The water dispenser in a refrigerator gets its water supply from a water line that is connected to the household's plumbing system. Here's how it works:
Water Line Connection: When you first set up your refrigerator with a water dispenser and ice maker, you'll need to connect it to a water source. Most modern refrigerators have a water line built into the back of the unit. You can attach a water supply line (usually provided with the refrigerator) to this connection point.
Household Water Supply: The other end of the water supply line needs to be connected to the household's main water supply. This is typically done by tapping into the cold water line under the kitchen sink. Some homes may have a dedicated water supply valve for the refrigerator.
Water Filter: Many refrigerators with water dispensers also have a water filter located inside the refrigerator compartment. This filter helps remove impurities and improve the taste and quality of the water dispensed. The water passes through this filter before reaching the dispenser.
Water Reservoir: Once the water line is connected, the refrigerator has a small water reservoir or storage tank inside the unit. This reservoir holds a certain amount of chilled water, making it readily available for dispensing without having to wait for the water to be chilled each time you request a drink.
Dispensing Mechanism: When you activate the water dispenser, the refrigerator's internal pump or valve system draws water from the reservoir, passes it through the filter (if present), and dispenses it through the dispenser nozzle on the front of the refrigerator.
By connecting the water dispenser to the household's plumbing system, you can enjoy fresh and cold water without the need for additional water bottles or pitchers. It's essential to replace the water filter regularly (if your refrigerator has one) to maintain water quality and avoid any potential issues with taste or odors.
