2. Sewer odor: If it is an ordinary sewer odor, a metal net can be added to the water pipe above to play a filtering role, such as filtering out solid residues such as vegetable leaves; The position of the sewer mouth is covered with a net bag. It should be noted that the bag must be fixed and not blocked by the large flow of water rushing into the sewer.
3. Toilet odor: If the toilet is not tightly sealed and the structure is unreasonable, there will be odor. If the toilet seat sealing ring is aging and often leaks water, it will smell after a long time. It is suggested that the toilet be replaced and reinstalled in time.
4. Toilet floor drain: In the past, the bathroom design at home was reversed, and the bathroom floor drain was also reversed, which could be deodorized by water seal. However, in order to save costs, many communities have cancelled waterproof bends and adopted new floor drains to ensure that they do not stink. But in essence, it is a floor drain with unqualified quality, and the water seal of the floor drain is very shallow, which can't isolate the odor of the sewer pipe, so it leads to the odor phenomenon in the bathroom. It is suggested to replace the odor-resistant floor drain, which can effectively prevent the generation of odor.
5. Poor sealing of water pipes: Bad smell often occurs in the sewer pipes of sinks. This is because the joint between the sewer pipe of the sink and the sewer is not well sealed, so the smell will flow out along the gap. It is suggested to find a worker to seal the gap at the joint with glass glue or other adhesive, so that the gas can not be discharged. In addition, some water pipes are bent backwards with hoses. After a long time, the hoses will straighten and the smell will come out more easily. Therefore, it is recommended to replace the hose with a professional reverse hose.
