The pipes in my Q all appear to be either flex-line, or copper.... I'm sure it's just a blanket measure to cover their own asses in case there are pipes that have not been replaced since '55.

That may make you have a false sense of security, when in fact the problem may still be there.  Question now is what type of solder did they use?  Did they use Lead Sodder to seal your connections?
