Master Rebuild Kit: Fits Sloan Brand, For Sloan, 3.5 GPF Size, 3.5 gpf Gallons per Flush

Toilet flush-valve diaphragm repair parts are kits for replacing diaphragm-type assemblies within a 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 toilet 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.
