Several types of material has been used in the past for pipes - brass, copper, CPVC, galvanized, lead, polybutylene, cast iron, and even wood for example. Consumers today have many choices when it comes to selecting products to use for home plumbing. Although products such as lead service lines are no longer used due to health concerns, copper, CPVC, PVC, and PEX are just a few of the options available today for residential plumbing uses.
