How FlowGuard® CPVC Prevents Microbial Water Contamination

Clean, potable water is arguably the most critical element for human well-being, and the adverse effects of contaminated water can be seen across the globe.

FlowGuard^® CPVC pipes and fittings are less susceptible to bacterial buildup and resistant to the chlorine that water treatment facilities use to kill bacteria and disinfect water supplies, making it a more viable solution than other piping materials for preventing microbial water contamination.  

How Microbial Water Contamination Happens

Biofilm forms when bacteria adheres to surfaces in an aqueous environment and begins to excrete a slimy, glue-like substance. Water treatment plants utilize chlorine and chlorine dioxide to kill this bacteria and keep water safe.

It is the chlorine that causes corrosion in certain piping materials, weakening the material and creating small gouges along the pipe’s surface.

CPVC Prevents Water Contamination

Kiwa Water Research conducted a study in which they tested 14 different materials that commonly come in contact with potable water for microbial biofilm formation. CPVC consistently tested better at preventing water contamination than other available piping materials, including green pipe (PPR).

Thanks to its higher density, CPVC effectively reduces bacterial attachment by reducing the contact area between bacteria cells and the pipe’s surface. This also helps to protect the integrity of the CPVC material from chlorine attack as well as heat and pressure. The result is a continuously smooth surface that does not allow bacteria to gain a foothold, and stands up to water purification measures.  

FlowGuard CPVC Provides Superior Water Quality

FlowGuard CPVC has been approved for potable water applications by major international agencies including NSF International, KiWA, and WRAS―ensuring it does not contribute any harmful or dangerous products to the drinking water it transports.
