1. First close the main valve of the water inlet of the water pipe. 2. Replace the tube. Cut the broken pipe, connect the new pipe, and put the connector on the other end of the pipe to flush it. 3. Bonding. Apply special glue to the junction and stick it together. 4. Spray water repellent. Spray some penetrating waterproofing agent on the wall or ground where it can be exposed to water, and be sure to spray it all over. 5. Use waterproof paste. After the waterproofing agent is dry, fill it with water-repellent paste. 6. Use plastic steel mud for edge sealing and reinforcement at the corners and edges of the walls.

There are generally two reasons for the leakage of the water pipe under the washbasin in the bathroom. One is that the water pipe is damaged and seepage and the other is the ground seepage. First of all, we need to determine what is the cause of the bathroom leak. The judgment method is as follows:

The method of judging the leakage of the water pipe: Generally, the water leakage of the water pipe is large and continuous; if you pour water into the floor, the hand basin, or the toilet, you can judge that there is no problem with the sewer pipe. If the bathroom has not used water for several days, but still there is water leakage, and the leakage is not alleviated, that is, the problem of the upper water pipe. The method of judging water seepage on the ground: as long as the ground is watered, there will be water leakage downstairs, and when the ground is not using water, there will be no water leakage downstairs.
