Which pipe material is typically used for drainage systems?

• A. PVC
• B. CPVC
• C. PEX

Answer: (A)

PVC, or polyvinyl chloride, is the correct choice for drainage systems primarily due to its properties that make it well-suited for handling wastewater and stormwater. PVC is lightweight, resistant to corrosion, and has a smooth interior surface that facilitates efficient flow and minimizes blockage. Additionally, it is cost-effective and relatively easy to install, making it a popular choice for both residential and commercial drainage applications. Other materials listed, such as CPVC and PEX, are designed for different applications. CPVC (chlorinated polyvinyl chloride) is typically used for hot and cold water distribution systems due to its ability to withstand higher temperatures. PEX (cross-linked polyethylene) is commonly used for potable water piping and heating applications because of its flexibility and resistance to freezing, but it is not usually selected for drainage purposes. This distinction is crucial to understand when considering the appropriate material for specific plumbing systems.
