Late 40's house - replumbed to copper. Outside the service entrance, I've found a maze of buried new and old lines, with a number of copper and (out of service) galvanized lines laid across each other in direct contact. The galvanized lines show significant corrosion where they're in contact with the copper lines, and of particular concern is a still-in-service galvanized natural gas line in firm contact with a copper line.
I assume that (a) this is not a good thing, and (b) the copper and galvanized lines should be seperated/insulated from each other?
On the gas line, there's significant corrosion bloom "bleeding" from the galvanized line to the copper. At what point should I be concerned that the gas line needs replacing?
