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

This parcel-shippable CS AIO 13"x54" Sulfur System brings 's high-capacity Connected Series AIO™ Plus odor control to homes with significant hydrogen sulfide, packaged for convenient delivery. The 13" x 54" tank handles larger households, and air injection clears the rotten-egg smell without any continuous chemical feed. The parcel-ready build eases handling of this larger system for installers and DIYers.
The Connected Series valve pairs over Bluetooth with the free Legacy View app for iPhone and Android™, making programming and monitoring straightforward. Independently programmable air-draw and backwash cycles let you refresh the air pocket daily without a separate backwash to conserve water, while a gentle release of the air charge protects the drain line from the surge common on older units. Included are the Connected Series Air Draw Meter Control Valve, bypass valve, black polyglass mineral tank, and the sulfur-reduction media and support bed.

Air injection oxidizes hydrogen sulfide into a filterable form that is rinsed to drain, leaving water fresh without chlorine. The high-capacity tank suits demanding installations, while the parcel-ready packaging eases handling and delivery. In service the valve draws a daily air pocket, oxidizes the gas, and backwashes the bed to drain on a metered schedule. Add plumbing connections separately to fit your piping, and consider the optional chrome tank jacket for visible installations.
This parcel-ready 13" x 54" sulfur filter brings high-capacity odor control to large rural homes without the logistics of freight delivery. Its deep bed handles stronger sulfur and higher flow, while air injection removes the gas rather than masking it. The metered valve and daily air-draw cycle keep the system efficient, and the Legacy View app makes setup and ongoing tweaks a smartphone task. Included media, support bed, and bypass valve help installers complete the job quickly and cleanly. For demanding rural homes, the result is dependable, chemical-free odor control with the capacity to keep up and the smart features to make ownership effortless.
