When to replace a water meter?

Exchange   water meter   is necessary when the device stops working properly or is unable to accurately measure water consumption. Typically, water meters have a warranty period of 2 to 5 years, and their service life is estimated at 15 years. However, there are cases where a water meter replacement may well take place before this time has elapsed. Remember that you, as the owner of the device, are responsible for its technical condition and the accuracy of water consumption measurement.

Replacing water meters can be done in two ways. By replacing the device with a new one or by legalization. The legal basis determining the method of use   water meters   and the conditions for their exchange are the Law on Measures and the Regulation of the Minister of Development and Finance of April 13, 2017 on the legal metrological control of measuring instruments. The water meter as a control device is the basis for calculating fees for water use and the need to pay them in accordance with the tariff. During the metrological inspection, the efficiency of the device is determined and the meter is allowed for further use or requires replacement.   Water meters   should be replaced every 5 years. If the water meter is damaged during use or does not provide data correctly, it should be immediately replaced with a new one with a new verification period. Even if the previous counter has not yet expired.

What are the costs of replacing a water meter?

Water meter replacement prices depend on the choice of device and its type. Replacing a water meter usually takes 30 minutes to an hour and is performed by a qualified plumber. The cost of legalizing the device is not high, usually ranging from PLN 60 to PLN 80. Replacing the device with a new one will be a slightly larger expense, ranging from PLN 70 to PLN 200. The price discrepancy is due to the diversity of many water meter models on the market.

Replacing a water meter costs a bit more than legalization, but it is a much more profitable investment in the long run. New water meters are more precise and do not require frequent calibration, which means lower costs when using water. It is worth remembering that replacing the water meter is also recommended in the case of old devices that may no longer be functional and indicate incorrect water consumption. Therefore, before replacing the water meter, it is worth using the services of specialists who will advise which model will be best for us and ensure professional installation. The costs of replacing a water meter are paid back in a short time and contribute to savings on water bills.

Failure to legalize the water meter at home - legal consequences

The law also specifies the consequences of failure to comply with the obligation to legalize or replace the water meter. Situations subject to penalty are specified in Article 26 of the Law on Measures and apply to both housing communities and private individuals. Replacing a water meter in a single-family house is the responsibility of its owner or user, if it is specified in a separate agreement. In the event of failure to meet the legalization deadline, use of the water meter contrary to its intended purpose, false readings or failure to replace the device despite a detected defect, the legislator provides for penalties in the form of arrest, restriction of liberty or a fine of up to PLN 10,000.
