Why does hot water look cloudy

When you turn on a faucet and milky-white water comes out, you may be justifiably concerned about what’s going on and whether the water is safe to drink. There are a couple of possible reasons why you have cloudy tap water, but the good news is, it doesn’t usually pose a health risk.

What Causes Cloudy Tap Water?

Most often, tap water that looks cloudy or milky contains air. If it’s coming from the pressurized municipal system, you’ll notice cloudiness at all of your cold water taps. Cloudy water from a single fixture usually points to an issue with the aerator or faucet. White, cloudy hot water can indicate a problem with your water heater. Here’s how to troubleshoot cloudy hot and cold water so you can deal with the underlying cause.

Cloudy Water from Cold Tap

To check where the problem originates, run each cold water tap in your home for a few seconds then fill a clean glass.

If the water from most or all of your fixtures is cloudy, it’s likely caused by air in the municipal supply. Let each glass sit for a few minutes and the water should clear from the bottom up. If you’re still seeing a cloudy flow after 24 hours, call the water bureau to ask if there’s maintenance being done, or a possible leak in the system.
If cloudiness is only occurring at one faucet, take off the aerator, clean it with a 50-50 water/vinegar solution then rinse it thoroughly and reinstall it.

Why is My Hot Water Cloudy?

To find out why your hot water looks milky, let it run briefly then fill a glass. If the cloudiness dissipates from the bottom upwards within a few minutes, it’s simply due to pressurized air being released. However, if the water clears at the top first and particles settle to the bottom, have the water heater checked. A professional plumber may tell you it needs flushing to remove sediment, or the dip tube needs replacing.

There’s nothing like pouring a nice clear glass of water, but what if the water is not as clear as you’d hoped? Cloudy water is not an uncommon occurrence, especially if it’s hot water.

Since it’s the hot water that’s mainly affected, you may blame the water heater first, and although the water heater may be to blame, there are also other possibilities. Read on to find out what causes cloudy water and some simple ways to fix it.

What Causes Cloudy Water?

Water molecules consist of hydrogen and oxygen. When heated, they expand. During expansion, other molecules and smaller particles are trapped, which causes the water to look cloudy. Essentially, bubbles created during the expansion are what cause the cloudy look. So why doesn’t the water always look cloudy? Pressure.

The buildup – and sudden release – of pressure is what causes the separation of molecules, which in turn creates bubbles. Note that air bubbles created this way are not the same thing as air in your hot water lines. Also, pressure isn’t the only culprit.

Here are some common causes:

Dirty Aerator

The aerator is found at the tip of the faucet. You can usually twist it off easily. When sediment builds up and blocks the path of flowing water, it creates unwanted pressure. This pressure creates more bubbles and makes the cloudy look in the water.

Sediment Buildup in the Water Heater

Sediment will build up in your water heater, and the only way to limit this is by flushing the hot water heater or using a water filtration system. Sediment gathers on the anode – or element – and limits its potential.

Eventually, the sediment flakes off and settles to the bottom of your water heater. It continues to accumulate over the years until it’s flushed or it eats through the bottom of your water heater.

Heating Up the Water

Heating the water will likely produce cloudiness. If you look into a pot of water on the stove, you’ll see it cloud over from the bubbles. Depending on how hot you have your hot water heater set, it could produce the same effect from your faucet.

The Rare Winter Effect

It’s not common, but water on the verge of freezing can cause cloudiness. There aren’t many freezing days in Plano, but it does happen. If you look at the cloudiness in a piece of ice, you can see the effect cold has on water. Cloudiness in cold water may be a sign of something serious or that you need to insulate your pipes better.

Outside Sources

You may not have cloudy water, but instead, it may look tinted or even muddy. If your municipality is doing work to the outside pipes, there is a chance you may get some ugly-looking water, but it shouldn’t last for more than a couple of hours.

If you notice irregularities after heavy rain, then there may be something wrong with your pipes, and you should call a professional plumber immediately.

How to Determine if Your Cloudy Water Is a Concern

Cloudy water could be nothing, but it could also be serious. Luckily, there is a simple method to determine whether your cloudy water is a concern.

Get a see-through container. This container can be a glass, bowl, or Mason jar.
Turn on your water till it’s hot.
Fill the container to at least three-quarters of the way full.
Set the container on a flat surface and watch it.

Air is lighter than water and will rise to the top. If the cloudiness is primarily air, you will notice the bottom of the container clears, and the rest of the container will be void of cloudiness within a couple of minutes.

Sediment is heavier than water and will settle to the bottom of the container. With sediment, the top of the container will clear first. It will also take much longer for the container to clear since the hot water makes it difficult for the sediment to reach the bottom.

How You Can Fix Cloudy Water in Your Plano Home

Though it’s easy to blame the water heater, it’s actually the aerator that’s to blame in many cases. One of the simplest ways to find out and possibly even fix the problem is by removing and cleaning the aerator. To do this:

Remove The Aerator From The Faucet

The aerator should unscrew from the faucet by turning clockwise. You may need to use a wrench if it won’t come off easily using your hands. If you can’t remove it by hand, it’s best to contact a professional plumber, as they can remove it without causing damage.

Clean The Aerator

After you’ve removed the aerator, give it a thorough visual inspection for any dirt and debris that may be caked onto it. Use a washcloth to remove the loose gunk.

There are small mesh holes inside the aerator where sediment deposits can get lodged. Use a toothpick, paper clip, or small needle to dig them out. If they aren’t coming out easily, or you want to be thorough, soak the aerator in white vinegar overnight to loosen the debris.

Rinse It Out

Once the aerator is cleaned out, give it a good rinsing before placing it back onto the faucet. Hold the aerator under running water to rinse away any lingering debris that became loosened and may be trapped within it.

Replace The Aerator

When it’s clean and all ready to go, simply screw the aerator counterclockwise back onto the faucet using your hands to get it as tight as it will go.

Test The Water

It’s time to see if your efforts paid off. Turn on the hot water and allow it to run for a minute to see if the water is still cloudy. If it is, it means there’s a bigger issue at hand, likely something to do with your hot water heater. A plumbing professional will need to come in and inspect the hot water heater to help diagnose the problem.

Have you ever noticed your hot water is cloudy or has a "milky" look? Cloudy water, besides looking unappealing, can leave you worried about health risks, as well as what it may be doing to your plumbing and other water-use appliances.

This article will answer the question of why your hot water is cloudy, and if there are any health or safety concerns you should to be concerned about. We'll also give you a few suggestions on how to fix the problem.

What Causes Hot Water to Be Cloudy

There are two main reasons why your water is cloudy. Let's take a close look at each:

Reason #1: Tiny Air Bubbles

The most common reason your tap water is cloudy is due to tiny air bubbles, which is a result of either a temperature change or an increase in water pressure.

If your cloudy water was caused by air bubbles, then your water is perfectly safe to drink. In fact, within a few minutes the cloudy effect from the bubbles should dissipate and your water will be clear again.

Temperature Changes

If you notice your hot water is cloudy, the problem is probably due to the temperature fluctuation from heating the water.

When water is heated it expands and can trap gases in tiny bubbles and give a cloudy appearance.

However, once you draw a glass of water, the pressure is reduced and the bubbles rise to the top and dissipate. Leaving you with a clear glass of hot water.

Water Pressure

An increase in water pressure can be another cause of cloudy water.

The cloudy or milky look to your water could be the result of tiny air bubbles that come from either a pressurized municipal water system or a partially blocked faucet or aerator.

If the problem is coming from the municipal water system, your water should be cloudy at each tap throughout your house. However, if only a single fixture dispenses cloudy water, then the odds are in your favor that it's a faucet or aerator issue. Which is much easier to fix.

How to Determine the Cause of Cold Cloudy Water

To determine where the problem is originating, simply run the cold water for about 15 seconds at each faucet before filling a glass. Set the glass down and allow it to sit for a couple of minutes.

If the problem is from the municipal water supply, you'll have cloudy water in multiple locations. As the glass sits, you should see the water begin to clear from the bottom to the top.

If the water in the glass is still cloudy after 24 hours, check with the water bureau. It's possible there's maintenance work being done. It's also possible that there's a leak in the system.

When only one faucet has cloudy water you can remove the aerator and soak it overnight in a solution of 50% water to 50% vinegar. If that doesn't break-up the blockage, you can purchase a new aerator from Amazon or your local hardware store.

If it's been awhile since you've flushed your water heater you probably have a build-up of sediment that's not only lowering the efficiency of your heater, but also causing your hot water to look cloudy.

All water contains minerals, and the heavier the mineral count in your water, the harder the water. Some areas are particularly prone to hard water and need to take steps to treat the incoming water before it enters the house.

As the water heats within your water heater the minerals separate and attach to the inside of your water heater. This is called lime scale, and you've likely noticed a white scaly film on your dishes or chrome water fixture.

Lime Scale is simply a build-up of minerals. It's not dangerous, but it can cause your hot water to be cloudy since it'll eventually flake off and collect at the bottom of your water heater tank.

This collection of flaked-off lime scale is called sediment, and it can travel through your plumbing and clog showers and sink aerator, making it more difficult for water to pass.

Sediment can also find its way into your glass leaving the water with a cloudy look.

If it's been awhile since you've flushed your water heater, then there's a good chance your cloudy hot water is caused sediment.

How to Check if Sediment is Causing Cloudy Hot Water

Open a hot water tap and let it run for about 15 seconds before filling a glass. Then place the glass on a flat surface for observation.

If within a few minutes, the cloudiness of the water dissipates beginning at the bottom and moves to the top, the cloudy water is caused by tiny bubbles from pressurized air.
If the water at the top clears, but particles settle at the bottom of the glass, then the problem is most likely from sediment within your water heater.

Is Cloudy Water Safe to Drink?

When your cloudy water was caused by tiny bubbles and clears after sitting a few minutes, then your tap water is absolutely safe to drink. Safe drinking water should be clear and without a funny taste or smell.

When your water is cloudy due to sediment, and remains cloudy after flushing your water heater, it's a good idea to contact a professional plumber to troubleshoot the problem just to play it safe.

In most cases, the minerals, calcium and/or magnesium, which causes water to be hard, are not a health risk. But there may be something else going on that should be addressed.

It's important to note that cloudy water isn't typically a health concern, although it could be an indication of unsafe chemicals or pathogens.

If your water is orange, yellow, or brown, call a professional to find out what's going on. You should absolutely not drink the water as it may contain harmful chemicals.

How to Fix Cloudy Hot Water

After diagnosing what caused the cloudy water, you'll want to take action to fix the problem.

Clogged Aerator

If the issue was due to a clogged aerator you can try to clear the blockage by removing the aerator and soaking it overnight in a 50/50 solution of vinegar and water.

This might buy you some time, but unfortunately, once an aerator becomes clogged they tend to clog again. So it's typically best to purchase a new one through Amazon or your local hardware store.

One thing to consider is that the aerator may be clogged because of sediment from the water heater. If this is the case, it'll only clog again. In order to fix the problem, you'll need to address the root cause and flush your water heater.

Water Heater Sediment

Water heaters should be flushed periodically to remove the sediment at the bottom of the tank. Not only does sediment have the potential to cause your water to become cloudy, but it also shortens the water heater's service life and reduces their energy efficiency.

Flushing your water heater isn't a difficult task, but if it's been awhile since it's been done, the sediment could clog the drain valve. This article will give you several solutions if you run into that problem.

Of course, some homeowners prefer to hire a professional, who will be able to both flush your water heater and ensure your water is no longer cloudy.

Adding a sediment filter that filters the incoming water is also a good idea. Read our article on sediment filters.

Hard Water

If you live in an area that has hard water, then your water-using appliances, (such as dishwashers, water heaters, and washing machines) are exposed to the harmful damage of lime scale.

We highly recommend installing a water softener or other device to help decrease the lime scale build-up that will develop on all surfaces water comes in contact with. This article goes into detail on the causes and affects of hard water and lime scale. It also provides you with a number of preventative options.
