When nitrate and nitrite levels climb in your well water, it’s not just a taste or odor issue — it’s a hidden hazard that can threaten your family’s health and devastate your home’s plumbing. Cloudy water, metallic flavors, and unexplained stains on fixtures signal these contaminants. Ignoring them risks costly repairs, compromised water safety, and discomfort that can ripple through every faucet.

The system that fixes it

The C-Series Nitrate & Nitrite (Well) System is engineered precisely to tackle the stubborn problem of nitrate and nitrite contamination at its source. Central to this water treatment powerhouse is the C-Series metered control valve, a sophisticated head valve that carefully measures water flow to optimize regeneration cycles. This means your system works efficiently, saving water and salt, while ensuring the media’s peak performance over time. The system's backbone is a specially designed ion-exchange tank built to house a nitrate-selective anion resin. This potent media excels at grabbing hold of nitrate molecules, even when sulfate levels spike, maintaining consistent water purity. The combination of smart control and robust tank design guarantees a long-lasting solution that keeps your home’s water clean and safe.

This system transforms your water into a safe, reliable resource you can trust daily.

How the media works

The heart of the system’s success lies in its nitrate-selective anion resin—a specialized ion-exchange material designed to target nitrate ions specifically. Think of it as a microscopic net woven to catch only nitrate and nitrite molecules from your water, removing them effectively and holding them securely until the resin is regenerated. Unlike generic resins, this media remains stable and efficient even when sulfates in the water rise, preventing breakthrough and ensuring consistent removal. This tailored approach means your water is purified precisely where it matters most, without interference from other minerals.

Common questions

Q? How do I know if nitrate and nitrite are a problem in my well water?
A Nitrate and nitrite contamination often reveals itself through cloudy water, unusual odors or metallic tastes, and sometimes visible staining on fixtures. Testing your well water is the only sure way to confirm levels and understand the risk to your household.

Q? Can the system handle fluctuations in sulfate levels commonly found in well water?
A Yes, the nitrate-selective anion resin is specifically designed to maintain performance and nitrate removal even during sulfate spikes, ensuring consistent water quality.

Q? How often does the system need maintenance or media replacement?
A Thanks to the C-Series metered control valve, regeneration is precisely timed according to water usage, extending media life. Regular maintenance intervals vary, but the genuine brand valve makes servicing simple and cost-effective.
