Closed water test steps:
1. After the waterproof construction is completed, the closed water test can be done after the waterproof layer is dry;
2. Temporarily block the floor drain and the perimeter of the pipeline mouth;
3. Build a 20 cm high retaining wall at the door;
4. Start to store water, with a depth of 5-20 cm, and mark the water level;
5. Water storage time 48 72 hours;
6. After the water is closed on the first day, see if the water level has dropped significantly, if so, please check whether there is leakage around the roof and pipes downstairs in time, if not, continue to close the water;
7. On the third day, the water is closed, and the downstairs ceiling and roof pipes are fully inspected.
8. Carry out the next process after being fully qualified.
Judging from the picture, the gap is not evenly balanced, and if you flick it with a tool from the corresponding direction, it should be aligned, and there will be no big gap, try it.
You don't care how many layers of leakage it has, even if you have 100 layers of leakage upstairs, then it must be that you must be leaking upstairs, why should you take the money to repair the upstairs, this is the problem of the property, not the problem of your owner, continue to find the property, let the property and the owner upstairs coordinate, the maintenance of the property is justified, you have paid the property fee.
