Under normal circumstances, the structure of toilet sewer communication is relatively sealed. When frequently used, the water flow is temporarily blocked, so that other substances in the tub can be easily washed away without causing the water flow to flow backwards or re-enter the water tank. However, once the sewer leaks, it may cause insufficient liquid pressure in the toilet, thus affecting the situation that water completely flows into the sewer. At this time, the water will stay in the toilet, which is easily affected by the external temperature. The freezing caused by the temperature drop will form snow in the toilet.
To avoid this situation, the most effective way is to keep the ventilation environment inside the toilet and ensure the tightness of the sewer. You can regularly check whether the sealing ring of the toilet sewer is damaged or loose, and pay attention to whether there is water leakage between the water tank and the toilet. If there is any situation, it can be handled in time to avoid the toilet from freezing. In addition, when using the toilet, we should also be careful not to throw toilet paper and other substances directly into the sewer to avoid blocking and loosening the sealing ring.
