When your well water reeks of sulfur, stains your fixtures with iron rust, or harbors bacteria that threaten your family’s health, you’re facing more than just an annoyance — you’re risking costly pipe damage, unpleasant odors, and compromised comfort every day. Total Well Chlorination is the targeted solution to these persistent hazards, eliminating the root causes before they infiltrate your home.

The system that fixes it

Introducing the Pentair Total Well Chlorination System, engineered to provide comprehensive water purification tailored to the challenges found in private well water. At its core, this system features the Pentair-series air-injection control valve — a precision-engineered head valve designed for reliable chlorination cycles and effortless serviceability. This valve injects controlled air to activate and optimize the chlorination process, ensuring consistent destruction of bacteria and oxidation of iron and sulfur. The system is built around a robust filtration and softening train housed in a durable tank, containing a carefully balanced blend of catalytic oxidizing media and softening resin. Together, these media work continuously with chlorination to remove iron, sulfur, and bacteria, while softening the water to prevent scale buildup. The result is clean, safe water delivered throughout your home, safeguarding your plumbing and enhancing your everyday living.

With Pentair’s system, your well water becomes a reliable resource rather than a source of frustration and expense.

How the media works

The secret to this system’s power lies in the catalytic oxidizing media combined with softening resin inside the tank. Catalytic oxidizing media uses a chemical reaction catalyzed by injected chlorination to convert dissolved iron and sulfur into solid particles easy to filter out. At the same time, the softening resin captures calcium and magnesium ions to reduce water hardness. This dual-action media setup continuously treats your water by working hand-in-hand with the chlorination process, ensuring that harmful contaminants are neutralized before they reach your taps. It’s a smart, efficient method that tackles multiple well water problems simultaneously, delivering water that’s not only cleaner but gentler on your home’s plumbing.
