What to do if the bathroom drain smells

.First of all, check whether the sewer is unobstructed and whether there are any foreign objects affecting the drainage.

2.If there is a blockage, you can pour an appropriate amount of alkali into the sewer, which is more effective in removing grease and rust from the pipes.

3.If the sewer is not blocked but the smell returns, you can use the principle of water sealing to 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.

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

The smell in the sewer is very strong, in order to prevent the smell from returning, it is necessary to close the basin flap drain frequently, and seal the connection between the sewer pipe and the pipe. The floor drain of the washing machine should be sealed, and the floor drain with good sealing should be selected and checked and cleaned frequently.

Rinse with water to reduce odors.
