Concealed pipe leak detection method, how to locate the leak

Views: 7     Author: pqwt     Publish Time: 2022-11-09      Origin: PQWT

In the home, the water pipe is a hidden project, it is usually buried underground in the wall and once a problem occurs, it takes a lot of time and effort to fix. A plumbing leak is not a trivial matter, and if a plumbing leak is not dealt with in a timely manner, the leak will become a serious leak and will also leak near the floor or walls. What about water pipe leaks? Today I will explain to you how to do water pipe leaks and what are the causes of water pipe leaks related knowledge, come and learn!

Concealed pipe leak detection method.


1, clear professional master with professional instruments to detect and accurately position on the repair of leaking pipes.


2, when the home concealed water pipe leak, should first close the main valve of the home water pipe. The main valve of the water pipe is the switch of the water pipe before the water meter. Then open all indoor faucets and wait for about 20 minutes to make sure no water comes out of the water pipe, then close all open faucets.

3. Also turn off the water switch of the toilet tank, washing machine and other equipment with water storage function in your house, and then open the main valve. After opening the main valve for 20 minutes, check whether the water meter is moving, even if it is only moving slowly is included.


4, If the water meter is moving, it means that the hidden water pipe is indeed leaking. If the water meter is not moving, then there is no problem. If there is a problem with the water meter, or if there is a very small leak in the plumbing, then it may be difficult to determine if there is a leak. Therefore, when the pipe layout is complete, be sure to perform a water pressure test, usually pressurized to 8 kg for about 20 to 30 minutes.


Method of locating water leakage in concealed pipes


The use of Puch pipe leak detector can be effective in locating. The working principle is that when pressure water is rushed out from the broken mouth of the pipe after the leakage of pressure water pipe, the sound vibration generated by friction with the pipe wall and other additional vibration caused is transmitted above the ground of the pipe, and the instrument is used to detect on the road to find out the leakage point.

pipe leak detection

The basic detection method is, connect the pipe leak detector host, headphones, sensors. Turn on the switch, put on the headset, place the sensor on the road above the pipeline, place it step by step according to the length of the pace, and listen step by step, 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 pipeline leak detector, a single point in the leak signal is not meaningful, to repeatedly compare multiple points, compare 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 on the detection to take these into account.
