What material is commonly used for drainage systems due to its corrosion resistance?

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

Answer: (B)

PVC, or Polyvinyl Chloride, is a widely used material for drainage systems primarily due to its high resistance to corrosion. This property is particularly advantageous in plumbing applications where pipes are exposed to moisture, chemicals, and various environmental factors that could lead to degradation over time. One of the key benefits of PVC is its lightweight nature, which simplifies installation and handling compared to heavier materials like cast iron or galvanized steel. Additionally, PVC does not rust or corrode, unlike metal options, meaning it has a longer lifespan and often requires less maintenance. This makes it a practical choice for both residential and commercial drainage systems. While materials like copper and cast iron are used in some plumbing applications, they do not offer the same level of corrosion resistance as PVC, and galvanized steel is prone to rust over time when exposed to moisture. Therefore, when considering material options for drainage systems, the corrosion resistance, durability, and ease of handling of PVC make it the preferred choice.
