How to solve the water leakage of wall concealed pipe? Who can talk about it?

Wall leakage: 1: The reasons for water leakage may be improper concealed pipes of upper water pipes, poor quality of water pipes and rust of galvanized pipes. This situation is very troublesome, and it can only be corrected where it is leaked and eliminated where it is changed. 2. The waterproof layer height of the light wall in the shower area can't reach 1.8m, so the light wall is easy to get wet in the humid environment all the year round. You can change the nozzle angle during the shower to avoid water spraying on the light wall; Or refit the shower head to the load-bearing wall, and there is no light wall around it; It's best to knock off the wall brick and make it waterproof again. 3. Cracks appear in the external wall, which causes asbestos in the wall to be wet all the year round. Asbestos in the wall is not easy to dry after absorbing rainwater. Year after year, the inner wall will be soaked with water, moldy and powdery. In this case, consumers should promptly notify the property maintenance, and should not solve it by themselves, so as to avoid danger. When building the house, the construction hole of the external wall was not sealed. Once it rains, the rain will splash into the construction hole, causing the internal wall to regain its moisture, and the wall will appear band-shaped or ring-shaped traces after drying. Because the construction holes are mostly in the flue and exhaust holes, this situation often occurs on the wall near the flue and exhaust holes, and this situation should be reflected to the property in time.
