If the question of whether your tap water is distilled has ever occurred to you, then guess what? You’re not the only one. I’ve heard it asked in places like restaurants and classrooms.

So let’s get right to it, is sink tap water distilled water? The answer is no. Generally, the water that flows through your kitchen sink or bathroom tap is not distilled. That’s because the distillation process involves boiling water and then collecting the steam that comes from it. This is not how your sink tap water is treated.

Now let’s look at the differences between the two types of water in more detail.

Understanding The Differences Between Sink Water and Distilled Water

The key difference between tap water and distilled water is that tap water can contain impurities such as chlorine, lead, iron, and other minerals that can affect the taste and smell of the water.

On the other hand, distilled water does not contain these impurities because it has been specially processed to remove them.

So when comparing the two types of water, distilled water has a purer and cleaner taste.

In terms of safety, both distilled water and sink tap water is considered safe to drink since they are both regulated by various government agencies.

Usually, sink water contains trace amounts of minerals such as calcium and magnesium, as well as chlorine and other chemicals used by local water supply companies to treat the water. These minerals and chemicals are considered safe in small doses, as they also provide some essential minerals that are beneficial for human health.

Distilled Water Uses

Distilled water has a variety of uses beyond just drinking it.

  • It can be used in laboratories for experiments due to its purity.
  • It can also be used in steam irons to reduce mineral deposits.
  • It can also be used in baby formula since it does not contain any kind of contaminants that could potentially harm infants.

In many cases, people with contact lenses prefer using distilled water when cleaning their contact lenses because there is no risk of getting an infection from bacteria or other contaminants found in regular tap water.

Sink Tap Water Uses

While the primary use of sink tap water is for drinking, it can also be used in a variety of other ways.

  • It can be used to water plants, to clean fruits and vegetables.
  • It can also be used to make coffee and tea since it contains minerals that enhance the flavor of these beverages.
  • Finally, it can be used to fill aquariums if the proper filter is installed in order to remove any contaminants that may be present.

If you are unsure of the source of your sink tap water, it is always best to get it tested before using it for any purpose.

Does Boiling Water Make It Distilled?

The primary purpose of distilling water is to remove contaminants and other impurities that can be found in sink tap water.

So while boiling water can help reduce some of these contaminants, just boiling water does not distill them. That’s because the distillation process involves collecting the water vapor created when boiling, not just heating up water.

In order to distill water you would need a specialized distillation apparatus, which uses heat to evaporate the water and then condenses the steam back into a liquid that is free of contaminants in a separate chamber.

This is why true distilled water has a neutral pH balance (7) and does not contain any minerals or other elements that may be present in sink tap water.

So, to answer the question: no, boiling water does not make it distilled. But if you need truly pure water for drinking, distillation is the best way to ensure you get it. With that said though, many people also choose to use reverse osmosis systems for their drinking needs since they require less energy and cost less than distillation systems do.

Final Thoughts

So when it comes to it, there is a difference between sink tap and distilled water is its composition and uses.

Sink water is not distilled, but is typically safe to drink due to its regulation by government agencies. It contains minerals, chlorine, and other chemicals used for water treatment that can enhance the flavor of coffee, tea, and other drinks.

Distilled water is also safe to drink but does not contain any impurities as it is specially processed to remove them. It has a purer and cleaner taste and can be used for various things such as cleaning contact lenses, baby formula, and laboratory experiments.

It is typically more expensive than regular tap water though, so make sure to weigh the pros and cons when deciding which one to use for drinking.
