There is a water seal under the filter screen of the anti-odor floor drain. The water in the water storage cylinder can block the odor in the pipeline and play an anti-odor role. However, the ordinary floor drain does not have a water seal device to block and prevent odors under the filter screen.

2. There is a hemispherical cover under the filter screen of the anti-odor floor drain. It is usually placed over the drain outlet. When water passes through, lift the cover and the water will flow down. When the water is covered without a lid, the smell won't rise. There is no lid under the filter screen of a regular floor drain.

Water seal is one of the important features of floor drains with water seals. When choosing, it is necessary to understand whether the water seal depth of the product reaches 50mm. At present, the water seal depth of some floor drains on the market is only 10 to 20mm, which cannot effectively block the foul smell from the sewer.

The height of the floor drain grate surface can be adjusted, with an adjustable height of no less than 35mm to ensure that the floor drain surface elevation is level with the ground after the floor decoration is completed. The installation of a waterproof protection ring on the floor drain is to meet the waterproofing requirements when the floor drain is installed on the floor slab.

For floor drains located in underground garage car passages or load-bearing areas, the strength of their grates should be able to meet the corresponding load requirements. Stainless steel is the best choice.
