CPVC (Chlorinated polyvinyl chloride) is widely used in homes and businesses for Hot and Cold drinkable water supply. CPVC is designed to withstand continuous operating pressures of 100 PSI at water temperatures of 180 degrees Fahrenheit. It is impervious to corrosion and mineral buildup within the pipe.
Also in the CPVC family are Genova Product's "Gripper Couplings". Gripper couplings are use to mechanically join Copper to CPVC, Copper to Copper, or CPVC to CPVC. They are excellent for making repairs in broken or leaking pipes!
