Why Is The Water Gray After Installing New Water Filter?

Have you ever noticed that the water from your tap is a bit gray after installing a new water filter? This is not only an unsightly problem but can also be concerning for those without much knowledge about plumbing.

The cause of this strange phenomenon is usually caused by air pockets becoming trapped in the filter housing. This occurs when the filter is installed improperly. The air can mix with the water and cause it to look gray.

In some cases, the water may appear grayish or cloudy after installing a new water filter. Air bubbles generally cause this in the lines that can be created when changing an existing filter system. The trapped air causes the water to take on a grayish hue but doesn’t indicate contamination. The best way to get rid of the grayish hue is to run the tap until it clears up simply. This may take a few minutes, but after running the water for a while, it should look clear again.

The gray color of your water may be coming from newly installed plumbing.

Is The Refrigerator Connected To A Cold Water Supply Line?

When installing a new water filter, you may notice that the refrigerator’s water is cloudy or gray.

Was The Water System Flushed After Filter Installation Or Replacement?

If the water system wasn’t flushed after a filter was installed or replaced, that could be why the water is coming out gray.

Flushing the system can help to eliminate this issue.

Is Your Filter Marked With Whirlpool Or Every Drop?

If your water filter is marked with Whirlpool or Every drop, activated carbon particles from the new filter likely cause the gray color of your water.

These particles are harmless and will dissipate over time, but they can cause your water to be discolored.

Flushing your filter helps reduce the grayish color in the water and ensures that you’re drinking clean, clear water.

How Can Dangerous Be Gray Water?

This should be done at least once a month to keep your water clean and clear.

Doing so can help ensure that your home’s water supply remains clean and clear.
