1. The floor drain is blocked
In life, some debris, hair, paper scraps or garbage will flow into the floor drain with the water flow. As time goes by, the floor drain will be blocked, and the water will naturally become slower and slower. At this time, it is necessary to use caustic soda or dredging agent to dredge in time, so as to return to normal. In addition, it is recommended that you clean the floor drain regularly so that problems such as floor drain blockage will not occur.
2. Insufficient slope
When many owners build the bathroom, the slope is not well designed, resulting in the water not flowing smoothly into the floor drain, and there will be problems such as slow drainage. At this time, it is best to find a professional to redesign the slope, and control the slope to more than 1%, but not more than 2%, otherwise there will be a sense of inclination, so that the problem can be solved.
3. Construction waste residues
A lot of construction waste will be generated during home improvement. If the construction waste is not cleaned up during land reclamation and cleaning, it will cause the floor drain to drain slowly. At this time, it is necessary to open the floor drain cover and use tools to clean up the construction waste in the floor drain, so that it can return to normal. If you can't clean it yourself, it is recommended to find a professional to deal with it at home, so as not to cause major problems.
4. The water pipe is offset
In addition to the above three reasons, it may also be caused by the deviation of the downpipe. Because during home decoration, the sewer pipe will inevitably have a certain offset. For example, if the floor drain is not perpendicular to the sewer mouth, or if it is a little crooked, it will cause the caliber of the sewer pipe to become smaller, resulting in problems such as slow drainage of the floor drain. At this time, it is necessary to find a professional to redesign and adjust the position of the floor drain or the sewer pipe, so as to solve the problem fundamentally and thoroughly, without worrying that the floor drain or the sewer pipe will be blocked.
