Magnetic levitation floor drain: The magnetic levitation floor drain mentioned in the promotional slogans of various types of floor drains is essentially based on the principle of elastic sealing, using magnetic levitation technology to replace the spring's elasticity and solve the problem of the spring's elasticity changing over time.

Advantages: Good sealing performance and long duration.

Disadvantage: High price.

Spring type/press type spring floor drain: This type of floor drain is installed with a spring in the inner core. When there is no water or little water, the spring springs up, lifting the sealing ring to close the drainage channel. The water in the local drain reaches a certain height, and through the action of gravity, the spring is pressed down by the water, and the sealing ring opens to achieve drainage.

Advantages: The effect of odor and insect prevention is relatively good.

Disadvantages: Long term use can result in poor sealing performance and changes in elasticity, requiring replacement every few years.

Gravity type floor drain: The cover plate is sealed by gravity to seal the leak. When water passes through, the leak is pushed open by water, and when there is no water, it is closed.

Advantages: Simple structure, easy maintenance and replacement

Disadvantage: The airtightness is easily damaged

Magnet type floor drain: Built in magnet, it adheres to each other when there is no water, and drainage can be achieved when the water pressure is greater than the magnetic suction.

Advantages: It also has good odor and insect prevention effects and high cost-effectiveness.

Disadvantages: Some iron impurities are easily adsorbed on the magnet, and prolonged use can cause the sealing ring to fail to close and not have a deodorizing effect.

Water sealed floor drain: It is divided into shallow water seal and deep water seal, with N-shaped or U-shaped pipes used to store water internally to prevent insects and odors.

Advantages: Simple structure and low cost.

Disadvantage: If stored water is not used for a long time and evaporates dry, it will lose its odor and insect prevention effect.
