What is the advantage of using CPVC over PVC in plumbing?

Using CPVC (Chlorinated Polyvinyl Chloride) in plumbing offers the significant advantage of its ability to handle hotter water temperatures compared to standard PVC (Polyvinyl Chloride). CPVC is specifically designed to withstand operating temperatures up to around 200°F (93°C), making it suitable for hot water lines, including those in hot water heating systems. This heat resistance is crucial in residential and commercial plumbing applications that require safe transportation of hot water without the risk of pipe deformation or failure.

Unlike CPVC, PVC is limited to carrying cold water and cannot be used for hot water applications due to its lower heat tolerance, typically around 140°F (60°C). This distinction highlights why CPVC is often the preferred choice in situations that involve hot water distribution, contributing to its acceptance in both residential plumbing and industrial sectors.
