Why Is My Hot Water Cloudy?

why is my hot water cloudy from the hot tap for Whywait PlumbingCloudy, hot water looks yuck.

Why is my hot water cloudy is one of those perennial questions that arise for the plumbing technicians at Whywait Plumbing?

Generally, the problem is based around reoccurring issues of, “what do you think causes cloudy (white not dirty) water that comes out of the kitchen tap when on hot. It doesn’t do it on cold, and if you boil cold, you don’t get the same residue. The photo attached is the residue after 30 seconds when the water settles.”

Very simply in most cases, cloudy, hot water is caused by dissolved gases in the water. We assure you it is safe to use.

To get cloudy water from your hot tap, you have to create the right set of circumstances for everything to come together at the same time.

So why is my hot water cloudy?

To explain this a little more, you have to understand that all your water is stored in your water pipes under pressure. Therefore water under pressure has a higher capacity to hold dissolved gases. When water under pressure is heated the ability to hold those dissolved gases is reduced.

Primarily what happens then that is your cold water is heated in a water heater it creates hot water under pressure. This results in supersaturation occurring with dissolved gases. Ultimately those gases are released when you turn on the hot kitchen tap.

Another way to look at it is that when you turn the hot tap on you create that same kind of effect as when you pop the cork off a bottle of champagne because all that pressure has to go somewhere.

Why hot water is cloudy when you first turn on a tap?

The reason your water is milky or cloudy when you first turn the water tap on is that turning on the tap releases the pressure. This pressure release is often an initial highly pressurised burst. Because the dissolved gas comes out of the water in the form of tiny gas bubbles right throughout the water filling a glass or container. The gas bubbles then rise to the surface of the water and burst so that the water has a cloudy or milky appearance.

The cloudy, hot water will clear in a few seconds. As it is gas bubbles dissolving the water will clear from the bottom up. You can easily observe in a glass the water rapidly clearing from the bottom up.

The good news is that dissolved gas or air in water in reasonable quantities is not uncommon and means that the water is in a “healthy” condition.

We guarantee cloudy water does not mean you have defective hot water service or your water is contaminated. Generally, gas bubbles in your hot water supply will increase with the increase in temperature of your water because of the hotter your water, the lower the number of gas bubbles that can be held.

What should I do if my hot water is always cloudy?

If after the initial burst of hot water, your water is continually cloudy then it needs further investigation. Gas bubbles do not cause the cloudiness that does not dissolve in hot water.

Seldom is it a fault with your hot water service. If the water does not lose the cloudiness within thirty seconds, you likely have a water filtration problem or a sediment buildup in the hot water tank.
