Guide to Cloudy Water: Causes and Solutions
Cloudy water is a common issue that many people face in their homes. It can be alarming to see discoloured water coming out of the tap, especially if it looks murky as well. However, in most cases, cloudy drinking water is completely harmless and can be easily fixed.

Causes of Cloudy Water
There are several reasons why tap water may appear cloudy. Some of the most common causes are environmental factors and chemical reactions.
Environmental Factors
Environmental factors, such as air bubbles and sediment, are one of the most common causes of cloudy water.
Tiny air bubbles can get trapped in the water pipes and create a milky appearance when the water comes out of the tap. This can happen when there is a change in the water pressure, for example, after a repair or maintenance work has been done on the water supply system. To fix the issue, it is recommended to turn on the tap closest to where the water enters the house and let it run for a few minutes. This should help release the trapped air from the pipes and clear up the water.
Sediment or rust in the water pipes can also have this effect. This can happen when there is a sudden increase in water pressure or a change in the direction of water flow, with sediment becoming suspended in the water and making it look discoloured. While this type of cloudy water is also usually not harmful, it is recommended to contact a plumber to investigate and fix the issue. Sediment can come from a variety of sources, including soil erosion, construction work, and natural disasters. When sediment enters the water supply, it can make the water appear cloudy or discoloured.
Chemical Reactions
Chemical reactions can also cause water to appear cloudy. One of the most common causes of cloudy water from chemical reactions is the presence of dissolved minerals. When minerals such as calcium and magnesium are present in the water, they can react with other chemicals in the water to form particles that make the water appear cloudy.
Another cause of cloudy water due to chemical reactions is the presence of chlorine. Chlorine is often used to disinfect water, but it can also react with other chemicals in the water to form particles that make the water appear cloudy.
Is it Safe to Drink Cloudy Water?
Cloudy tap water is normal, but is it safe to drink? The answer is not straightforward, as it depends on the cause of the cloudiness.
If the cloudiness is caused by air bubbles, it is usually harmless and safe to drink. According to SpringWell Water, air bubbles can enter the water supply when the pressure in the pipes changes. This can happen when a water main breaks, or when there is high demand for water in the area. The good news is that air bubbles usually dissipate within a few minutes, and the water will become clear again. If you are unsure whether the cloudiness is caused by air bubbles, you can ask your neighbours if they are experiencing the same issue.
However, if the cloudiness is caused by other factors, such as sediment, it may not be safe to drink. Sediment can enter the water supply from a variety of sources, including old pipes, construction work, and natural disasters. This sediment can potentially contain harmful bacteria, viruses and more. If you suspect that the cloudiness is caused by sediment, it is best to avoid drinking the water until the issue is resolved.
If you are unsure of the cause of cloudy water coming from your tap and you want to act as safely as possible, it’s best to contact a local plumbing professional for advice.
Methods of Clearing Cloudy Water
There are several effective methods for clearing cloudy water, including filtration methods and chemical treatments depending on what type of water you’re treating, i.e. pool water versus drinking water.
One of the most effective ways to clear cloudy water is to filter it. This can be accomplished by cleaning or replacing the filter, adding a clarifier or running the water through an external water filter.
Water Filters
For cloudy drinking water, you can run the water through a filter. There are many products on the market for this, including filters that are installed directly to your taps or water pipes, as well as external filter jugs and containers.
If you have a dirty or clogged filter on your tap or in your pool, this can impede the flow of water through the system, leading to cloudy water. Cleaning or replacing the filter can help improve water clarity. It is recommended to clean or replace the filter at least once a year or as needed.
Adding a Clarifier
A clarifier is a chemical that helps to coagulate small particles in the water, making them easier to filter out. Clarifiers can be added directly to the pool water and are available in liquid or tablet form. It is important to follow the manufacturer’s instructions when using a clarifier.
Using a Flocculant
A flocculant is a chemical that causes small particles to clump together, making them easier to filter out. Unlike a clarifier, a flocculant causes the particles to sink to the bottom of the pool. Once the particles have settled, they can be vacuumed out of the pool. It is important to follow the manufacturer’s instructions when using a flocculant.
Chlorine Treatment
Chlorine can be added to pool water to kill bacteria and other contaminants, which can help to clear cloudy water caused by organic matter. It is important to follow the manufacturer’s instructions when using this treatment.
pH Balancing
Imbalanced pH levels can also contribute to cloudy water. However, it is important to follow the manufacturer’s instructions when using pH balancing chemicals.
Can You Prevent Cloudy Water?
When it comes to preventing cloudy water there are few methods available, as many of the causes are out of your control. There are some things you can do though, including:
- Regular Maintenance: Regular maintenance is key to preventing cloudy water as much as you can. Keeping your plumbing in good working order is the best way to try and prevent cloudy water due to sediment.
- Good Filtration Practices: Good filtration practices are crucial to prevent or clear up cloudy water.
- Proper Water Balance: Proper water balance is essential to prevent cloudy water, especially in pools or home aquariums. This includes maintaining the correct pH level, total alkalinity, and calcium hardness. You can use a pool test kit to check the water balance and adjust it accordingly.
Key Takeaways
- Cloudy water often results from trapped air bubbles or sediment, usually harmless and can be resolved.
- Air bubbles enter through changes in water pressure, while sediment arises from soil erosion, construction, or natural disasters.
- Drinking water safety varies; air bubble cloudiness is harmless, but sediment could pose health risks.
- Solutions include running water to release air, and for sediment issues, contacting a plumber.
- Filtration, adding clarifiers, or chemical treatments like chlorine can clear cloudy water.
- Preventative measures include regular maintenance, good filtration, and proper water balance, especially for pools.
