when did copper piping start
For potable water use, galvanized iron piping was commonplace in the United States from the late 1800s until around 1960. After that period, copper piping took over, first soft copper with flared fittings, then with rigid copper tubing utilizing soldered fittings.oday, most plumbing supply pipe is made out of steel, copper, and plastic; most waste (also known as soil) out of steel, copper, plastic, and cast iron. The straight sections of plumbing systems are called pipes or tubes. A pipe is typically formed via casting or welding, whereas a tube is made through extrusion.
