What should I do if the toilet public sewer leaks and the property is not maintained?

The leakage of public sewer pipes in toilets has not been maintained. If the property is not maintained due to the influence of your ceiling and wall seal, then you should remove the affected parts to provide convenience. If the affected part is demolished and the property is still not maintained, you can complain to the superior company of the property or even bring a lawsuit to the court.
