Course Outline

Objective: Remove, replace, and clear a regulator underwater using the purge method.

Value: If you should need to remove the regulator from your mouth, or if it should become dislodged, you will need to be able to replace and clear it while you are underwater. The purge button method is used to remove all the water from the regulator if you have insufficient breath left to clear it with the blast method.

How It’s Done:

  1. Remove the regulator from your mouth, ensuring that the regulator mouthpiece faces down. This will minimize the chances of a freeflow. If you do accidentally forget and it does start to freeflow, simply turn the mouthpiece face down and the freeflow should stop.
  2. Maintain control of your airway by blowing small bubbles. Remember: Never hold your breath!
  3. Replace the regulator, and use the purge button to clear the excess water from the regulator.
