Sloan A1038A Repair Kit, Diaphragm, 3.5 GPF

Toilet flush-valve diaphragm repair parts replace broken or worn diaphragm-type assemblies and parts within a flush valve (flushometer) to restore proper flushing and sealing. Diaphragm assemblies regulate pressure inside the valve using a flexible rubber disc (diaphragm) that seals the valve seat after each flush. Diaphragms that becomes worn or warped may either stick in place to prevent flushing or fail to seal so that the toilet keeps running.
