Corroding Vent Pipe
Posted by JimB on December 04, 2001 at 22:03:54:

Any idea why a vertical copper bathroom vent pipe would corrode? I'm having a bathroom remodeled and after opening up the walls, we found the vent pipe to the roof was severely corroded (almost looks like something was spilled on it) - complete with pencil and finger-size holes! I guess that explain the occasional smell.
