Yes, you can use standard tap water in your residential ice machine or refrigerator ice maker, as they are engineered to connect directly to municipal household water supplies. However, if your local tap water has high mineral content or hard water scale, it will leave calcium deposits inside the machine over time, leading to cloudy ice cubes and clogged water lines. Using a filtered water supply or installing a dedicated inline water filtration system significantly improves ice clarity, taste, and machine longevity.
