Why doesn t the water in the toilet or squat pit be full?

The working principle of the toilet bowl is the result of the comprehensive consideration of the original designer, who took into account the height of the trap and the suction of the water, as long as it is not clogged, it will not overflow. The squatting toilet has a lower trap and will not be full as long as it does not clog the water.

The water in the toilet or squatting pit will not be full because there is an inlet at the bottom, and there will be water in the inlet, so if there is water, he will keep a water volume, so that the water in the bend will be maintained. As soon as it came out, it was so much water.

Because the drainage pipe under the toilet bowl has a corner bend, the purpose of this corner bend is to let the toilet store water and prevent the odor from turning up from the pipe, when the water in the toilet reaches the amount of water designed by the corner bend, the excess water will flow out, so the water in the toilet will not be full. Hope to adopt.

will be full. The reason why it is not full is because the manure tanks are often cleaned, and there are many manure tanks that are connected to the sewer, so the toilets and squatting pits are not full.

If the manure tank is not connected to the sewer and is not cleaned in time, there will be a huge pressure in the manure tank, and the feces and feces will rush upwards, and if you are lucky, you will be sprayed sticky.

You can imagine that, according to the principle of connecting pipes, the water level at both ends of the U-shaped pipe should be of equal height, so the water level will be the same, unless, the water level is raised to exceed the highest point of the end turn, at this time, the B sewage will overflow and fall down the sewage pipe, which is why it is called a flush toilet. Let's follow the facts. When you are done and pull down the switch of the water tank, the water in the whole tank will pour down, the water level will increase, and it will be higher than the highest point, and the filth that has been strongly washed into by the water will be like falling into a cliff, and it will be gone forever!

However, when the water level has stabilized, there will still be a section of water left in the U-shaped pipe, which is why we see that there is always a small pool of water at the bottom of the toilet.

Because under normal circumstances, the cross-sectional space of the large pipe is not fully occupied, and the air is constantly ventilated up and down, so there is no pressure difference between the inside and outside of the toilet, and as far as I know, there is a ventilation pipe on each floor connected to the large pipe to prevent it from forming a pressure difference.

It's a strange question you asked, there is a mouth under the water in the toilet, so it won't be full. will flow out.

Why is the water in the toilet or squatting pit not full, of course, it can also be full, for example, the sewer is blocked, but in general, it will not be bought, because the principle of the connector is that most of the sewage goes down from here.

My personal guess is that there should be a one-way valve, and the water can only flow down and not up.

Because there are pipes, the pipes drain the water.

If there is too much water, it will overflow and run away from the drain.
