The Hidden Reasons Behind Odors Coming from Floor Drains: Expert Insights

The floor drain is an important hardware component in the bathroom. If its quality is poor, it can easily lead to blockages. What causes odors to rise from the floor drain? What should be noted during the installation of the floor drain? Let’s take a look!

Causes of odors rising from the floor drain

1. Over time, the odor-proof function of the floor drain may fail. For example, in water-seal floor drains, the water seal can dry up or become blocked by hair and other debris. It is recommended to regularly clean the floor drain.

2. Improper installation of the floor drain may create gaps between the floor drain and the connecting pipe, allowing odors to escape. It is advisable to seal these gaps with materials like silicone.

3. Poor odor-proofing of the floor drain can lead to unpleasant smells circulating indoors. It is recommended to choose floor drains with good odor-proofing performance.

Preventing odors from the floor drain

1. Change the floor drain pipe to a curved shape so that odors cannot rise directly. This can help eliminate unpleasant smells. If you cannot make changes, consider adding an anti-odor drain core.

2. Regularly remove debris from the floor drain opening to keep drainage unobstructed and prevent odors from developing.

3. Frequently rinse the floor drain to prevent stagnant wastewater and sewage from becoming foul-smelling in the pipes.

What to note during floor drain installation

1. First, when installing the floor drain, block the drain pipe opening with cloth or other materials. Remove the blockage only after the floor drain is installed to prevent debris from falling into the drainpipe and causing blockages later.

2. After installing the floor drain, test its drainage function. Wait until the drainage is smooth before sealing the drain outlet with tape to proceed with tiling.

3. Lastly, be mindful of the installation height. The floor drain should be lower than the floor for better drainage. If the drainage pipe is too close to the ground, you can shorten the pipe so that the floor drain is below the floor level. Additionally, since various debris may accumulate during installation, it is best to remove the strainer beforehand to avoid damage from foreign objects.
