    If there is a peculiar smell in the bathroom, you have to check it one by one:

    1. Wash basin and floor drain drain:

    Do you first see if the wash basin and floor drain are being used incorrectly?

    1. The washbasin and the drain pipe of the floor drain in the bathroom of the general house have been distributed and installed, and the drain pipe of the floor drain must be equipped with a reverse bend, which can store a certain amount of water and prevent the smell from flowing back into the bathroom (see the yellow circle in the figure), this anti-bend should not be seen at home, and it can usually be seen on the roof of the bathroom downstairs;

    2. The developer of the drain pipe of the washbasin will sometimes set it without a backwater bend (see the red circle in the figure), which means that you need to set up a backwater bend under your own washbasin, if you use this sewer pipe without a backwater bend as a floor drain, the smell will definitely be reflected in the bathroom.

    In addition, if some floor drains are not used for a long time, the water in the bend will dry up, and there will be a peculiar smell.

    Second, if the ventilation duct of your bathroom is not directly discharged outside the hole in the outer wall, but the public flue used, you need to check the cover plate of the check valve at the flue mouth, this cover is one-way open, and can only be opened from the bathroom to the direction of the inside of the flue to facilitate exhaust. If the cover is reversed, or the movable cover is stuck, or even if the reverse cover is not installed, there will definitely be odors.

    3. Whether the toilet is installed accurately:

    If the toilet and drain are misaligned, odors will return.

    Check it step by step, and good luck
