How to Do Visual Check of SCUBA Tank

The air tank is a key part of a diver's gear bag. A thorough visual inspection of the tank will ensure the safety and longevity of the unit, the dive and you. Usually, this inspection is done by a dive shop, but it should also be done by you and your dive buddy before you hit the water.

      Stand the tank upright before securing it to your BCD, or bouyancy compensator. Check the overall condition of the tank, looking for any dents or deep scratches that may compromise its integrity. Check the label to see when the tank last received hydrostatic testing to ensure the inspection is current. Few reputable shops will refill a tank that has expired.

      Use your light, if necessary, to inspect the valve's O-ring. Regardless of type, this small, rubber ring allows for a tight seal between the tank and air hose(s). If one is not present or it is damaged, replace immediately. All components should turn easily, regardless of your valve type (J, K, DIN, etc.).

      Check the boot (the plastic or rubber base of the tank) for any signs of corrosion. If any is present, postpone the dive or use another tank. Ensure the tank fits into the BCD's pocket and firmly attach all straps.

      Pick up your BCD with the tank attached to make sure the tank stays in the pocket.
