That unmistakable rotten-egg sulfur smell lingering every time you turn on the tap isn’t just unpleasant—it’s a warning sign. This foul odor, often caused by hydrogen sulfide gas in your water, can permeate laundry, stain fixtures, and leave your entire home feeling unclean. Ignoring it risks corrosion, plumbing damage, and a constant assault on your family’s comfort and well-being.

The system that fixes it

The Fleck Rotten-Egg Sulfur Smell System is engineered specifically to eliminate that pervasive sulfur odor at the source, restoring fresh, clean water throughout your home. At its heart is the Fleck 2510 SXT air-injection control valve — a sophisticated head valve that introduces oxygen into the system to harness the natural power of oxidation. This valve precisely manages the air-injection process, ensuring hydrogen sulfide gas converts into a harmless solid form that’s then flushed away. Paired with a rugged oxidizing tank built for durability and filled with advanced Katalox Light media, this system actively transforms smelly contaminants into a clean, odor-free flow, protecting your home and your family from the costs and discomfort of untreated water.

• Fleck 2510 SXT air-injection control valve ensures precise air dosing for effective oxidation of sulfur compounds.
• Durable oxidizing tank designed specifically for air-injection applications, built to last and resist corrosion.
• Katalox Light media actively captures and converts hydrogen sulfide gas to solid particles, eliminating odor.
• Automatic flush cycles cleanse the media bed, flushing contaminants safely down the drain without user intervention.
• Genuine Fleck valve offers serviceability and reliability unmatched by generic alternatives, reducing downtime and maintenance headaches.

How the media works

At the core of this system’s success is the Katalox Light oxidizing media. This special material uses oxygen introduced by the air-injection valve to chemically react with hydrogen sulfide gas dissolved in your water. This reaction converts the smelly gas into a solid form that accumulates on the media bed. During regular automatic flush cycles, the system rinses the bed, flushing these solids harmlessly down the drain. This continuous cycle keeps your water free from sulfur odors without adding chemicals or requiring manual cleaning.
