How it works
The valve draws a pocket of air into the top of the tank. Water passes through the air, which oxidizes iron, manganese and hydrogen sulfide into particles, and the media bed filters them out. Every day the valve backwashes the bed, sends the trapped particles to drain and refreshes the air pocket.
Media benefits
- Removes iron, manganese and hydrogen sulfide (rotten-egg smell) in one tank
- Handles high flow rates in a compact tank
- Long media life
- Backwashes the trapped particles to drain automatically
- Air injection oxidizes iron, manganese and sulfur with plain air, so no chemicals or chlorine are added

Air injection supplies the oxidation Katalox-Light® needs to convert dissolved metals into filterable solids, eliminating the need for chlorine or potassium permanganate. This high-capacity build is ideal for larger homes battling combined iron and manganese staining along with sulfur odor in a single tank. The metered valve draws a daily air pocket, oxidizes the contaminants, and backwashes the bed to drain as water use requires. Choose plumbing connections separately, and add the optional chrome tank jacket for a polished appearance.
Rated at 80,000 grains, this high-capacity Katalox-Light® system is built for larger homes whose wells combine iron, manganese, and sulfur in challenging amounts. Consolidating that treatment into one deep-bed tank simplifies both the installation and the homeowner's experience compared with chaining multiple single-purpose filters. The metered Connected Series valve, daily air-draw cycle, and Legacy View app together deliver comprehensive, chemical-free treatment with the efficiency and remote control that modern households expect. Consolidating iron, manganese, and sulfur treatment into one high-capacity tank also keeps the mechanical room uncluttered and the homeowner's maintenance routine simple.
