How big of a concern is galvanized water supply line?
Hello, home inspection came back for a 1977 home that state:
"Observed a galvanized water supply line in attic over master bedroom was heavily
corroded appears to be leaking. This is common with older galvanized pipe systems and
there may be more of this in areas that were not accessible. We recommend further
inspection by a licensed plumber and repair as necessary."
How concerned should I be? Thanks!
