The complete Zenith specification for everyday homes
Smarter regeneration from the bottom up
Brine moves upward through the resin bed, concentrating cleaning where the resin works hardest. The upflow configuration is designed to use salt and water efficiently while maintaining reliable softening performance.
More durable media for city water
Zenith uses 10% cross-linked ion-exchange resin rather than the common 8% standard. Its denser structure is more resistant to chlorine and chloramines and supports dependable long-term operation.
Regenerates only when your home needs it
The control valve monitors actual household water use and regenerates on demand instead of relying on a fixed timer. Proportional brining uses only the salt required for each cycle.
Helps control condensation around the tank
Every Zenith softener includes an insulating jacket to reduce surface sweating, help protect the control head from persistent moisture and limit standing water around the system. The jacket is not freeze protection.
Fixing hard water pays off in everyday comfort
Ion exchange removes the calcium and magnesium that leave scale, spotting and residue throughout the home.
Less scale
Helps reduce new hardness scale on fixtures and inside plumbing and water-using appliances.
Cleaner surfaces
Fewer mineral spots and less soap residue make kitchens and bathrooms easier to maintain.
Better washing
Soap, shampoo and detergent can lather and rinse more effectively in softened water.
Every-tap comfort
Enjoy consistently softened water throughout your home from a system sized to your needs.
One series. Three live capacities. The right fit is tested, not guessed.
Both Zenith series are available in 32,000-, 48,000- and 64,000-grain models, in either single or Dual Tank configurations. Final sizing is confirmed after testing your water and reviewing household demand.
Sizing guidance is indicative only. Hardness, occupancy, well water, and high-flow fixtures can change the recommendation. Grain capacity is a nameplate rating at the maximum salt dose; actual capacity per regeneration is lower with Zenith’s efficient salt settings.
Same capacity range. Different tank technology and warranty.
Essential and Performance are not a small-to-large ladder. Both series come in every live size; Performance adds Vortech™ tank distribution and longer parts coverage.

Grain capacity is a nameplate rating measured at maximum salt dose. Zenith uses proportional brining at efficient salt settings, so capacity per regeneration is lower and salt use is correspondingly lower. Service flow is a guideline and varies with water conditions and pressure. The current 80k model is not yet offered or published as a live product.

Frequently Asked Questions
Zenith technicians handle placement, plumbing connections, programming, performance checks, and a clear handover for your household.
What does a Zenith water softener remove?
It removes dissolved calcium and magnesium – the minerals responsible for hard water and scale. A softener does not remove chlorine, chloramine, taste, odor, iron staining or bacteria.
How is the correct system size selected?
Zenith confirms sizing during a free in-home water test using your measured hardness, household size, daily use and peak-flow needs. The size guidance on this page is indicative only and should not be used as a self-service selector.
What is upflow regeneration?
During regeneration, the system draws brine upward through the resin bed. This concentrates cleaning where the resin works hardest and supports efficient salt and water use.
How much salt can the system save?
A correctly configured Zenith system can use up to 50% less salt than a standard time-clock softener. Actual use varies with water hardness, household demand, system size and settings.
What is the difference between single and Dual Tank?
A single-tank system regenerates during a scheduled low-use period. A Dual Tank system alternates between two resin tanks, so one remains in service while the other regenerates for continuous soft water.
Is the insulating jacket freeze protection?
No. The included tank jacket helps control condensation and moderate temperature swings, but it does not prevent freezing and must not be treated as freeze protection.
Does a softener purify drinking water?
No. Softening and filtration are different treatments. A softener removes hardness minerals; it is not intended to treat chlorine, taste, odor, bacteria or unrelated contaminants.
What happens during the free water test?
A Zenith water specialist measures your hardness, reviews household demand and plumbing, confirms installation clearances, then recommends the appropriate series, size and configuration with clear pricing.
