Three common household drains
Although the floor drain is small, it is critical to choose a suitable and practical floor drain because it is very important for the odor control in the bathroom, so its performance directly affects the indoor air quality. The following is a brief introduction to the common three kinds of floor drains, I believe it will help you buy out.
Floor drains are mainly divided into three types: water deodorant floor drains, sealed deodorant floor drains and three floor drains.
Water deodorant floor drain is the most traditional and common. It mainly uses the tightness of water to prevent the emission of odors. In the structure of floor drains, water storage bays are the key. Should try to choose a deeper water storage bay, can not just look beautiful. According to relevant standards, the new type of floor drain shall ensure that the height of the water seal is 5 cm, and there is a certain ability to keep the water seal from drying out to prevent the spread of odor. Some ultra-thin floor drains are beautiful, but the deodorant effect is not obvious.
Sealed deodorant floor drain is to add a cover on the floating cover to seal the drain body to prevent odor. The advantage of this floor drain is the appearance of modern fashion, the disadvantage is that each time you use to bend over to lift the lid, it is more troublesome. There is now an improved sealed floor drain, with a spring on the top cover. When used, use the pedal top cover. The top cover will spring up and step back when not in use.
The three floor drains are by far the most advanced deodorant floor drains. It installs a small floating ball at the drain pipe at the bottom of the floor drain. Daily use of the water pressure and air pressure in the sewage pipeline will hold the ball up and make it completely closed with the floor drain, thus playing the role of deodorant, pest control and overflow prevention. .
