flush valves

Toilet release mechanisms

Flush valves are mechanisms that release a measured rush of water to clear waste from toilets and urinals.

Unlike tank-based systems that store water, flush valves connect directly to pressurized water supply lines, making them standard in commercial and public restrooms where frequent use demands quick recovery between flushes.

The flushometer—a common type—activates by handle or sensor.
