You should negotiate with the residents upstairs to check whether it is a pipeline problem or a waterproof layer problem, no matter what, you have to solve it in the upstairs construction, the following blockage is not blocked, this kind of thing is very troublesome, because the upstairs residents themselves have no impact, so they generally will not go to repair, and the downstairs residents have to get the consent of the upstairs to repair themselves, and there will be a contradiction if it is not good, if there is no property management, they can only come forward to negotiate and solve it.

Under normal circumstances, they are not connected, and in order to prevent the odor from rising, under normal circumstances, the pipeline has a bend and relies on stagnant water to block the odor.

Start by identifying where the water is leaking. If it is only a joint leakage, under the premise that the quality of the pipe is qualified, the joint can be replaced or a leak-proof sealing tape and AB sealant can be added to the joint; If the quality of the pipe is not good, the pipe should be replaced. You can also apply the adjusted AB glue in the leaking place, and then wrap a layer of ribbon on it, so that the ribbon is soaked with AB glue and then apply a layer of AB glue on the ribbon, and the whole process can be divided into two or many times.
