We can all agree that, when it comes to household fixtures, toilets are among the most important ones. Billions of people around the world use a toilet at least once a day. However, if you are not a professional plumber and have experience working with toilets, you probably don’t know how a toilet flush works.
How Does A Toilet Work?
In order to understand how an average toilet works, you need to know what a toilet consists of. Although there are a lot of toilets with different designs that use different technologies, most of them consist of two main parts – the bowl and the tank.
The Toilet Tank
First things first, you need to understand that a toilet tank works literally as a bucket, filled with water, being dumped into the toilet bowl. However, the toilet tank is way more precise and can accurately fill back up. Even though a toilet tank consists of a lot of different parts, they are all quite simple.
Flushing begins when you push the handle on the toilet tank. Once the handle has been pushed, it lifts the lever attached to a chain. The chain the lever is attached to is also connected to a flapper on the other end. This rubber flapper is located at the bottom of the water tank and its main purpose is to form a seal between the bowl and the water tank. Therefore, when you push the handle, it lifts up the flapper, allowing the water to flow inside the bowl, creating a flush.
Once all the water flows out of the tank, the flapper goes back to its place, creating a seal. After that, the fill valve starts bringing more water into the tank. When the float gets back to the determined level, the fill valve stops filling the tank.
The Toilet Bowl
The bowl is definitely the most essential part. The design and the shape of a toilet bowl allow for simple and effective waste removal. Now, the part of the toilet bowl that is crucial for effective flushing is the siphon. The way siphons work is by moving the waste upwards from the toilet bowl and creating a vacuum. The created vacuum then drags the waste down the pipe.
Therefore, even if something happens to your water tank, the toilet will still function properly. Pouring a cup of water into the bowl is less likely to cause the toilet to flush. However, if you poured a gallon or two into the bowl, the siphon would create a vacuum, causing the toilet to flush.
For those seeking alternatives to standard toilets, exploring options like portable toilets, such as those available from Viking Rental, can provide valuable insights into more flexible sanitation solutions.
Different Types Of Flushing Technologies
Even though most toilets operate in a very similar way, there are different types of technologies you need to know about when buying a new toilet. Therefore, we are going to start off with the most popular and the most common one- the gravity flush.

Gravity Flushing System
The main reason why gravity flush systems are so popular nowadays is that they utilize the natural force of gravity to flush. With these systems, water flows from the water tank into the toilet bowl via gravity. Once the bowl is filled with water and the pressure inside it is bigger than the pressure in the drainpipe, the toilet flushes.
Pressure-Assisted Flushing System
The pressure-assisted systems, on the other hand, use gravity combined with compressed air. This way, the flushes are way more powerful than the ones on the gravity-only systems. Unlike the gravity systems, these have a mini plastic tank inside the main water tank. This mini tank is also called a pressure vessel.
Inside the pressure vessel is where the water mixes with the air. Therefore, when you flush the toilet, the water starts flowing forcefully into the bowl and creates a very powerful flush. However, keep in mind that these systems are mostly louder than the gravity ones.
Dual Flush System
If you are looking for a powerful, reliable and yet, water-efficient flushing system, aim for toilets with dual flush technology. This type of technology is also quite simple and allows you to choose between the partial and the full flush. Most of the time the partial flush consumes way less water and is meant to be used for liquid waste only. When it comes to the buttons, they are, most of the time mounted on the top of the water tank.
Double Cyclone Flushing System
This flushing system was designed by the TOTO company and is used in almost all of the TOTO toilets. On double cyclone flushing systems, there are two nozzles positioned on the top of the toilet bowl. They are facing sideways and thus, the water swirls inside the bowl and effectively removes all the waste.
A Few Words In The End
As you can see, toilet mechanisms are quite simple to understand. However, it is quite important to know how a standard toilet operates as it will be easier to locate and fix a problem once it occurs. Also, keep in mind that some of the parts will wear off over time. Still, most of them are quite cheap and simple to replace.
