Mountain Water Co.
A Mountain Water Co. dual-tank system: a softening tank, a carbon tank and a brine tank

Whole Home Systems

Dual-Tank System — City Water

A softening tank and a carbon tank, each doing one job.

Two tanks instead of one: a dedicated softening tank and a dedicated carbon tank. Splitting the media means each does its job properly instead of competing for room in a single vessel. Worth it on larger houses and on supplies with a strong chlorine taste.

Best for: Larger homes, or a strong chlorine taste on a town supply
