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 dissolved iron: clear water with no orange or brown stains
- Protects fixtures, laundry, water heaters and appliances
- Daily automatic backwash sends the trapped iron to drain
- Air injection oxidizes iron, manganese and sulfur with plain air, so no chemicals or chlorine are added

This CS AIO 13"x54" Iron System is the parcel-shippable build of 's high-capacity Connected Series AIO™ Plus iron filter, packaged for convenient delivery. The 13" x 54" tank handles larger homes and heavier iron loads, oxidizing dissolved iron through air injection so it can be filtered out and rinsed to drain without chemical feed. The parcel-ready packaging eases handling of this larger system.
The Connected Series valve connects over Bluetooth to the free Legacy View app for iPhone and Android™, making programming and monitoring effortless. Independently programmable air-draw and backwash cycles let you draw a fresh air pocket daily without a separate backwash to save water, while the air charge is released gently to protect the drain line from the surge common on older systems. Included are the Connected Series Air Draw Meter Control Valve, bypass valve, black polyglass mineral tank, and the iron-reduction media and support bed.

By oxidizing iron into particles the bed can capture, the system keeps sinks, tubs, and laundry free of rust stains without potassium permanganate or chlorine. The high-capacity tank suits demanding installations, while the parcel-ready packaging eases handling for installers. In service the valve draws a daily air pocket, oxidizes incoming iron, and backwashes the bed to drain on a metered schedule. Add plumbing connections separately, and an optional chrome tank jacket is available to finish the installation.
Delivering high-capacity iron removal in a parcel-friendly box, this 13" x 54" filter suits large rural homes that prefer to avoid freight. The deep bed handles heavier iron loads, while the daily air-draw cycle keeps oxidation strong and conserves water between backwashes. The Legacy View app brings programming and diagnostics to a smartphone, so ongoing management is simple. For installers, the included media, support bed, and bypass valve make for an efficient, largely plug-and-play installation. The deep bed and smart controls together make this a future-proof choice for homes whose iron levels are high or expected to fluctuate with the seasons.
