Toilet Flush Valve Repair Parts & Accessories

18 products

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.

Toilet Flush Valve Piston Repair Parts

Toilet flush-valve piston repair parts replace piston-type assemblies within a flush valve (flushometer) to restore proper flushing and sealing. The piston assembly regulates pressure inside the flushometer using a cylinder with a sliding cup seal that seals the valve seat after each flush. Signs that the piston assembly may need replacement or repair include a toilet that won't flush, keeps running, or has a flush that's too short or too long.
