Do You Need to Reseal When Replacing a Floor Drain?

The floor drain is something that every household will install during renovation. Over time, you may want to replace it with a new one. So, does replacing a floor drain require redoing the waterproofing? Let's take a look together.

Does replacing a floor drain require redoing the waterproofing?

There are two scenarios. The first scenario is when you replace just the floor drain core without changing the casing; in this case, you do not need to redo the waterproofing, and you can simply carry out the replacement normally. The second scenario is when you replace the entire floor drain. For this case, it is essential to do local waterproofing around the new floor drain to ensure that the new waterproof layer covers the old waterproof layer.

Precautions for replacing a floor drain

1. Before installing the floor drain, first remove the floor drain core to prevent debris from falling in and causing damage. The main purpose of the floor drain is to facilitate drainage, so the position of the drain must be lower than the ground. If the drainage pipe is too close to the ground level before installation, you need to cut the drainage pipe shorter to ensure that the floor drain panel is lower than the ground.

2. For better overall effect, the position of the floor drain should not be excessively lower than the ground. If the drainage pipe is too high from the ground, you can use cement mortar to fill in the space and raise the drainage pipe, so that after the floor drain is installed, you can achieve the desired decorative effect.

3. After installing the floor drain, think about future maintenance. When filling with cement mortar, do not place the floor drain directly; instead, use some sturdy material rolled into a cylinder that matches the diameter of the drainage pipe, and connect it to the drainage pipe while ensuring it's higher than the ground before filling with the cement and mortar.

4. The connection between the floor drain and the drainage pipe should also be higher than the ground. You should fill the prepared mortar into the surrounding gaps, adjusting the floor drain to the appropriate position. Once the mortar sets, place the floor drain securely within the pipe, ensuring a tight fit against the pipe wall.
