What if the toilet is blocked? What is the reason for the blockage?

1, the toilet is slightly blocked: usually toilet paper or sanitary towel, towel rag, etc. , can use pipe dredge or simple dredging tools to dredge directly.

2. The toilet is blocked by hard objects: when used, it accidentally falls into hard objects such as plastic brushes, bottle caps, soaps and combs. This kind of blockage can be directly dredged by pipeline dredge or simple dredge. In severe cases, the toilet must be disassembled and dredged. This situation can only be completely solved by getting things out.

3, toilet aging blockage: the toilet is used for a long time, and the inner wall will inevitably scale. In severe cases, it will block the air outlet of the toilet, resulting in slow water intake of the toilet. The solution is: find the vent, scrape off the dirt and let the toilet go smoothly.

4, toilet installation error: generally divided into: the bottom outlet is not aligned with the drain, the bottom screw hole of the toilet is completely sealed, which will cause the toilet water to block, and the water level of the toilet tank is not high enough to affect the flushing effect.

5, squatting to the bathroom: some old houses have installed squatting pits, and the bottom of the sewer pipe uses a U-shaped waterproof elbow. When rebuilding the toilet, it is best to change the bottom elbow into a straight bend. If it can't be replaced, before installing the toilet, you must do a good job of cleaning the bottom of the toilet, and don't let cement or ceramic tile fragments fall in when installing it.

The reasons for the toilet blockage are as follows:

1. Hair causes sewer blockage: After the sewer is used for a period of time, the hair that is usually bathed will hang on the pipe wall, and excessive accumulation will cause blockage. Hair will generally cause toilet floor drain blockage, washbasin blockage, bathtub blockage and shower room blockage.

Therefore, when you use it at ordinary times, you must cover the floor drain cover and other protective facilities. If you have hair, you can pick it up and throw it in the trash can. Too much hair blocks the sewer: you can dredge the sewer by hand, and if it is serious, you have to dredge it by pipe.

2, hard objects blocking the sewer: it is also very common to accidentally fall into hard objects to block the sewer when using. Some people leave the cover of the floor drain open, so that some small things will fall in.

Extended data:

In addition, the toilet tank used in residents' toilets is filled with water. When water supply is stopped or users concentrate a lot of water, the pressure in the tap water pipe drops. At this time, if the water injection valve in the toilet tank is damaged or the rubber ring at the water inlet is not tightly sealed, blue water will flow back into the tap water pipe.

This only happens occasionally. Under normal circumstances, the water in the toilet tank will not flow into the water supply pipe. If you are worried about the backflow of the toilet water tank at home, you can change the water inlet mode of the water tank to the upper water inlet;

If it is found that the tap water discharged from home is blue, it can be discharged by discharging water. Under normal circumstances, the amount of water in the toilet tank is not very large, and it can be used after the color of the water is restored to normal by discharging water.

The water used for flushing toilets in some communities is "reclaimed water" (that is, non-drinking water that has been treated by urban sewage or domestic sewage to reach a certain water quality standard and reused in a certain range), which is separated from the tap water pipeline, so there is no possibility that the toilet tank of such families will pollute drinking water due to sewage backflow, so there is no need to worry.
