回答“Why is my finished soda flat?”Make sure you are using water and not previously flavored liquids. If you would like extra fizzy soda, begin with carbonated water.
回答“Why is the lever not moving?”Make sure the bottle is inserted correctly. The bottle should be inserted and then pushed back, it does not screw in. Also, the nozzle tab may be in the incorrect starting position. The tab should start angled away from the bottle.
