>1-Inch Lead-Free Whole-House Catalytic Water Conditioner

The Zilmet ZAF010 ActivFlo 1" (MPN: ZAF010) is a salt-free, chemical-free inline water conditioner designed for 1-inch cold water main lines on small to mid-sized homes, protecting water heaters, plumbing fixtures, and household appliances from limescale buildup.

Key Features

Designed for Whole-House Point-of-Entry Protection

Engineered for installation on 1-inch main cold water service lines, delivering continuous scale prevention across all downstream fixtures, tankless heat exchangers, boilers, and appliances.

Catalytic Alloy Conditioning Technology

Utilizes an internal catalytic alloy core to transform dissolved calcium bicarbonate into stable, non-adherent aragonite micro-crystals that pass harmlessly through the plumbing system without forming scale.

Standard Household Flow Sizing (1.9 – 5.9 GPM)

Optimized for typical continuous domestic flow rates of 1.9 GPM to 5.9 GPM in 1-inch pipe configurations, providing consistent catalytic scale reduction without restricting volume.

Zero-Power & Maintenance-Free Passive Operation

Operates passively on line water pressure without requiring electrical connections, salt replenishment, chemical additives, or backwash drain lines—eliminating ongoing maintenance and water waste.

Compact Lead-Free Stainless Steel Housing

Constructed with a heavy-duty stainless steel body featuring standard 1-inch MNPT threaded ends and a compact 6-inch overall length for easy retrofit installation, backed by a 15-year warranty.

Zilmet ZAF010 FAQ

How does the Zilmet ActivFlo ZAF010 prevent limescale without salt?

As water passes over the internal catalytic alloy core, fluid shear and catalytic reaction alter dissolved calcium and bicarbonate ions into insoluble aragonite crystals. These tiny micro-crystals remain suspended in the water stream rather than sticking to heating elements, pipe walls, or fixture aerators.

What is the difference between the ActivFlo ZAF010 (ZILZAF010) and the High-Flo ZAF010H (ZILZAF010H)?

While both models feature 1-inch MNPT threaded connections for 1-inch pipe lines, they are engineered for different flow demands and system sizes:

• Flow Profile & Capacity: The standard ZAF010 (ZILZAF010) is optimized for standard household continuous flow rates of 1.9 GPM to 5.9 GPM. The High-Flo ZAF010H (ZILZAF010H) is built for higher-demand applications, supporting continuous flow rates from 5.9 GPM to 15.9 GPM with minimal pressure drop (0.5 PSI).
• Physical Dimensions: The ZAF010 features a compact 6-inch overall body length, making it ideal for tight retrofit spaces, whereas the ZAF010H features a larger 8.3-inch body to accommodate the higher internal volume.
• Application: The ZAF010 is best suited for small-to-average single-family homes on 1-inch mains. The ZAF010H is engineered for larger homes, high-demand multi-bathroom properties, or commercial branch lines requiring higher simultaneous flow capacity.

Where should the ZAF010 be installed?

It should be installed inline on the main cold water service line entering the home, downstream of the primary shutoff valve or backflow preventer, to condition water for the entire property.

Does this unit require regular maintenance or replacement media?

No. The ActivFlo operates entirely passively with no moving parts, non-sacrificial internal media, salt tanks, or electrical components, requiring zero routine servicing after installation.

Will the ZAF010 restrict my home's water pressure?

When operating within its recommended flow range of 1.9 to 5.9 GPM, the straight-through inline design causes negligible pressure drop across the system.
