It was caused by a leak in the adjacent residents' bathrooms on the upper floors.
Due to the negligence of the construction party in the installation of the decoration bedpan in the decoration of the adjacent household toilet on the upper floor, the connection between the bedpan and the sewer main pipeline is not tightly sealed, resulting in the leakage of the bedpan in the drainage process, and the "white saline" phenomenon that infiltrates into the top of the adjacent household toilet on the lower floor.
Therefore, the adjacent residents on the upper floor can be contacted to rectify the toilet bedpan interface, and reconnect the waterproof measures such as leakage prevention of the sealed sewer main pipe interface.
