The home devices are adjusted in such a way that a maximum of 1 litre of sparkling water can be tapped in a single session. After that, it is recommended to wait 10 seconds for the next litre. The Professional devices allow you to tap 3 litres of sparkling water in one tap.
If more water is tapped, the device will fail and it is possible that only CO2 will leave the device.
If this happens, all you have to do is wait a bit. Then you can operate the device again. Please take the 1-litre limit into account.
