Care & Maintenance Document

The following "Care & Maintenace Document" has been developed as an educational tool to advise building owners that their structure contains a CPVC fire sprinkler system. It contains general information in caring for and working around the CPVC sprinkler system to ensure it will function properly when needed.


CONGRATULATIONS, your building structure contains a state of the art life safety system. Your CPVC fire sprinkler system will enhance the safety and security of your building when properly cared for. CPVC Fire Sprinkler Products resist attack from a wide range of chemicals that are corrosive to metallic piping. As with any piping material, there are however, certain chemicals that can be detrimental to CPVC. Occasionally some of these chemicals may be found in some construction products, site preparations and building maintenance. There are certain things that you need to be mindful of in caring for or working around your CPVC fire sprinkler system.
