Toilet flush-valve handle and push-button repair parts are components for replacing the lever or button flushing mechanisms used on manual flush valves (flushometers). Handle or push-button assemblies may need replacing when they leak, sag, or no longer activate flushing.,Toilet flush-valve repair parts and accessories allow individual components of a commercial flush valve (flushometer) to be replaced rather than the entire valve assembly. They're used for routine maintenance and repair of tankless-toilet flush valves, which are commonly found in high-use (more than 30 flushes per day) public, commercial, and institutional restrooms. Signs that a flushometer may need repair include leaking from the valve, water splashing from the bowl during flushing, and toilets that keep running. These toilet flush parts are designed specifically for flush valves and often fit only specific brands or models.
