Turn off the main switch of the water pipe first, then turn on the faucet in the room until there is no water in the faucet, then turn off all the faucets, and turn off the water inlet switch of the toilet tank, washing machine and other equipment with water storage function. Then turn on the main switch of the water pipe and check whether the water meter moves for 20 minutes, including moving slowly. If it moves, it's leaking, otherwise it's okay.
Another method is to prepare a leak detector for the water pipe. The principle of water pipe side leakage meter is to judge the leakage of specific pipes according to different vibrations by detecting the specific fluctuation of water flow. Using the water pipe leak detector, carefully searching on the ground, this method can basically quickly find the specific location of water pipe leakage.
Causes of water pipe leakage
1. Raw material problem: In fact, the most original problem is that the raw materials used in the pipeline are unqualified. In the process of house decoration, the quality of pipeline materials selected by some owners is not up to standard, and a considerable part of it is because construction workers cut corners and use inferior materials, which leads to pipeline leakage in later use.
2. Pre-planning and design problems: In the construction and design stage, the pipeline will cross the reserved hole size and hole plugging of multiple floors. When the relevant design does not meet the standard, it will lead to displacement or even explosion of the pipeline in the later use process.
3. pipeline aging: with the increase of service time, pipeline will naturally corrode and age.
