Growler Upgrade - adding carb cap for counterfilling/extra carbing

[claypot]

Sweet mate, I'll pick up a growler and get onto it.
I got a couple of stainless Schrader valves that are like a bulk head fitting and will try to fit to the original cap.

Jeez guys you are making a mountain out of a mole hill
I have the cheap growlers from ebay$17 ea delivered & use a drafto on them. The locking arms on the drafto need to be bent down to allow the drafto to be used on these growlers as the swing fitting is a little different
Fit airline push connectors and a tap $3-4 to the gas side of the drafto & you can then use co2 to pressurise the growler
Keg king have an adapter to use a soda stream bottle to the regulator
There is also a single shot thingio on eBay for adding co2 to pressurise the growler on demand so no regulator required and no wastage of the gas

That Kilkenny looks pretty flat you should work out a way to get more co2 in it
I'm more about putting the beer in the Vac growler and giving it a blast of Co2 then on me way. Tip the beer in a glass when I get there. Too much crap hanging off 2 litres for me.

Yes the brew in the glass was a bit flat. It was only my second pour from the growler set up and my only pic of the entire thing
I’ve worked out to set the gas at 15 psi so I get a good head, and can also force carb the beer at that so I now stick to setting the gas at 15 psi
Works for me

Could something like my attached pic work? Essentially you keep the carbonation cap you already have, put a rubber washer under and make a new clamp to hold it down.

if you read the thread and see the final design - there's just a schrader valve hanging off the unit - real simple and elegant. no C02, no reg, no tap. Just buy install a hex bolt and a valve on the drafto, with the complimentary fitting to your home C02 supply and you're done. So, take it easy with all that kit hanging off your growler.
