Were the pipes lead? Or were the solder joints lead?
In the old days, we used galvanized that wasn't threaded together, but soldered. Lead was commonly used; you would see a vat of molten lead at the jobsite. The pipes were fitted together and the lead pressed into the joints to connect it and seal it. But the pipes themselves were not made of lead.
Over here, that practice ended decades ago and we went to copper tubing with lead free solder. Nowadays, it's often polyvinylchloride or the latest craze- that PEX crap.
