Radon lurking in your water supply is a silent threat that can insidiously degrade your home's air quality and imperil your family’s health. Unlike ordinary water contaminants, radon gas seeps out during everyday water use—showering, cooking, or washing dishes—releasing radioactive particles into your indoor air. This invisible infiltrator can amplify respiratory issues, increase cancer risk, and cause your household to suffer in ways you rarely suspect until damage has already taken root.

The system that fixes it

The Fleck Radon in Water System offers a precise and powerful defense against radon contamination directly at the water source. Central to its design is the Fleck 5600 SXT backwashing control valve—an industry-leading component engineered to automate thorough cleaning cycles that maintain peak performance without manual intervention. This valve meticulously controls the flow and timing of water treatment, ensuring the media remains fresh and effective. Built atop a deep backwashing carbon tank, the system leverages a robust column of large-bed granular activated carbon (GAC) media, which captures radon before it can off-gas into your living spaces. The seamless integration of genuine Fleck hardware means repairs and maintenance are straightforward, reliable, and backed by a brand known for durability.

How the media works

The heart of this system is its large-bed granular activated carbon (GAC) media—a specialized substance designed to trap radon molecules deep within its porous structure. As water flows through the thick carbon bed inside the tank, radon gas adheres to the media, effectively captured before it can evaporate into your home's air. Unlike standard carbon filters, this large-bed setup provides extensive surface area and prolonged water-media contact time, ensuring radon is intercepted thoroughly. Periodic backwashing flushes the media bed, clearing accumulated particles and restoring its absorption capacity. This clever media function is the cornerstone of the system’s superior radon removal performance.

A The Fleck Radon in Water System is designed to capture and remove the vast majority of radon gas in your water before it off-gasses into your home’s air, significantly reducing exposure and health risks.

Q? How often does the system require maintenance?
A Thanks to the automated Fleck 5600 SXT backwashing control valve, cleaning cycles are scheduled routinely without manual effort. Periodic media replacement will depend on your water usage but is simplified by the serviceable, genuine Fleck hardware.
