Maintenance and replacement of household intelligent water meter (water leakage)

Hello, LZ, I'm glad to answer your question.

The water leakage inside the water meter is probably caused by the quality problem of the water meter, but from the picture, it seems that your water meter has been used for some years, which should be caused by too long use. Uneven installation is the fault of the installer.

The valve next to the water meter is an exhaust valve to avoid the rotation of the water meter, which is usually sold in hardware stores.

Smart water meters can be replaced by mechanical water meters, which can be directly removed and replaced. The premise is that your property or water fee management agrees to change. This is a major problem. With this solution, everything will be easy to say.

If the answer is helpful to you, please choose the satisfactory answer under my answer. Thank you.
