Floor drain, floor drain is an important interface connecting the drainage system and the indoor ground. As an important part of the drainage system in the residence, its performance directly affects the quality of the indoor air. It is very important for the odor control in the bathroom. It can be said that it is a It is a very common thing, but its importance cannot be ignored. Many people will ask such a question when installing the floor drain. Are the floor drains all the same size? Are the floor drains the same size? Next, the editor will tell you about the size of the floor drain.
Types of floor drains
1. Water-sealed floor drain
The water-sealed floor drain has the longest history, and its biggest defect is that if the trap is not used for a few days, the odor and pests from the downpipe will be driven straight in due to the lack of water in the trap. Even if some manufacturers raise the trap, but There will also be the problem of long business trips or long-term non-use without deodorization. At the same time, another problem arises. The higher the water seal, the easier it is for dirt to hide in the core. These dirt are difficult to clean, and because the floor drain itself drains The most common thing is domestic sewage, so the water stored in the south or in the summer trap will stink in a few days, forming a new source of pollution.
2. Eccentric block type
That is to use a gasket, one side is fixed with a pin, and the principle of gravity eccentricity is used to seal. The disadvantage is that the seal is not tight, and the pin is easily damaged, resulting in failure;
3. Floating ball type
Use a plastic ball to float to seal the drain, but if you don’t refill the water for a while, the seal will fail.
4. Spring type
Divided into up-bomb type and down-bomb type. The up-flip type is to press the cover plate, the cover plate will bounce up, press it again, and it will reset; the down-flip type is to use the spring to stretch the gasket at the lower end of the sealing core to seal. Since the spring is made of boron iron, it is easy to rust, the elasticity gradually weakens until it fails, and the service life is not long. In addition, the spring is easy to entangle hair and fabric, and it is not easy to clean;
5. Magnet type
The gasket is sealed by the magnetic force of two magnets. Due to the poor quality of ground water, such as washing items, brushing the floor and other reasons, some iron impurities will be adsorbed on the magnet in the dirt. After a period of time, the impurity layer will cause the gasket to fail to close. The role of magnetic force will gradually weaken.
6. Gravity mechanical
The gravity movement utilizes the eternal principle of gravity, so it has the longest service life. No water seal, no dirty water, straight up and down drainage, the sealing gasket at the bottom of the sealing core will automatically close after the water is drained, the floor drain will always be in a sealed state when not in use, the deodorizing effect is the best, and it is very convenient to clean, just put Take the deodorant core down and rinse it in water for a few times, and it can be completed in less than a minute. Comprehensive comparison should be the best and most popular deodorant core at present.

Square panel 10cmX10cm
Depth: 8cm from the tile to the pipe elbow of the downpipe.
Tube diameter: 50 tubes, that is, the inner diameter is 5cm, and a slightly thinner tube is also available, but at least more than 4.5cm
This is the most used type of floor drain at present. It is also called T-shaped deodorant floor drain. It can score about 90 points for deodorization, and the water running speed is 1.4 liters per second, which is relatively fast. The use of the seal is limited. Because it relies on water storage to deodorize, it can generally only be used in the shower area, and it must be used frequently. After two days of water drying, there will be no deodorizing effect, and the water seal has a relatively fast water flow. Slow, so, all in all, it is generally recommended to use this fully automatic T-shaped deodorant floor drain!
PS: There is also the floor drain of the washing machine. The only difference between the floor drain of the washing machine and the ordinary floor drain is that there is a round hole on the panel, which is used to insert the drain pipe of the washing machine. The chrome plated one is cheaper, and the brushed one is more expensive. If it is used in some corners, look Use chrome-plated ones where you can’t reach them. If it’s in a more conspicuous place, use metal brushed ones, because the brushed ones are better at resisting scratches and won’t look old after long-term use!
Deep water seal floor drain size
Square panel 10cmX10cm
Depth 12cm – 14cm (different brands have different depths)
Tube diameter: 50mm, a slightly thinner tube with an inner diameter of 5cm is also acceptable, but at least more than 4.5cm
Because it relies on water storage to deodorize, as long as it is installed correctly, it will be 100% deodorant. The height of the water storage is about 5cm. Generally, it can guarantee that it will not return to the smell for two or three days. If it exceeds three days, it needs to be replenished with water, otherwise there will be no deodorant effect. , It is recommended to be used in the shower area. The water seal has a slow water flow speed. It is not recommended to use a water-sealed deodorant floor drain for the floor drain of the washing machine. It is best to use a T-shaped floor drain or an ultra-thin floor drain!
Ultra-thin floor drain size
Square panel 10cmX10cm
Depth: panel thickness 1.5cm, floor drain core length 2.5cm, floor drain overall depth 4cm
Tube diameter 40 tube inner diameter 4cm
Ultra-thin floor drains are generally used in old houses, because many of the old houses use 40 pipes, and now the sewer pipes in new houses are generally 50 pipes. In addition, if the pipes in the new house have been changed, change to 40 pipes or after the renovation The depth is only between 4cm and 7cm. T-type automatic deodorant floor drains cannot be used, and only this type can be used. Although this kind of floor drain is also deodorizing, the deodorizing effect is poorer. The only advantage is that the water flows quickly.
