What should I do if the floor drain leaks downstairs?

1. The leak in the bathroom can be tested first, which is usually caused by the imperfect concrete and improper waterproofing of the floor drain pipe.

4. The floor drain pipe and the floor groove are embedded with sealing paste, and a new waterproof additional layer is constructed on the repaired base surface. The additional waterproof layer needs to be lined with grid cloth, the overlapping width of the grid cloth plane is 150mm, and the inner return width of the floor drain should be 30-50mm. Paint a waterproof layer compatible with the original waterproof layer to ensure that the new waterproof layer is The overlapping width of the original waterproof layer is 150mm, and the overlapping part of the original waterproof layer should be clean and dust-free;

5. When the main parts and waterproof are arranged, the surrounding impurities should be removed. After doing this, you must remember to conduct a water storage test on the floor drain, seal the floor drain, store the water for 24 hours, and observe carefully. Only when there is no leakage can it be regarded as qualified.
