That unmistakable stench of rotten eggs lurking in your water isn't just unpleasant—it’s a sign of hydrogen sulfide gas contaminating your supply. This sulfur smell seeps into showers, sinks, and appliances, turning daily routines into discomfort and forcing you to mask the odor with air fresheners or bottled water. Beyond the nuisance, it can corrode plumbing, damage fixtures, and put your family’s well-being at risk if left untreated.

The system that fixes it

The Pentek Rotten-Egg Sulfur Smell System is engineered precisely to eliminate the offensive sulfur odor at its source. At the heart of this solution is the Pentek-series air-injection control valve, a sophisticated head valve designed to inject air into the water to oxidize hydrogen sulfide efficiently. This genuine, serviceable brand valve is key to consistent performance and easy maintenance, ensuring your system operates optimally year after year. The system is built around a robust air-injection oxidizing tank that houses the Katalox Light oxidizing media — a powerful workhorse that transforms the hydrogen sulfide gas into a harmless solid. These solids are then flushed cleanly to the drain, cleansing your water continuously.

• Air-injection control valve: Precisely meters air for optimal oxidation, maintaining system longevity and efficiency.
• Air-injection oxidizing tank: Durable tank designed to withstand pressurized oxidation cycles without failure.
• Katalox Light media: Advanced oxidizing media specialized in neutralizing hydrogen sulfide gas.

How the media works

Katalox Light oxidizing media is the powerhouse inside the tank that makes this system effective. When water containing hydrogen sulfide gas enters the tank, the Pentek air-injection control valve introduces air into the water stream. This air oxidizes the hydrogen sulfide, converting it from a dissolved gas responsible for the rotten-egg smell into a solid sulfur particle. The Katalox Light media captures these solid particles, and during backwash cycles, the system flushes these trapped solids safely to the drain. This process continuously removes the sulfur compounds and prevents them from lingering in your water, ensuring the smell is gone and stays gone.
