Is CPVC plastic used in high-temperature installations?

• A. True
• B. False
• C. CPVC is not used in high-temperature installations
• D. CPVC cannot handle high temperature

Answer: (A)

CPVC is designed to withstand higher temperatures than standard PVC, so it is used for hot-water installations. Its heat tolerance means it can carry hot potable water safely, typically up to about 180°F (82°C), and in some systems up to about 200°F (93°C) under specific pressure ratings. This higher temperature resilience lets CPVC replace PVC in hot-water piping while remaining a plastic option rather than metal. Just be sure the specific CPVC product and joint method are rated for the system’s temperature and pressure, since very high-temperature or high-pressure applications may require metal piping or specialized plastics.
