Why Is My Tap Water White? 7 Shocking Reasons

Why is my tap water white? Well, White water from the tap can make you anxious about the safety and quality of your drinking water. There are several reasons why your water may turn white. In most cases, the whiteness or cloudiness doesn’t pose any health risk. Still, we recommend testing your water on regular basis to settle all doubts.

So, Why Is My Tap Water White? What Causes White Water?

Your tap water is white because of Excess air bubbles. The Excessive trapped air in your main water supply or pipes causes pressure build-up that eventually form air bubbles. When you switch on the tap, you’ll release the built in pressure forming these air bubbles that are responsible for the whitish water appearance. Fortunately, this water is safe.

Other Reasons that Could Make Water White

High Concentration Of Total Suspended Solids (TSS)

TSS are small particles that remain suspended, those that don’t settle down in water. They include, silt, iron, algae, and manganese among others. These elements can cause unusual water whiteness or cloudiness leading to bacterial growth.

You can use a whole House water filter to get rid of the suspended solids.

Hard Water Causes White Water

If you have hard water, you may notice cloudy or white water coming from your faucet. How will you know you have hard water?

  • You’ll notice white spots on utensils after washing
  • When you put water in a glass the whiteness doesn’t clear up
  • Buildup of mineral deposit on your water appliances
  • Using more laundry detergent and clothes are stained

You can consult a professional to install a water softener unit. The softener can remove the excess mineral in the water making it clearer and safe for drinking.

Repair Works

If your water utility company is doing some repairs on the water distribution system, you’re likely to feel the effect. You’ll notice the water coming from your faucet is white or cloudy.  This should clear up after the repair work is complete.

The Hot Water Heater

Excess trapped air in the water heater can cause the white water. Heating water increases the speed of releasing the trapped air.

Water Pressure

Water from the treatment plant is usually pressurized to allow it reach the various destinations (homes). Water under pressure carries excess air. Therefore, when this pressurized water comes out of your faucet, it’s no longer pressurized thus the air comes out as bubbles similar to how a carbonated drink behaves. The solution would be to allow the water settle in a container and the bubbles would disappear naturally.


In some instances, the white water is because of accumulation particles or sediments that find their way into the water system. Tiny particles like grit or sand can get into the water if the filtration system is not effective. Hence, you’ll notice white water.

In addition, poorly maintained wells can also deliver discolored water. The particles settle at the bottom of the water, making the water white. You can install a sediment filter to get rid of the particles.

Methane Gas

Although a bit, unusual methane gas can also make water white.  The wells in regions that produce oil or gas are at an increased risk of methane gas. Methane is combustible, odorless, tasteless, and colorless. Hence, it’s difficult to detect its presence in water.

Methane in water is dangerous as it performs similarly to water with trapped water. The methane will produce air bubbles, rise upwards and disappear. An individual is likely to confuse it with water with trapped air. You need Well-ventilated aeration water system to remove the methane, as it’s highly flammable.

As we’ve said above, have your water tested, if you’re unsure about the quality and safety of the water.

Is White Water Safe to Drink

You should take appropriate action to deal with any water discoloration. White water that is because of trapped air may not pose any health effects. You just need to allow the water sit for some time and the whiteness clears naturally. However, water that is brown, green, or even yellow may be contaminated.

White water that’s as a result of hard water can cause mineral buildup on fixtures, pipes, lessen the life of appliances, and lower the effectiveness of laundry detergents. Nevertheless, hard water is not bad; in fact, it has essential minerals needed by the body. Its only problem is its negative effect on appliances. Hence, most people choose to install water softeners instead.

There are many reasons why your tap water may change color. Therefore, The bottom line is to have the water tested to settle all doubts

How to Fix White Tap Water

First, fill a glass with water and allow it to sit for a period may be 5 minutes. Look at how the cloudiness or whiteness clears. If it’s from bottom to top, its only means the water has excess air, hence, the whiteness. The air bubbles will rise to the top and the whiteness disappears.

You can also find out from your neighbor if they are also experiencing the same issue. If they confirm that they also have white water coming out of the tap, then the problem might be the main water supply. Have your water supplier fix the problem.

If your water supplier detects water contamination, you can install a sediment filter or a faucet filter. Until your water is confirmed safe use bottled water of find other ways of obtaining safe water, otherwise don’t drink questionable water.

On top of that, you need to check the tap’s aerator. The aerator is a small-screened cap that sits on the faucet. Its aim is to reduce water splash. The aerator can clog If not continuously checked, hence increasing the tap pressure that eventually causes the hot water become white.

Another thing you can do to fix the white water issue is to check the pressure of the hot water tank. It’s advisable that you flush the hot water tank. Alternatively, assess if its anode is working optimally. These simple tasks will extend the life of the appliance and reduce or eliminate the white water menace.


As we’ve mentioned above, white water coming from the top is mainly as a result of tiny air bubbles. This water is not harmful to health.  Although you might notice discolored water on various occasions, you should not take water discoloration lightly. Have the water tested for contaminants or impurities.
