The floor drain must be chosen carefully. The selection order is: material > drainage speed > anti-odor and anti-insect

1. Choose the right type of floor drain

1) Spring-type floor drain. When the water pressure exerted by the sealing gasket exceeds the spring force,

the sealing gasket opens and automatically drains the water. Disadvantage: Over time, the spring force

will decrease and the spring is prone to getting clogged with hair.
2) Magnetic floor drain: The magnetic force is regarded as the spring-like tension. When the weight of the

water is greater than the electromagnetic force between the magnets, the sealing pad opens and automatically

drains the water. Disadvantages: The electromagnetic force between the magnets is not uniformly distributed like a spring,

and the drainage is not stable. Additionally, the magnets will attract some magnetizable substances,

resulting in a weakened magnetic force and ultimately incomplete sealing.
3) Gravity-type floor drains can be divided into flap-type floor drains and float-type floor drains.

The flap-type floor drains are quite common, but they have poor odor prevention capabilities.

The upgraded side-flap type floor drains have good odor prevention and drainage performance.

The float-type floor drains use the buoyancy of water to control the closure of the outlet,

but they are prone to getting stuck by debris and cannot be fully closed, resulting in poor odor prevention performance.

This type of floor drain has the fastest drainage speed.
4) Silicone drain cover: By utilizing the elastic rebound property of silicone, when there is water, the weight of the

water presses down on the silicone seal, allowing water to drain after the process is completed. This design offers good odor prevention and is also easy to clean.
5) Water-sealed floor drains come in both shallow and deep types. Both have a water trap to prevent odors.

The shallow water type has a slower drainage speed, while the deep water type has a generally faster drainage speed.

The deep water type is preferred, but it should be considered whether the depth of the bathroom is sufficient for installation.
