To prevent dampness and odor in the bathroom, the floor drain is the key! Although the floor drain is just a small thing, if you don't choose or install it properly, your home will be filled with a foul smell in the future, especially in summer. Just thinking about it is a super annoying thing. Therefore, the selection and installation of the floor drain should not be taken lightly!

Today we mainly solve the following three problems:

What types of floor drains are there?

2. What kind of floor drain is a good one?

3. Which type of floor drain should I choose for my home?

Question 1: What types of floor drains are there?

Floor drains are generally divided into two types: water-sealed floor drains and non-water-sealed floor drains.

① Water-sealed floor drain

The floor drains in old buildings and small residential areas are usually old-fashioned water-sealed floor drains, which are particularly prone to unpleasant odors. I believe many of you here (including myself) have been deeply affected by them.

Fortunately, with the economic development and technological progress (mainly due to the strong opinions of the people), after continuous improvements by manufacturers, a new type of water-sealed floor drain has emerged.

The principle of a water-sealed floor drain is very simple. It uses a U-shaped trap to seal off odors with water. The national standard for water-sealed floor drains is that the water seal should not be less than 5cm. Therefore, floor drains with shallow water seals are not very effective, while those with deep water seals can achieve a good anti-odor effect.

A water seal, as the name suggests, must ensure that there is water stored inside. If the water dries up or the dirty water has been stored for too long, problems such as unpleasant odors will occur. However, nowadays, the new type of deep-water sealed floor drain can usually hold water for as long as two months.

② Floor drain without water seal

The floor drain without water seal is divided into two types: mechanical device seal and soft material seal.

The principle of mechanical device sealing is (students who failed in physics, please skip the following 24 words) : When the water flow reaches a certain pressure, the sealing gasket at the bottom of the floor drain core automatically opens, allowing direct drainage - does it sound very smooth and refreshing?

This is precisely the advantage of the waterless floor drain: it drains smoothly, especially the water from the washing machine, which is extremely fast, and it can also prevent the water from overflowing back.

Mechanical device seals are further classified into spring floor drains, magnetic floor drains and reverse gravity floor drains based on their specific working principles. If the mechanical device malfunctions (such as the spring rusting, magnetic force weakening, or the magnet adhering too many impurities, etc.), it will affect functions such as drainage and odor prevention, and needs to be replaced.

The floor drain sealed with soft materials uses silicone, which is the thing the baby uses to suck on the pacifier. This kind of floor drain drains very smoothly

Question 2: What kind of floor drain is a good one?

Fast drainage, anti-clogging and anti-backflow.

Relatively speaking, the waterless floor drain drains the water from the washing machine faster than the waterless floor drain.

2. Anti-odor, anti-reverse smell and pest control.

Relatively speaking, the anti-odor function of the new type of water-sealed floor drain is more reliable.

3. Easy to clean.

Female students who have lived in old buildings may all have had the experience of their hair blocking the drain. If not cleaned in time, it is easy to cause blockage or unpleasant smell...

Fortunately, most of the new types of floor drains nowadays adopt built-in floor drain cores, which can be easily removed for cleaning

In addition, some new types of floor drain cores can be directly inserted into the old ones, eliminating the trouble of replacing the entire floor drain. This is definitely a blessing for homeowners of old houses. ↓ Have you chosen the right floor drain for your home? After reading these, you will know

Question 3: Which type of floor drain should I choose for my home?

The editor consulted the opinions of experts and decoration gurus and offers the following suggestions to everyone:

1. Frequently used water areas such as the shower area: Deep-water sealed floor drain

As water often comes out, it is safer to use water-sealed floor drains in these areas. The drainage from a shower is definitely not as powerful as that from a laundry. A deep-water floor drain is sufficient.

2. Areas such as kitchens and balconies where water is not frequently used: Floor drains without water seals

As mentioned earlier, a water-sealed floor drain can only function properly if there is still water inside. Therefore, for places like kitchens and balconies that require occasional temporary drainage, it is best to choose floor drains without water seals. Because the usage intensity is not high, there is basically no need to worry about the problem of inability to drain water due to mechanical failure.

3. Washing machine floor drain: direct-discharge floor drain without water seal

The drainage of a washing machine can be described as "rapid". Therefore, a water-sealed floor drain with smooth drainage is the best choice, especially a silicone floor drain - of course, it is a bit expensive.

Finally, what the editor wants to say is that when it comes to floor drains, there is no such thing as perfect, once-and-for-all, or good quality at a low price. Don't buy cheap floor drains that cost only a dozen or so yuan each. Even the best floor drains need to be cleaned regularly.
