You feel thirsty, so you grab a glass to get some water from your tap faucet. But as you turn it on, instead of getting clear crystal water, you notice a “milky” cloudy water in your cup.
So, what’s going on? Well, usually there’s no cause for alarm.
The cloudiness is usually caused by trapped tiny air bubbles that escape after a while taking the “cloud” with it.
Why your hot water is cloudy
To get the full picture, you have to understand that water is stored in your water pipes under pressure.
This pressure allows gases and oxygen to get dissolved in the water. As the water gets heated, it slowly loses its ability to hold or contain these dissolved gases.
In your water heater, these air bubbles from gases and oxygen look for a way to escape under the intense pressure. That’s why as soon as you turn on your tap, you notice a cloudy appearance at the top.
This is caused by the air bubbles trying to escape back into the air.
How your hot water turns cloudy.
In most cases, milky hot water is the result of dissolved oxygen and gas bubbles trying to escape.
However, there are two other reasons. In this section, we’ll go over all three of them.
Heating the water.
Lole we’ve discussed, water heaters reduce the capacity of water to contain the dissolved gases and oxygen.
This creates room for the air bubbles to find an escape route. When you turn on your tap, this route is created and the bubbles frantically find a way to get out.
Think of it like when you pop a bottle of champagne after shaking it for a while. At first, it’s a bit foamy but settles down and clears up later.
The faucet aerator.
Each tap comes with a tiny metal or plastic screen cap that fits at the end of the faucet.
It’s designed to reduce the amount of splash and shape the water stream so it’s straight and evenly pressured.
Sometimes, this aerator gets clogged up and the pressure increases causing your hot water to be cloudy.
Other times, it can get dirty from mineral contamination if you have hard water. This will lead to your water being cloudy too.
Presence Of Sediment.
Due to the nature of water heaters, the pressure build up can lead to an increase in sediments of minerals over time.
When this happens, your water turns out cloudy. If you notice that this is the cause, it’s best to contact your local water maintenance and stick to bottle water instead.
Any health concerns related To drinking or using cloud water? Use this DIY test
To help you decide, you’ll need to perform a simple test at home.
Take a transparent glass of water from your tap and leave it for a few minutes. If it clears up from top to bottom, then yes it’s safe to drink or use for cooking.
However, if it stays cloudy for long hours most likely at the bottom, then there’s a high chance it has been contaminated with sediments, rust or sand.
On a side note, if water from most faucets in your house is cloudy, then it’s likely caused by the municipal supply in your area. Most likely a switch from well source.
Easy ways to fix cloudy hot water.
Before you spend a ton of money hiring water services, you can troubleshoot to reduce or eliminate the occurrence of cloudy water.
These are simple fixes you can carry out easily.
1) Flush your water tank
Over time, sediments and calcium deposits build up at the bottom of your water heater. This results in clogged pipes and cloudy water.
To fix this, drain your water heater and allow water to flush through the heater so all the sediments are removed.
2) Fix your aerator.
Sometimes the aerator of your faucet can get clogged up causing you to experience cloudy water.
First step will be to remove the aerator by turning your faucet clockwise. Then, washing up so that every sediment stuck on it is removed.
By the time you put back the aerator, you’ll get back your clear crystal water once again.
3) Check your water heater anode.
All water heaters come with an anode rod that attracts and removes sediments and rust from the water being heated.
As with all things, the anode rod will wear off and lose it’s capabilities. This will result in a build up of sediments. That’s why it’s important to make sure your anode rod is still functioning. If it’s not, then it should be replaced.
