Causes of water meter rotation

1, the internal pipeline behind the water meter is leaking.

It is mainly the leakage of some pipes and toilets that are not easy to find, such as pipes embedded in walls and buried underground. Leaks in the pipes behind these water meters are not easy to find. Even if water is not used, it still leaks, so the water meter will still turn.

2. There is air in the pipeline.

The pipe behind the water meter is relatively long, so it is easy to store air if it is not used for a long time. When the water pressure is high, the air will be compressed and released, and when the water pressure is low, the water flow fluctuation will become larger, and the water meter will open itself.

3, water meter installation is unreasonable

The water meter is too close to the main pipeline, and the pressure fluctuation of the water in the main pipeline directly affects the water meter, which causes the water meter to rotate, so even if there is no water or water leakage at home, the water meter is still rotating.

Installation of water meter

1, the diameter of the water meter should be determined according to the diameter of the installation pipeline, and the installation position should avoid exposure to sunlight, immersion, freezing and pollution, which is convenient for disassembly and swiping.

2. The water meter should be installed horizontally (with the display facing up).

3. Before the installation of new clothes, sand, hemp and other sundries in the pipeline should be removed to avoid water meter failure.

4. The arrow direction displayed by the water meter should be consistent with the direction of water flow in the pipeline.

5. If the water meter is installed at the inlet end of the boiler, it is best to install a check valve at the outlet of the water meter to prevent the boiler hot water and steam from flowing back and damaging the internal parts of the water meter.
