Which department should solve the odor in the underground pipeline of the house?

1. Property inquirer for property management;

2. If there is no property management, if the warranty period has not passed, find a builder;

3. If the above two items are not available, consult with the upstairs residents and ask the workers to do it for them and share the expenses.

4. When the above three items are useless, now the victim is on the first floor. In desperation, I will teach you to do this:

Block the sewer, so that the second, third, fourth and fifth floors are blocked layer by layer. If you live on the first floor, the problem of water inflow can be easily solved. The higher you live, the harder it is. Finally, everyone was forced to pay for the repairs.

That's what I did. It worked.
