Polyvinyl chloride (PVC) is commonly used for piping systems due to its lightweight, durable, and corrosion-resistant properties. It is particularly favored in plumbing, irrigation, and various industrial applications. PVC pipes are easy to install and can withstand a wide range of chemicals, which makes them versatile for both residential and commercial uses.

The high resistance to environmental factors and a smooth internal surface that allows for effective fluid flow further enhance PVC's suitability as a piping material. In addition to its practical advantages, PVC is also cost-effective, which makes it a popular choice among contractors and builders.

In contrast, wood is not suitable for standard piping systems due to its susceptibility to decay and water damage. Rubber bands lack the structural integrity needed for carrying fluids at various pressures, while glass, while it can be used in specific applications, is prone to breakage and is not as practical for general piping use as PVC.
