How to detect outdoor buried concealed pipe leaks

Whether it is water pipes or electrical wires, basically choose the way of concealed pipe installation, but one thing is, if there is a problem, such as leakage of water pipes in the concealed pipe, how to detect?

A, how to detect leaks in the concealed pipe


1, how to rank the location and direction of the pipe?

Need to provide the owner of the distribution of the fire network drawings; or led by personnel familiar with the situation of the pipe network; in the case that the owner can not provide the distribution of the fire network drawings, can be found through the distribution of pipe wells, hydrants connected to determine the location of the pipeline direction (fire pipelines are generally distributed in the shape of a ring); in the absence of both of the above, such as metal pipes, you can use a special detection instrument for pipelines PQWT-GX series of underground pipeline detector to find the location of the pipeline to. If it is a plastic and other non-metallic pipelines can products PQWT-PD300 pipe finder


2, water pipes buried in the ground, you can determine whether the water pipes are really leaking through the method of water pressure test. General outdoor pipes come with their own pressure, if the pressure is not enough to use the pressurizer to play to about 10 kg, observe whether the water pressure problem of pressure drop. If the pressure is dropped, and more serious, it means that there is a leak. The next step is to continue the pressure test, if the same pressure drop, it can be judged that there is indeed the phenomenon of water leakage.

3, then you also need to determine the leak point, you can through the special pipe leak detector. For example, by measuring there is a spectrum mode, with sound and screen, to be able to analyze the spectrum according to the signal issued. Accurately determine which part of the water pipe leak problem is the suspected leak point based primarily on its frequency Hertz to determine the strongest signal.


B, how to remedy water pipe leaks


1, the problem of leaking water pipes, there is one of the safest way is to replace the leaking water pipes. Whether it is a joint or a valve, the corresponding replacement can solve the problem. But if the water pipe is still usable and the leak is not particularly serious, we can use a plug or waterproof cement to wipe the leak clean, then add some water, mix some thick, and apply it directly to the leak.


If the leak is not a minor problem, another way is by waterproofing tape. First wipe the surface clean, then apply glue, wrap it with raw material tape, and wrap it around a few times. You can also hit the glue on the leaking area, which can also have the effect of plugging the leak. However, these methods may only solve the current problem, and later, once the water pressure is too high, the problem of leakage will occur, it is best to directly replace the water pipe to be more realistic.


The choice of plumbing is concealed, the later maintenance will be more trouble, which also requires the choice of plumbing materials, including installation must meet the standards, in order to avoid a longer service life of the water pipe, in the use of the process will not appear leakage problems.
