No. Galvanized pipe is what they used to use, and now should either be replaced with modern type of water pipe such as PEX or copper. COMMENT: Complete agreement. Galvanized served it's purpose and did bring water into a lot of people's homes for a lot of years. That was then, this is now. Today, it would be a dead last choice for a plumbing system.
