How to decorate to avoid backwatering and smelling in the kitchen and toilet

Step 1 The floor drain of the bathroom is a key point, in the past, in addition to the flush toilet drain design with a reverse bend, the bathroom and kitchen floor drain drain also have a reverse bend, usually rely on the sealing of water to prevent odors. At present, in order to increase the floor height and reduce the cost, many new residential areas have canceled the anti-drain under the floor drain, but adopted a new type of anti-odor floor drain to ensure that the sewer odor does not escape. These odor-proof floor drains are often made of PVC materials, far less beautiful than the stainless steel and copper floor drains sold on the market, many owners have replaced the floor drains that look beautiful and the actual quality is unqualified when decorating, the water seal of the floor drain is very shallow, and the smell of the sewer pipe cannot be isolated, so it leads to a peculiar smell in the bathroom, so it is recommended not to replace it easily, if it has been replaced, it can be replaced with an odor-proof floor drain, so that it will not be bad smell.

2. The sewer pipe of the sink is also a place where the smell often appears, 1. The connection between the sewer pipe and the sewer of some sinks is not done well during construction, there is no strict sealing, and the smell will enter the room directly from the gap, and the treatment method is: ask the worker to seal the gap at the interface with glass glue or other adhesives, so that the gas cannot be discharged. 2. Some sewer pipes are made into anti-water bends with hoses, and after a long time, the hose is deformed into a straight pipe, and the water seal is lost, and the sewer and the room form a straight through, and the smell directly enters the room

Replace the hose with a dedicated anti-water hose.
