How Does a Kitchen Faucet Work? (All You Need to Know)

A kitchen faucet is the most used element in a kitchen. Without the active participation of faucets, you cannot do any work properly.

People do not usually think about how does a kitchen faucet actually work? It should be essential for anyone who is working in the kitchen.

All the faucets are similar in function but not the same. Also, the internal mechanisms of faucets vary from model to model.

If you don’t know about the inner mechanisms, then you might get into trouble while facing any problem with the faucet. So, let us discover how a faucet actually works.

How does a kitchen Faucet Work?

A kitchen faucet works in a very sophisticated way. When a person rotates the handle of a faucet, the cartridge opens up the ways so that the water can travel through the valves and sprout. Then, due to the aerator, the water comes out of the nozzle at standard pressure.

A kitchen faucet actually works with the help of different parts. If you know about all of them, you can easily dissect how it works. Now, we will explore how the different parts of a faucet function to make it work.


This part is very important as it helps to open or close the cartridge, and eventually, you get the water. Nowadays, you will typically find single-handled faucets. Handle/s sit/s just at the top of a sprout. So, when you need water, just rotate the handle.

Cartridge/ valves:

Cartridge is the major component of a kitchen faucet. These are also known as cartridge valves which you will find in the form of a small cylinder. Cartridges are normally made out of plastic or brass.

These are directly connected to the handles. When you press the handle, this small cylinder ensures that the water is traveling from different channels successfully. The cartridge also helps to maintain water temperature and pressure.


The body is the place where the hot and cold water gets mixed.  If you have a single-handled faucet, then water will come to the body from a single pipe. This is the process found in most faucets nowadays.


Sprout is the path from which water travels from the faucet body to the sink. Sprout is the first thing that people see when they look at a kitchen sink. These are found in different shapes. For example, gooseneck, high-arch, shepherd’s crook.


This part sits at the tip of the kitchen faucet. It is usually made out of mesh. The main work of an aerator is that it helps to reduce the faucet water pressure and maintain a balanced output. With an aerator at work, you will never have wastage of water.


These are the place from which the water comes out of the sink. Some sinks have nozzles that can filter the water, and some nozzles don’t.


This one is a handy tool that resides at the side of your faucet. A faucet sprayer actually helps you to clean places which are hard to reach. This thing is made out of three different parts- a hose, a nozzle, and a diverter valve.

Inside the faucet, you will find a diverter valve. When you press on the trigger or the handle of the sprayer, the water will easily come out of the nozzle from the hose by traveling through the hose.

These are all the parts through which a faucet functions. If any one of these is somehow damaged or not working, then surely there will be leakage.

If you face any problem with your faucet, then call a professional as soon as possible. Or it might cost you some extra pennies later on.

Step by step process : How does a faucet work?

Step 1:  Whenever you are rotating the handle of a faucet, the cartridge or valve, which are directly connected with the handle, opens up all the ways for the water to travel properly to the body.

Step 2: Then, the hot and the cold water get mixed.

Step 3: If the temperature of the water becomes too hot, the cartridge will immediately turn off the supply of hot water and increase the pressure of cold water.

Step 4: Then, with the help of the sprout, the water will travel from the faucet body to the sink and come out of the nozzle.

Step 5: When the water is coming out from the nozzle, you will get standard water pressure because of their aerator.

Step 6: If you have a sprayer, then when you will press the trigger, the water will travel from the hose and come out of the nozzle.

Now you clearly how a faucet actually works.
