Who can tell me what to do if the fire hose leaks?

First of all, by closing the main valve of the fire pipe network, confirm the leakage section, observe the ground and confirm the leakage point.

Confirm that the valve can be completely closed. According to our experience, more than 70% domestic valves, especially 1 which has been installed for two years, are hard to die. If you can close the valve, you can confirm the approximate area of water leakage, carefully check the ground state above the pipeline in this area, whether it is sunken or particularly wet, and whether there is stable clear water in the sewer next to it. This water leakage detection method is suitable for the general public, and its technical content is not high, but it is difficult to accurately locate the water leakage point, and the excavation area is large, which is also easy to cause false excavation. Second, use professional monitoring leak detector.

This kind of professional instrument, which is generally equipped only by professional leak detection companies, has the same purpose as listening poles and leak detectors. Experienced leak detectors can accurately locate some leakage points through use. The buried depth is about 1.5 m, and it can also play a role under the condition that the water leakage is not very large.

Third, listen to the sound when you are quiet.

At 2 o'clock in the morning, in the dead of night, when the surroundings are very quiet, walk slowly along the pipeline. If there is a lot of water leakage, there is a certain probability to hear the sound of water leakage.
