Sloan has released a new maintenance guide for the replaceable components on all manual, hardwired and battery powered flushometers. This guide is to be used as a reference to show the life expectancy (Sloan standard vs. industry standard) of the various replaceable parts. This is intended to be used as a reference guide only, as numerous external factors all also contribute to the life span of each component. Please see link below to the maintenance guide and use this a guideline to maintaining your existing flushometers moving forward:
