What causes water meter to rotate by itself?

If you will keeping away for a long time, you should close the main water valve as much as possible to completely cut off the water source. It is worth reminding that this situation may sometimes be caused by a water pipe leak, so you should pay attention to timely inspection and repair.

Whether the water meter is accurate or not depends largely on the correct installation and usage of water meter.

When installing the water meter, you should pay attention to the following details:

1. Remove hemp, ore and other debris in the pipe to prevent the filter from being blocked, otherwise water meter measurement error will increase and affect the water supply.

2. The water meter should be installed horizontally (except for the vertical water meter, which should be installed horizontally and vertically), the dial should be upward, and the arrow on the case should be consistent with the direction of the water flow.

3. Sufficient straight pipe sections must be left at both ends of the water meter. If you suspect that there is a problem with water meter measurement, do not disassemble it without authorization, but report it to the relevant departments in time and send water meters for inspection in accordance with relevant regulations.

4.Water meters which are used in residents' homes are suggested to replace every 6 years. If water meter is not replaced for a long time, the internal parts will be worn out, which will cause the water meter measurement characteristics to change, making it difficult to ensure its accuracy.
