Calgary Plumbing: Copper on Its Way Out, Soon to be Succeeded by PEX
Copper began taking over plumbing in North America after World War II. By the 1970s, it had already cemented its place as the quintessential plumbing material. It was easier to work with and didn't corrode as easily as galvanized iron, its predecessor. Yet for all its good qualities, copper wasn't designed to last forever. As soon as treatment plants started adding chlorine to water, copper plumbing systems soon began to suffer the effects of corrosion. Even with the natural protective lining formed after reacting with oxygen, copper pipes eventually succumb to leaks. Given that Calgary uses chlorine to treat potable water, homes with copper plumbing are placed at a disadvantage.
