Common Reasons for Sewer Odor Issues from Floor Drains

If the floor drain emits a bad odor, it can be quite unpleasant, and the causes may vary. Let me briefly introduce what causes the floor drain odor!

Causes of Floor Drain Odor

1. If you have purchased a traditional water-sealed floor drain, it is unlikely to effectively prevent odors. Even if the height of the water seal reaches 500 mm during installation, the height of the drain's water seal itself is only about 10 to 20 mm. Therefore, after some time of use, it is inevitable that the floor drain will start to emit odors.

2. If the floor drain is not tightly installed during the installation process, it can easily lead to odor issues.

3. If the drainage pipe remains in a dark and damp state for a long time, it can also cause the floor drain to emit odors due to environmental factors. Over time, the accumulation of waste in the pipes can lead to the growth of bacteria, resulting in unpleasant odors.

Precautions When Using Floor Drains

1. During the use of floor drains, it is important to regularly remove debris from inside the drain to maintain cleanliness and hygiene.

2. You can plug the drain opening with a rubber stopper to effectively prevent odors from escaping, or you can place a plastic bag filled with water over the drain opening.

3. After using the floor drain for a period, you may need to replace it based on its condition. If the odor prevention effect has been compromised, it is advisable to purchase a new type of floor drain, as newer models may offer better odor prevention.

Precautions for Using Bathrooms

1. It is advisable to install an exhaust fan in the bathroom, as this can help maintain ventilation. Proper airflow can reduce bacteria growth and minimize unpleasant smells in the bathroom.

2. When installing the toilet, ensure it is sealed properly. If the silicone seal around the toilet is damaged, it needs to be resealed. However, if you still experience odors, the toilet’s water seal might be compromised, and you may need to buy a new toilet.

3. The drainage pipes in the bathroom should be bent and sealed properly to effectively isolate odors coming from the wastewater pipes. For a more thorough solution, consider purchasing an odor trap for the sink.
