Ultimate Guide to Converting Floor Drains to Sewage Drains

To set up a drainage system in the bathroom, installing a floor drain is essential. If you want to change the floor drain into a drainage pipe, here’s how you can do it

Everything You Need to Know About Converting a Floor Drain to Sewage

1. If a floor drain is originally set up and you later want to change it into a drainage pipe, one method is to elevate the floor and install the drainage pipe, although this could affect the drainage issues.

2. Another, more complex method involves breaking through the floor slab to reconfigure the drainage pipes. However, this process is more complicated and requires work on the floor below.

3. Alternatively, you could directly modify the drainage pipe to function as a floor drain. After converting it into a slimmer type of floor drain, you can then connect it to the drainage pipe, ensuring it doesn’t interfere with drainage issues. However, if the water seal height is insufficient, it may lead to odor return. Therefore, it’s essential to keep the floor drain filled with water to prevent evaporation, or choose an internal floor drain that retains water, minimizing the risk of unpleasant odors.

4. Additionally, it’s important to ensure proper drainage facilities and maintain a certain slope on the floor. A slight incline can significantly aid drainage. Thus, to convert to a drainage pipe, adequate waterproofing and drainage measures must be implemented.

How to Convert One Floor Drain into Two in the Bathroom

1. If the bathroom has only one floor drain, adding another can improve drainage. When installing the new floor drain, it's important to ensure there's a separation between wet and dry areas, so both zones should have independent drainage that does not interfere with one another.

2. To add a floor drain in the dry area, first determine the location of the new floor drain, marking it in line with the existing one. Next, you will need to cut the floor surface carefully, avoiding any damage to the rebar. Once the drainage pipe associated with the original floor drain is successfully modified, clean the surrounding area and repaint it with waterproof material.

3. After allowing the waterproofing to dry, install the drainage pipe properly and secure it with cement mortar using a T-junction pipe fitting. This way, you can effectively convert one floor drain into two.
