How to Get Rid of a Metallic Taste in the Water Line From the Fridge
Dec 08, 2016
Water that tastes like metal when it comes from the refrigerator has a sharp, biting flavor. High iron content in your water supply can contribute to this problem when you use well water. But if you receive water from a municipal source, the problem might be with the line supplying your refrigerator. To get rid of the metallic taste in your water, review the possible causes and choose the method that works for your situation.
Water that sits in the refrigerator's copper supply line without movement begins to taste metallic. To freshen the water in the refrigerator's water supply line, empty the line by filling up and dumping several glasses of water from the refrigerator. Then fill a glass and taste it. The water should taste better. Periodically dump the water from the refrigerator line to keep the water supply fresh or increase usage from the refrigerator. This also changes the taste of the ice cubes.
The copper tube that runs from the wall to your refrigerator can contribute to a metallic taste in the water. To get rid of the metallic taste, exchange the copper tubing with plastic tubing. Measure the length of the copper tubing to figure out how much plastic tubing you will need. Verify the plastic tubing is acceptable for use with as a refrigerator water supply line before buying it. Most home improvement or hardware stores carry plastic water supply lines for refrigerators.
Newer refrigerators come equipped with a built-in water filter. When the refrigerator filter needs replacement, some refrigerators emit a red light on the front of the refrigerator's water dispenser. This signal comes on approximately once in a six-month period. Follow the manufacturer's instructions for replacing the water filter. The filter is usually found in the refrigerator compartment near the top or bottom of the refrigerator. Check with a home improvement or hardware store for replacement filters. If a replacement is not available locally, you can find one at an online plumbing or hardware supply site.
If none of these solutions works to change the taste in the refrigerator line, it could be the water supply for the entire house requires filtration. Municipal water supplies only treat water for health reasons, not for taste and odor. Adding a whole-house carbon filter at the water's entry point to your home can remove metallic tastes from municipal water. For homes that rely on well water, the water's metallic taste requires a water treatment system installed by a professional.
