What to do about the smell of the drain The bathroom is the smell of the reverse from the sewer

First, check whether the sewer is unobstructed and whether there are foreign objects affecting the drainage. If there is a blockage, unclog the drain first. If the sewer is not blocked, but the smell returns, 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 reasons for the smell of the sewer are the smell of the bathroom, which is likely to be caused by floor drains, and some floor drains will also cause problems such as sewage overflow and insect breeding.

It may be that the anti-odor effect of the floor drain itself is not very good, you can go to the store to buy a good anti-odor effect, so that the smell in the sewer is difficult to come up. 3. Ordinary sewer odor: If it is just an ordinary sewer pipe odor, you can add a filtered metal mesh cover to the sewer to filter out larger solids such as hair and vegetable residue.

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. Fourth, 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. I hope my answer is helpful to you.
