Assembling Your Scuba Gear
Testing the Scuba Unit
- Make sure the valve knob is opened.
- Listen carefully for air leaks near the valve or 1st stage. A hissing sound usually indicates a worn or cracked valve o-ring, which should be replaced before diving.
- Check the submersible pressure gauge to ensure the cylinder is full.
- While looking at the submersible pressure gauge, breathe from your 2nd stage and octopus. If the gauge's needle shifts, the valve is closed or there is an air restriction.
- Check the air for oily taste or odor. If you suspect the air is contaminated, do not use the cylinder. Return it to the shop that filled the cylinder so they can test their compressor.
- Test the power inflator to make sure it inflates and deflates.
- Over-inflate the BCD to ensure the over-pressure relief valves vent the excess pressure.
