What type of pipe is typically used for drain, waste, and vent (DWV) systems?

The use of PVC (Polyvinyl Chloride) or ABS (Acrylonitrile Butadiene Styrene) pipes in drain, waste, and vent (DWV) systems is primarily due to their properties that make them suitable for this type of plumbing application. Both materials are lightweight, resistant to corrosion, and offer excellent chemical resistance, which is essential for managing the various waste materials and liquids found in plumbing systems.

PVC is often used because it can handle a range of temperatures and pressures found in residential and commercial applications, while ABS is known for its resilience and is particularly advantageous in colder climates due to its impact resistance. Both materials are also relatively easy to install, as they can be cut and joined using solvent cement, leading to a secure, leak-proof system.

Steel, galvanized, and copper pipes, while they have their own applications in plumbing (such as for water supply lines), are not commonly used for DWV systems. Steel and galvanized pipes can corrode over time when exposed to moisture and waste, which can lead to blockages and leaks. Copper, while durable and long-lasting, is typically more expensive and less compatible with the kinds of fluids found in drain and waste systems, making PVC and ABS the preferred materials for these
