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 hydrogen sulfide: no rotten-egg smell
- Stops black staining on fixtures and silverware
- Daily automatic backwash keeps the bed clean
- Air injection oxidizes iron, manganese and sulfur with plain air, so no chemicals or chlorine are added

Packaged for parcel delivery, the CS AIO 10"x44" Sulfur System brings 's Connected Series AIO™ Plus odor control to homes plagued by hydrogen sulfide. The air-injection process oxidizes the rotten-egg-smelling gas so it can be filtered out and rinsed to drain, restoring fresh, odor-free water without continuous chemical feed. Its compact, parcel-ready build is ideal for smaller homes and DIY installers who want easy handling.
This smart system connects over Bluetooth to the free Legacy View app, letting you set and monitor operation from an iPhone or Android™ phone. The AIO Plus valve provides independently programmable air-draw and backwash cycles, allowing a daily air refresh without an added backwash to conserve water, and it eases the air charge out slowly to protect the drain line from the blast common on older units. The 10" x 44" build includes the Connected Series Air Draw Meter Control Valve, bypass valve, black polyglass mineral tank, and the sulfur-reduction media and support bed.

Its compact footprint and parcel-ready packaging make this a practical choice for smaller homes and installers dealing with moderate sulfur odor. In operation the valve draws a daily air pocket, oxidizes the incoming hydrogen sulfide, and backwashes the bed to drain on a metered schedule. Add plumbing connections separately to match your piping, and consider the optional chrome tank jacket for visible installations. The result is a chemical-free, app-controlled solution to sulfur odor in well water.
Because the system oxidizes hydrogen sulfide on contact and flushes it during backwash, there is no chlorine feed to manage and no carbon to replace on a tight schedule. The Legacy View app shows system status at a glance and allows fine-tuning of air-draw and backwash timing to match your well. Packaged for parcel delivery, the unit ships easily to rural addresses, and the included bypass valve makes installation and seasonal isolation straightforward for the do-it-yourself owner.
