FAQ

Q: Will this flush valve work with my existing urinal fixture?

A: The Z6003-EWS-YB-YC is designed to work with most standard urinals rated for 0.5 gpf operation. The valve operates effectively with water pressure from 10 to 100 psi, with a recommended minimum of 25 psi for proper fixture evacuation. Before installation, it's important to verify your fixture manufacturer's minimum flow requirements to ensure proper evacuation.

Q: How much water can I save by switching to this flush valve?

A: The Z6003-EWS-YB-YC operates at 0.5 gallons per flush, which can reduce water consumption by up to 50% compared to standard 1.0 gpf models and up to 85% compared to older 3.0 gpf models. In a typical commercial setting with 100 uses per day, this can translate to savings of approximately 18,250 gallons of water annually when replacing a standard 1.0 gpf valve.

Detailed Features & Benefits

Advanced Diaphragm Technology: The Z6003-EWS-YB-YC utilizes Zurn's Aquaflush diaphragm technology with a clog-resistant by-pass. This design prevents debris from affecting the valve's operation while providing consistent water delivery and reliable shut-off. The chloramine-resistant dual seal diaphragm protects against premature deterioration in treated water supplies, extending the service life of the valve and minimizing maintenance requirements.

Precision Engineered Water Delivery: The 0.5 gpf flow rate is precisely calibrated to provide effective bowl cleaning while conserving water. The high back pressure vacuum breaker ensures reliable operation and prevents backflow contamination. The control stop features internal siphon-guard protection and can be easily adjusted to fine-tune the flow for optimal performance with your specific fixture and water pressure conditions.

Complete Installation Package: The YB-YC configuration includes both the sweat solder kit and cast wall flange with set screw, providing everything needed for a professional installation. The sweat solder adapter allows for secure connection to the water supply pipe, while the cast wall flange creates a finished appearance where the pipe extends from the wall. These components ensure a proper installation that looks clean and professional while meeting WaterSense requirements for sustainable building initiatives.
