Why does the bathroom smell bad when it is windy?

Whenever it is windy and rainy, there is always an inexplicable smell in the bathroom, is the smell of the bathroom really related to the weather?

All main sewer pipes have an outlet cap on the roof, which is to ensure that there is enough atmospheric pressure in the main sewer pipe to make the sewage drain in time. However, when the wind blows, the air pressure in the sewer pipe increases, and the dirty gas in the sewer pipe will be discharged to the home through the empty pipe, which will cause the smell in the bathroom at home. This situation is generally caused by the lack of a drain trap.

Causes and solutions of anti-odor in the bathroom:

Keep the bathroom clean and clean on a daily basis; Keep toilets and other toilets clean;

The main reason for the backsmell of the floor drain is that the selected floor drain core does not have a water seal, which leads to the dirty air in the sewer pipe directly penetrating into the room; The treatment method is to replace the floor drain product with water seal and anti-odor function;

The sewer pipe of the washbasin does not have a trap, and the solution is to design the sewer pipe as a drain with a trap;

The connection between the sewer pipe of the washbasin and the reserved sewer pipe is not tightly sealed, and the solution is to seal the connection of the sewer pipe;

The flush gasket of the toilet bowl and the sewer pipe of the toilet bowl are not tightly sealed, and the solution is to adjust the position of the gasket and seal the contact part between the toilet base and the ground at the same time;
