Iron, Sulfur & Odor Well System — Air-Injection (Chemical-Free)
The problem
Is your well water causing stubborn rust stains and a persistent rotten-egg smell? Iron and hydrogen sulfide in your water can leave unsightly reddish-brown stains on tubs, toilets, and fixtures, while sulfur's rotten-egg odor makes every tap unpleasant. Hardness compounds these issues, leading to dry skin, dull hair, and scale buildup that shortens appliance life.
Without effective treatment, these contaminants degrade your home's plumbing and water quality, impacting your family's comfort and health daily.
How it works — the air-injection iron filter that fixes it
The system’s first stage uses chemical-free air-injection technology to oxidize and remove dissolved iron and hydrogen sulfide. Air is injected into the water, causing iron to oxidize into solid particles that the filter traps, while sulfur compounds break down and are filtered out—eliminating the rotten-egg smell without salt or chemicals.
Next, the Fleck 5600SXT metered water softener uses ion exchange to remove hardness minerals, preventing scale buildup and improving water softness. Finally, an under-sink reverse osmosis (RO) system delivers bottled-quality drinking water by filtering out residual contaminants—ensuring pure, clean water right at your kitchen tap.
What it handles
Built for Whole-house well combo
This system is specifically engineered for homes drawing water from wells with moderate iron, sulfur odor, and hardness. The chemical-free air-injection filter addresses both iron staining and that pervasive rotten-egg smell, something many well users struggle to eliminate without harsh chemicals.
By combining this with a genuine Fleck metered softener and finishing with an under-sink RO drinking water system, you receive a full home treatment train that covers every water need—whole-house filtration and premium drinking water—perfect for well water challenges where multiple contaminants affect comfort and health.
Built on a genuine Fleck valve — not a disposable clone
This system runs on a Fleck control valve — the industry-standard brain of the system. Its parts are stocked by water dealers nationwide and stay available for decades, so a worn seal or piston is a quick, low-cost rebuild — never a throwaway. For a Whole-house well combo where downtime is expensive, that serviceability is the whole point. We never build on unbranded clone heads that strand you when they fail.
Genuine, serviceable, warrantied — a system you keep for 15 years instead of replacing in four.
