What to do if the toilet smells musty

The odor in the bathroom mainly comes from the following places:

1. Floor drain back smell: The floor drain drain in the bathroom should have a reverse water bend, and the water is usually sealed to prevent the odor. At present, in order to increase the floor height and reduce the cost, many new residential areas have canceled the anti-drain under the floor drain, but adopted a new type of anti-odor floor drain to ensure that the sewer odor does not escape.

These odor-proof floor drains are often made of PVC materials, far less beautiful than the stainless steel and copper floor drains sold on the market, and many owners have replaced the floor drains that look beautiful and the actual quality is unqualified when decorating, resulting in bathroom odors, and it is recommended to use odor-proof floor drains.

2. Sealed sewer pipe odor: The connection between the sewer pipe and the sewer pipe of the sink is not strictly sealed, which becomes the channel for the sewer odor to enter the room. Since the sewer interface is in a relatively hidden place, it is easy to ignore it when the decoration is completed and accepted, and it should attract the attention of the owner.

You can ask the renovation worker to seal the gap at the interface with glass glue or other adhesive so that the gas cannot be discharged.

3. Toilet aftertaste: The structure of the toilet is unreasonable, and the water seal is not strict, which will cause the backsmell of the sewage pipe, or the sewage pipe is misplaced during the installation of the toilet, the aging of the base sealing ring or the poor sealing of the base, which will lead to aftertaste and even leakage of sewage, so it is best to reinstall.

Re-treat the mildew area with mildew-proof and waterproof materials, ventilate and dry, and there is no other way.
