How to detect where the water pipe leaks at home?

1. Check the water meter: Turn off all faucets and water heaters and observe whether the water meter is still running. If the water meter is still running, it means there is water leakage. 2. Check the pressure gauge next to the water meter: If there is a pressure gauge next to the water meter, observe the reading of the pressure gauge. If the reading keeps rising, it means water leakage. 3. Check faucets and drinking fountains: Check all faucets and drinking fountains for signs of water leakage. If there is, it may be the faucet or the water dispenser itself. 4. Check the water pipe joint: check whether there are any signs of water leakage at the water pipe joint, especially at the bend and joint of the water pipe. 5. Use a water leak detector: A water leak detector can help detect the location of water leakage. Place the detector in a place where water may leak. If there is water leakage, the detector will make a sound or flash. 6. Check the wall and ceiling: If the water pipe is in the wall or ceiling, you can judge the location of water leakage by observing whether there are water traces on the wall and ceiling.
