Understanding Why Bath Water Turns Blue

Step #1: Light Reflection

The first cause of blue bath water isn't blue water at all but a trick of the eye due to how water reflects light. For pure white bathtubs, light (especially bluish light) reflects off the surface, making the water appear bluer than it actually is. This effect is amplified if there's anything blue in or even near your bathtub, such as a rubber drain, shampoo bottle, hanging towel, or loofah.

How to Fix It:

• Remove all blue items from the room, including items in the tub.
• Consider light reflecting off blue or pure white tiles.
• Switch out the light bulb in the room for a red one and see if the problem persists.
• Consider the time of day as sunrise and sunset have the most blue light.

Step #2: Copper in Water

Copper levels might be elevated in your water supply. There are a few reasons for this, but the most common one is older copper pipes. Over time, these pipes begin to break down and leak copper into the water supply. You may not notice this in shallow water such as in cooking pots or drinking glasses. It may only be visible in deeper water, like in a bathtub.

How to Fix It:

• Check if your pipes are made of copper.
• If they are, try flushing the pipes for 10 minutes to see if the problem is temporary.
• If the water remains blue, test the water.
• In cases of copper corrosion, you may need to either add a filter or fix or replace the copper pipe.

Step #3: Low pH Levels

The acidity of your water plays a large role in its color. While this problem is connected to the copper section above, they are two different issues. A low pH could cause corrosion of the pipes, leading to the release of blue-colored copper particles, but copper pipes could also degrade without acidic water.

When you test for copper levels, there will usually be a pH marker on the test strip telling you how acidic your water should be. Be aware that there is a range of acceptable pH levels, as certain cities (or wells) will have different ideas of what normal acidity means. A pH of around 7 is ideal.

How to Fix It:

• Use a home test kit to quickly and easily test pH. Take multiple samples from different faucets.
• A water softener can neutralize pH.
• Test the water coming into your home from the city or well. Call the city if you’re hooked into the municipal system.

Step #4: Cross-Connection

This isn’t the connection you want. When water is cross-connected, it means that water from your pool, toilet, hot tub, etc., has merged with your drinking water supply. This can introduce chemicals that turn your water blue, and it’s the least safe issue on this list—and the only one that needs to be addressed immediately.

How to Fix It:

• Call a professional. This isn’t a DIY project.
• The professional may install things like backup preventers or divert the water supply.

When to Call a Pro

Call a plumber near you right away if you think you might have cross-connected water. Some other reasons to call a pro are:

• If the blue tint hasn’t gone away with a flush cycle or after 24 hours.
• If you notice other signs of water quality dropping.
• If you observe older-looking pipes in your home.
• If there are any water pressure problems.
• If you notice any health issues like skin irritation.

Tips and Reminders

• Avoid Drinking: Even if the water appears blue due to light reflection, it's best not to drink it until you're sure of the cause.
• Test Regularly: Regular water quality testing can help identify issues before they become serious.
• Professional Help: For persistent problems, always consult a professional to ensure your plumbing system is safe and efficient.

Conclusion

Understanding the causes of blue bath water can help you maintain a safe and pleasant bathing experience. Whether it's a simple light trick or a more complex plumbing issue, knowing the cause allows you to take appropriate action.
