is low water pressure. As rust builds up inside the pipe, it narrows the passage for water, causing noticeable slowdowns at faucets and showers.
3. Contaminated Water
Galvanized pipes can release iron and other heavy metals into your drinking water. In some cases, the corrosion can even trap lead particles — especially if your home’s water system has had lead components in the past.
4. Pipe Leaks And Bursts
Once corrosion sets in, the structural integrity of galvanized pipes weakens. Over time, this makes your home more vulnerable to leaks and even pipe bursts, especially in areas with hard water like San Angelo.
Signs You Might Have Galvanized Pipes
If you’re unsure whether your home has galvanized pipes, here are some telltale signs to look for:
- Your home was built before 1960 and hasn’t had a major plumbing update
- Rust-colored water coming from your faucets, especially after being unused
- Staining around fixtures or in tubs and sinks
- Inconsistent water pressure, particularly in the upper floors
- Visible gray or silver pipes in your crawlspace or basement with threaded fittings
To confirm, you can test with a magnet. Galvanized steel pipes are magnetic — unlike copper or plastic piping.
Will Galvanized Pipes Rust?
Yes, and that’s the root of the problem.
While the zinc coating delays rusting, it’s not permanent. Once the protective barrier breaks down, the underlying steel begins to oxidize — leading to pipe deterioration, water discoloration and eventual failure.
In San Angelo’s dry and mineral-rich climate, galvanized piping tends to degrade even faster. If your pipes are older than 50 years, rust is almost guaranteed.
Are Galvanized Pipes Bad?
While not immediately hazardous, galvanized pipes pose a risk to your home’s plumbing and your family’s comfort. They:
- Compromise water quality
- Reduce water pressure
- Increase the likelihood of leaks
- Often lead to expensive water damage repairs
In short, they’re outdated — and for the health and efficiency of your plumbing system, they should be replaced.
