“Wait a minute,” you’re thinking as you look down from the hyper title written above. “Copper doesn’t corrode! That’s why copper is used for modern plumbing instead of steel.”
Well, you’re almost right. Galvanized steel, once the Emperor of Home Plumbing Pipes, was toppled from the imperial indoor plumbing throne in the 1960s because of its tendency to corrode with time, not only leading to breaks and leaks, but also the contamination of drinking water. Copper replaced it: a material that’s not only lighter and less expensive, but also corrosion resistant.
