You may begin to wonder if this is normal or if there is something wrong with your water supply. Find yourself wondering, why is my hot water cloudy? It could be due to air bubbles, mineral deposits, dissolved gases, or water heater issues.

Is Cloudy Tap Water Safe to Drink?

One of the primary concerns when dealing with cloudy tap water is its safety for consumption. In most cases, cloudy water is not a health hazard and can still be safe to drink. However, if the cloudiness is accompanied by an unusual smell, taste, or discoloration, it is recommended to err on the side of caution and consult a professional.

While generally safe, it’s essential to note that cloudy water may indicate an underlying problem with your plumbing system or water supply. It is advisable to address the issue promptly to ensure the continued safety and quality of your drinking water.

Why Is My Hot Water Cloudy?

Cloudy hot water can stem from various factors, and understanding these causes can help you determine the best course of action. Here are a few possible reasons why your hot water might appear cloudy:

  1. Air Bubbles: Air bubbles trapped in the water can cause it to take on a cloudy appearance. These bubbles often occur due to changes in water pressure or temperature and are typically harmless.
  2. Mineral Deposits: Minerals naturally present in water, such as calcium and magnesium, might accumulate over time and give hot water a cloudy or milky appearance. This is often referred to as “hard water” and is prevalent in areas with high mineral content.
  3. Dissolved Gases: Certain dissolved gases, such as oxygen or hydrogen sulfide, can cause hot water to become cloudy. This is commonly seen in instances where water has been sitting unused for an extended period.
  4. Water Heater Issues: Problems with your water heater, such as sediment buildup or a faulty heating element, can also result in cloudy hot water. If your hot water consistently appears cloudy, it may be worth checking your water heater for any issues.
Cloudy tap water can be due to various things such as a new filtration system or hot water issue.

How to Fix Cloudy Tap Water?

If you’re determined to improve the clarity of your tap water, there are several steps you can take. However, before attempting any remedies, it is crucial to identify the specific cause of the cloudiness. Here are some potential solutions:

  1. Flush the Pipes: Running cold water for a few minutes can help flush out any trapped air or dissolved gases that may be causing the cloudiness. This process can effectively clear up the water’s appearance.
  2. Install a Filtration System: Consider installing a water filtration system designed to remove excess minerals and impurities from your water supply. This can help eliminate cloudiness caused by mineral deposits and improve overall water quality.
  3. Inspect the Water Heater: If you suspect the water heater is the culprit, it may be necessary to have a professional inspect and service the unit. Regular maintenance can help prevent sediment buildup and ensure that your hot water remains clear and safe to use.

Other Recommended Maintenance

Now that you know about cloudy tap water, let’s take a look at a few other areas of recommended maintenance. One of those is fixing low water pressure. This can be due to leaking pipes, debris in pipes, or leaking pipes to name a few.

Another is shower water. Sometimes, the shower water ends up cold while the sink water is hot. This is due to a water heater malfunction or a bad shower mixer valve.

Lastly, it is necessary to flush a tankless water heater. To do this, turn off the power and follow the steps to make sure it is done correctly.

When Do I Call a Professional?

While attempting to fix cloudy tap water on your own can be a viable option, certain situations warrant the expertise of a professional plumber. If the cloudiness persists despite implementing the solutions mentioned earlier, it may be indicative of more significant issues with your plumbing system. Some signs that it’s time to call a professional include:

  • Persistently cloudy water with unusual odor or color.
  • A sudden drop in water pressure or flow rate.
  • Noticeable leaks or corrosion in pipes.

A professional plumber will be able to accurately diagnose the problem and recommend appropriate actions to restore the clarity and safety of your hot water.


Cloudy hot water can be a cause for concern, but in most cases, it is not a health risk. Understanding the potential causes of cloudiness, such as air bubbles, mineral deposits, dissolved gases, or water heater issues, can guide you in finding suitable solutions.

Whether it’s flushing the pipes, installing a filtration system, or seeking professional assistance, there are steps you can take to address this issue. Remember, maintaining the quality of your tap water is essential for the well-being of your household. While you are clearing up your water, it is a good time for a home inspection.
