The term: upside down bong – meaning turn the bong upside-down such that the water can drain into the top chamber. Be sure to be mindful of the carb leaking water while you do this. (We suggest keeping the carb facing up, and tilting it at an angle)
While you’ve still upside down bong, turn the valve closed so it is completely horizontal. Once done, the water will be trapped in the top chamber, preventing it from falling below. Is in important step and you want to make sure you get the term right – upside down bong.
