How many time did you flood your unit

[Attchoum]

Hi,

The question came up on a other forum in a discussion about flood recovery.

Did you ever flood your unit outside of tranning??

What happen???

Well, it became difficult to breathe, and the gurgling was somewhat of a hint. Just aborted the dive to find what went wrong. Found the DSV not in position all the way, and another time(s), I left the mouthpiece open whilst walking into the water.

The first test of my prototype sidemount scrubber, I left one of the latches open on the scrubber, yuck what a taste! Second time was my fully sidemount prototype. The connector for the ADV failed. The third time I was testing a sidemount prototype for someone else, and I dropped the rebreather. It seemed OK, but there was a crack in the scrubber, and it slowly filled with water. The 4th time was yet another sidemount prototype. I wasn't getting enough O2, so I bailed. I was so hypoxic that I failed to close the DSV.

I guess you see the common denominator, testing prototypes can be hazardous to your health :-D

I thought that the common denominator might have been YOU. :-)

So wrong........but funny!
Forrest, you've had as many floods as the number of Spinal Tap's drummers.

Good one :-)

So far, other than some minor gurgling from loose lips when task loaded, no issues. (Etienne, remember when Mel bit my finger during a dive to reinforce keeping a tight grip on the mouthpiece? I've still got the indentations!)

[Slüdge]

Loose lips sink rebreathers.

I had a dive partner kick a dsv out of my mouth once....It was on a night dive off the cost of Kuwait. I just cleard it and thru it back in. I think the moisture trap held most of the water. I have seen students flood at least two every class. Only have ever seen one real bad "caustic cocktail". I guess the gurgling and burning sensation where not enough for this kid. We had him on the boat puking for hours...found that coke helps better then water.

...found that coke helps better then water.

Interesting and makes sense. Presumably the acidic coke helps neutralize the caustic cocktail. (Or maybe it just substitutes a better taste!)

[netmage]

So it all started with this garage made scrubber and in hindsight makes perfect sense.... The little rubber feet on the bottom were just a little too big and led to latch stress, and me ultimately leaving the two internal (towards the backplate) latches removed, which led to a rather large gap, discovered immediately at depth..... This was an ocean dive, flushing dil I was able to stay on the loop and ascend. Putting the latches back on, had an o-ring roll a bit, still w/ those feet involved, caused a small gap again... Nothing catastrophic just downright annoying... Of course, the root cause was always pure stupidity, and I paid for them - a proper pos\neg would have revealed everything.

The only other flooding has been minor by comparison, mostly due to loose lips... Once @ Ginnie I had a loose DSV lever, which resulted in recurring gurgling in the mouthpiece, maybe 3-4 rolls during the dive before I realized where it was coming from... with OTS CLs, dump into the lung to resolve. A cup or so ended up in the bottom of the can.

I used to flood my unit on every dive, but got tired of all the shrinkage and bought a dry suit!:rollguy

1. Ripped loop hose on wreckage crawling into a tight space.
2. Mouthpiece on DSV turned 45 degrees without my knowing while crawling into a tight space.

I guess I've got my own common denominator.

[aainslie]

The basic piece is just bailing out. Dealing with the head games can be interesting, especially in caves.

My question was originated from a other forum. They where talking about how important is the option to de-water the loop. Out of the pool we have here,72% never flood there unit (and some of you flood it in really strange circumstance...) I would say that the option of de-water is nice but definitely not a most.

That pool bring me a other question that I did not expect. Is there really only 25 diver that use rebreather on that forum????

[adam0321]

I don't dive a breather in caves but for work. I am saving for a meg......

It's VERY nice. I've been very pleased to be able to recover the loop on deco after pretty big floods on a couple of occasions.

[adam0321]

does the meg have this option?

[swadiver]

400 plus hours on CCR, never flooded one. (so far)

[Randy Thornton]

One flood. Happened in Eagles Nest due to a split mouth piece. I was very grateful for a unit that was flood recoverable. I would be very hesitant to do any serious type cave dive in a CCR unit that was not flood tolerant.

[scubadam67]

funny Forrest all of mine have been on prototype units as well. mike tells a great story of my first caustic cocktail where he found me walking the shore pucking. he asked me why i was walking around and i told him i was looking for a dog so i could its butt and get this taste out of my mouth.

[rchrds]

Flooded only once that was my fault completely- I was new to my machine, and had not developed the muscle memory for changing my BOV to OC before taking it out of my mouth- pretty much complete flood. Good thing, I was only prebreathing at the surface prior to a dive- swapped scrubber cannisters (I have several) shook out the water, and made the dive. Other times, my breathers have old OPV valves- replacements are no longer available, so they tend to weep a bit of water. The worst ones, right before they get thrown out barely hold a negative pressure test, or not for very long. These tend to let water into the counterlung, and over a 4 hour dive there will be a significant amount of water in the counterlung. Not a full flood, as long as I stay horizontal, it doesn't hit the scrubber, but if I go vertical for some reason, the slime/water can hit the lowest part of the scubber bed and start channeling.

Operator error putting bottom of scrubber together... not a huge deal and really obvious!

[adam0321]

I wish I had one of my own to flood. I have finaly got it between two models. And the Marine Corps jusr brought back our re-up bonus:) so I just might be on the loop before to long.
