How big of a concern is galvanized water supply line?

[Albert L.]

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!

@Albert L.

Yes replace the pipe as soon as you can do it. 

Not knowing your situation, if your property is located in an area that has freezing temps I would move it into a warm section of the house. If you are able to do the work yourself go with PEX, if it has to be performed by a licensed Plumber, he’s most likely going to run PEX.

While he’s at it take out as much and replace the remainder with the same, on our newly acquired or rehab properties we always convert over to PEX, it’s cheap, easy to work with and is trouble free (so far).

Did I mention PEX?

Good luck!
