Long story how I got into this.
It started with my health and needing to reduce sugar intake. I stopped drinking all sugared drinks including fruit juices. In doing so, I developed a taste for drinking just plain soda water. My wife developed the taste for it as well.
I live in San Angelo, Tx and the city water quality here just plain sucks. I have well water but have to have a softener on it that adds sodium. I don't want the sodium and don't want to drink reverse osmosis filtered water either so we've been drinking Ozarka Spring water we get at Sams ever since we moved here. The 2 1/2 gallon jugs are as large as we can get here. Can't get the 5 gallon jugs delivered.
Anyway, last year I bought a CO2 bottle and started making the soda water in 2 liter bottles with the shaking method. I'm very tired of doing that and my wife wouldn't help. She would drink what I made and leave the bottle empty.
So, that led me to research a way to construct an automatic dispenser. I really couldn't find anyone that had ever designed anything that met everything I wanted out of a system. So, I designed my own. I'm thinking that I may be the only one that has done a system like this. At least, there's nothing like this I could find on the Internet. I thought this forum would really be a good place to share what I did. It just seems there would be people out there that would want a system like this.
I got it going yesterday. It is working fantastic. I started out buying a scratch and dent (but new) refrigerator/freezer and put it in the garage. I bought a McCann carbonator and separated the motor and tank from the assembly and put the tank in the fridge and the motor behind the wall (directly behind the fridge that is under a stairwell).
On the carbonator stand where the tank was mounted, I mounted a ShurFlo pressure pump that pressurizes a small bladder type pressure tank that sits in the fridge. The pressure pump sucks the water out of a 6 gallon tank that sits at the very bottom of the fridge. This pressure tank also connects to the inlet side of the carbonator at the motor.
In the fridge, I can store up to six 2 1/2 gallon bottles of the Ozarka spring water and fill the 6 gallon tank as needed. My wife is liking the idea of the extra freezer space with this too. Plus there will be a little room on the door shelves for some other things.
I mounted a soda dispenser through the side of the fridge that's close to the door from the garage to the house.
