Why Are Galvanized Pipes a Problem in Older Homes?

Though every house is different, Stellar Plumbing knows that galvanized steel and iron aren’t the best options for plumbing systems, especially in older residences. See what we have to say on the matter as a trusted, reliable plumber in Streamwood, IL, in the guide below.

What Are Galvanized Pipes?

Most plumbing systems in the early stages of modern history used lead-based pipes. Unfortunately, lead is a dangerous material due to its health risks, and degraded pipes contributed to lead poisoning in many homes in and around Streamwood before plumbers stopped installing these types of pipes. 

Galvanization solved the lead pipe problem. It protects iron and steel pipes from premature rust and deterioration with a protective zinc coating on the pipes’ interior. Around 1960, galvanized iron and steel pipes became a staple for residential plumbing systems. 

Since Streamwood has many homes built before and after the change of pipeline materials, it’s not uncommon for dwellings to have galvanized materials within their plumbing systems. The problem is with galvanized pipe corrosion.

Though galvanization helped prevent pipe rust and deterioration, the coating itself wears down over time due to water constantly flowing through the pipes. As such, this type of plumbing can still result in high concentrations of lead in a property’s water supply. 

Why Is Lead Dangerous?

Lead is a toxin that can seep into drinking water when certain plumbing materials containing lead corrode such as pipes and faucets. Exposure to lead in drinking water can lead to complications like increased blood pressure, reduced kidney function in adults, and slowed growth and anemia in children.

Despite the protection galvanization offers against lead poisoning, the coating and pipes will degrade, and 30- or 40-year-old plumbing systems are at risk of leeching lead into a property’s drinking water supply.

Why Are Galvanized Pipes Problematic for Older Houses in Streamwood?

Why are galvanized pipes a problem in older homes? After inspecting and handling galvanized pipes over the years in Streamwood, it’s evident to many plumbers and professionals that newly installed pipes work well, yet old pipelines are problematic. After decades of use, galvanized water pipes can develop multiple problems, including the following:

• Rust and Corrosion. Though the zinc coating creates a barrier between a pipe’s interior and water, the coating won’t last forever. The original material will also degrade as the coating deteriorates, leading to rust and corrosion.
• Reduced Water Pressure. As galvanized pipes deteriorate, their joints become vulnerable to leaks, which can reduce water flow. Decades worth of mineral deposits can also cause water flow restrictions.
• Poor Water Quality. One of the noticeable consequences of having old galvanized iron or steel plumbing in your Streamwood home is discolored water. Significant corrosion can turn your water a rusty, reddish-brown color.

How Can You Tell If Your Older Streamwood House Has Galvanized Pipes Within Its Plumbing System?

Even if the plumbing in your Streamwood house seems reliable, your household could be in trouble if you’re still relying on old, corroded galvanized pipes. If you’re unsure if your plumbing has galvanized pipes, inspect your pipes.

Galvanized pipes can change from a bright nickel color to a darker, duller hue. They’re also magnetized. If you scratch your pipes and see a color resembling a penny, your pipes are copper, but white pipes indicate plastic.

What’s the Best Way To Deal With Galvanized Pipes?

You might worry about common pipe replacement issues like cost and interruption to daily activities. Still, installing lead-free pipes is the best way to reduce your Streamwood home’s lead contamination risk.

Reliable, lead-free materials like PEX and copper piping can save you money on expensive repairs due to pipe deterioration. This option is best for Streamwood homes with decades-old galvanized pipes. Routine maintenance can keep newer pipelines in good condition.
