Is galvanized steel bad for plumbing?
Galvanized pipes are steel pipes that have been coated with zinc in an attempt to prevent rust and corrosion. Unfortunately galvanized pipes corrode and rust on the inside after years of exposure to water, which is bad news for your plumbing considering how frequently water runs through it.
How long will galvanized steel last?
A key benefit of using Hot Dip Galvanizing is its durability. Data shows that galvanizing can provide between 34 to 170 years of protection for steel.
Is galvanized steel as strong as regular steel?
Much like its counterpart, galvanized steel is also created with the purpose of protecting against rust and corrosion. While galvanized steel is cheaper, stainless steel is stronger. Again, this is due to the fact that it contains chromium, which is stronger and more durable than zinc-covered steel.
What’s the life expectancy of galvanized steel pipes?
Your insurance company’s concerns with galvanized steel plumbing Galvanized steel pipes, commonly installed in homes prior to 1950, have an average life expectancy of 40–50 years. Over time, the galvanized steel pipes begin to rust or corrode from the inside out, resulting in reduced water pressure and restricted water flow.
Can a galvanized water line be used in a house?
The process of dipping steel pipes into molten zinc to galvanize them has been around since the early 19th century, and galvanized pipes still are common in outdoor and industrial water systems. Plumbers don’t use them for residential plumbing, however, because they have better alternatives in copper and CPVC pipes.
What causes a galvanized water line to corrode?
Galvanized steel pipes tend to corrode from the inside, and the corrosion gradually reduces the internal cross-section and restricts waterflow. A third reason is that galvanized pipes and fittings eventually rust and begin to leak.
What happens when galvanized steel pipes start to rust?
Over time, the galvanized steel pipes begin to rust or corrode from the inside out, resulting in reduced water pressure and restricted water flow. This presents an increased risk of leaks or ruptures occurring in the pipes and the potential for flood damage.

Can a galvanized steel water line cause corrosion?
Yes, you can see signs of corrosion from galvanized steel pipes before you notice a water line break. Signs include rusty colored water, rust around pipe joints, pitted rust spots on pipes, or low water pressure.
