No. The chemical composition of CPVC piping used in fire sprinkler systems is different than standard CPVC. About 50 years ago, scientists first developed an advanced CPVC polymer for use in fire sprinkler systems. The compound they developed was stronger at elevated temperatures and had a lower combustibility rating than standard CPVC.
CPVC fire sprinkler piping and fittings must meet certain standards in order to be approved for use in fires sprinkler systems. The standards for fire sprinkler system components are prescribed by regulatory and testing agencies including the National Fire Protection Association (NFPA), Factory Mutual (FM), Underwriters Laboratories (UL), the National Sanitation Foundation (NSF) and ASTM International (formerly the American Society for Testing and Materials). Standard CPVC piping and fittings for use in potable water plumbing systems and similar applications does not meet these standards and cannot be used in fire sprinkler systems.
