The wall downstairs was peeling, and he found someone to come and see it, and said that it was water

Kiss, this time I encountered trouble, the downstairs wall peeled off, check whether the water pipe leaked, whether the bathroom waterproofing is done, if you are sure, kiss is the need to redo the toilet waterproofing, this price is not expensive, pure hand forget to adopt.

This may be the case.

In general, leaks in the bathroom will affect the outside walls and floors of your own bathroom, the top of the downstairs bathroom, and the top and walls (from top to bottom) of the outside walls of the downstairs bathroom.

Solution: 1. First do a pressure test on the plumbing pipeline in the bathroom to check whether there is a leakage of the buried water pipeline. If the pressure proves that the pipeline has leakage problems, the leaking pipeline should be repaired first (generally speaking, most of the leakage of water pipelines appears in the position of the joint, which can be checked from the location of the joint); If there is no leakage in the water pipeline, it means that the waterproof layer is damaged, and the following step 2 is followed.

2. Because of the leakage to the outer wall of the downstairs bathroom, it means that the waterproof layer is damaged at the junction of the wall and the ground near the bathroom, and the tiles of the wall and ground are smashed open for maintenance.
