When renovating a home, the floor drain may seem unremarkable, but its role is crucial. Let’s take a look at what the typical diameter of a floor drain is and the considerations for its installation.
Typical Diameter of a Floor Drain
The common diameters are generally 3 inches and 4 inches, with the cover plate usually measuring around 10 centimeters. Depending on the style of the drain, it can be square, round, or rectangular. Typically, household floor drains range from 90mm x 90mm to 150mm x 150mm. The indoor air quality heavily depends on the performance of the floor drain.
Considerations for Installing a Floor Drain
1. When installing, the floor drain should be done concurrently with the tiling. The installation of a floor drain is relatively simple. You just need to choose the appropriate product based on the actual dimensions, then apply cement mortar evenly to the back of the drain and bond it closely to the wastewater pipe. Finally, simply cover it with the lid.
2. The bathroom is an area that uses water frequently. Therefore, when installing the floor drain, it is essential to maintain a sufficient slope to aid in drainage. If the floor is too flat and lacks slope, it can easily lead to water accumulation issues.
3. Before installation, make sure to clean the impurities inside the water pipes. If there are stains at the pipe entrance, they should also be removed. Next, wrap the pipe to avoid debris falling into it, which could cause blockages. Additionally, check whether the distance between the floor and the pipe is reasonable. If it is too close, a section of the pipe should be cut away. The cement around the floor drain should not be applied too thick, or it will complicate the installation.
