1) The connection between the sealed sink drain pipe and the kitchen drain pipe and the sewer. These details, if not tightly sealed, will become a way for the odor of dirt to enter the room. Because the water seam is a relatively concealed place, it is easy to be neglected when decorating, and the owner should pay attention to it when checking and accepting. Experts suggest that the specific method is to invite decoration workers to use glass glue or other adhesives to seal the seam gap, so that the gas can not be emitted.
2) In the past, when building a house, the floor drain should be painted 5 cm. In addition to the design of backwater bend for toilet water, the floor drain of toilet and kitchen also has backwater bend. Usually, water seal is used to prevent odor. Now, in order to increase the height and reduce the cost, many new residential areas have eliminated the backwater bend under the floor drain and adopted a new type of odor-proof floor drain to ensure that the odor of sewage is not discharged. These odor-proof floor drains are often made of PVC materials, which are far less beautiful than stainless steel and copper floor drains sold on the market. Many owners change the floor drains which look beautiful and are substandard in actual quality when decorating, resulting in bad smell in toilets.
At present, the deodorizing floor drain in the market is mainly composed of upper cover, floor drain body and floating cover. When the floating cover has water, it can float up and down with the water in the floor drain. When there is no water or very little water, the cover of the drain pipe will die to prevent the odor from entering the room. Although floating caps can be used to cover drainage pipelines, it is necessary to maintain the depth of water seal layer in ground leakage for better effect. Therefore, it should be filled with water to maintain the depth of the liquid surface.
