How to fix leaks in waterproof casing

The waterproof casing in the water room also has a certain role in preventing water from seeping, flowing, and flowing to the lower layer. The "prevention" mentioned here has two aspects. On the one hand, it refers to the improper reasons after the completion of the project, which cause the tap water to flow through the casing to the lower layer during the decoration stage; on the other hand, after the user moves in, unexpected reasons cause the tap water to flow through the casing to the lower layer. Moreover, the former is often more than the latter.

There are two reasons for flowing to the lower layer. One is that the height of the casing is low; the other is that the height is enough, but the casing mouth is not sealed tightly. Therefore, the specification has strict requirements on the height of the casing: in water rooms (kitchens, bathrooms, etc.), the height of the casing should be 50mm higher than the living ground, and the casing of the plastic water supply pipe should be more than 100mm higher than the living ground. And it should be sealed tightly with grease.
