Toilet matters: how the American toilet works

Everyone knows that the life of Americans and Russians is radically different. But did you pay attention to the fact that even the principle of the toilet in the United States is not the same as in the post-Soviet countries? Details are told by Andrey Ratnikov at Yandex Zen. Next - from the first person.
On the Internet, you can find many stories of the same type from domestic tourists who have visited America. They tell us that toilets in the United States have a completely different design than in Russia or other European countries. American toilets are constantly filled with water, and there is supposedly never a brush we are used to.
I will disappoint you: there are no fewer toilet brushes in America than in Russia. In private houses and apartments of Americans, brushes are present in the same place as in ours - next to the toilet.
But in public toilets, they do not store the brushes next to the toilet, but in the closet or locker of the cleaners along with other cleaning equipment, and it is not so often that brushes are needed if there is water in the toilet bowl and a sufficiently intensive flush system.

It is generally accepted that the bowl of water was invented specifically to make the toilet less likely to get dirty. Since the first mass-produced toilets at the beginning of the last century had practically no problems with the quality of the flush. These were bowl-shaped toilets with high-positioned cisterns and a flush handle on a chain.
By the way, there were no problems with splashes when flushing in dish-shaped toilets. The anti-splash function was successfully performed by the toilet shelf (dish), the water level in which was 1-1,5 centimeters.
Modern toilets are conventionally divided into American (with an American flush system) and European (with a European flush system). The fact is that the Americans traditionally place sewer pipes under or in the ceilings of premises, while we and the Europeans - above the ceilings.
In Russian and European toilets, the drainage pipe is practically at the same level as the outlet of the toilet. A small amount of water in the so-called siphon of the toilet only serves to create a water seal that prevents sewer gases from entering the room. During the flushing of water in such a toilet, its contents are simply drained into the pipe without the siphoning effect of the drain inherent in American toilets.

In engineering, a siphon (from ancient Greek σίφων “tube; pump”) is usually called a curved tube with elbows of different lengths, through which liquid flows from a vessel with a higher level to a vessel with a lower liquid level. For the siphon to function properly, it is necessary to first fill with liquid (charge the siphon).
The location of the drainage pipes above the ceiling and the dry toilet bowl do not leave sufficient height for organizing a siphon drain in European toilet bowls.
But with the American method of laying pipes and a toilet bowl half-filled with water, it is quite possible to perform a siphon drain.
