For which applications can PVC pipe be used in residential buildings?

PVC pipe is commonly utilized in residential buildings for various plumbing applications due to its durability, lightweight nature, and resistance to corrosion. In the context of underground drainage systems, it is particularly advantageous.

When discussing underground drain, waste, and vent applications, PVC pipe is ideal because it can withstand the pressures and conditions found below ground. Its chemical resistance allows it to handle the waste and runoff without degrading over time. Moreover, PVC piping's smooth surfaces facilitate the free flow of wastewater, reducing the risk of clogs.

In contrast, while PVC can be utilized for other applications like above ground water distribution, building drains, and vent systems, it is essential to follow local codes and regulations. Typically, above-ground applications might require different materials that can better handle thermal expansion or structural loads. Therefore, using PVC in underground systems is specifically recognized as suitable and compliant with plumbing codes, making it the best choice in this context.
