When it comes to choosing materials" for a fire protection system, BlazeMaster® CPVC offers many advantages over steel pipe. It’s easier to install, will never corrode and provides a cost-effective solution for a wide range of commercial as well as residential projects.

Yet some installers and specifiers still have reservations about using CPVC because of lingering myths about durability, cost, strength, flame resistance and others. These outdated misconceptions remain too common despite a remarkable track record. BlazeMaster CPVC has been protecting people and property for over 30 years with more than 2 billion feet installed globally.

Get the Facts

Here’s a quick overview of six common misconceptions – and the facts to address them. For a more in-depth look at the facts about BlazeMaster CPVC’s advantages, check out our new report, “Addressing 6 Common Misconceptions About CPVC Fire Protection Systems.”

Misconception 1: CPVC could melt in a fire.

Truth: When installed per its listings, BlazeMaster resists heat and fire and maintains its structure when directly exposed to a flame. BlazeMaster also offers superior hydraulics compared to steel to ensure the system delivers water to suppress a fire and stop it from spreading.

Misconception 2: All brands of CPVC are basically the same.

Truth: In independent head-to-head testing against Spears FlameGuard®, BlazeMaster CPVC showed a significant advantage in pressure burst testing and impact resistance. And only BlazeMaster offers the FBC System Compatible Program that helps ensure chemical compatibility of the pipe and ancillary products.

Misconception 3: CPVC is too expensive.

Truth: Compared to traditional steel systems, BlazeMaster CPVC can reduce costs for both the installer and the building owner. Heavy steel pipe requires pre-fabrication and teams of two or more people to install, while BlazeMaster is fabricated entirely in the field and installation is a one-person job. Unlike steel pipe, BlazeMaster reduces repair and maintenance expenses because it never corrodes; in fact, it is designed for a 50 year service life.

Misconception 4: CPVC is bad for the environment.

Truth: BlazeMaster CPVC has half the climate change impact compared to steel, based on an ISO-compliant, peer-reviewed life-cycle assessment. The study showed BlazeMaster CPVC outperforms steel on 12 out of 13 environmental categories, such as climate change impact and metal depletion.

Misconception 5: CPVC is only for residential projects.

Truth: BlazeMaster CPVC is UL Listed for all light-hazard occupancies as defined by NFPA 13, 13R and 13D. While best known for its use in apartments and townhomes, it is widely used in schools, offices, hospitals, high-rises and other commercial facilities. In fact, contractors and building owners commonly choose BlazeMaster CPVC for commercial retrofits, as its flexibility and light weightedness provide an easier, faster install in existing structures.

Misconception 6: CPVC installation is difficult.

Truth: Light, flexible BlazeMaster CPVC is installed with a quick, simple joining process that allows one person to cover an area. By comparison, installation of steel pipe requires two or more people along with use of torches, heat fusion techniques and pre-fabrication. CPVC reduces installation time – and labor costs.

One more truth: Because of its advantages over steel, BlazeMaster is the most specified non-metallic piping system in the world. By clarifying the facts about CPVC, we hope to spur wider usage to save more lives and protect more property.
