over pressure valve
The snorkel valve is to breathe through on the surface, as the plans
indicate. It would also serve to equalize the cabin's internal pressure on the
surface.
Hi Chs Hugh
Can you or anyone else please tell me if the
snorkel valve is necessary and is its purpose also to equalize the subs
pressure on surfacing to open the hatch.
Thanks

Question,
Does it work? Is this an idea or a proven valve? What stops the
O’ring from falling out and jamming the valve open?
Chs,
