What is the detection method of water leakage in heating pipeline? I hope to elaborate.

The water pipes at home are hidden in it. It is not easy to find out its loopholes. You should make some preparations first. 1. Turn off all users (including drinking fountains, water heaters, water valves, etc.). ) Make sure there is no water at home. Observe the water meter at this time. If the water meter is still running, it proves that the water supply pipe is leaking, otherwise it proves that the drainage pipe is leaking. 2. If it is confirmed that the water supply pipe is leaking, then first find out the direction of the water pipe at home. When it's quiet at night, listen along the pipeline, and you can hear the sound of water leakage if it leaks slightly. If the water leakage point is too small to be heard by the ear, you can only ask a professional testing company to detect the water leakage point. Take Guangzhou as an example, you probably need 1500 yuan. 3. There is no conventional method to detect the leakage of drainage pipes, and the professional detection cost is very high. Unless the home decoration is particularly high-grade, it is only recommended to knock all the floors open to find water leaks.
