The good or bad of the water supply network pipeline greatly affects people's daily life, as in the case of home leaks, usually leaking parts and the usual living water more frequently, in addition to their own investigation, but also need specialized maintenance personnel to detect leaks. Usually no leaks are found at first, usually after a period of time the ground or wall leaks, because water seepage has a time process, the time depends on the size of the leak, there are various reasons for leaks, the most important reason is the use of aging and leakage, usually because of cracked pipes seepage, if the leak is the exposed part is a very good solution, even individuals can complete, some, hidden in the walls or deep water leaks in the ground will need to find a professional repair person to check and investigate, and then install and repair.
(A) Collecting information about the pipe
Collect the drawing information and water consumption information of the pipeline to be tested, and the enterprise arranges for the technical personnel who are familiar with the location of the pipeline to go to the site to point out the plane location, burial depth, material, diameter and other related information of the pipeline.
(B) Regional pipeline environment survey
Fully understand the site situation and make preparations for the next step of leak detection such as construction arrangement and method selection, including pipeline network environment survey, subsidiary equipment survey, water use survey and drainage survey. (If the location of the pipeline is not determined, the pipeline direction and burial depth need to be determined with the help of pipeline meters)
(C) detailed investigation of water leakage and accurate positioning
1, in the work area, daytime hydrants, valves, water meters and open pipes in the area 100% directly listen to the sound waves propagating from the leak point to the pipe structure to find the leak anomaly.
2, in the survey area above the pipe, connect the pipe leak detector good host, headphones, sensors. Turn on the pipeline 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
