Leakage characteristics of toilet

Who is responsible for the leakage of the main toilet pipe? First of all, we must confirm the reason why the supervisor is leaking. If it is the leakage caused by decoration, it is the responsibility of the decoration company. If it is not caused by the decoration company, it is the responsibility of the property. At this time, if the warranty period of the main pipeline has not expired, the property can be taken care of by the construction unit. If the warranty period expires, the property can only compensate itself.
