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

Chemical-Free Iron Control
The system uses air injection oxidation to treat iron without salt or chemicals. An air pocket in the tank converts dissolved iron into a solid, filterable form, which the deep media bed captures and holds. Control Flow Technology meters regeneration to real household water use, so the system backwashes only when needed — flushing iron to drain and renewing the air cushion. There are no feed chemicals or potassium permanganate to maintain or replenish.
The large 14-inch diameter and 65-inch height supply the highest service flow in the residential iron range, ideal for large or multi-bath homes and wells with heavy iron staining. Installed at the point of entry, it guards plumbing, appliances, and fixtures against rust buildup throughout the home. Supplied by Water Softener Plus, this configuration arrives nearly complete; add the plumbing adapters that fit your setup for a clean install and dependable, low-maintenance iron control.
For best results, plan the installation near the point where water enters the home, ahead of any softener or under-sink filtration, so iron is removed before it can foul downstream equipment. A nearby drain is needed to carry away backwash water, and a standard electrical outlet powers the control head. Once commissioned, the system runs on its own schedule, and a quick periodic glance at the valve display is typically all the attention it requires from the homeowner.
Whether you are upgrading aging equipment or treating a new well for the first time, this system from Water Softener Plus offers a proven, low-fuss path to cleaner water, backed by the trusted engineering behind every component in the package.
