When a main valve (V1) is opened at a time point t1, control means opens an on-off valve (V2) to supply flush water from piping (12) to an ejector (50). When water flows in the ejector (50), the ejector sucks air in a negative pressure tank (30). Ejector discharge water that flows out of an outlet of the ejector (50) is lead into a water container (20), and air is separated in the water container (20) from the ejector discharge water.
