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

How it ships: direct to you, free in the USA, in more than one box: the valve, the mineral tank, and the gravel and media in bags. You (or your plumber) pour the gravel and media into the tank and thread the valve on before installing. It usually takes 20 to 30 minutes, and step-by-step instructions are included.
For homes with heavier iron loads or higher water demand, the 5600 AIO 12X52 Iron System steps up both tank size and media volume to keep pace. This 12" x 52" air injection filter removes dissolved iron from well water without any salt or chemicals, protecting plumbing, appliances, and fixtures from the rust-colored staining that iron-laden water causes throughout a household.
The air injection process is straightforward and dependable: a pocket of air oxidizes incoming iron, the media bed captures the precipitated particles, and the Fleck 5600SXT control valve triggers an automatic backwash that flushes everything to drain. There are no feed pumps, no potassium permanganate, and no recurring chemical purchases, which keeps long-term ownership simple and affordable for the average homeowner.

Best Fit
The 12-inch diameter increases the system's service flow rate and treatment capacity, making it well suited to larger households or wells with more pronounced iron problems and multiple bathrooms running at once. Installed at the point of entry, it delivers clean, stain-free water to every faucet, appliance, and fixture in the home. Supplied complete by Water Softener Plus, this AIO system pairs proven 5600SXT automation with a robust mineral tank for years of low-maintenance, chemical-free iron control.
Routine ownership is refreshingly simple: with no salt or chemicals involved, there are no consumables to restock between regenerations. Over many years the media will eventually exhaust and can be replaced to restore full capacity, but the tank, valve, and bypass continue to serve. Confirming your incoming pH and iron level at setup helps ensure the oxidation process works as intended and that you get clear, stain-free water from day one.
From the control valve to the media bed, every part of this Water Softener Plus system is selected to work together reliably, so once it is installed and dialed in you can simply enjoy the improvement in your water without thinking about it.
