Comparing Deep and Shallow Water Seal Floor Drains: Key Differences Explained

The floor drain is mainly used in bathrooms to effectively reduce blockages and prevent backflow and odors. Next, let's introduce the differences between deep water seal floor drains and shallow water seal floor drains.

Differences between deep water seal floor drains and shallow water seal floor drains

1. Deep water seal floor drains have a built-in odor prevention device that extends into the drainage pipe, increasing the evaporation time of the water seal and enhancing its odor prevention capability. This ensures smooth drainage, and deep water seal floor drains have good odor prevention effects, but their drainage speed is slower.

2. Shallow water seal floor drains, lacking a water storage bend, can allow odors and pests to enter through the drainage pipe. They are prone to drying out, and if the drainage pressure is high, it can damage the shallow water seal floor drain.

How to remove and replace a floor drain

1. As the floor drain is an important interface connecting the drainage pipe and the indoor floor, and is a crucial component of the drainage system, it is essential to first determine the size of the floor drain before removal. If replacement is necessary, purchase a new floor drain that matches the size and shape of the old one.

2. Pay attention to the depth of the drainage pipe. Generally, the floor drain can be a T-shaped drain or a deep water seal drain. You can use a stick to test the depth of the drain, which is typically around 6 cm or 12 cm.

3. When removing the floor drain, use tools to chip away the cement at the junction between the floor drain and the floor tile, then use a hammer as needed.

4. At this point, you can easily take out the floor drain. Use a plastic bag or cloth to block the drainage hole to prevent debris from falling in and clean up the cement around the drain.

5. After removal, you can apply new cement putty around the floor drain area, also applying putty on the back of the new floor drain. Then, install the new floor drain into the drain pit and remove any excess putty, completing the removal and replacement of the floor drain.

In summary：this concludes the introduction of the differences between deep water seal floor drains and shallow water seal floor drains. I hope this information is helpful to everyone. For more related knowledge, feel free to check our website for updates.
