There are two possibilities for water seepage downstairs, one is the leakage of domestic water to the downstairs, and the other is caused by the leakage of the buried water pipe on the ground. You can use the pressure test to see if the pressure is lost to determine whether it is a leakage of the buried water pipe, or you can turn off all the water outlet valves to observe whether the water meter rotates and walks. If there is no problem with the buried water pipe, it is only that the waterproof layer is cracked, and the cracked position can be plugged with leakage.
1.Be sure to do wall waterproofing. Before laying wall tiles, do a good job of wall waterproofing. Generally, the wall should be waterproof with a height of 30 cm, but for non-load-bearing light walls, the whole wall should be waterproofed, at least 60 cm high. >>>More
