Air Supply to BC Disconnect?

[ronski101]

I was recently on a dive where I had to get geared up fast and into the water due to rough seas and current. The captain brought me my rig while I tried to stay balanced on the back of the boat while holding my mid sized camera/flash. During the rush I inadvertently put my arm between the air supply line from the tank to the BC and the BC control hose but did not discover it until I was already in the water and tried to go down. Fortunately I was able to pull my arm out without disconnecting the pressurized supply line. My question is, could I have successfully disconnected the supply line and reattached it without losing air or water entering the BC after removing my arm?

Not 100% sure what you're asking but, you should be able to connect and disconnect the low pressure inflator hose from the inflator underwater while pressurized. There will be no intrusion into the hose and very little water through the inflator connector. Should have been done during you're open water course. Does that make sense?

Yes, you can do that; but it can be difficult. It is a useful skill and should be practiced until you are comfortable with it. And then practiced occasionally thereafter.

Being able to disconnect the BC inflator hose is an essential skill that you need to be good at. Someday you'll have a BC inflator valve get stuck on, and you need to quickly disconnect the LP hose to avoid an unintended ascent to the surface.

It is reasonably easy with bare hands and gets harder as glove thickness increases. Quick disconnects with larger flanges can be helpful:

I didn't get a very definitive answer here. I know that I can disconnect the pressure hose to the BC underwater but I don't know if I can reattach it and while tryng to do so will water enter the BC or will air come out of the BC? when I got certified, we didn't have BC's.......

Yes... no problem. Just do it quick and solid, and you will not get noticeable water in/air out...
And if you did, it's absolutely no problem... just rinse the inflator good after dive. (Witch you should do anyway)

You not.only can disconnect and reconnect you need to be able to. You should have had to do this in you OW class.

Don't worry about the small amount of water in your bc, you will usually have some after every dive anyways.
