Build a continuous carbonated water dispensing system at home! Here’s the high-level process:

  1. Water Supply: Connect a water line from your sink through an inline filter into a keg
  2. Carbonation: Attach a specialty Soda Carbonator Lid to the keg with continuous CO₂ pressure
  3. Dispensing: Connect a faucet or beer tap to dispense cold, refreshing sparkling water
  4. Refrigeration: Place everything in a refrigerator to keep the water cold

The system automatically refills and recarbonates itself as you dispense water. You’ll need a refrigerator to house the system, and the assembly takes about 3 hours.

Shopping and shipping time: Varies, <1 week
Assembly time: 3 hours

A fan site for sparkling water! I’m a guy who loves sparkling water and got tired of incrementally carbonating 1 liter bottles. After building my own system, I wanted to share what I learned so more people can enjoy convenient, on tap sparkling water at home.
