What type of piping is typically used for sewer lines?

The use of ABS (Acrylonitrile Butadiene Styrene), PVC (Polyvinyl Chloride), or cast iron for sewer lines is based on their durability, resistance to corrosion, and ability to handle the various pressures and flows associated with wastewater. These materials are specifically engineered to withstand the harsh conditions found in sewer applications, making them ideal choices.

ABS and PVC are both lightweight, easy to work with, and provide excellent chemical resistance. They are particularly popular for residential plumbing due to their affordability and ease of installation. Cast iron, on the other hand, has a long history of use in sewer applications because of its strength and durability, especially in systems that require high pressure or involve heavy loads.

By utilizing these materials, plumbing systems can effectively manage the challenges presented by sewage, ensuring reliable and long-lasting performance. Other materials like steel, copper, or brass, while valuable for various plumbing applications, are not typically used for sewer lines due to their susceptibility to corrosion or inability to handle the specific requirements of wastewater transport.
