What You Should Know About Galvanized Pipes

Galvanized pipes are steel pipes that have been dipped in a protective zinc coating to prevent corrosion and rust. Galvanized piping was commonly installed in homes built before 1960. When it was invented, the galvanized pipe was an alternative to lead pipe for water supply lines.

Galvanized water piping was the state of the plumbing art in 1941. Galvanizing is a metallurgical process used over the past 150 years to coat steel or iron with zinc to inhibit corrosion. The life span of the galvanized pipe used for water delivery is about 40 years.

Although galvanized (zinc-coated) pipe is still considered to be a safe transport material for drinking water, there are some potential health concerns if the water supply is corrosive due to its acidic condition (low pH).

Is galvanized pipe safe to touch?

The galvanized coating will not be absorbed, by your skin. However, it could have a thin coating of rust preventive oil. Some people have allergic reactions to the oil. You should be wearing gloves.

Is galvanized steel rustproof?

Galvanization is a zinc coating applied over the top of steel. It prevents rust and corrosion for longer than paint will, often for 50 years or more, but eventually that brown rot will set in.
