DIY $1 SodaStream Cylinder Refills 

I now use this CO2 Wrench: amzn.to/3Yg9LPo It's $9 and works way better than the pliers to quickly tighten your adapter hose to the main tank.

Out of dozens of videos on this in YT, this is by far easiest to understand. Great job!

I would still replace the small cylinders every few years, though. A gas cylinder needs to be tested periodically for safety, which is why the big one will have a date stamped in it. The small ones won't be getting that periodic safety testing at home.

I've watched at least a handful of these already and found myself confused every time, this was easily the best one. thanks for answering all the questions and troubleshooting.

THANK YOU IVE been searching and getting close however THIS video was CLEAR INSTRUCTIONS

Best how to vidio I've seen BTW. Great job!!

Nicely presented video! I've just begun researching soda makers so I appreciate all the detail you've went into with the whole process and the equipment you used. Small nitpick with the use of locking pliers since it's not the best tool for tightening the valve vs a wrench.

I believe that you can get a hose adapter straight from the 20 pounder to your soda stream, you need a tank without siphon, tho.

Know that your tank is a pressure vessel and has a service life - it is etched into the tank. So, factor into the cost of your shiny new tank - it will be useful for several years and then you have to replace it or have it tested...this is why going the exchange route can be less expensive. You still pay for a tank, and the tank will probably not be pristine, but you can exchange tanks with your gas provider FOREVER.

Is there an adapter for the newer quick connect soda stream canisters that can be used to do this?

I have the same Aarke and refill equipment as you except I have a Kegco 5# tank that I had a siphon tube installed within. Yesterday, I took the tank in for a refill at a local fire extinguisher company. Their CO2 is food grade (I asked them). It cost $17.20 for 5# of CO2 ($16.00 + $1.20 tax). It costs me around $2-$2.50 per refill. More expensive, but the 5# tank is much easier to handle. Ideally, I would have purchased a 10# tank. Nice balance between refill expense and handling, IMO. That handle is not to protect the valve. It's a carrying handle only. Lots of internet reviews complaining about broken handles. You also don't want SodaStream canisters as they have a valve designed to prevent refilling by the user. Other brands have a valve with a small pin instead of the SodaStream flat disc in the center of the valve. The other brands fill easier and faster. THANKS for this video!!

I have the same setup, and have not been able to refill more than 50g (due to lack of freezer space, I'm not freezing empty tanks). I was getting 200g when the tank did not have a siphon tube and I had to invert it. I'm hinking really hard about removing the siphon tube on the next refill. I'm also beginning to think that carbonating directly from a regulated non-siphon 20lb tank to water bottles may yield hundreds more liters of carbonated water. Experience and some research tells me that siphoning liquid Co2 may be extremely inefficient.

Good video but it would be more logical to set the zero/tare on the kitchen scale after you have placed the empty sodastream cylinder and filling valve apparatus on the scales. That way you are only measuring the weight of the Co2 as it transfers into the empty sodastream cylinder and there is no need to do any approximations or addition calculations to arrive at the correct filling weight.

How long can you keep a full co2 cylinder ? Say if I have a 20 lb cylinder and with 5lbs left after year or so is that still good to make sodas?

Will the adapter work for a Ninja Thirsty? Seems like it might since Sodastream canisters work in Ninja port.

I got an adapter that goes straight from the big tank to the soda stream.

Will this setup work with the Aarke Carbonator III? Thanks

@0:54 "if you do experience dizzyness or confusion..." what? Run for US president?

I used to use the direct adapter and had to invert the cylinder. Could never get the original sodastream cylinders to work. And when still 3 of 10kg were left I only got about 100g in each fill, even frozen. So in the end it was not worth the hassle for me and I went back to swapping cylinders at the store.
