My last Peacock dive brought (yet) another dry suit leak, this time around the inflator valve. Figured out later out the Schrader valve was loose and unscrewed from the valve body. I don't how it happened and why it was not bubbling with air. Anyhow, that got me thinking about other potential dry suit failures and how to address them during the dive.

I dive trilam suits with silicone seals. If any of my seals failed, the rings would keep the sleeve or neck opening pretty wide open. I guess I could squeeze a sleeve somehow to minimize the leak on the way out but the neck would stay open and collect more water with any forward motion. Being on the scooter would make it much worse. And trilam has no inherent insulation or buoyancy.

My questions: has anybody experienced a catastrophic dry suit failure during the dive (something like a ripped neck seal or the likes)? If so, how difficult was it to manage? I would appreciate hypothetical scenarios as well, but mainly would like to hear from people who actually went through it, with tips and ideas how to manage.

Thanks!
