Why Regulators Freeze and Not Only In Cold Water

Needless to say, on cold water dives there’s a chance your regulator might freeze, but not for the reasons you’d expect.

Clue: it’s got nothing to do with water temperatures.

As an expert over at ScubaLab clearly explains, regulators don’t freeze only in freezing water. In fact, their research has demonstrated that regs can fail in waters as warm as 50°F (10°C). Why?  Well, put quite simply, it’s because of the drop in pressure from the tank to the 1st stage that automatically causes the temperature to fall.

This happens on every dive, but on cold water dives, the water can’t heat the reg as fast as it’s being chilled. Consequently, this can cause your regulator to fail and cause to much-dreaded free-flow effect.

Below are some useful tips form ScubaDiving.com on how to prevent regulators from freezing up:

  • Avoid breathing from the 2nd stage out of the water.
  • Slowly inflate your BCD, and never free flow your 2nd stage to fill an SMB.
  • Breathe slowly and steadily. Avoid any hard work.
  • Use a reg with an in-line shut off valve to stop free-flows.
