Who should I look for to deal with the water leakage in the storage room pipeline?

Legal analysis: first find the reason of water leakage in the property, and then who will bear the corresponding responsibility according to the reason. If the drain pipe is found to be leaking, and the developer refuses to repair it during the warranty period, the owner can bring a lawsuit to the court and demand compensation for the loss. If it is clear that the upstairs water pipe is leaking, and the property still refuses to be repaired after mediation, the owner requires the property to provide the information of the upstairs owner and file a lawsuit with the court for compensation.
