For the delivery of sparkling water, a CO2 cartridge is coupled to your system. A standard cartridge of 1100 grams is sufficient to produce no less than 200 litres of sparkling water.
When the sparkling water starts to run much slower (more than 30%) and the cold water continues to run just as fast, the gas cartridge (CO2) will be almost empty. You can also tell by the taste: the water will be less sparkling and no longer sparkle in the end.
You can easily replace an empty CO2 cartridge yourself. You order it from AQUALEX, after which it will be delivered to your home as soon as possible via DPD. Note that during the annual maintenance the technician always carries cartridges with him and can therefore also leave some on request
