Leakage at the wall or plate should be solved in this way: a casing should be installed where the pipeline passes through the floor or wall; no joints should be left between the floor and the wall, if there is, it should be located in a bright place for easy maintenance and replacement; In the room, the upper part should be 30-50 mm higher than the ground, and the lower part should be flush with the shed. When installing the casing, the thickness of the decorative layer should also be considered; the gap between the casing and the water pipe can be filled with asphalt oil hemp wire to prevent dew flow into the lower layer. The solution to the leakage and accumulation of water at the floor drain: the ground leveling should be based on the position of the floor drain, which is at the lowest point of the ground drainage slope; the floor drain should be painted tightly to ensure no leakage around the floor drain; the floor water storage test should be done after the floor drain is installed. Check whether there is leakage around the floor drain; the floor drain grating should be 5 mm below the ground to ensure that the drainage of the floor drain is smooth and the ground is free of water.
