Overview
Softening every tap in the house from the point of entry is the job of this system, which swaps hardness minerals for sodium through ion exchange. A fiberglass tank, a separate brine tank and an LCD control head make up the unit, with a pre-filter ahead of it.
The case for it is a complete bundle: tank, valve head, pre-filter and install kit arrive together, and metered regeneration is claimed to use less salt and water than timer-based units. The limitation is its size and power draw, since it needs floor space at the main line and a nearby outlet.
Who it's for
A household of the rated size that is dealing with scale, spotted glass and stiff laundry and can place a large tank near the main line. A very large family, or water above the stated solids limit, needs a different system.
Pros and cons
- Complete bundle with install kit
- Pre-filter protects against rust and sediment
- LCD shows time and gallons remaining
- Certified for hardness reduction
- Needs floor space and outlet
- Hardness limit not listed
- Salt refills required
Performance notes
Hard water passes through resin beads that trap calcium and magnesium and release sodium, then the system regenerates with brine from the second tank. Metered operation triggers regeneration by actual water use instead of a clock, which is how the manufacturer claims savings on salt and water. The pre-filter removes rust and sediment before they reach the resin.
