CPVC has been used in plumbing since the 1950s and is a standard for hot-water applications.
Is CPVC safe for drinking water?
Yes. CPVC is commonly approved for potable water when installed correctly.
Can CPVC be used outdoors?
Yes, but it should be protected from direct sunlight to avoid UV damage.
How does CPVC compare to PEX?
CPVC is rigid and solvent-welded; PEX is flexible and uses mechanical fittings. Both can work for hot water lines.
