ABSTRACT:
A double valved snorkel has an inlet tube with a mouthpiece intermediate the upper and lower ends of the inlet tube. An inlet valve is positioned adjacent to the upper end of the tube and admits air into the inlet tube upon a suction force being applied to the mouthpiece. A repository is positioned adjacent an exit valve at the lower end of the tube. A drain basin is positioned in the inlet tube above the mouthpiece and diverts moisture inside the tube toward the repository. Since the repository is adjacent the exit valve below the mouthpiece, all moisture in the repository is expelled through the exit valve when a swimmer or diver exhales through the mouthpiece.
