Water leakage is a common phenomenon in life. If not solved well, it can bring great trouble and unnecessary property damage to our life. So, is it possible to detect a normal water leak detection? How to detect water leakage? The following is the introduction of Guilin pipe leak detection company.

Can normal water leak detection be detected?

Usually yes, water leaks can be detected as long as the prescribed steps are followed. This type of test uses air pressure to determine if a pipe is leaking. After compressing the pipe, you can determine the pressure value shown on the pressure gauge. If the pressure drops rapidly, the pipe is definitely leaking. If you want to know the exact location of a pipe leak, you can determine it by road sound intensity or audio detection.

How do I detect a leak?

1. General pipe installation must be pressure tested: close the main valve of the pipe, then use a manual pressure machine on the pipe with 8 to 10 kg for half an hour, if the pressure cannot be reduced, the pipe will not leak. If there is a leak, the leak will be very obvious and the pressure will be difficult to maintain for a long time.

2. If it is determined that the pipe is leaking, the pressure gauge will usually come off in a short time. When a slow leak is determined, first stop the pipe from running. After the pipe surface has cooled and the pressure is filled with hot water, close the gate valve on each line on the manifold and observe the pressure gauge to ensure that there is no change in the gauge.

3. Open the gate valve on each circuit and then observe which circuit has a pressure drop. The pressure drop is clearly a circuit leak. After determining the leaking circuit, you can dig the wall to repair the leaking pipe. It is recommended to replace the leaking pipe. Also, the pipes and the pipe slots in the wall should be waterproof to prevent the pipes from leaking again as they age.


4. Using the pipe leak detector, in general, the basic detection method is that, using the pipe leak detector, first connect the host, headphones, sensors. Turn on the switch, put on the headset, place the sensor on the road above the pipe line, place it 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. Therefore, we use the pipe leak detector, a single point in a leak signal is not meaningful, to multi-point repeatedly compared, compared with the sound vibration of the larger place is the leak, of course, we have to consider many other additional factors, such as the direction of the leak breakage mouth, because the pipe is round, if the side of the leak, the larger point may instead be on the side of the road above the pipe, rather than The road above the pipeline, so the location of the pipeline to know, in addition to the tee, bend, water pressure, burial depth, buried layer, etc. will have an impact, the test to take these into account.

4. Finally, we remind you that pipeline leaks are very rare in daily life, the cause of pipeline leaks is basically due to cross-construction damage during the renovation process, the normal pipeline works almost no such problem, the choice of better pipes is also more critical.
