The drains in the kitchen and toilet are smelly, how to clean them

This smell does not come from the toilet, because there is a pipe under the toilet"Barbs'It was designed to prevent"Smell'Reverse flow, the urinal is cleaned often and it is no problem.

The smell you are talking about is coming from the sewer, because all the sewer pipes are connected (including the toilet), this phenomenon is caused by the sewer mouth is not tightly covered, you still find a way in this place, and you can cover it tightly.

The floor drain in the room should have a draft of 5 cm, in addition to the flush toilet drain design when building a house in the past, the toilet drain drain also has a reverse bend, and the bathroom and kitchen floor drain also have a reverse bend, usually relying 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, resulting in bathroom odors, in this case, you can be more slippery with an anti-odor floor drain, the odor-proof floor drain on the market is mainly composed of three parts: the upper cover, the floor drain body and the floating cover, in which the floating cover can float up and down with the water in the floor drain body when there is water, and the sewer pipe will be covered when there is no water or less water, Prevent odors from backing up from the sewer pipes into the room.

Although the floating lid can be used to cover the sewer pipe, in order to achieve better results, it is necessary to maintain the depth of the water seal in the floor drain, so it should be filled with water to maintain the depth of the liquid level when used.

If the sewer pipe of the pool is not installed with a bend, and the sewer and the room form a straight through, resulting in an odor, then a bend can be installed.

If this is not enough, check the connection between the sewer pipe of the sink and the sewer, these details will become a passage for the sewer odor to enter the room if not strictly sealed. Since the sewer interface is in a relatively hidden place, it is easy to ignore it when the decoration is completed and accepted, and it should attract the attention of the owner. The specific practice recommended by experts is to ask the renovation worker to seal the gap at the interface with glass glue or other adhesive so that the gas cannot be discharged.
