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

The CS AIO 12"x52" Iron System steps up tank size for homes with higher water demand or stronger iron levels, while retaining the smart features of 's Connected Series AIO™ Plus platform. With a 12" x 52" tank rated at 64,000 grains, it provides the capacity larger residences need to stay ahead of rust staining across multiple bathrooms and water-using appliances.
Bluetooth control through the free Legacy View app lets you program and monitor the metered Connected Series valve from an iPhone or Android™ device. The AIO Plus valve offers independently programmable air-draw and backwash cycles, so the air pocket can be refreshed daily without an added backwash, saving thousands of gallons annually, and it releases the air charge slowly to protect the drain line. The system includes the Connected Series Air Draw Meter Control Valve, bypass valve, black polyglass mineral tank, and all media and support bed for iron reduction.

- Metered Connected Series Air Draw Control Valve with Bluetooth
- Free Legacy View app for iPhone and Android™
- Programmable air-draw and backwash cycles save water
- Media and support bed included for iron removal

Air injection oxidizes dissolved iron into filterable particles that are flushed to drain, keeping fixtures and laundry free of rust stains without chlorine or potassium permanganate. The larger tank suits bigger households and heavier iron loads, and the metered valve regenerates only as actual water use requires. Because the media and support bed are included, setup is mainly a matter of plumbing in the tank and programming the valve through the app. Choose plumbing connections separately, and add the optional chrome tank jacket for a finished look.
Rated at 64,000 grains, the 12" x 52" tank gives larger households the iron-removal capacity to keep up with busy schedules and multiple fixtures. The metered Connected Series valve regenerates on demand, so capacity is used efficiently rather than on a fixed timer. With the daily air-draw cycle reducing backwash frequency and the Legacy View app providing phone-based control, this configuration pairs strong performance with low water use and easy management for the modern home.
