pressure opens the other exit that is a check valve allowing the water to fill an air tight chamber (see figure 2). As the chamber fills with water the air in the chamber compresses. When the water pressure and air pressure are equal the pressure switch valve no longer is pushed open by water flow and shuts. At this point two things happen.
