Why is My Tap Water Foamy?

Water is a necessity needed for life. It has several uses in our daily life. But what is its source, how does it get into your house, and where is it stored? There are various issues with tap water,  a factor that has been attributed to its negative stigma around it to some extent; some people don’t drink tap water.

Why is My Tap Water Foamy?

The dispensing spout is designed to inject air into the water, causing the aerated water from the tap to foamy, but it is not sudsy. The water in the pipes contains more pressure compared to the glass water.

Therefore, when water is quickly forced through pipes, it gets mixed up faster, triggering the water to mix with air to form bubbles. It is clear that when air is forced into the water, it aerates it to a point where the bubble becomes very small, looking like foam.

Foamy water is safe for use and even drinking without posing any danger to you. As we see in the next section, the issue is easily resolved by buying a new faucet or upgrading the old one.

How to Fix Foamy Tap Water?

It is a great concern to see white foam in tap water. Many people often boil their drinking water and not the direct tap water.

Knowing the cause of foam in tap water is out of the pressure from the aerator or a faulty plumbing fixture that needs to be fixed. To achieve the solution, follow the below steps:

Close Off The Water Supply

Cut off the water supply to the tap to allow you to open up the faucet spout and examine its underneath and also to prevent water from splashing all over the house.

It is more important to turn off the water supply using a valve.

Next, let the remaining water drain out of the faucet by turning it on once more for a few minutes.

After which, you can now start working on fixing the foamy tap. Spend quite a good amount of time at this step to avoid water damage.

Remove the Faucet Spout

At this stage, the faucet spout is removed. Each tap is different, but many faucets spin off easily. 

Loosen the faucet to ensure you get it off entirely to access the aerator underneath. You’re guaranteed to fully clean the aerator to eliminate the issue of getting foamy water from your tap.

Keep an eye on the external surface of the faucet to make sure it doesn’t get damaged.

Brush the Aerator

The aerator resembles a little mesh ring covering the exit to the faucet spout.

It is common to see the white foam when the tap is on but what you didn’t know is the aerator is the reason for the foamy tap water.

Examine the aerator for any sediment and other forms of debris for you to understand the reason behind the problem.

The best way to remove the debris from an aerator is to use a brush, and in this case, a toothbrush does a wonderful job. Do it thoroughly to ensure everything is scrubbed off by re-installing the aerator.

Additionally, you can replace the faucet aerator with a new one, although it is not a must.

Tighten the Spout

It is the final step –tightening the faucet spout.

Install everything back, and after that, turn on the water to confirm whether it is functioning properly or not.

It is paramount to check whether there is still foam in the tap water.

If it is not working, then you need to replace the aerator. If you replaced it, the primary issue might be the water source. Under the circumstances, you need to consult with an expert.


What is Tap Water and Its Source?

Water supplied through a tap, a water dispenser valve is referred to as Tap Water (Faucet water, Running water, or Municipal water).

Tap water is regularly used for drinking, cooking, laundry and lavatory flushing. It is usually distributed within the house through “indoor plumbing”. Faucet water comes from three major sources-lakes, rivers and groundwater. But this depends on where you are located because of the variance in water sources. An alternative to Tap Water is spring water.
