text: Another problem with the Finis snorkel is that small amounts of accumulated water cannot be released because the water purge valve located below the mouth piece will not open during forceful exhalations due to the wide diameter of the breathing tube required for inhalation, and the water purge valve will only open when water has accumulated along the lower portion of the breathing tube up to the level of the mouthpiece, at which point an exhalation more forceful than normal combines with the downward pressure of the accumulated water to produce enough pressure to open the water purge valve to release most of the accumulated water.
