How to find the leaking point of the water pipe in the wall? What should I do if the hidden water pipe leaks at home?

At present, the water pipes for home decoration are generally embedded in the wall, so they are also called concealed water pipes. The most troublesome thing about water pipes is water leakage, which will lead to moldy walls and peeling off walls. How to find the leaking point when the water pipe in the wall leaks? What should I do if the hidden water pipe leaks at home? Come with us to get to know it!

How to find the leaking point when the water pipe in the wall leaks

The first is to find that the water pipe in the wall of the house is leaking. The first time is to find the water inlet valve at home, close the valve and disconnect the water supply source to prevent further water leakage. Check where the leakage point of the concealed water pipe is.

The underground water pipe leaks, so it is not easy to find the leaking point. Because the water pipe in the wall leaks, sometimes the wall base or the wall with tiles is waterproof, and the water leakage of the concealed water pipe may spread to other places with the wall, so sometimes the place where the wall is soaked is not necessarily the place where 100% concealed water pipe leaks.

The most traditional method is to judge the position of water pipe leakage in the wall one by one by pressing the water pipe. Connect the hot and cold water pipes together with hoses to make the hot and cold water enter the pipes in a cycle, then turn off the main switch and close all valves, leaving only one nozzle, and then connect the booster pump. At this time, the pressure pointer is 0.

Then officially start to suppress the water leakage of concealed water pipes, and shake the pressure measuring rod until the pointer of the pressure gauge points between 0.9 and 1.0, which is generally about 6 pressures. Check the pressure value about half an hour. If the pressure drops by less than 0.5 pressure, there is no water leakage. If there is a leak, the pressure will drop a lot.

After finding the leaking point of the water pipe in the wall, it is necessary to replace and repair the leaking pipe. What should I do if the concealed pipe leaks?

1. Replace the damaged pipeline.

First of all, we should dig the wall with hidden water pipe leakage points, and pay attention to the finished product protection of furniture floor when digging. After digging, find the leaking place of the pipeline and clean up the dust dug on the pipeline.

Cut the damaged pipeline, pay attention to it, and then cover it with the interface. Align the new pipeline that needs to be replaced with the interface opening, and pay attention to the alignment. Then, the new pipeline is hot-melted by a hot-melting device. After connection, pay attention to waterproof the pipes and troughs with waterproof glue.

2. Replace the exposed tube.

When the concealed pipe leaks, we must first find out which area of the concealed pipe has problems. If you don't want to cut through the wall floor, you can repair it by changing the exposed pipe. Just disconnect the loose joint between the leaking concealed pipe and the main pipe and reinstall it with the exposed pipe.
