FAQ

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

A: The Z6203-WS1-YB-YC is designed to work with most standard urinals, including older fixtures that may require the full 1.0 gpf flow rate for proper evacuation. The valve operates effectively with water pressure from 10 to 100 psi, with a recommended minimum of 25 psi. The 1.0 gpf flow rate provides excellent performance across a wide range of urinal fixtures, making it an ideal choice for retrofit applications.

Q: How does this piston-operated valve differ from diaphragm valves?

A: Piston-operated flush valves typically offer more consistent performance in varied water conditions and can be more resistant to harsh water environments. The filtered by-pass design helps prevent clogging issues that can affect performance, and the chloramine-resistant seals provide extended service life, particularly in municipal water systems that use chloramine treatment.

Detailed Features & Benefits

Advanced Piston Technology: The Z6203-WS1-YB-YC utilizes Zurn's Metroflush piston technology with a clog-resistant filtered by-pass. This design prevents debris from affecting the valve's operation while providing consistent water delivery and reliable shut-off. The chloramine-resistant seals protect against premature deterioration in treated water supplies, extending the service life of the valve and minimizing maintenance requirements.

Optimal Flushing Performance: The 1.0 gpf flow rate delivers the ideal balance of water efficiency and flushing power for most commercial urinal applications. This flow rate ensures complete bowl cleaning and waste removal while still conserving water compared to older, less efficient models. The high back pressure vacuum breaker ensures reliable operation and prevents backflow contamination, while the control stop can be easily adjusted to fine-tune performance.

Exposed Installation Ready: The valve comes complete with a sweat solder kit (YB) and cast wall flange with set screw (YC), making installation straightforward for both new construction and retrofit applications. The exposed installation design offers easy access for maintenance and adjustments, reducing service time and costs throughout the product's lifecycle. The standard ADA-compliant handle ensures comfortable operation for all users.
