Why Toilets in the US Are Filled Almost to the Top with Water: The Answer Will Surprise You
Any resident of the post-Soviet space, who finds himself in an American toilet for the first time, will first think that the toilet is clogged.
The thing is that in the US toilets are filled with water almost to the top. We explain why.
Why are toilets filled with water in the US?
As the Zen channel Home garden handmade reports, the drainage system in the USA is significantly different from ours.
It is called American Standard. The differences begin with the sewer system design.
Our drain pipe is located at floor level and goes into the wall through a pipeline.
In the US it goes into the floor between floors. Due to this, it is possible to use an ejector system in the US.
The flush occurs as follows: when you press the lever, the flush valve opens, and water begins to flow into the bowl from the holes under the rim of the toilet.
First the water level rises a little, then it is pushed into the pipes under pressure.
When all the water is drained, an airlock is formed in the pipe. The flush stops and water begins to fill the bowl and tank (if any).
It is difficult to say how many advantages such a system has. But there is definitely one noticeable disadvantage: flushing is very loud.
