Why Replace Galvanized Water Lines?

What Are Galvanized Water Lines?

​

Galvanized pipes are steel pipes coated with a layer of zinc to prevent rust. While this worked for a time, the zinc coating eventually wears away, allowing the steel underneath to corrode.

Problems With Galvanized Pipes

​

• Corrosion and Rust: As the pipes corrode, rust builds up inside, narrowing the pipe and reducing water flow. This can lead to brown or discolored water, low water pressure, and frequent fixtures clogs.

• Leaks and Water Damage: Corroded pipes are prone to pinhole leaks and bursts, which can cause hidden water damage behind walls, under floors, or in crawlspaces.

• Lead Contamination: One of the biggest concerns with old galvanized pipes is the potential for lead in your water. While galvanized steel itself doesn’t contain lead, many older homes have sections of lead pipe or used lead-based solder to join pipes. Over time, particles of lead can become trapped inside the rough interior of galvanized pipes, then slowly release into your water supply—especially if the pipes are disturbed or corroding.

• Health Risks: Lead exposure is especially dangerous for children and pregnant women, and there is no safe level of lead in drinking water. Even low levels can cause developmental and neurological issues.

• Inspection and Insurance Issues: Many home inspectors flag galvanized pipes as a risk, and some insurance companies may deny coverage or require replacement before issuing a policy.

Signs You Have Galvanized Pipes

​​

• Home built before the 1970s.

• Low water pressure at multiple fixtures.

• Discolored or rusty water, especially after the water has been off for a while.

• Visible gray, metallic pipes in the basement, crawlspace, or utility areas.

 

What Should Homeowners and Buyers Do?

​

If your home has galvanized water lines, consider proactive replacement with modern materials like copper or PEX. This upgrade not only improves water quality and flow but also protects your family’s health and can increase your home’s value.

 

Bottom Line:
Replacing galvanized pipes eliminates the risk of corrosion, leaks, and potential lead exposure—making your plumbing safer, more reliable, and more attractive to buyers.
