How to flush refrigerator water line?


Flushing the refrigerator water line is an essential maintenance task that helps ensure clean and fresh-tasting water from your dispenser or ice maker. Over time, mineral deposits, bacteria, and other impurities can accumulate in the water line, affecting the quality of the water. In this article, we will explore the steps to properly flush your refrigerator water line, ensuring optimal performance and water quality.

Materials Needed

Before we begin, gather the following materials:

– A clean container or bucket
– A towel or rag
– Distilled white vinegar
– Clean water

Step-by-Step Guide

Step 1: Turn off the Water Supply
Before starting the flushing process, locate the water supply valve for your refrigerator and turn it off. This valve is typically found behind the refrigerator or under the sink. Turning off the water supply will prevent any water from flowing into the refrigerator during the flushing process.

Step 2: Empty the Ice Maker
If your refrigerator has an ice maker, empty the ice bin to ensure that no ice cubes or debris interfere with the flushing process. Dispose of any ice cubes in the bin and clean it thoroughly.

Step 3: Locate the Water Line
Next, locate the water line at the back of your refrigerator. It is usually a small, flexible tube that connects to the water supply valve and the refrigerator’s water inlet valve. Take note of any connections or fittings that may need to be disconnected for easier access.

Step 4: Disconnect the Water Line (if necessary)
If there are any connections or fittings that hinder access to the water line, carefully disconnect them. Use caution and refer to your refrigerator’s manual for specific instructions on disconnecting the water line.

Step 5: Flush with Vinegar
Fill a clean container or bucket with a mixture of equal parts distilled white vinegar and water. Submerge the water line into the container, allowing the vinegar solution to flow through the line. Depending on the length of the water line, you may need to use a funnel or other suitable method to pour the solution into the line.

Step 6: Let the Vinegar Solution Sit
Allow the vinegar solution to sit in the water line for approximately 10-15 minutes. This will help break down any mineral deposits or bacteria that may have accumulated.

Step 7: Flush with Clean Water
After the vinegar solution has had time to work, flush the water line with clean water. Connect the water line back to the refrigerator if it was disconnected. Place the end of the water line into a sink or bucket and turn on the water supply valve. Let the water flow through the line for a few minutes, ensuring that all traces of vinegar are flushed out.

Step 8: Check for Leaks
Once the water has been running through the line for a few minutes, check for any leaks or drips. Inspect the connections and fittings to ensure they are secure and tight. If any leaks are detected, tighten the connections or replace any faulty parts.


Regularly flushing your refrigerator water line is an important maintenance task that helps maintain the quality of your water supply. By following these simple steps and using common household materials, you can ensure that your refrigerator dispenses clean and fresh-tasting water. Remember to consult your refrigerator’s manual for specific instructions and always prioritize safety when working with water lines.
