What to do if the toilet drain smells bad

1. First of all, check whether the sewer is smooth and whether there are foreign objects affecting the drainage. If there is a blockage, unclog the drain first. If the subordinate is not blocked, but the smell is returned, you can use the principle of water sealing, fill a thin plastic bag with clean water, seal the mouth of the bag, and put it on the mouth of the sewer to cover it tightly, so as to seal the odor.

In addition, it is best to keep clean water in the bowl-shaped water reservoir structure at the sewer mouth at the same time, which is more effective in preventing odors from coming out.

2. Floor drain odor: Most of the causes of sewer odor are toilet odor, which is likely to be caused by floor drains, and some floor drains will also cause problems such as sewage overflow and insect breeding.

Then the position of the sewer mouth can be covered with a mesh bag, covering the position of the sewer mouth, it should be noted that the bag must be fixed well, so as not to be washed into the sewer by the large flow of water.

4. The floor drain of the bathroom is a key point: in the past, in addition to the design of the flush toilet drain when building a house, the bathroom and kitchen floor drain also have a reverse bend, and the water seal usually relies on the sealing of the water to prevent the odor. At present, in order to increase the floor height and reduce the cost, many new residential areas have canceled the anti-water bend under the floor drain, and instead adopted a new type of anti-odor floor drain to ensure that the sewer does not disperse.

1. The toilet will smell bad, which may be caused by inadequate installation, or it may be caused by its own unreasonable structure. For example, if the water seal is not tight, it will cause the sewage pipe of the toilet to have an odor. Therefore, if you want to solve the problem of toilet odor, you must first find out the cause and then solve it.

2. When the toilet in the bathroom has an odor, if its water seal is normal and there is no omission, then it is likely to be caused by inadequate installation. Because there is no toilet installed, the butt between the sewage pipe and the water outlet is not tightly sealed, so the odor is easy to escape.

3. In today's basic residences, there are basically exhaust outlets on the top floor with sewage pipes, so if the exhaust port is blocked, it will also cause the toilet to have an odor. In addition, when the toilet has an unpleasant smell, it may also be caused by other bathroom products such as drains or wash basins, so it is necessary to check them one by one.
