  If you experience reduced airflow or significant breathing resistance with your Aqua Lung Diving Instrument, first ensure the cylinder valve is fully open and check the cylinder pressure. If the issue persists, try using another cylinder, as the valve may require servicing. A blocked filter could also be the culprit, so replace the filter. Finally, ensure that the cylinder is not empty and charge it if necessary.

  An increase in MP, which may cause a second stage leak in your Aqua Lung Diving Instrument, can be due to several reasons. The HP seat may be worn or damaged, requiring replacement. The crown could also be damaged and need replacing. Additionally, check if O-rings are worn or damaged and replace them if necessary. Damaged O-ring grooves on the plug or crown may also cause this issue, necessitating replacement of the plug or body. Finally, a worn or damaged diaphragm can also lead to an increase in MP, requiring its replacement.
