I have a couple of 20 pound co2 tanks that I use to refill my sodastream cylinders, ends up being less than a dollar a fill.
I have kegs, but it feels like such a pain in the ass to carb water. The pressures required would mean I have to change to much longer hoses than I use with beer.
How do you fill the small canisters from the big ones? I have a 20lb CO2 at work I can pull off of. Do you need an attachment?
You can buy the hose on Amazon, lots of options.
Unless your donor tank is a siphon tank (unlikely), you'll need to turn your donor upside down to push liquid instead of gas.
To get a pressure differential, throw the soda steam cylinder in the freezer for a while.
You have to fill slowly since the soda steam cylinder has an anti fill valve. But it won't trigger if you fill really slow.
I pull the cylinder from the freezer, hook it all up and put it on a scale and transfer up to 410 grams, but this method is likely to equalize pressure at 350 or so.
You could just use it as is mostly full, or if you want it totally full throw it back in the freezer for a while and redo the transfer process, or close your donor tank and vent some gas quickly from the soda stream tank in order to cause a rapid pressure drop, then that will allow a little more to transfer.
I never worry about getting them all the way to 410 grams, since it's so easy/convenient to just fill them 80% full.
