Invisible, odorless, and dangerously radioactive, radon seeping from your water can silently erode your home's air quality and jeopardize your family's health. Symptoms like unexplained respiratory issues or a persistent earthy smell in your tap water often go unnoticed, yet the true cost lies in potential lung damage and increased cancer risk over time. Without effective treatment, radon in water can literally undermine the safety and comfort of your living space.

The system that fixes it

Introducing the Pentek Radon in Water System — a robust, precision-engineered solution designed specifically to tackle radon contamination at its source. At its heart is the Pentek-series backwashing control valve, a genuine brand valve meticulously crafted for durability and effortless maintenance. This intelligent valve automates the backwashing process, flushing out accumulated contaminants to preserve peak performance without manual intervention. Supporting it is a deep carbon tank built for endurance, loaded with a large bed of granular activated carbon (GAC) media. This media traps radon effectively, preventing it from off-gassing into your home’s air and delivering cleaner, safer water round the clock.

How the media works

The core of this system’s effectiveness lies in its large-bed granular activated carbon (GAC) media. Think of it as a deep sponge made of tiny carbon granules with an enormous surface area. As water flows through this thick carbon bed, radon atoms cling to the granules, captured and held firmly before they can release radioactive gases into your home’s air. This method traps radon at the molecular level, preventing it from off-gassing and making your water—and your indoor air—safer. The deep bed design means longer contact time, so even low levels of radon are efficiently removed.
