Invisible yet insidious, radon in your water silently infiltrates your home, releasing radioactive gases with every shower, tap, and laundry load. This unseen menace can trigger stale indoor air, mysterious odors, and worst of all, increased health risks for your family. Without a targeted solution, radon’s radioactive particles may accumulate, quietly threatening the safety and comfort of your living space.

The system that fixes it

The C-Series Radon in Water System is engineered specifically to combat radon contamination at its source: your water supply. At the core of this system sits the C-Series backwashing control valve—a genuine, serviceable brand valve that ensures precise, reliable operation and easy maintenance over the years. This valve orchestrates deep backwashing cycles that thoroughly cleanse the carbon tank, preventing clogging and maintaining peak performance. The tank itself is built on a robust foundation: a deep carbon tank designed to house a large bed of granular activated carbon media. This large-bed granular activated carbon (GAC) is uniquely positioned to capture radon before it can off-gas into your indoor air, effectively reducing the radon threat in both your water and home environment.

• Durable C-Series backwashing control valve ensures consistent system regeneration and easy servicing.
• Deep carbon tank designed for thorough media backwash, extending system life and media efficiency.
• Large-bed granular activated carbon media specifically selected to trap radon particles before off-gassing.
• Engineered to reduce indoor radon exposure originating from water sources, a critical but often overlooked problem.
• One-brand matched system for seamless compatibility and reliable performance over time.

Pick your size

Home Size	Tank	Media Amount	Capacity (Grains)	Price
1–3 Bathrooms	9" × 48"	1.0 cu ft	32,000	$2899.00
3–4 Bathrooms	10" × 54"	1.5 cu ft	48,000	$3419.00
5–6 Bathrooms	12" × 52"	2.0 cu ft	64,000	$4119.00

Selecting the ideal system size depends on your home’s bathroom count and water usage, ensuring you get the perfect balance of capacity and treatment power for your household.

How the media works

The secret to eliminating radon from your water lies in the large-bed granular activated carbon (GAC) media. This media acts like a highly absorbent sponge, capturing radon particles deep within its granules before they have a chance to escape as gas into your home’s air. The media’s large bed provides ample surface area for this capture process, and combined with the deep carbon tank design, it allows for maximum contact time between water and media. This ensures radon is trapped efficiently and safely, reducing overall radon levels in your water supply. The result is cleaner water and a safer indoor environment.
