The floor drain is a device for diverting water and sewage in our home. Regardless of its small size, the floor drain plays a huge role in life. If the floor drain is well designed, it may cause the floor drain to smell and affect the indoor environment.
So which floor drain has the best anti-odor effect? Let’s compare the working principles of the four common floor drains on the market.
1. Water-sealed floor drain
The design of the water-sealed floor drain is a bell-type structure, which is a non-straight-through sealed floor drain. The water-sealed floor drain is buckled on the mouth of the sewer pipe with a bell to obtain a “U”-shaped water storage bend. The water in the water storage bend seals the smell of the sewer, so it is called “water seal”.
The water seal floor drain is an old-fashioned floor drain, so there are many defects in the design: for example, the water seal height of many water seals now only reaches 10-20mm. Once it dries up, the odor of the sewer pipe will overflow into the room; , it can only be to delay the time of back odor.
Moreover, the deeper the water seal, the better. One is because the installation height is limited, and the other is that as the water seal deepens, there will be more attachments on the inner wall. After a long time, sewage with a lot of dirt will also become smelly.
2. Floor drain with flap core
The advantage of the flap core floor drain is drainage rather than deodorization. This kind of floor drain has a fast drainage speed, but the pins are easy to break, the sealing effect is not good, and the natural deodorization effect is relatively poor.
3. Silicone sealed floor drain
Silicone floor drain is a non-water-sealed floor drain. Its material is the silicone material that is generally used as a pacifier. Although the sealing effect is good, it is not corrosion-resistant or pest-proof, so the service life is usually relatively short. If it is a floor drain used for washing machine drainage, it is not recommended to choose this material, because the water for washing clothes is highly corrosive sewage.
4. Straight-through sealed floor drain
The straight-through sealed floor drain is one of the more common floor drains on the market, with three working modes: spring, magnet and reverse gravity.
1. The first type is a built-in spring in the floor drain core. Under normal circumstances, the bottom gasket of the floor drain core can absorb and seal. After the water is drained, the gasket can be returned to its original position with the help of elastic force.
The deodorizing effect of the floor drain in this way is good, but the service life will not be too long. Because the spring itself is made of iron, it is easy to rust and produce harmful bacteria after being in contact with dirty water for a long time, which is not a healthy choice.
2. The second is to use the suction force of the magnet to return the sealing gasket to realize automatic sealing after the water is drained.
However, when encountering metal particles, impurities are easily adsorbed on the magnet, and the magnetism will decrease in the long run, so that it is difficult for the gasket to return. The performance of this type of floor drain is inconsistent, but the core of the floor drain can be replaced without replacing the entire floor drain.
3. There is also a reverse-gravity straight-through airtight floor drain, which uses the gravity of the water itself to open the sealing cover, and will not be afraid of affecting the service life due to the corrosion of dirty water like magnets or springs. The sealing point at the bottom is a sealing ring design, which can better prevent odors and pests.
After reading the introduction of the floor drain above, do you still know which floor drain has the best anti-odor effect? To sum up, it seems that the straight-through floor drain has the better anti-odor effect. If you are considering replacing the floor drain, I hope the above information will be helpful to you .
