In plumbing, what is a common use for polyvinyl chloride (PVC)?

Polyvinyl chloride (PVC) is widely used in plumbing, particularly for water supply lines. This material is favored because of its durability, resistance to corrosion, and ability to handle high levels of pressure, making it an excellent choice for transporting potable water.

PVC is also lightweight and easy to install, which simplifies the plumbing process significantly. Its smooth interior surfaces help to reduce the likelihood of clogs and improve flow efficiency when used in water supply systems. This characteristic is particularly important in maintaining clean drinking water standards.

While PVC can be utilized in sewage systems, certain applications in that area may require different types of piping materials designed specifically for the conditions of wastewater transport. Therefore, its primary and most recognized use in plumbing applications remains with water supply lines, highlighting why selecting this option is valid and practical.
