The floor drain should have a draft of 5 cm (but this floor drain height is too high and the floor of the new building has been thinned so it cannot be installed)
In the past, in addition to water traps designed for toilets, there were anti-water bends in toilets and toilets and kitchen floor drains. There were anti-water bends in the toilets and the water was often used to seal off the odors. In order to increase the storey height and reduce costs, many newly-built communities have already eliminated the anti-water bend below the floor drain. Instead, they have adopted a new anti-odor floor drain to ensure that the odor of the sewer is not dispersed. These deodorant floor drains are often made of pvc material and are far inferior to the stainless steel and copper floor drains on the market. Many homeowners have replaced the more beautiful floor drains during the renovation period. Some of them have experienced unpleasant smells during their lives. This is mainly caused by the use of substandard drains. Qualified water seal layer should be 5 cm, the reporter found that some counterfeit leak seal layer is only 1 to 2 cm, is the state in 1999 has been explicitly stipulated that out of the building materials products, if from such a source continuously leaking It's not hard to imagine an odor.
Sealed down the water pipe connection part Some people asked the decoration company to reinstall the deodorant floor drain. It was effective in the first few days. Later it was found that there was still an unusual smell, and it was not leaked from the floor drain. The reporter interviewed relevant decoration experts. Experts believe that inspections should be conducted from the aspects of sealing, such as the connection between the sink water pipe and the kitchen drain pipe and the sewer pipe. If these details are not strictly sealed, it will become a channel for the sewer odor to enter the room. Because the water interface is located in a relatively hidden place, it is easy to overlook the completion of the renovation and acceptance, should cause the owner's attention. The specific practice suggested by the experts is to ask the decoration workers to seal the gap at the interface with glass glue or other adhesive so that the gas cannot be emitted.
Traditional and new type of floor drain structure The traditional floor drain on the market, that is, the water seal is mainly composed of three parts: the upper cover, the floor drain body and the floating cover. When the floating cover has water, it can float up and down with the water in the floor drain body. When there is no water or water, Cover the drain pipe to prevent odor from flowing from the drain pipe to the inside. Although the floating cover can cover the sewage pipe, in order to achieve better results, the depth of the water seal layer in the floor drain needs to be maintained. Therefore, the water should be filled to maintain the depth of the liquid surface. However, due to natural conditions, climate, etc., the water seal is easily damaged by the negative pressure formed in the pipeline and loses its deodorant function. Or if you do not live in your home for a long time, the effect of deodorant drain will decrease.
The new type of floor drain is a self-sealing floor drain consisting of a shell and a unique piston-type structural core. It is very clever use of the mechanical principle, reverse the use of the flow of water to open and close the device, when the drainage is completed, the seal automatically closed to form a complete seal.
The new type of floor drain will be found in the building materials market. In the past, there were only floor drains of cast iron dumplings, and the style of floor drains can now be much more. From the material points are mainly stainless steel floor drain, pvc floor drain and copper floor drain.
