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.

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.
