Why Does the Floor Drain on the First Floor Backflow?

Floor drains are mainly installed in kitchens, bathrooms, and balconies, which are areas with significant usage of water. They are essential drainage components. So, how do you modify a bathroom to add a floor drain? How do you select a suitable floor drain?

How to Modify a Bathroom to Add a Floor Drain

One way to add a floor drain is by raising the bathroom floor to rearrange the drain pipes. However, this installation method may affect drainage, potentially leading to blockages or leaks. Another method involves breaking through the existing floor slab and re-routing the drain pipes to add a floor drain. This approach can be quite troublesome, as it requires addressing the issues with your own bathroom floor as well as coordinating with the neighbors below.

For bathrooms that are already renovated, adding a floor drain later can be very complicated, so it is essential to plan this before renovation. If it is necessary to add one after the renovation, you can consider removing the tiles beneath the sink and changing the connection to a larger size if it doesn’t affect drainage. If it does affect drainage, it is advisable not to force the installation to avoid unnecessary complications.

How to Select a Suitable Floor Drain

1. Determine the intended use of the floor drain. For instance, if it is for a washing machine, it should have a circular opening in the middle to allow the drainage pipe to be inserted.

2. Pay attention to the brand of the floor drain. It is best to choose well-reviewed and reputable local brands and avoid unknown, unbranded products, as their quality cannot be guaranteed.

3. Ensure that the floor drain has an odor prevention device. Without such a device, the bathroom is likely to have unpleasant odors, especially in humid weather.

How to Prevent Bathroom Floor Drain Clogs

To avoid clogs in the bathroom floor drain, you can take a pair of women’s stockings, cut them, and use them to cover the drain. The stockings allow water to pass through without affecting normal drainage while effectively trapping fallen hair and other debris, thereby preventing clogs.
