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.

Abstract: An offset adapter includes a body having front and rear walls, and a body channel. An inlet portion has first and second ends, and an inlet channel extending from the first end to the second end and in fluid communication with the body channel. An outlet portion has first and second ends, and an outlet channel extending from the first end to the second end and in fluid communication with the body channel. A first recess is formed in the front wall of the body proximate a top of the body and opposite the inlet channel, with a surface of the first recess being forward of the body channel. A second recess is formed in a top of the body forward of the second end of the inlet portion; and a third recess is formed in a bottom of the body rearward of the first end of the outlet portion.
