Flooded Scrubber

**Steve** · 24th April 2007, 02:24

Mike has a thread running about flooding and then restarting scrubbers and it got me wondering; how often has this occurred to people? I have been diving CCRs for almost 15 years and I have not had a loop flood. Sure the odd cup full of water but never a flood. How common is this happening?

I have flooded my CCR-Dolphin a couple of times. Once on the surface and once during a dive.

However I must confess that both times could have easily been prevented by paying more attention to bubble checks and negative pressure test...

That depends on your definition of a flood. I've managed to fill a lung once or twice but been lucky enough not to sponge the sorb.
I'll vote as such.
I would expect that the majority would vote in a similar fashion but this would be mostly due to the design of some rebreathers with water traps or OTS lungs. Those with neither would carry more risk.

Twice in 18 years and both times hurt......a lot.

No time for pride when your throat and mouth are on fire.......

Cheers,

i've not flooded my unit (and voted as such), but the previous owner had! something about a pod coming off???? MHD has flooded his aziCCR (thread is on here) and another SK diver from D3 flooded his without a cause ever being determined.

In a couple of years of Rebreather diving I floaded my loop only one time, at surface cause I had dropped the mouth piece.
Apart from that I saw one cannister floading in my group , the dolphin breathing bag had not been properly "clicked" to the canister and went out causing a big dil leak and after a canniser floading.
the rebreather had sucessfully passed the pressure test because the port was intaken far enough to be on the cannister o ring, but not deeply enough to click and secure the p-port on the cannister
In my opinion it is important before to get down deep to stay a good couple of minutes at the anchor line around 6 meter to check, bubble check and see if everything is okay...

It's only happened once (so far).

When we were using the original Jetsam displays, which had the leads running through a length of tubing to keep the displays at ambient pressure, one of these tubes had developed a crack (I'd used it for years, and it was used when I got it). All positive and negative checks passed pre-dive, but once I was wearing the displays, the lead and tube were pulled far enough to open the crack.

This resulted in a slow flood, which I didn't notice until several minutes into the second dive of the day.

Until we changed to the Sub Sea Systems displays, I made it a point to wiggle the display leads while doing pre-dive checks after that.

cheers...

I flooded my KISS on my third dive ever with it, which is a testament to slow progression (planning a 3.5hr dive to 60m'ish in retrospect wasn't a good idea on the first cave dive with the unit

).

Bailed off the loop in the deep section of the cave after the WOB became unpleasant. Once I got shallower I went back on the loop and managed to complete the full deco. The only problem was loss of loop volume so I ate through diluent and then O2 when I hit 6m.

Diving on homebuilds for a few years meant floods was a regular occurence, so I've had a lot but never a cocktail. I stupidly licked my finger after filling my scrubber once and puked solidly for 5min so I have a great deal of respect for anyone who got through a cocktail underwater.

Cheers,

Stuart
