This was one of those situations where you can't see for more than 8 or 10 feet in any one direction at any one time because of ductwork, piers, etc. I crawled from spot to spot, stopping to look around when it seemed worth it. You know what, I'll bet that's actually an old galvanized steel water line. I found half a dozen places where the remaining galvanized lines were in bad shape, and some had been replaced fairly recently (in the last year or two). I already wrote in the report about the signs and recommended replacing all of it before it fails and causes damage. I think I' ve wasted your time gentlemen, my apologies. Thanks to Jon for the clue, I didn't have one. Duh! [:-dunce] Brian "Brain Cramp" G.
