After buying a house and moving in, the bathroom has a bad smell, who is to blame

Possible situation: 1. The PVC pipe does not reach the ground, and the dirty water seeps into the base cement. This situation exists, but it is not a matter of floor drain, it is the drain of the toilet in addition to the problem, the water in the floor drain can only be dirty for a few days to emit a foul smell, and the smell of the basic bathroom is the smell of ammonia from the toilet. Workaround:

Remove the toilet bowl and drain the toilet bowl and then treat it with the plugging king (high-efficiency plugging cement).

2. There is no water in the anti-odor bend. The anti-odor bend of the water means that there is water in it to prevent odor, the new house has not been used, there is no water in the anti-odor bend, and the smell cannot be closed.

3. There is a problem with the floor drain. It probably means that the anti-odor is not good, and now it is basically a water-sealed floor drain, which means that there is no water inside, and the natural closure is not good, and the solution is to use it.

4. Carefully check the floor drain and other equipment, in short, if they are all tightly closed, this situation can be avoided.

5. The toilet is blocked. There are a lot of dirty things blocked in the anti-odor elbow of the toilet, and the toilet bowl that is generally not blocked is flushed, and the elbow is relatively clean water, which is very small, if it is blocked, how to flush it in the elbow is not clean, it has always smelled.

If there is this smell after decoration, it means that the decoration has not done a good job of waterproofing and deodorization, or the upstairs has not done a good job of leakage prevention measures.
