1. Shallow water to seal the floor drain

The principle of shallow water sealing floor drain is to form the function of floor drain and deodorization through U-shaped double-layer holes and water storage bends. Among them, the main function of deodorization and leakage prevention depends on the existence of the medium (water). When the water flows into the floor drain , Due to the special structure of the water trap, the floor drain will always store some water, and the floor drain can also be isolated from the sewer pipe.

The floor drain is also relatively simple. In daily life, there are also some sticky impurities, which are easy to cause congestion in the water trap, and it is difficult to clean up (if it is hair, maybe it can be cleaned out with some tools). As the water bends over the water channel, it becomes narrower and narrower, resulting in slower launching. If there is no water in the trap for a long time, the room and the sewer are completely connected, which may easily cause anti-odor and peculiar smell, and may also spread germs to the room.

2. Bounce floor drain

Its price is relatively cheap, and it may be used in many land projects, but in daily life, I am afraid that few people will use it. The bouncing floor drain needs to be opened and closed by an artificial foot, and it is not odor-proof or insect-proof. For home decoration, it is not recommended to buy.

3. Gravity flip floor drain

The opening and closing of the flip cover is realized by a gravity spring, and the cost is relatively low, and it has the functions of deodorization and insect prevention. However, this gravity flip floor drain also has some disadvantages, that is, the speed of launching water is not so fast. In practical applications, when this kind of floor drain has to be used because of the problem of pipe diameter and depth, the gravity flip floor drain can be considered, and many people like it in the market.

4. T-type floor drain

The T-type floor drain can change the closed state of the magnetic sealing plate or the spring sealing plate to achieve the effect of opening or closing through the difference of water weight. The speed of launching is fast, and it can deodorize and prevent insects. It is believed to be the best of these four styles. However, no matter how good the product is, it still has certain shortcomings. After the T-shaped floor drain is used for a long time, it will lose its elasticity. At this time, the inner core of the spring needs to be replaced. However, the replacement is also very convenient. In home life, I recommend everyone to buy it.
