When a first stage feeezes and causes free flow in the second stage, will it also overwhelm the BC valve and/or the drysuit valve? I've never heard of this happening, but a discussion with my local dive shop left me thinking it might.

The second stage is designed as a fail-safe valve. That is, when there is a failure (such as a frozen first stage), it fails open - resulting in a free flow. The BC and drysuit valves are not of the same design, so the same results do not occur (a good thing as those would not be good results with those valves).When a first stage feeezes and causes free flow in the second stage, will it also overwhelm the BC valve and/or the drysuit valve?
