If your well water harbors harmful bacteria and coliform, your family’s health and your home’s plumbing integrity are at risk. Lingering foul odors, unexplained cloudiness, or recurring illnesses can be red flags that these invisible contaminants have invaded your water supply. Without prompt treatment, bacteria and coliform presence can lead to costly damage and serious health issues throughout your household.

The system that fixes it

The C-Series Bacteria & Coliform (Well) System is engineered specifically to combat bacterial contamination and coliform in well water, delivering spotless, safe water throughout your entire home. At its heart is the durable C-Series backwashing control valve, a sophisticated valve that manages automatic cleaning cycles and ensures consistent filtration performance without manual intervention. Unlike generic valves, this genuine brand valve is fully serviceable, meaning it can be maintained and repaired easily over time—ensuring long-term reliability without costly replacements.

The system features a robust whole-house contact and filtration tank designed for effective media exposure and flow distribution. Inside, a potent blend of KDF-55 and catalytic carbon serves as the working media. This unique combination actively suppresses bacterial growth and strips away chlorine and unpleasant odors, creating water that not only tastes and smells clean but is also safer to use. When paired with the UV stage available in our well water bundle, it forms a comprehensive disinfection solution that tackles microscopic threats head-on.

How the media works

The secret power lies in the system’s media blend: KDF-55 combined with catalytic carbon. KDF-55 is a high-purity copper-zinc alloy that works by creating an electrochemical reaction that inhibits bacteria growth and captures heavy metals, stopping them from multiplying or causing harm. Meanwhile, the catalytic carbon acts like a magnet for chlorine, bad odors, and organic compounds, chemically breaking them down so they vanish from your water. Together, this bacteriostatic duo suppresses bacterial reproduction without harsh chemicals, ensuring that what flows from your tap is clean, fresh, and safe.
