Next, fill the area under the drain outlet with mortar, and apply a secondary waterproofing layer on the ground. The wall waterproofing must reach the same height as the primary waterproofing. After that, fill with mortar, let it dry, lay a layer of wire mesh, and finally install the flooring.

What are the Precautions for Installing a Bathroom Floor Drain?

1. Before going to the market to select materials, you must have a plan. Do not act blindly, as this can easily lead to unnecessary expenses. First, clarify the diameter of the drainage pipe, which is usually 50mm PVC. If the material is cast iron, the diameter will need to be larger. Ensure that the diameter of the drainage pipe matches that of the floor drain. For certain PVC pipes that require repairs during installation, prioritize floor drains that do not need maintenance.

2. Consider the location of the floor drain installation. You should find a suitable position before installation, as this will make it easier when laying tiles later. It’s best to place it at the edge of the tiles for easier drainage.

3. When connecting the floor drain to the drainage outlet, you usually need to insert a small part of the pipe into the drainage pipe, aligning it with the drain center below. Use a layer of cement as a base. If the drainage pipe sways or has gaps, it is easy to create leaks. Therefore, ensure a tight fit, and seal it properly using professional glue or glass sealant.

In summary：the above is the method for installing a secondary drainage floor drain. From the article, we can see that when installing a floor drain, it is essential to consider all aspects and ensure that the specifications and quality of the floor drain meet standards. This helps to guarantee the quality of the project and reduce unnecessary troubles. I hope this helps everyone.
