BCD Bladder Failing
« on: 03 Jul 16, 01:45 »
Just out of curiosity, has anyone here ever experienced complete failure of the BCD bladder before? What was the cause and how was the repairs done? To date, have never heard of such a critical failure before. Inflator malfunction yes, but bladder failing... never.

My old Halcyon bladder developed a leak somewhere.... and while it will still hold air.... eventually the air will start to leak within an hour or so... sadly, I wasn't able to find and plug the leak... and give the bladder away to a fellow diver who last I heard, found someone to repair the bladder...

dump valve failures are common. either the spring corrodes and rusts away, or the whole dump valve separates from the BCD. Have experienced or seen these a few times.

also elbow joint failures where the whole thing separates from the BCD, or cracked joints.

plus all the usual inflator problems.

Its actually possible.  Imagine pulling dump valve and it detaches from bladder.. damn.. scary thoughts!  :P

Just make sure our equipment is serviceable condition and also do not overweight yourself!
So they call it a 'FACT' coz someone made some statements on a 'FACT SHEET'? hummm...

I had a corrugated tube (inflator, near the elbow) broke while jumping into water. Only notice when underwater but completed an hour of dive time as a sinking diver.

If that happen, just pass extra weight to the DM to carry. What about blow a bit of air into the SMB and tie the smb to your BC? :P

diving with a lift bag is better for bc failure, as lift bag, those with dump valve you can control the amount of air and lift needed thus acting as a external bc

Thanks for sharing your various experiences. Only hloc has a bladder leak, rest sounds like the failure point tends to be at the elbow and dump valve. Reason I ask is... my BCD hasn't been used nor checked out in a few years. wondering if its time to send for some attention.

Usually what i do when my equipment don't touch water for a while, every 3 month, i will soak in in a tub of water for 2 days and dry them before storing again, so that the rubber part comes in contact with water to prevent them from getting too dry. did the same for both my reg and bc. "not sure if its the right thing to do" but so far its quite alright. haha
