The first task in setting up my soda fountain was to upgrade the RO. My old one was pathetic, and drove me nuts anyhow. It was some GE thing, that generated like 3 GPH. The new one is from bulk reef supply. 75 GPH, and I added a pressure pump to it to make sure it kept the tank full. I also went ahead and replaced all the lines with 3/8" instead of the 1/4", because the carbonator needs a lot of water, and apparently a 1/4" tube will not cut it.
The first picture here, is the new RO, all installed (except for the final plumbing to the carbonator). I added a bunch of valves to the installation, so I could easily shut off sections of it for replacement in the future. In the past I've had to drain the entire system, shut water off, etc to do any sort of work on it. This should fix that silliness.
Another view showing the new bits in place under the sink. Yay.
Here is a "before" shot of the kitchen, all primed and ready for a bunch of holes to be cut in it! The tower will sit to the left of the fridge, next to the sink. The carbonator and chiller will hopefully be going in the cabinet above the fridge, and the CO2 and bag-in-box syrup will live in the pantry next to the fridge.
