Legal analysis: 1. First, find a property with a decoration company. If the new house hasn't been moved in yet, it's a property matter. But if it is decoration, find a decoration company to see if it is artificial or quality problems. If you find quality problems, find a property. The property management company should be responsible for maintenance. 2. Which leak is it? The sewer supervisor still has a branch pipe with leaking grounding, which is responsible for repairing the leaking property, and the branch pipe and floor drain are leaking. The property is responsible during the warranty period, and the owner will repair it by himself outside the warranty period. The warranty period is 2 years from the date of delivery of the new house.
