What is the difference between siphon flush and gravity flush?

2022-12-14 14:34

Many people may not be aware that the toilets we use every day have their own differences. 

Depending on how they flush, toilets can be differentiated into gravity flush toilets flush and siphon, 

and if you don't know the difference, you may be at a loss when it comes to buying one. 

If you want to buy a toilet, it is necessary to know the difference between these two types. 

Also, the main need for a toilet is drainage. 

Which type of toilet has the best drainage capacity and how does it perform in terms of noise? 

If you have these questions, take a look at my analysis.

1) Difference


If you don't know the advantages and disadvantages of buying a toilet, 

you may have some problems that affect the quality of life of the whole family. 

The main difference between gravity flush toiletsand siphon toilets is that their pipe design is different, 

and the structure determines the operation, so the way they flush is also very different.

Gravity flush toilets do not use much water each time, 

mainly through the compressed air to generate thrust, 

push the water flow to flush away the dirt in the toilet, 

the impact of the water flow is more concentrated, so the drainage is faster.

The siphon toilet's drainage pipe is very different from the direct-flush type, 

its path is long and curved, it is a lying "S" shape, the drainage process is "tortuous", 

so the drainage is slower, mainly using the siphon principle, 

with a large amount of water to clean the wall of the bucket and the bottom of the dirty 

The main purpose is to use the siphoning principle to clean the walls and bottom of the drum with a large volume of water.


2) Sewage capacity

The pipes of the gravity flush toilet have a short path, a large diameter and are not curved, 

so some large dirt and debris can be easily handled, and it is not easy to have a "traffic jam", so it is less worrying. 

It requires less water flow, so there is not much standing water, which saves water. 

The short, straight design allows the water to concentrate its main "force" on the dirt at the bottom of the commode, 

which weakens the cleaning ability of the walls and affects the overall decontamination effect. In addition, 

it has no water storage bend and no odour control, leaving the washroom with an unpleasant odour, 

which affects the experience of using it.

Siphon toilets have a lot of suction and a relatively good drainage capacity. 

When flushing, the water flow swirls around the walls of the bucket a little, which cleans the walls better than a direct flush. 

The advantage is that it is a curved design so there is storage for water and it is less likely to waft out odours. 

However, it requires more water to create a siphon than a direct flush toilet, so it uses more water and is a bit water intensive. 

In addition, the long and narrow bend of the bowl makes it easy to block.

 It can handle human excrement and paper waste, but it is not so good at "digesting" food waste.


3) Noise

The gravity flush toilet has a short and fast flush, and the corresponding noise is also relatively loud, 

which can occasionally scare people in the dead of night. 

Some people don't like this kind of scare, especially children in the family, 

who may be afraid to go to the toilet by themselves in the middle of the night.

Siphonic toilets are not too loud when flushing, 

they are quite quiet and do not disturb the entertainment and rest of others when someone in the house is using them. 

If someone in the family is sensitive to noise, the siphon toilet is friendly.

After analysing these two types of toilets, it is easy to see that although they have their pros and cons, 

as long as you don't like dumping large debris into the toilet, 

a siphon toilet is still a much better experience than a straight flush toilet. 


So, do you have the answer to which toilet is more to your liking?
