Content: A primary second stage is one of two second stages on a standard open-water-style regulator. Unless there is an emergency, a diver breathes from this primary second stage during a dive. 1. Purge Button
The purge button is located on the face of the regulator second stage. The purpose of the purge button is to flood the second stage with air, forcing water out of the second stage. Divers use the purge button when the second stage has been allowed to fill with water--for example, when a diver removes the regulator from his mouth during the regulator recovery skill . 2. Ease of Breathing Adjustment
Most regulators have a lever or knob that allows divers to adjust breathing resistance. This feature helps to prevent regulator free flow (a state when air flows rapidly out of the regulator second stage without the diver breathing from it), which typically occurs when the breathing resistance has been lowered too much. A free flow can quickly empty a tank.
