I actually ended up hooking a venting line onto the blowtie and taking advantage of the vented CO2 by using it to dispense a keg full of starsan into another keg, leaving me with a fully O2 purged keg. Saved me wasting the bottle gas.
Nice idea - I'll steal that! Still using the spring poppet type not the blowtie, but will try one at some stage.
My only gripe is with the Kegland video.
It's 7 1/2 minutes showing why the spring poppet type is bad and about 15 seconds saying why diaphragm is better, but not explaining exactly how it works.
Obviously a marketing video not a truly informative one.
Just to clarify - not knocking the product, just the video.
I'm not on the blue or red team, I buy from whoever supplies good product at good prices.
