I was recently given a Scubapro mk2 because the owner wasn't using it and the yoke retainer leaks a steady stream of small bubbles.
The pressure on the LP ports is stable and it breaths well (in a shop lab and a pool), but somewhere between the the yoke retainer, the o-ring inside of it and the yoke body, something seems to not be sealing.
Could it simply be that the o-ring needs to be replaced? If so, could somebody perhaps give me a pointer to something which lists the size of the o-ring?
What other directions could I look in for the root of the problem?
