What is the reason why the toilet pours water and sprays water?

When flushing the toilet, the water in the toilet flows back from the sewage pipe in the opposite direction, splashing. This situation is very unsanitary, which may lead to the spread of bacteria and viruses, and also bring discomfort and stench to users. There are many reasons why the toilet pours water and sprays water. The following are several common reasons.

1. Pipeline blockage: Dirt or foreign matter in the pipeline may lead to pipeline blockage, resulting in poor drainage of the toilet, increased pressure, and water pouring and spraying.

2. No S-bend: S-bend is an important part to prevent sewage backflow and odor leakage. If the S-bend at the bottom of the toilet is improperly installed or blocked by objects, reverse water flow will be formed, and water spraying becomes possible.

3. Air duct blockage: The air duct of the toilet is generally in the wall. If the air duct is blocked, the discharged sewage will not flow out normally, which will also lead to water pouring and water spraying.

4. Defects in toilet design: Some toilets are unreasonable in design, and the outlet of the toilet is low, and there is not enough hydraulic power to push the sewage into the sewer, which is easy to cause the water to flow backwards.

5. waterless lock: the water lock is an elbow in the toilet, which can catch the water at the bottom and form a barrier to prevent sewage from flowing backwards. If the water lock is broken or loses its activity, it will cause water to flow backwards and splash.

6. High water pressure: When the water pressure is too high, the water in the toilet will flow backwards due to the reverse pressure. This situation usually occurs in large public buildings, hotels and other environments with high water pressure.

In order to prevent the toilet from pouring water and spraying water, we need to clean the pipes frequently, keep the water changing, don't litter, and regularly check all kinds of anti-dumping parts of the toilet. If water is poured or sprayed, you can try to dredge the toilet with a toilet dredge, or ask a professional to handle it.
