I found it cheaper and much, much more convenient to get an adapter to refill the countertop carbonator's CO2 cylinders from a standard 20 lb CO2 cylendar. That way, you can carbonate from the much smaller and easier to use countertop unit, you can service multiple countertop carbonators from a single larger tank, and you can leave the larger tank shut off and away from living areas so that a leak doesn't pose a hazard.

> I found it cheaper and much, much more convenient Cheaper? I don't see how. We're filling from the same CO2 cylinders, and my total hardware cost was less than that of a midrange SodaStream without the adapter you describe. More convenient? Maybe, depending on environment and use. But mine has advantages, too: More fizz, no counter space required, fewer fragile plastic parts, standard components that are easily serviced/replaced, and the ability to carbonate liquids other than water without worry of backspray gumming up a countertop machine's internal components. (Your unit's instructions probably tell you to use only water, for this reason.) > you can leave the larger tank shut off and away from living areas so that a leak doesn't pose a hazard. I close my cylinder's main valve when it's not in use, and the two additional valves downstream of it (at the regulator and ball lock fitting) also work, so I think a leak is very unlikely. Even if there was one, I would expect it to be noticed quickly or else too slow for the released CO2 to cause harm.

  SodaStream carbonators are super common at all the thrift stores near me, so they're like $5 to $10. There's one on eBay right now for $25 with free shipping. The refill adapter was $10 on AliExpress, but the cheapest regulator alone cost more than my entire setup.

  One advantage of standard tabletop carbonators is that you can get versions with glass bottles. I quite like the 0.7l glass sodastream bottles. You could probably get them to work on a DIY setup with the right pressure regulator settings and the right adapter. But I'd like to avoid the flying glass shards if I get it wrong

    Do you mind my asking which ones you use? The only ones I've been able to find (Canada) don't work with the standard soda stream

      I use SodaStream Crystal. There is the older Crystal 2.0 that uses the old generic screw-type CO2 cylinders, and the newer Crystal 3.0 which uses the patented quick-connect cylinders. Looking at the Canadian website, neither is sold in Canada (1 for a link on the German website). There is the SodaStream Duo which supports a different type of glas bottle. Might be easier to source locally, but exists only with the quick-connect cylinders and is a bit expensive for what it is, at least if you buy it new [1]: https://sodastream.de/products/crystal-3-0?variant=40465483268175 https://sodastream.de/products/crystal-3-0?variant=404654832...

        How's the durability of the Crystal? I had two of the original Penguin systems, and the seals broke down and the frame stretched. I'd prefer to go back to the glass bottles.

        No issues with the Crystal so far. It's pretty sturdy. But that's the old 2.0 model, looking at the reviews the new 3.0 is a downgrade in terms of quality, in addition to the downgrade of being forced into the proprietary cylinders

        Bummer. I loved the glass bottles in the penguin, but I got tired fighting the durability problems. I got as far as researching custom gaskets and shims, and gave up.

Before the plague shut down the place I got my larger bottle refilled, I got a mid-size standard CO2 to SodaStream adapter from Ali Express. Saved me a fortune hooked up direct to the SodaStream, especially as sparkling water was intermittently surprisingly difficult to get hold of during those times. I should contact the gas supplier, see where the nearest point is now.
