What should I do with these hateful attributes?

You're passing the buck. Your home was not waterproof when it was decorated. The reason why the property can't find the water leakage point is because the concealed works can't be seen by the naked eye. If you want to find out the problem, you can only judge it through partial disassembly and decoration. If a formal decoration company is invited, the responsibility lies with the decoration company. How can you take it out on your property? The water supply is normal, and the water should be checked. If it is a decoration quality problem, the decoration company is responsible. Because the quality problem is not limited by the warranty period, if it is guerrilla decoration, then you are responsible. According to the Tort Liability Law, you have violated the property downstairs. The property is a coordinating unit, so you have no reason to blame the property. Another possibility is that the public sewer well leaks water and the inner wall of the pipeline well is not waterproof. You must cooperate with the property inspection. Decoration part of the developer free of warranty, structure.
