SO if a vent is designed to let air in and out allowing for contraction and expansion does that mean when it is under water it will suck water in as the board cools. I have seen my bubble around the sides while I paddle along in the sun and the board heats up, so would it be obvious that when the board cools and the vent has water around it suck water in as well ?
if is a gortex type it's only suppose to breath out. a lot of the valves have a small wells in them so the gortex is up the top and not in water all the time. this water in the well should be whats bubbling then the board heats up. if you have small leaks, it will also come back out then the board is hot as well as through the vent.
the only problem with a one way valve breathing out is if the temperature inside the board get really cold the board can't take in any air
