About Galvanized and Polybutylene Pipe Replacement

Older pipe fails from the inside. Replace it before it floods you.

Galvanized steel pipe rusts from the inside, narrowing until pressure drops and water turns brown. Polybutylene, a gray plastic used in some homes decades ago, is known for failing at fittings.

We identify what you have, explain your options and replace aging pipe with copper or PEX.
