What should I do if the bathroom leaks? There is a leak in the bathroom downstairs.

There are many reasons for water leakage in the bathroom. First, we should find the leaking place and judge what the reason is. The specific reasons are as follows: 1. Pipeline leaks. If the pipeline inside the waterproof layer of the building leaks, there is no other way but to pry open the waterproof layer and repair the pipeline. If the external water supply pipe leaks, repair the pipe and coat the wall with waterproof material. 2. In another case, the ground infiltrates downwards. According to the traditional method, it is to dig tiles, break the waterproof layer, re-make the waterproof layer, and then lay tiles. After the waterproof construction, the construction site can't be drenched with water within 24 hours. That's about it, for reference only, and I hope I can help you solve the problem as soon as possible.
