I would be interested to hear if other people have experienced the same problem with OPVs. Is this issue native to Optima valves or have other cave divers experienced this with other brands of OPV?
Actually, I did not provide complete information in my answer. So, I may have created a misimpression.
The issue with the OPV was actually with my drysuit OPV, not my Optima OPV. I was just extrapolating this to answer the question about how something like this could happen to an OPV at all.
