Yes, had a call once where the cond. for the upstairs furnace was tied into copper which ran down the wall to the basement sump pump. It deteriorated the copper and caused several leaks. They had to cut out a section of the wall and ceiling so it could be replaced with 3/4 pvc.
The 3/4 in copper was so thin in parts that I could smash it like alum. foil. this was where it developed several pin sized holes.

Behind the ostensible government sits enthroned an invisible government owing no allegiance and acknowledging no responsibility to the people.
