In his life as a plumber, he installed and repaired more than one toilet bowl. In this case, as they say "I ate the dog" But recently, for the sake of curiosity, I began to be interested in how they are, in America, in particular in the United States. If you ask this question in the all-knowing web, in Russian, there is scant information about the principles of the "siphon" work of the toilet bowl. I also drew attention to the strange tank in the toilet cisterns of overseas comrades.
And it turns out I, and many Internet readers, are deeply mistaken. Only the "Siphon" principle of operation has long been outdated. Increasingly, they use supplementation. About which the overseas comrade told me. From whom I consulted to convey useful information to my readers. Now I will tell you what the "new" principle of work is.
How does the flushing of our toilets work?
The principle of operation is based on draining a certain amount of liquid from the tank into the toilet bowl. The water being under normal atmospheric pressure, accelerating from the elevation difference, washes the working area of the "white friend" And the higher the tank, the higher the efficiency. For reliable cleaning from waste products, approximately 8 - 10 liters of water are required.
The work of American toilets in the outdated version
Toilets in the USA, at their core, have a water outlet directly into the floor, interfloor overlap. Due to this, they have the opportunity to lay the siphon principle of operation of the "pots", by the way, I borrowed the new name of the toilet bowls from an American comrade:
A curved tube with different lengths of elbows that carries fluid from a vessel with a higher level to a vessel with a lower level of fluid. To ensure operability, the siphon must first be filled with liquid https://ru.wikipedia.org/wiki/
Or the explanation is simpler - most likely many had to pump gasoline from the tank, especially when they were young, to refuel their motorcycles. Sucking air from the hose with a tube, due to the difference in fluid heights, an automatic drain occurs. At the bottom of the tube, the liquid flows out, and a vacuum is created at the top of the tube, which sucks in the liquid.
Here is the same: "American" user washes his "result". Thus, it washes the bowl, as in our toilet bowls. And then the liquid, pumping through the bends, turns on the principle of a siphon. The water at the bottom draws water from the top, thereby creating a vacuum. Waste products are sucked in.
I knew about this principle of work. And in order to understand what kind of tank it is inserted into an ordinary toilet cistern, I turned to an American comrade in the pictures I found. In the correspondence, he explained everything to me in detail. What works and how. There is no information on this principle of work on the RuNet. Thanks to our comrade, we learn new, useful information:
How American Pressurized Toilet Bowls Work
It seems that nothing new can be invented in the field of toilets, but no, they have invented it. In order to effectively remove human waste products, a certain amount of water is required. This resource is in the west, and in our country it is constantly growing in price. Well, its cost is prohibitively high in comparison with ours. And so there they came up with, implemented a new, effective flush system. Using the minimum amount of water.
Their "pots" in appearance resemble our toilet bowls, but they embody completely different principles of work. First, the tank has a special design. Pressurized water is driven into it from the main line.
In the diagram above, you can see how it works. This container contains an air "cushion" that gains kinetic energy from the pressure of the rising fluid. As soon as the pressure in the tank is equalized with the pressure in the water supply. Fluid consumption stops. What happened? The tank has stored water, and compressed air has energy ...
The next step is to move on to the design of the American "pot". Unlike other outdated ones, it has a water outlet, right at the bottom of the toilet. Here is a photo from Maxim, an American plumber:
When an American citizen has completed all the chores in the toilet, he presses the button. Then the water in the tank does not just drain, but shoots out under high pressure from the "nozzle":
Due to this, the liquid at the bottom is drawn by the jet, the effect is observed ejection.
The ejection effect is that a higher pressure flow moving at a high speed entrains the low pressure medium with it. The entrained stream is called ejected.

Next, the siphon effect turns on, thereby sucking everything out of the toilet.
The advantage of this toilet bowl:
The most high water savings compared to conventional toilets. Improved removal waste products due to the accelerated flow of liquid. Pipeline less clogging, as there is a forced pushing of the "slurry". The toilet tank does not "sweat". The water is in a pressurized insulated tank. And the porcelain tank does not experience temperature changes. Which is important in high humidity and hot climates.
Cons of such a "pot"
- Loud flushing sound. It is recommended to close the lid before draining.
- A more complex toilet bowl design that requires special knowledge.
