It's not related to temperature. When lowered a few cm into water with the
mouthpiece up, the 2nd stage when properly adjusted would release air. It's
not a freezeup since it's stops when flipped over. Go to your diveship,
they'll adjust it. You could give it a go yourself, but since you pose the
question I figure the safest approach is the diveshop...

  I have a Mares MR 12 with a Mares Arkos second stage and a sherwood octo.
The last 2 dives I cave done I have had very slight free flows. The first
time I was in 32 F degree and the free flow was somewhat noticeable and got
worse as the dive progressed. I aborted the dive once I noticed it becomming
a problem. I have a cold water kit on the first stage however I chalked it
up to the extreme temperature. My father used it next on a pool dive for his
certification and he didn't notice any problems with it. The next dive was
to 40' in 39-41 F dergrees water. near the end of the dive about 15-20 mins
into the dive I noticed a positive pressure in my mouth. Not a major free
flow but enough that I could feel gas wanting to just push my lips out a
little. I switched to my octo wich was breathing good and I noticed that my
reg would flow as it should when it was turned upside down and when I turned
it right side up it would still be releasing a few tinny bubbles. Any
thoughts as to what might be the problem. Would the water temp on the second
dive be cold enough to cause a freeze up?

  Thanks,
  Thom
