A method for determining the point in time for the replacement of one or more of wearing parts, blocking fluids and fragrance and cleaning substances, dependent on the use of a sanitary apparatus, includes the step of placing an indicator element in the run-out region of the sanitary apparatus, which indicator element has an optically recognizable chemical or physical conversion indicator that provides an observable conversion after a predetermined, or pre-set, number of uses, or wettings, of the sanitary apparatus for altering maintenance personnel that maintenance of the sanitary apparatus is required. An apparatus for performing the method is also provided.
