CPVC pipe joints in a HYDRO heat system shall be joined by solvent cement.

• A. True
• B. False
• C. Not Determined
• D. Not Applicable

Answer: (A)

In hydro-heat piping, CPVC joints are made with solvent cement because CPVC is designed to be fused to fittings through solvent welding. The solvent cement softens the CPVC surfaces and, as the cement cures, the pipe and fitting fuse together to form a continuous, leak-tight bond that can handle the system’s hot-water conditions. This method provides a strong, uniform joint that’s rated for the temperatures and pressures of a hot-water heating system, unlike some other joining methods that may not maintain integrity under heat. Use the CPVC-specific primer and cement recommended by the manufacturer, apply primer to both pipe and fitting, apply the cement, insert fully, and hold until the bond sets. Following these guidelines ensures a reliable connection that remains secure under hydro-heat service.
