when did they stop using lead solder in plumbing
Plumbing The use of lead for potable water declined sharply after World War II because of increased awareness of the dangers of lead poisoning. At this time, copper piping was introduced as a better and safer alternative to lead pipes.[11][12]
Plumbing Present-day water-supply systems use a network of high-pressure pumps, and pipes in buildings are now made of copper,[25] brass, plastic (particularly cross-linked polyethylene called PEX, which is estimated to be used in 60% of single-family homes[26]), or other nontoxic material. Due to its toxicity, most cities moved away from lead water-supply piping by the 1920s in the United States,[27] although lead pipes were approved by national plumbing codes into the 1980s,[28] and lead was used in plumbing solder for drinking water until it was banned in 1986.[27] Drain and vent lines are made of plastic, steel, cast-iron, or lead.[29][30]
