How to Fix a Stuck Plastic Core in a Floor Drain: Tips and Solutions

After a long time of use, floor drains may inevitably get damaged and require replacement. If the plastic core in the floor drain cannot be unscrewed, here are some solutions.

What to Do if You Can't Unscrew the Plastic Core in the Floor Drain

1. You can apply some lubricating oil around the plastic core of the floor drain to provide sufficient lubrication between the core and surrounding parts, which may make it easier to unscrew the plastic core.

2. Another option is to spray some loosening agent around the plastic core. Once the core and surrounding components are loosened, you should be able to unscrew it.

3. If the above methods fail to move the plastic core, then it may be necessary to replace the entire floor drain with a new one.

How to Deal with Slow Water Drainage in the Floor Drain

1. There are many reasons why a floor drain may drain slowly. Different reasons will require different solutions. Therefore, when you notice slow drainage, it is essential to first identify the cause. Generally, slow drainage is often due to blockages in the drain outlet.

2. As floor drains are used over time, the drain outlet can frequently become clogged with hair, paper scraps, and other debris, resulting in slow drainage. It is advised to regularly check and maintain the drainage position of the floor drain to avoid blockage.

3. If you find that there is a significant amount of debris accumulated in the drain outlet, you should promptly clean it out and wash the outlet with water. If necessary, it is best to place a trash can near the floor drain to dispose of items that could cause clogs.

4. To effectively prevent blockages in the drain, it is recommended to ensure that the floor is installed with a certain slope during the installation of the floor drain. Insufficient slope will inevitably lead to blockages. Generally, creating a slight slope beneath the sink and toilet is sufficient.

In summary：the above is a detailed introduction on what to do if the plastic core in the floor drain can't be unscrewed and how to handle slow drainage. It is advisable to consult a professional if you are unable to unscrew the plastic core to avoid damaging the floor drain.
