Which material is commonly used to replace cast iron pipe?

The use of PVC (Polyvinyl Chloride) to replace cast iron pipe is common due to its numerous advantages. PVC is lightweight, which simplifies the installation process compared to the heavier cast iron. This ease of handling makes it particularly attractive for large projects or tight spaces where maneuverability is limited.

Additionally, PVC is resistant to corrosion and various chemicals, which helps to ensure a longer life span and requires less maintenance than cast iron. Since PVC does not rust or corrode, it mitigates issues related to water quality that can occur with aging cast iron pipes.

Another important factor is that PVC is typically more cost-effective than cast iron, both in terms of material cost and installation labor, making it a popular choice for plumbing and drainage systems. Its versatility, cost efficiency, and physical properties contribute to its widespread usage as a replacement material for cast iron in various applications.
