Copper and plastic are popular materials used in the creation of water pipes and fittings. Copper has been the material of choice for the past few decades but plastic has come to challenge copper's dominance in the water piping market over the past 15 years. The rising cost of copper is contributing to plastic's popularity. They are both effective materials that can last several decades if maintained properly. These materials are associated with certain advantages and disadvantages.
