The Z6000AV-WS1-DF delivers dual-flush performance for water closets in commercial restrooms. Engineered with AquaVantage® technology and a diaphragm-operated design, it offers both water-saving and full-flush options in a single valve. Ideal for facilities seeking EPA compliance and flexible flushing control.

Key Specifications:

• Flow Rate: Dual flush — 1.1 gallons per flush (reduced) and 1.6 gallons per flush (full).
• Operation: Manual flush with ADA compliant dual-flush handle.
• Construction: Chrome-plated brass body with chloramine-resistant internal seals.
• Dimensions: 11-1/2" overall valve height; top spud connection.

Features & Benefits:

• Dual Flush Efficiency: The valve offers two flush volumes, allowing users to choose between a reduced 1.1 gpf and a full 1.6 gpf flush. This flexibility helps conserve water during light usage while still providing full evacuation when needed.
• Durable Build: Constructed from dezincification-resistant brass and finished in polished chrome, the valve resists corrosion and wear in demanding environments. The vandal-resistant stop cover adds protection in public or high-traffic restrooms.
• Consistent Performance: Zurn’s AquaVantage® diaphragm includes a clog-resistant triple-filtered bypass that maintains reliable flushing even with variable water pressure. This ensures smooth operation and reduces maintenance calls due to inconsistent flow.
• Installation Flexibility: The adjustable tailpiece and included sweat solder kit simplify alignment and connection during setup. The cast wall flange with setscrew provides a secure and professional finish that accommodates different wall depths.
• Backflow Protection: The high back pressure vacuum breaker prevents contaminated water from re-entering the supply line. This feature is essential for meeting plumbing codes and maintaining sanitary conditions in commercial restrooms.

FAQ

Q: How does the dual-flush handle work?

A: The Z6000AV-WS1-DF features a two-position handle: a downward push activates the full 1.6 gpf flush, while an upward lift triggers the reduced 1.1 gpf flush. This allows users to choose based on need, helping conserve water without sacrificing performance.

Q: Is this valve compatible with standard water closets?

A: Yes. The Z6000AV-WS1-DF is designed for top spud water closets rated for 1.6 gpf and 1.1 gpf operation. It performs reliably with water pressure between 10 and 100 psi. Always confirm your fixture’s flow rating before installation.
