Who the heck built it? The husband? Jesus. This is a story for sure. Is anyone investigating this?

The only possible answer is she did not build it. You can breathe from it - no problem. You just made a balloon. The valves facing each other essentially create a rubber stopper in the loop. You have access to the gas in the loop, bucket and CL but in a linear fashion.
Welcome to the thread.
Why the hell would Hollis put two mushroom valves on one side. I will be thinking of this for days...

What? If you breath out it goes somewhere in a counterlung and then into a scrubber. If the mushroom valves were both installed in same direction the air was going through the scrubber.
What you are suggesting is that one or both mushroom valves were not installed at all. Do you have that knowledge?
I dive a rebreather and understand the gas flow of a standard rebreather. Breathing in and out of a balloon suggests that either the mushroom valves were not installed, or the scrubber wasn't installed... Otherwise the scrubber is in play. If both mashroom valves are oriented in opposite directions you either can't breath in or you cant breathe out.
If an o ring was omitted fine then yes the scrubber may be bypassed but if the direction of flow is switched there is no reason why the scrubber wouldn't work...

Did you not read my BOv comment. Are you denying that people have actually bailout out and survived a CO2 hit?
It's possible although not ideal to have a CO2 hit at all obviously.
A lot of these comments seem like they are coming from people who don't dive rebreathers... Just sayin.

You have a lot of Rebreathers listed in your profile but do you actually dive Rebreathers frequently or are you teaching often?
I'm not convinced this was a primary CO2 hit as opposed to a flooded rebreather event with building CO2.
Everyone has an opinion. No one has to like mine...
Breathing in a balloon... Not good for your health...

Glad you got it, because I was about to post saying "read the whole F'ing thread", because it sure looks like you hadn't.....
3 minutes into the dive and their was something fundamentally wrong with that scrubber or assembly (like missing O-rings). Breakthrough or bypass that rapid should have been detected on pre-breath even.

All the checklists I have seen are stupid long with superfluous lawyer written stuff in like there like "fill O2" and "check for damage"
This creates lengthy checklists which then get ignored or not used. To avoid this I made my own. No its not manufacturer approved but making the checklist actually useable and legible is key to actually using it every time, which is how you stay alive. Manufacturers need to learn 1) how to design out potential assembly/diver errors - e.g all Orings should be contrasting colors so you can immediately see if they are missing or cut. 2) how to write briefly and concisely.
Just last year weren't you lamenting how your scooter couldn't be trimmed in freshwater? Having an un-trimmable scooter released for consumers is an indication of the thoughtfulness of those engineers and honestly I think its an enormous oversight. I wouldn't be surprised if some CCRs have the same types of issues, for instance I have heard that one CCR has 1 absolutely critical oring and a dog hair in it can lead to CO2 bypass. That's the kind of single point failure that needs to be designed out or at least made very difficult to create.
