Preventing and Repairing Sewage Backup in Your Bathroom: Tips and Tricks

The floor drain in the bathroom serves an important drainage function. When there are drainage issues, it is essential to address them promptly. Below, I will introduce some methods to deal with foul water coming from the bathroom floor drain.

What to do if the bathroom floor drain emits foul water

1. First, insert the air pump's intake into the drainpipe of the floor drain, then block the floor drain. Continuously pump air to create pressure; this should help clear the blockage and allow it to drain into the sewage pipe.

2. You can mix a high concentration of vinegar with baking soda and pour it into the drain. Wait for some time for the reaction to occur, then continuously rinse the floor drain with clean water.

3. If you are unable to clear the blockage yourself, it is advisable to call a professional to handle the issue.

Precautions for installing a floor drain

1. Before installation, remove the drain core to prevent debris from entering it, which could affect its performance. If the bathroom’s drain pipe is located close, you can trim it to ensure that it is lower than the floor surface after installation, without damaging the waterproof layer during the process.

2. If the drainage pipe in your home is far above the floor, you can fill it with cement mortar to raise the pipe height, allowing it to be inserted into the drainage pipe. Before starting, be sure to block the drainage pipe with cloth to prevent debris from falling in. After filling with mortar, ensure it fully solidifies before connecting it to the drainage pipe, and the floor drain should fit tightly against the pipe wall.

3. Choose the right type of floor drain; for example, a washing machine requires a specialized drain. Also, make sure to consider the speed and volume of water flow in the drainage system. Using an incorrect type may lead to overflow onto the floor during drainage.

In summary：this is an overview of how to address foul water issues from bathroom floor drains. You can use the methods mentioned above for resolution, and remember to pay attention to details during the process.
