Manual Closet Flush Valve
What is this?
This is a high-performance, manual flushometer designed for commercial floor-mounted or wall-hung top spud toilets. As part of a legacy series that has led the industry for over a century, this valve is the gold standard for durability and water efficiency in high-traffic restrooms.
What does it do?
-
Precise Water Delivery: Equipped with dual-filtered fixed bypass technology, this valve ensures a consistent flush volume every time, regardless of water pressure fluctuations.
-
Vandal Resistance: Features a free-spinning stop cap and a robust, metal oscillating handle that is ADA-compliant. The non-hold-open design prevents the toilet from exceeding its intended water usage if the handle is held down.
-
Chloramine Resistance: The internal diaphragm, handle packing, and vacuum breaker are molded from high-quality synthetic rubber, protecting the valve from the harsh chemicals often found in municipal water supplies.
-
Quiet Performance: Engineered for "quiet" operation, it minimizes the noise of rushing water, making it ideal for professional office buildings, schools, and hospitals.
Will it fit my sink?
This flush valve is designed for standard commercial toilet installations with a 1-1/2" top spud connection and a 1" IPS supply pipe. It is the ideal choice for new construction or as a direct replacement for existing diaphragm-style flushometers. If you are maintaining a facility that requires heavy-duty, reliable plumbing hardware, this valve is the industry benchmark.
