Why doesn't the water meter turn around?
The pipe is in air and cannot be ruled out. As the pipe network maintenance, disassembly and water meter when water supply is stopped, the air into the pipeline, stay in the pipeline is not common; especially some users network will not change the line, pipeline, tap water before the blocked, and the internal pressure imbalance, causing water to move.
Subsurface leakage. If the water consumption exceeds the normal value of more than doubled, renovation concealed, installation pipe leakage or indoor pipe network underground dark leakage possibility is bigger, especially pay attention to whether the toilet is flowing.
User small flow drop. Many users believe that a drop of water will not measure, but the water pressure caused by dripping water is lower than the pressure of water supply, which leads to pressure fluctuation and the water meter is slightly changed.
