After the toilet water storage test, the wall is wet and waterproof, and there is a problem

The bathroom does a closed water test, and the standard practice is as follows:

1. After the waterproof construction is completed, you can do the closed water test after the waterproof layer is completely dry;

2. Temporarily block the floor drain and the perimeter of the pipeline mouth;

3. Build a 20CM high retaining wall at the door;

4. Start to store water, with a depth of 5-20 cm, and mark the water level;

5. The water storage time is 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.

Therefore, to determine whether there is a water leakage problem in the bathroom, the main reference index is whether the water level has dropped significantly, and whether there are water stains or water leakage on the ceiling downstairs, rather than whether there are water stains on the wall and the situation in Chaohu City.

After the bathroom is waterproofed, in the water storage test, the water has nowhere to go, so it can only seep into the wall, which is very normal.

It is strongly recommended that the wall of the bathroom should also be waterproof, otherwise the other side of the bathroom wall will become moldy after a long time.
