ZURN Urinal Flush Valve Repair Parts & Accessories

Urinal flush-valve diaphragm repair parts are kits for replacing diaphragm-type assemblies within a urinal flush valve (flushometer) to restore proper flushing and sealing. The diaphragm assembly regulates pressure inside the valve using a flexible rubber disc (diaphragm) that seals the valve seat after each flush. A diaphragm that becomes worn or warped may either stick in place to prevent flushing or fail to seal so that the urinal keeps running. Also known as a retro kit, inside parts kit, or drop-in-kit, these kits include a new diaphragm as well as other parts of the assembly that may need replacing to complete the repair.
