Which material is commonly used for sewer lines?

Sewer lines are often constructed from various materials, each of which has unique benefits. The correct answer highlights that all the mentioned materials—PVC, ABS, and cast iron—are commonly used for sewer lines.

PVC (Polyvinyl Chloride) is widely utilized due to its lightweight, corrosion resistance, and ease of installation. It is especially favored for residential plumbing and drainage systems because it does not rust or degrade over time.

ABS (Acrylonitrile Butadiene Styrene), similar to PVC, is also a plastic piping material that is highly durable and resistant to impact and chemical damage. It is particularly valued in cold weather environments due to its ability to withstand lower temperatures without cracking.

Cast iron has been traditionally used in plumbing for many years, especially in older buildings. It is known for its strength and sound-dampening properties, making it ideal for heavy-duty applications and in scenarios where noise from wastewater flow is a concern.

Including all these materials as common choices emphasizes the versatility and adaptability needed in plumbing systems to accommodate various environmental conditions and installation preferences. Each material has a specific use case that makes it suitable for sewer line applications, reinforcing the understanding that plumbing professionals must select the right material based on the project requirements, local codes,
