Abstract

A flushometer system includes a pressure vessel with a flow path defined between a valve inlet chamber and an outlet and a valve assembly disposed within the pressure vessel and configured to selectively open and close the flow path. A primary diaphragm assembly is disposed within the pressure vessel and includes a primary disc configured to be moveable to actuate the valve assembly to selectively open and close the flow path between the valve inlet chamber and the outlet, and a primary diaphragm connected to the primary disc. A secondary diaphragm assembly is disposed within the pressure vessel and includes a secondary diaphragm and a secondary disc, the secondary diaphragm assembly configured to actuate the primary diaphragm assembly by venting fluid pressure on one side of the primary diaphragm. An activation assembly is configured to actuate the secondary diaphragm assembly by venting fluid pressure on one side of the secondary diaphragm.
