Water meters are important "measuring instruments" that are the basis for calculating water rates.
Since the amount of water used measured by the water meter is used for transactions or certifications with customers, standards are set by the "Measurement Law" to ensure proper measurement.
The validity period of the water meter is eight years after passing the test.
In Water Works Bureau City systematically replaces it before the expiration of this certification validity period.
Until May 2028

Precautions after water meter replacement
After replacing the water meter, turbid water or air may come out of the faucet.
Turbid water and air may cause equipment to break down. After replacement, drain the turbid water thoroughly with a faucet and use the equipment.
In addition, in the hot water mixed faucet, please drain on the water side.
Request for improvement of water pipes
Replacement of the water meter in a state where the water pipe before and after the water meter is aging due to corrosion may cause water leakage.
In particular, if water leaks in the pipe space of an apartment, etc., the lower floor may be flooded.
In order to avoid such an accident, we may stop replacing the water meter and ask customers to improve some of the water pipes. We ask for your understanding and cooperation.
In addition, the cost related to the construction of the water supply pipe will be borne by the customer.
