There are always potential risks in everything you do. The below safety guidelines come from Beverage Factory.
1. What you’ll need to buy
Links above are just examples to illustrate the parts you will need. Shop around at local businesses, order from wherever you want.
Use the chart below to figure out what works best for your space. Yield estimates are conservative. I use a 5lb tank at home and replace my tank every few months.
Cost to refill/swap and empty CO2 tank
This is going to vary greatly based on your location, the size of your tank, and the shop you go to. A welding shop might refill your 5lb tank for $10 where a homebrew shop might charge $28 to swap your empty tank for a full one. There’s no point in paying for a new shiny tank, just get the cheapest one you can get from a reputable source.
Co2 Wrench (Optional But recommended)
2. Assemble your tank
You’re almost ready to make some soda.
If you are completely unfamiliar with how a system like this works, you should probably read section 3, but don't allow it to discourage you from buying a CO2 tank. It takes less than a minute to check. It is just an added precaution to make sure your CO2 tank is set up correctly.
3. Check for Leaks
There are 3 areas where your setup can leak CO2.
To test the inlet located at the 3 o'clock position on the regulator:
If you have confirmed there are no leaks in your regulator to CO2 tank attachment it is time to check the 2 connections on the hose.
You’re now leak free and ready to make some carbonated beverages
Make some soda or carbonated cocktails
