Methods of Water Treatment

Disinfectants are essential to the safety of drinking water, but strong disinfectants like chlorine dioxide can significantly reduce the lifespan of some plumbing materials.

The Rise of Chlorine Dioxide

Chlorine dioxide usage is up 104% in the U.S. since 2020. The powerful disinfectant is more effective than other chloramines, doesn’t add an unpleasant taste or smell to water and doesn’t create harmful byproducts. But not all piping materials can stand up to chlorine dioxide. Chlorinated polyvinyl chloride (CPVC) delivers superior resistance to chlorine-based disinfectants.

The Impact of Chlorine-Based Disinfectants on Piping

Chlorine dioxide has many advantages for water quality. But the disinfectant can have a significant impact on piping material longevity. Learn more about the science behind chlorine-based water disinfection and how a high-quality CPVC like FlowGuard Gold CPVC compares to polyolefins like PEX when carrying chlorine-treated water.
