Continuous Soda Carbonator Keg Lid

Enjoy a never-ending supply of soda water on tap with the Continuous Soda Carbonator Keg Lid. SodaStream units are great, but filling up those tiny 1L bottles is a pain, they're expensive to swap, and they run out quickly. Hook up your mains water supply to this Carbonator Keg Lid, compatible with any standard ball lock homebrew keg, and you'll never have to think about running out of sparkling water.

1. Position the keg inside your fridge or kegerator (ideally below 40°F).
2. Attach your beverage draft line to the soda water out post.
3. Attach your gas line to the gas-in post.
4. Set your CO2 regulator to 30-50 psi, depending on how highly carbonated you like your soda water. We highly recommend using a check valve on your CO2 line.
5. On first use, purge the air from the headspace of the keg.
6. Connect the mains water to the water inlet post on the lid of the keg.

We recommend also using a check valve on your mains water line to prevent soda water from going back into your house mains. Depending on your mains water pressure, you may need to reduce it using the Duotight In-Line Regulator. For the Carbonator Keg Lid to work well, the mains water pressure should be 30-40 psi higher than your regulator set pressure (from Step 4).

That's it. This simple unit will give you continuous soda water connected to your mains water.

Please note: if you are using a CO2 regulator that uses a corny-style PRV, such as the KOMOS® regulator, you will need to swap out the standard Green PRV with the 0-100 psi Gray PRV so you can raise the pressure above 60 psi. Always check the pressure rating of your keg(s) before swapping the PRV.
