What if the regulator fails when diving?

What if the regulator fails when diving? At present, there are few failures of regulators, but everything should be prepared in one hand, just in case. What if the regulator fails when diving?

When your regulator fails due to long-term cleaning and maintenance or for any reason and starts to leak a lot, you can now have several solutions:

1. Turn down the mouthpiece, press the _ gas button of the regulator several times, or adjust the adjustment button to reduce the gas output of the regulator.

If this still can't stop the regulator from leaking a lot, then you must change the following measures.

2. Switch to your own standby auxiliary head.

3. Find a potential partner and use his spare gas source or spare vice head.

4. Breathe directly with a large number of leaking regulators:

(1) Hold the regulator, press the mouthpiece outside your lips, or insert a small horn mouthpiece into your mouth.

(2) Breathe air, like drinking water from a water dispenser, and let the excess air overflow.

(3) Remember, don't seal the whole regulator with your mouth, just use a small mouth to inhale the needed air and let the excess air overflow.

(4) Keep breathing normally and don't hold your breath.

When you can't stop the regulator from leaking a lot, you should immediately rise safely and prepare to return to the surface. A lot of air leaks are very easy to escape, so don't try to repair them underwater!
