Reason analysis: It may be that the height of the water seal of the floor drain is not enough, and it is easy to dry up, causing the odor in the drainage pipe to overflow into the room.
Solution: First, there may not be a water trap in the floor drain, just add one to it; second, replace it with a floor drain of the same brand and specifications. But during construction, be careful not to damage the waterproof layer. In addition, it should be reminded that in use, the water seal should be prevented from drying up, and water must be filled regularly. If you leave for a long time, it is best to seal the floor drain with a lid.
Analysis of the cause: It may be that the overflow section of the floor drain is not smooth enough, the sewage cannot pass through quickly, or the internal structure of the floor drain is convex and concave, which catches hair, fibers and other dirt.
Solution: The height of the floor drain is determined by the pipe arrangement of the drainage system. Therefore, the height of the floor drain used with it is best to be within 200mm and within 120mm, and it must be drained laterally. Commonly used methods of concealed installation are two types: partial sinking cloth pipes on the structural floor of the bathroom and cushion cloth pipes for the bathroom. In order to meet the requirements of toilet headroom and ergonomics, the sinking headroom of the former is 300mm, and the cushion height of the latter is up to 170mm.
Solution: Open the floor tiles around the floor drain, dig out the surrounding cement to a depth of 3cm, and then seal it with a "plugging agent". After 1 hour, do a closed water test to observe whether it is still seeping.
When decorating the house, sewer pipes will be reserved in places prone to water accumulation, and floor drains are generally required to be installed above the pipes, such as toilets and balconies. Generally, the installation area is mostly the place where water is easy to accumulate. First, it will be waterproof, then the floor, and finally the tile. The floor drain is pre-buried in the floor during the process of making the floor. If you want to be underwater quickly and without residue, it is required that the floor drain be the lowest point in the floor area, and it should be inclined, which is beneficial for draining water. The height of the floor drain is generally divided into sinking and flat. What kind of floor drain is good and how to choose a floor drain
