Well just to let you divers know,had a burst disk blow a few years back prior to a dive on dry ground with a supposed to be rebuilt vale that was not!
Now Yesterday as I was unhooking my video cam rig from 20' safety stop link on my anchor line -this was a solo dive and I had a back up pony live with its 2nd stage under my chin on a necklace,
The day started out high 80's and my tanks were kept in a cool place prior to dive,on searching 2 hrs "Mowing the lawn" on some poor/bad GPS no#s by a famous local wreck authority I decided to drop a marker on his no#s and lay out several hundred feet of scope and do a wreck reel grid search off the anchor just to see if a thermo Cline or silt may have obscured this wreck in the Bay of Green Bay Wisc,
I geared up let my video cam down my anchor line to the safety stop,sprayed my reg and hoses with a mild mix of Ivory soap used to lube my wrist seals on my dry suit and after a quick check =no leaks next to my dry bleed on the Sherwood reg I hit the water.
At about 18'FSW I was unclasping the video rig and checking things over for My decent to the bottom at 105'FSW when I had a push or force between my shoulder blades and heard the sickening sound of bubbles ! I quickly grabbed my main spg on my 130cuft HP tank and found the pressure at about 3400PSI and felt the loss was due to the cool down on the tank upon entry and it seemed to be holding,then I grabbed for my pony SPG on a 30AL cu-ft and found it read 3000 as it should and all the time I am saying Din-Din I should convert all to din thinking I had blown a yoke o-ring,I re hooked my video rig and watched as it slide down the line to the bottom as I had descended below my safety link,I added air to my wing and clipped my anchor tie off line=like a john line used to (safety tie off into a wreck) to a d-ring and anchor line as I as scened to the surface thinking if the leak or something blew or ruptured I would of rocketed to the bottom or off the anchor line !
Top side as I hit the surface I could feel the water and air splashing on my back and a look at my main SPG had me at less than 3000PSI I then switched to my pony reg for the quick swim along my tag line to the ladder,on the boat I took my rig off and found this see the photos,
1. Tanks were not in any way over heated,
2. tank was only 6 months new
3. took tank to a LDS for a vis and new oring and he had not seen this on a newer tank, and did not have a explanation next to the o-ring he replaced it with seemed less dense,or tank valve was not tightened properly at initial vis /valve installation
That said wow any thing can go wrong and to have back up air or a source of redundancy is a must have solo or buddy same lake /ocean diving!
By the way the tank leaked for about 40 mins till it ran down.
Dive safe,
Brad
Look at that o-ring ! so even your din valve tanks can go Opp's
