That will take another two minutes or so... I have an inline valve (positioned after the KISS valve) It works immediately. (part numbers are in steevke's blog) For those that will argue that's yet another failure point... sure but I'm no alpinist. For those that think it's an additional risk. When it closes you can't press the KISS valve button. You'll know the very first time you try to manually add oxygen.
Can't find the blog, interesting idea, do you have a link to find the part number?
Thanks,
Neil
