An apparatus for detecting wear in a flush valve includes at least one programmed controller. The flush valve comprises at least one pressure sensor and a valve element, and operates when an internal pressure causes the valve element to open. The controller is programmed to record at least one water pressure detected within the flush valve with the at least one pressure sensor after at least one operation of the flush valve, record a water pressure detected within the flush valve after a subsequent operation of the flush valve, and determine if the flush valve is faulty based at least partially on a comparison between the at least one water pressure detected after the at least one operation of the flush valve and the water pressure detected after the subsequent operation of the flush valve.
