Fire hose network partly buried in the ground, due to the long time buried, coupled with fire pressure and other reasons, will lead to fire hose perforation, leakage, etc., so that the fire pressure can not meet the requirements, due to leakage, some units even shut down the fire hose, buried a huge fire safety hazards.
1, turn off all the water outside the house, observe whether the water meter is moving, moving, indicating a suspected leak. If the meter is not moving, this means there is little to no suspicion of a leak, but you cannot be 100% sure there is no leak (for example, the meter is not moving, but the tenant downstairs reports a leak in their roof) and there may be other factors that are not caused by the pipes; this is because each leak point sounds different, so it is hard to hear the leak worker "leaving the line "- each leak worker has to learn for a year before they can work independently, but experience is also very important; in short, learn more, see more, think more, think more."
2, using professional pipe leak detector
Use the basic detection method of the pipeline leak detector is, connect the host, headphones, sensors. Open the pipe leak detector switch, wear headphones, place the pipeline leak detector sensor on the road above the pipeline, placed step by step according to the length of the pace, step by step listening, the closer to the leak, the stronger the signal, the farther away from the leak the weaker the signal, by comparing the signal strength between different points to achieve the purpose of detecting leaks.
3, infrared methods: infrared thermal imaging detection using photoelectric technology to detect infrared specific wavelength signals of thermal radiation of objects, the signal is converted into images and graphics, which can be used for human visual recognition, infrared scanning measurement in the area of the pipe network, underground leakage occurs, the local territory and the surrounding temperature differences, infrared radiation situation will be different, infrared images will reflect this difference. Leaks cannot be detected using this method, noting that due to subsurface drainage, water conditions may vary depending on other factors.
