I love it, and for anyone else who does, I have a suggestion.
Get a SodaStream (or whatever your carbonator-of-choice is) and a cheap adapter to run it from a standard CO2 tank. Not only do you save money on CO2 refills, but you save money on buying cans of seltzer, too. The concentrated flavor additives are only a few dollars at the grocery store.
I think my SodaStream was something like $100. The adapter and hoses were $50-ish. The flavor syrup costs around $5 for enough to make gallons. Every few months or more, I might pay $50 or so to refill a 20lb CO2 tank. It’s already paid for itself, and it’s incredibly convenient.
You can skip the soda stream and use a cheap carbonator cap on standard plastic bottles and a ball lock connector on your gas line if you’re willing to shake the bottle manually.
I’ve taken this setup a couple levels up over the last 5 years.
First level: kegerator and switch out the bottle for a keg, bonus points for using a diffusion stone in the keg to speed the absorption of CO2.
Second level: plumb the water line and use a continuous carbonator lid on the keg. Your gas pressure will need to be 10-15 psi (.7-1 bar) lower than the water pressure. Even a small 2.5gal (9.5L) keg makes for nearly infinite cold fizzy water at reasonable consumption rates.
Happy to make a parts list if anyone is interested.
Soda stream is on the BDS list. Buy second hand at best.
