Viega and Geberit have limitations, one is that the popularity of same-layer drainage in China is not high, and the other is that the price is much more expensive than traditional floor drains. As a giant of bathroom hardware, Moen provides more traditional products for domestic users.
 
As the father of one-handed hot and cold water faucets, Moen is one of the largest leading suppliers in Europe, America and China. In particular, it is worth mentioning that compared with well-known brands such as Kohler and TOTO, Moen's positioning is more popular, and the price is more pleasant.
 
The difference between domestic and European and American floor drains has been not small, and in terms of sealing and odor prevention measures, Europe and the United States emphasize the pipeline water trap. For example, Viega and Geberit use a base with a trap, and some products simply do not make a sealing structure on the floor drain, relying on the trap of the piping system to prevent odor. This method drains water quickly and can prevent odor, but it is difficult to overhaul and cannot prevent odor caused by non-standard pipe design. In China, there is a tradition of making an anti-odor structure on the floor drain, and this tradition has continued from the bell type floor drain that existed in the last century to the present. Although the anti-odor performance is weaker than that of the trap, the deodorization of the floor drain can provide the second guarantee, and the anti-odor structure of the floor drain is very useful for the anti-odor caused by the lack of trap, the depth of the water seal of the trap is not enough, and the deposition of the soil is very useful, and its maintenance and replacement is very convenient, and the amount of engineering is much lower than that of the treatment trap.
 
With the withdrawal of bell type floor drain from the historical stage, there are mainly two types of floor drains on the market: deep water seal and mechanical seal. The anti-odor performance of the water-sealed floor drain is more stable, as long as the water can be replenished frequently, the water-sealed effect will not change much, but due to the winding drainage path, the drainage speed is generally not fast. Mechanical floor drains drain relatively quickly, but there is a problem of aging, whether the cover is closed by magnetic force or spring, the sealing performance may deteriorate over time.
 
Moen's product line is relatively comprehensive, including both water-sealed floor drains and mechanical seal floor drains, which can provide choices for users with different needs. The representative of the water-sealed floor drain is 3791, and the material uses a copper chrome-plated panel and a 304 stainless steel water-sealed inner core, which is the standard configuration of the current high-quality water-sealed floor drain. At the same time, the inner core of the 3791 water seal adopts a two-sided opening, and the drainage surface is relatively large, which can speed up the drainage speed to a certain extent. Because it is a water seal, the 3791 is more suitable for use in the shower for easy hydration. However, if you are using a top-jet shower with a large amount of water, it is a good idea to test whether it drains quickly enough to avoid flooding the shower area.
 
In terms of mechanical seal floor drains, Moen is represented by the 3793 and 3964, both of which use a T-shaped spring core, that is, the cover is sealed by the force of the spring. Due to the rubber ring designed on the edge of the cover, the sealing performance is still good. These two types of floor drains are suitable for use in dry areas such as balconies where water is not often drained, and because it is impossible to replenish water frequently, dry areas are very unsuitable for using water-sealed floor drains.
 
In addition, Moen also has some special products, such as a washing machine floor drain with a washing machine drainage connection, an invisible floor drain with tiled panels, and so on. The price of all products is not too high, basically around 150 yuan, only the hidden floor drain is slightly expensive, the price is more than 200 yuan, but it should be noted that the hidden floor drain can be inlaid with tiles, but the tiles need to be purchased separately.
