Honest Water Co well water system — softening tank plus a Katalox Light tank for iron and sulfur

Whole Home Systems

Dual Tank — Well Water

Built for iron, sulfur and that rotten-egg smell.

Well water is a different problem from city water. This system pairs a softening tank with a Katalox Light tank to pull out iron, manganese and hydrogen sulfide — the cause of the smell, the orange staining and the metallic taste. Two ProValves, one per tank.

Best for: Homes on a private well

From people who had one installed

Great customer service. Corey explained in great detail exactly what a water softener and filtration system does and the benefits of having one. Pete and his team did an oustanding job installing the system. I am absolutely satisfied with the final product. Totally recommending Honest Water Co., to my friends.
