Why is water bubbly coming from refrigeration dispenser?

Bubbly water from a refrigeration dispenser is typically due to carbon dioxide being infused into the water, creating carbonation. This can occur if the dispenser is designed to provide sparkling water or if there is a malfunction in the system that introduces excess air or gas into the water line. Additionally, temperature fluctuations can cause dissolved gases to escape, resulting in bubbles. If the bubbling is unexpected, it may be worth checking the dispenser for any issues or consulting the manufacturer's guidelines.
