Nothing throws off your day like noticing something odd in your home — especially when it’s something you use all the time. Maybe you go to fill a glass of water, and instead of the clear, refreshing drink you expect, you see cloudy tap water. Suddenly, you’re wondering: Why is my tap water cloudy? Is it safe to drink? Do I need to call a plumber?
This isn’t an uncommon issue, and in most cases, the cloudy appearance of your water isn’t anything to worry about. But that doesn’t mean you should ignore it.
So, how do you know if your cloudy water is harmless or a sign of a bigger issue? Let’s break down the common causes of cloudy water and what you can do about them.
Why Is Your Tap Water Cloudy?
A cloudy appearance in your tap water can be alarming, but it’s usually a temporary issue. The most common cause of cloudy water is tiny air bubbles trapped in the water. It happens when water pressure changes, like when it’s cold outside, or if there has been work on the pipes nearby. When you fill a glass, you might notice the water clears after a few seconds as the air bubbles rise to the top.
But air bubbles aren’t the only reason for cloudy water. If the problem persists, it could point to something more than just harmless air bubbles.
1. Trapped Air in the Water Supply
If the cloudy appearance comes from tiny air bubbles, your water is completely safe to drink. This often happens due to:
- High water pressure forcing air into the water
- Changes in temperature affecting dissolved air
- Recent work on plumbing fixtures or public water systems
To check if trapped air is the issue, fill a glass and let it sit. If the cloudiness disappears from the bottom up as the air bubbles rise, you’ve got harmless air bubbles — nothing to worry about.
2. Sediment or Minerals in Your Water
If your cloudy tap water doesn’t clear up quickly, there might be dissolved minerals like calcium carbonate, iron, or sand in your water. This is especially common if you have hard water. You might even notice white spots on dishes after washing them.
A water softener can help reduce the high concentration of minerals in your water. If you’re seeing brown or yellow discoloration along with the cloudiness, it could indicate iron or sediment from old pipes.
3. Changes in Water Flow or Pressure
A sudden change in water pressure is also a common cause of cloudy water. Shifting water pressure can cause cloudy water by stirring up sediment in the pipes. This can happen if:
- Your water supplier is working on the lines
- There’s been a recent increase in water usage in your area
- You’ve had work done on your home’s plumbing
If your water pressure seems off and you’re experiencing cloudy water, contact your water supplier or a professional plumber to determine if there’s an issue with the pipes.
4. Water Heater Issues
If you notice that your hot water is cloudy but cold water is clear, your water heater might be the likely cause. Over time, sediment and minerals can build up inside your water heater, making your hot water look cloudy or even smell a little off — sometimes like rotten eggs.
Flushing your water heater can help remove any sediment buildup. If the problem persists, it might be time to call a plumber to inspect it.
5. Bacteria or Contaminants in the Water
While cloudy water is usually harmless, there are cases when it could indicate a bigger issue, like bacteria or other contaminants. If your water also has a strange taste or smell, it’s worth getting it tested. In some cases, a water filter or treatment system can help, but it’s best to consult a professional first.
Can Cloudy Water Make You Sick?
Most of the time, cloudy tap water caused by air or minerals is completely safe to drink. But it’s better to be cautious if your water has an odd taste, strong smell, or strange color.
Signs that your cloudy water might not be safe can include:
- A lingering smell
- A metallic or earthy taste
- Cloudiness that doesn’t go away after sitting
- Other changes in your water, like brown or yellow discoloration
If you’re concerned, try using bottled water for drinking water until you figure out the cause of the cloudiness. You can also get your water tested by a professional.
