What type of pipe is commonly used for potable water supply in plumbing systems?

• A. Cast iron pipe
• B. PVC pipe
• C. Copper pipe
• D. ABS pipe

Answer: (C)

Copper pipe is widely recognized as a reliable choice for potable water supply in plumbing systems. This pipe material offers excellent durability and resistance to corrosion, which is essential for maintaining water quality. Copper's ability to withstand high temperatures and pressures makes it suitable for both hot and cold water lines. Additionally, copper has natural antimicrobial properties that can help prevent bacterial growth in the water supply, further ensuring its safety for drinking purposes. The other materials mentioned have specific uses where they excel, but they are either not as widely approved for potable water or have limitations in certain applications. For instance, while PVC pipe is often used for drainage and waste applications due to its lightweight and corrosion resistance, it is not typically allowed for hot water service or under sink installations in many building codes. Cast iron pipe is primarily used for drainage, waste, and vent systems because of its strength and sound-dampening qualities but is too heavy and prone to corrosion for potable water use. ABS pipe, like PVC, is also used mainly for drainage systems and is not generally approved for drinking water supply due to potential leaching issues. These characteristics make copper pipe the preferred material for delivering clean, safe drinking water in plumbing systems.
