What material is commonly used for pipes in residential plumbing?

• A. CPVC (Chlorinated Polyvinyl Chloride)
• B. PVC (Polyvinyl Chloride)
• C. Galvanized steel
• D. Cast iron

Answer: (B)

Polyvinyl Chloride (PVC) is commonly used for pipes in residential plumbing due to its versatility and a number of advantageous properties. It is lightweight, resistant to corrosion, and easy to install, making it ideal for a variety of plumbing applications, including drainage, waste, and vent systems. PVC is also relatively inexpensive and can be manufactured in different sizes to accommodate various plumbing needs. Its smooth internal surface minimizes friction and allows for efficient flow of water, reducing the chances of clogs. Additionally, PVC does not rust or corrode, which contributes to its longevity and durability in a plumbing system. These beneficial characteristics make PVC a preferred choice for many residential plumbing projects, whether for new installations or repairs. Other materials like CPVC, galvanized steel, and cast iron have their own uses and advantages but are less common for general residential plumbing. CPVC is often used for hot water applications, while galvanized steel can be heavy and prone to corrosion over time. Cast iron, though durable, is typically reserved for specific applications like drainage systems due to its weight and cost.
