Early FlowGuard systems dating back to 1959 are still in service today, a testament to the material’s durability.
Flame Resistance
Building safety matters, when it comes to professional plumbing as well as keeping homes safe.
FlowGuard is ignition-resistant and self-extinguishing, with a high flash ignition temperature of 482°C; significantly higher than common alternatives like PPR (~340°C). In practice, that means the material won’t sustain burning once the flame source is removed, and contributes minimal smoke; key considerations for building safety compliance.
Resistance to Corrosion
FlowGuard is inherently resistant to the chlorine and chlorine dioxide used to keep potable water safe, avoiding the pitting, scaling and pin-hole leaks associated with metals and some plastics. This chemical resilience is why FlowGuard is widely specified for chlorinated water service and carries potable-water approvals in key markets.
Reduced Biofilm Potential
The high chlorine content and smooth interior surface of FlowGuard make it less hospitable to biofilms; the microbial communities that can harbour pathogens such as Legionella. Studies show CPVC’s comparatively lower biofilm formation potential versus materials like copper and PPR, helping systems maintain cleaner water throughout their service life. While good design and maintenance are essential, starting with a material that doesn’t encourage biofilm attachment gives plumbers a head start.
Installation Processes
Lasting systems begin at installation. FlowGuard uses solvent-cement welding, which fuses pipe and fitting at the molecular level; no open flames or heavy equipment required. When done correctly, the joint becomes one of the strongest parts of the system, with fast set and cure times that help keep projects on schedule. Clear, step-by-step guidance provided by our technical support teams around the world support repeatable quality on site, from surface prep and priming to proper assembly and curing.
Reliability and Service Life
To us, reliability means systems that do not fail. FlowGuard’s resistance to corrosion, combined with robust fire and hygiene performance translates to fewer leaks, fewer maintenance requirements and a longer serviceable life. With installations still performing after decades in the field, FlowGuard has the kind of track record that turns specifications into lasting success stories.
