The floor drain is a device that drains water out of the bathroom. Its function is no ordinary one. The floor drain is an important interface connecting the drainage pipe system with the indoor floor. As an important component of the drainage system in a residence, its performance directly affects the quality of indoor air and is very important for controlling the odor in the bathroom. Although floor drains are small, there are many issues to consider when choosing a suitable one.

Under the premise that the existing building structure cannot be changed, floor drain odor prevention should be a good solution to the odor problem. How to prevent odors in floor drains? Then we have to first understand its structure. A common floor drain usually consists of a floor drain body and a floating cover. The floor drain body refers to the component that forms the water seal of the floor drain, with the main part being the water storage bay. As many floor drains currently rely mainly on water seals to prevent odors, the depth of this structure and whether the design is reasonable determine the size of the floor drain's sewage discharge capacity and odor prevention capacity. When there is water in the floating cover, it can float up and down with the water inside the floor drain. Many floating covers are separately connected to a bell cover under them. When there is no water or there is little water, the drain pipe is completely covered to prevent the odor from flowing back into the room through the drain pipe.

Floor drains have specific uses. In terms of their functions, floor drains can be divided into two types: those for general use and those specifically designed for washing machines.

The special floor drain for washing machines has a round hole in the middle, which can be inserted into the drain pipe. It is covered with a rotatable cover. When not in use, it can be closed, and when needed, it can be unscrewed, which is very convenient. However, its anti-odor function is not as good as that of ordinary floor drains. However, as experts suggest that floor drains should not be set up or installed too many times in a room, there are currently some floor drains that are dual-purpose.

The selection of materials is crucial. On the market, floor drains are mainly classified into three types based on their materials: stainless steel floor drains, PVC floor drains, and all-copper floor drains.

Since the floor drain is buried underground and requires good sealing, it cannot be replaced frequently. Therefore, choosing the appropriate material is very important. Among them, all-copper floor drains have begun to occupy an increasingly large share due to their performance. Stainless steel floor drains were quite popular a few years ago due to their beautiful appearance. However, according to relevant professionals, stainless steel is expensive and has a thin coating, so it still cannot escape the fate of rusting within a few years. pvc floor drains are inexpensive and have a good anti-odor effect, but the material is too brittle and prone to aging. Especially in the winter in the north where the temperature is low, they need to be replaced after a short period of use. Therefore, the market is not optimistic about them. At present, the most common type on the market is the all-copper chrome-plated floor drain. It has a thick coating. Even if copper rust forms over time, it is relatively easy to clean. Generally speaking, the all-copper floor drain can be used for at least six years.

In the competition of anti-odor floor drains, apart from smooth water drainage, anti-odor is the most crucial aspect.

Nowadays, most floor drains on the market have anti-odor functions. Depending on the advancement of the anti-odor principle, facilities and methods, their prices are not the same. When making a purchase, one should choose a suitable one according to their own needs.

It is essential to choose products of good quality; otherwise, it will have a significant impact on the bathroom.
