This is great advice but doesn’t get around that fact that sodatreams themselves are cheap plastic, have weak valves and don’t last super long. I have seen all-metal carbonators for sale online but they’re $$$ and I’m also not sure how easy they are to convert to a larger tank.
This is definitely not “BIFL” advice but sodastreams are cheap and usually there’s one or two at thrift stores so it’s not the end of the world if one breaks.


































Is there a step by step tutorial for this you know of?
