Does the toilet smell bad to the property?

The toilet smells, but your floor drain and sewer are not closed properly. This kind of thing does not belong to property management. It's a small matter, too. I can handle it myself. The aftertaste part mainly includes floor drain, sewer pipe of washbasin and sewer port under kitchen sink. As long as all these outlets connected to the main sewer road are sealed, the problem of odor return can be eliminated. The treatment method is that the floor drain adopts water-sealed floor drain, and the threaded pipes of washbasin and vegetable basin are wrapped in convenient plastic bags and inserted into the sewer port. This will prevent the smell from reappearing.
