What happens if a galvanized pipe rusts?
Galvanized pipes can rust completely from the inside out. Water that passes through a rusty pipe that hasn’t been turned on for a while typically appears brown or rust colored. According to Joe Bany, a John Moore Plumbing Manager, pinhole leaks plague rusted pipes. After pipes rust from the inside out, they will leak and then seal themselves with more rust, Bany says. Then they rust more—to a point where they do not seal back with rust. This, of course, causes water damage. If you take a look at pipes like these you’ll see rust or brown spots on the pipe, which are old pinholes that have leaked and sealed, as well as white or calcium spots on new locations.
