ABSTRACT:
A water intake prevention device for a snorkel includes an outer housing that is affixed to the airway tube of a snorkel. The outer housing includes a plurality of inlet openings to allow the intake of air. An inner housing of the device includes a float that moves in an interior of the inner housing. When a diver drops to a depth at which the snorkel is underwater, water flows into the air inlets. The water raises the float within the interior of the inner housing, so that a tapered upper end of the float seals an airway opening, thereby preventing the flow of water through the airway. The inlet openings of the outer housing must be below and isolated from the airway opening in the inner housing and isolated from the airway of the snorkel.
