Why Is My Tap Water Foamy? (How To Fix)

Tap water already gets a bad rep when it comes to daily consumption.

People will often boil their drinking water and refuse to use what comes from the tap. This becomes an even greater concern when the tap water is foamy!

If the tap water is foamy, this means the aerator is creating pressure or a faulty plumbing fixture is causing air to push into the water. This is not dangerous, but it’s something you will want to fix. To correct the problem, shut off the water supply, remove the spout, and clean the faucet aerator underneath.

If you clean the faucet aerator, this should help remove some of the bubbles in your tap water.

This guide will take a look at why your tap water is foamy and what to do about it moving forward.

How To Fix Foamy Tap Water

1. Close Off The Water Supply

When you see white foam in tap water, it can be a point of concern.

The first thing you have to do is close off the water supply to the faucet. This will allow you to open up the faucet spout and see what’s going on underneath.

If you don’t do this, it’s likely the tap water is going to stay spraying everywhere.

It’s better to turn off the water supply using the water valve. Just ensure water is not going to the faucet. Once you do this, let the water drain out of the faucet by turning it on for a few minutes.

Once the water is drained, you can begin working on fixing the foamy tap water.

It’s important to take your time during this step to avoid water damage.

2. Remove The Faucet Spout

You are now going to remove the faucet spout.

Each spout is different but most are going to spin off easily. You will want to loosen the faucet to ensure you can get it off.

The faucet spout has to come all the way off for you to access the aerator underneath. This is the only way to ensure you can clean the aerator to stop foamy tap water from being an issue.

When doing this, make sure you are not damaging the external surface of the faucet. Do it carefully and only spin the top of the spout.

3. Brush The Aerator

You will now want to brush the aerator.

This will ensure you can access the reason for the foamy tap water. It’s common to see white foam when the tap is turned on.

This is an issue with the aerator in most cases.

Due to this, you will want to see if there is sediment in the aerator or other types of debris. This will ensure you know what the reason is for the problem.

In general, the best way to remove debris from an aerator is to use a brush. You can use a toothbrush to get in properly.

Do this thoroughly and make sure you scrub everything off before re-installing the aerator. If you don’t do this, it is going to continue to ruin the water and make it foamy.

Another option is to replace the faucet aerator if that is the route you wish to take but it is unnecessary.

4. Tighten the Spout

The last step is to tighten the faucet spout.

You will want to put everything back and then turn on the water. This will allow you to test whether or not the faucet is working the way it is engineered to.

It’s also important to see if there is foam in the tap water now.

If it is not working, this means the aerator has to be replaced. If you already replaced it, the main issue might have to do with where the water is coming from. This can include a loose plumbing fixture.

It’s best to consult with a plumber in a situation such as this.

Is Foamy Water Safe?

Foamy water is safe and can be consumed. The most common reason for foam in water has to do with a plumbing fixture being loose or improperly installed. A good example can be a faulty aerator in the faucet. To fix this issue, remove the faucet, clean the aerator, and re-test the water.

This should fix the problem and get rid of the foamy tap water.
