Galvanized Pipes

You probably don’t spend much time thinking about your home’s plumbing — unless there are problems. If you’re experiencing plumbing issues, these could be linked to your home’s pipes. The most common cause being galvanized pipes. What are they and what can you do if your home has them?

What are galvanized pipes?

Galvanized pipes are zinc-coated steel pipes intended to prevent rust and corrosion. These pipes were invented as an alternative to lead pipes and are commonly used in homes constructed prior to the 1960s. Unfortunately, despite the intended innovation of the protective zinc coating — galvanized pipes do inevitably rust and corrode. Over time, the protective zinc coating deteriorates — which leads to corrosion, rust, and a variety of plumbing problems.

How long do galvanized pipes last?

The average lifespan for galvanized pipes is about 40 to 50 years. While their lifespan might make them seem like a durable option — galvanized pipes gradually deteriorate and cause many problems while in place — including low water pressure, water discoloration, and leaks.

How to Tell if Your Home Has Galvanized Pipes

If you’re wondering whether or not your home has galvanized pipes, your first thought might be to look for rusty pipes. While galvanized pipes always rust over time, it’s not obvious from just looking at their exterior. This is because the pipes corrode from the inside out. Instead, look for these other telltale signs your home has galvanized pipes.

Water Discoloration

Does your water taste metallic? Have you noticed rust-colored stains in your bathtub or sinks? Do you see a reddish tint in your water? These are signs of iron in your water, which is caused by rusted galvanized pipes.

Low Water Pressure

Have you been noticing low water pressure in your home? Galvanized pipes could be to blame. The corrosion and deposits that occur in the pipes over time eventually create blockages, which lower your home’s water pressure.

Test your home’s water pressure by using a pressure gauge that measures in psi (pound per square inch). The average home water pressure ranges from 40 to 50 psi — so if your test yields a psi out of that range, corroded galvanized pipes are likely the culprit.


When your home has galvanized plumbing, the risk of water damage is high. Galvanized plumbing usually causes leaks behind walls and under floors, which can result in severe, costly damage. These hidden water leaks damage your home’s structural foundation, increase the risk of mold growth, and attract termites. So, if you’ve noticed musty odors, mold, peeling paint, insects, or warped foundational elements in your home, you should have a professional plumber inspect your home as soon as possible.
