There are many kinds of small hardware for home improvement, how to choose, what area to install, if you have any doubts, you can understand most of it by reading this article, floor drain article
1. Floor drain valve core
1.1U type floor drain
The principle is very simple, that is, the principle of the trap fluid seal, and the disadvantages are also obvious. If it is not used for a long time, the water will evaporate and it will not keep off the odor. Therefore, it can only be installed in the shower area, and if the odor control effect is to be good, the core must be made longer, so that the evaporation resistance time can be longer, but if the drain pipe is left too shallow, it will easily get stuck in the construction. The drainage speed of the floor drain is relatively slow. If the shower area is installed, it is recommended to install more than two.
1.2T type floor drain
The principle of T-shaped floor drain is to use spring rebound to prevent odor. This kind of drainage is faster than U-shaped, but the shortcomings are obvious. If the water is flushed frequently, the spring will inevitably age quickly. Therefore, it is recommended to install it in a dry area that is not frequently flushed, such as leak-proof water. Of course, it is not impossible to install it in the shower area. Anyway, the spool can be easily removed if it is broken. The spool of Ma Yun’s house is 9 yuan and 9 free shipping.
This kind of T-spool actually has an improved version now, that is, the spring is replaced by a magnet to attract and repel back and forth, which is much more durable than a spring. The price of a certain gram of patent is a bit touching (although the cost is a few yuan more expensive at most)
1.3 Floor drain
The principle of the flap floor drain is to use a gravity block to return to its place to prevent odor. A certain boat uses this kind of plastic core. This drainage speed is okay. The types of cores are plastic, stainless steel, and copper, and the common ones in the market are mainly plastic and stainless steel.
This kind of spool requires more workmanship, especially stainless steel. Due to the lever movable joint, it is easy to seal tightly. If the bottom drain pipe does not have a trap to prevent odor, pay attention to whether the spool is tightly sealed.
1.4 Side sealed magnetic floor drain
A certain boat also uses this kind of spool. This kind of spool has a fast drainage speed, but it has the disadvantage that the magnets on both ends tend to attract small black spots of iron, and the seal will not be tight after a long time. However, this kind of spool is simple and cheap to clean and replace.
