Diagnosing common dive-equipment faults

Knowing the symptoms of equipment faults allows you to act before the problem turns into an emergency.

A leak in the regulator

A continuous air sound without breathing, or air leaking from somewhere. The solution: stop the dive and ascend.

The buoyancy vest does not work

You cannot inflate or dump air. Check it in the pool before going out to the sea.

The regulator delivers air with difficulty

It needs service. Do not complete the dive with a regulator that works with difficulty.

The small fault you ignore today may become a large crisis at the deepest moment.
