Check the CO2 Tank: Make sure it’s properly connected and has enough gas. Sometimes, even if a tank feels full, it might not be delivering enough pressure.
Examine the Carbonator: Look for any leaks or cracks in the unit itself. A leak could prevent proper carbonation.
Clean the Nozzle and Tubing: Over time, sediment or mineral buildup can affect performance. Clean the nozzle and any tubing that connects the CO2 tank to the bottle
Check the Pressure Regulator: If your carbonator has a pressure regulator, it might be malfunctioning. You might need to get it repaired or replaced.
