Which piping material is known for being lightweight and corrosion resistant?

The selection of PVC (polyvinyl chloride) as the correct piping material is based on its notable attributes of being both lightweight and highly resistant to corrosion. PVC is a type of plastic that is commonly used in plumbing applications due to these characteristics.

Its lightweight nature makes installation easier and reduces overall transportation costs, especially when compared to more traditional materials like cast iron or galvanized steel. Additionally, PVC does not rust or corrode over time, which means it maintains its structural integrity and does not contribute to issues like water quality degradation associated with corrosion. This corrosion resistance is particularly beneficial in various environments, whether the piping is installed above ground, underground, or in systems that handle chemical substances.

In contrast, cast iron is much heavier and although it has good durability, it can rust and corrode over time when exposed to moisture. ABS (acrylonitrile butadiene styrene), while also lightweight and resistant to chemicals, is not as widely used in certain plumbing code areas, particularly for pressure applications. Galvanized steel provides some corrosion resistance due to its zinc coating but can eventually corrode and is considerably heavier and more difficult to work with than PVC. Thus, the unique combination of being lightweight and corrosion-resistant makes PVC an optimal choice in
