FAQ

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

A: The Z6003AV-EWS is designed to work with most standard urinals rated for 0.5 gpf operation. Before installation, it's important to verify your fixture manufacturer's minimum flow requirements to ensure proper evacuation. The valve operates optimally between 10 and 100 psi water pressure, with a recommended minimum of 25 psi for proper fixture evacuation. If your fixture requires more flushing power, consider the Z6003AV-WS1 model which provides 1.0 gpf while still offering significant water savings compared to older 1.5-3.0 gpf models.

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

A: The Z6003AV-EWS 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, or 91,250 gallons annually when replacing an older 3.0 gpf valve. The dual seal diaphragm with triple filtered by-pass also prevents water waste from leakage, further enhancing water conservation.

Detailed Features & Benefits

Advanced Diaphragm Technology: The Z6003AV-EWS utilizes Zurn's AquaVantage TPE diaphragm with dual seal design and triple filtered by-pass. This chloramine-resistant construction prevents premature deterioration in treated water supplies, while the triple filtered by-pass protects against debris that can cause malfunction. The result is consistent water delivery and reliable shut-off, minimizing maintenance requirements and extending the service life of the valve.

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 with one-piece hex coupling nut 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.

Durable, Vandal-Resistant Design: Constructed from proprietary dezincification-resistant low lead brass alloy, the Z6003AV-EWS is built to withstand the rigors of commercial restroom environments. The vandal-resistant stop cap prevents unauthorized adjustments, while the ADA-compliant handle with non-hold open and no leak features ensures reliable operation for all users. The polished chrome finish not only provides an attractive appearance but also offers excellent resistance to corrosion and wear.
