I’m sick and tired of paying soda stream. Mostly on principle. My wife really likes her carbonated water though. So much so she’s green lit a kegerator for the sole purpose of housing a 5 gallon corny keg of carbonated water! Carbonated water on tap. Even better, I can plumb it into the fresh water line so it’s continuous! Infinite soda water on tap… till the co2 tank runs out anyway.
I’m sure this is all old school to any home brewers. But it’s all new to me. Now to build it all…
In commie times or early 90s in eastern Europe people (or at least my friend) used to have at home extremely simple device soda charger adapter with two PET bottle connectors on top and bottom, where on each end you could screw 1.5-2L PET bottle, I think one filled with syrup water, other empty, in the middle on side you screw small soda charger bomb (see link, think size you could put in small air gun, one small bomb cost around 13 cents nowadays, reasonable even for one time use 2L) and then you just release valve and I think you had to flip over bottles few times. It was incredibly simple and I'm amazed by pricey SodaStream popularity (even over soda siphon/seltzer bottle). Shame I can't find this adapter on mobile, so now think it had to be home made device which was very compact, no pipes required, everything within small adapter which fit between two bottles with bomb on side.
Go for it! I experimented with adding cheap drink powders like lemonade and coconut to mine and loved it! Make sure the system and connections can handle the pressure you're setting!
Refills of CO2 can be had at any local home brew supply shop, some local breweries, airgas, etc.
The corny keg I'll just fill with filtered tap water. It can be made continuous with one of these, but I'm not sure I have the water pressure for this:
