My brain died when I posted the 1st reply:
- obviously I meant "OPV" rather than "auto-purge" (but then I am getting on a bit)
- I think to adjust the OPV on the Sub you'd either need to be triple-jointed or a gorilla (or both)
I believe (under certain conditions) there were some problems with the exhale lung failing to re-fill after someone took a huge breath - this was fixed by shoving a curly-wurly in the lung!
