The service life of water meters according to the law, the rules for operating metering devices and the procedure for their replacement. Who should change water meters in an apartment?

What are they?

Using a flow meter implies independent monitoring of deadlines:

Warranty period. During this time, you can replace or repair a faulty device free of charge.
For meters in apartments, the period is 1.5 years from the date of use, provided the standard diameter is 8-50 and the throughput is not higher than 202.5 thousand cubic meters.
Interverification period . On average, every 4 years for DHW and 6 years for cold water, it is necessary to test the device, check the accuracy of the readings, and the correctness of the data reflection.
Operating time. The time period at the end of which the meter must be replaced is specified in the product data sheet. Can be used for decades.

Law on replacing the water meter, is it necessary to change it in 2020

Everyone who uses hot/cold water meters has long been convinced that this approach allows for good savings. The population is guided by the principle that you need to pay for what you use - this is the most correct approach.

The government has adopted several acts that regulate the means and methods of measuring water supply. Federal Law No. 102 of June 26, 2008 - this law governs the provision of uniform measuring instruments. The document defines the need to check devices according to metrology requirements.

The purpose of the act is to protect the rights of citizens, society and the state from the negative impact of incorrect measurements. This document also establishes a period after which the inspection must be carried out. During this period, the device operates unhindered, taking into account the supply of cold/hot water. It is allowed to install only those meters that are approved by the register of measuring instruments of the State Standard of the Russian Federation.

Federal Law No. 261 dated November 23, 2009. This law “On energy saving and increasing energy efficiency and on introducing amendments to certain legislative acts of the Russian Federation” obliges all water utility subscribers in apartment buildings to install water meters without fail. To do this, you need to draw up an agreement with the water utility, and 180 days are given for all installation procedures.

Mandatory installation of a meter provides the following advantages:

Economical management of resources.
The measuring tool allows you to determine possible losses.

Decree of the Government of the Russian Federation No. 354 dated May 6, 2011. This document explains the features of payment for the use of water and other services in apartment buildings, as well as the rules for the provision of utility services. The resolution clearly defines the concept of the amounts payable in the presence of a meter, as well as in its absence.

The device for measuring the amount of water supplied is an accurate measuring instrument. The latter may simply work together over time and show a false expense for which you may overpay.

Neither the water utility nor the end client in your person will like this situation. What is the reason for the loss of measurement accuracy and how large is the error, and in what direction?

Hot/cold water has different effects on metering devices. Hot water contains chemical additives that, in tandem with high temperature, aggressively affect the parts and mechanisms of the measuring instrument. Therefore, checks of such devices need to be done more often.

The result of such a test can show complete serviceability, while failed equipment should be repaired or replaced.

The inter-inspection period of the installed measuring device in the hot water supply system is 4 years. As for cold water supply, meters are checked every 6 years. The deadlines do not indicate that replacement will be required. The water meter must be replaced when a breakdown is detected and the recording occurs with errors.

The average service life of the meter is 12 years. From this we can easily conclude that one copy can last 6 years, and the other – all 18. It is important to note that you need to start the meter checking procedure in advance, and not on the last day of the end of the checking interval. It is best to do this one to one and a half months in advance.

If the inspection deadline is approaching, the supplier may also notify you by written notice.

The check is performed on specialized equipment, but not everyone knows that the same check can actually be done right on site. To carry out the procedure, the subscriber can choose an organization that has the right to perform this type of work.

before starting work, it is necessary to turn off the water with prior approval from the housing office;
open access to water supply pipes;
the condition of the pipes must be satisfactory;
Shut-off units should be provided in the apartment to locally shut off the water.

The check is performed using several methods:

If you use the services of a specialized company, call a home plumber to dismantle the water meter. The removed meter will be put into operation and a document on seizure will be drawn up, which indicates the serial number and brand of the device. Keep the documents for the counter with you - your passport and your passport as a citizen of the Russian Federation.

The verification procedure is carried out using a calibration unit, which verifies the readings as accurately as possible. The duration of the check ranges from several hours to several days. When you receive the water meter back, you will be given the following documents:

Meter installation agreement.
Certificate of completed work.
Document confirming the commissioning of the water meter.
Certificate for cold water supply meter.
Passport for hot water supply water meter.
Certificates for equipment.
Maintenance contract.

If after checking it turns out that the water meter is broken, it will need to be replaced. A working device is installed in the same place, all changes are documented. The new water meter can be used until the next check comes.

When choosing a company to check the meter, make sure that it is specialized and has the appropriate permits for such activities. Upon arrival of specialists, all necessary water meter tests are performed. This approach is the most convenient - you save a lot of time. Representatives of the equipment testing company independently contact the water utility, which, in turn, eliminates the need for verification. You, as a client, receive a document about the date and results of the meter tests.

This on-site testing approach has its drawbacks. During the test, up to 250 liters of water are passed through the device, for which you will need to pay. If a malfunction is detected, you will not be able to repair or adjust the water meter on site - dismantling will still be required.

If the check was not completed on time: what to do

If there is a water meter inspection report, its owner is obliged to ensure that he does not miss the deadline for the next procedure.

An incorrectly functioning meter is considered unusable, and payment based on these readings is impossible. Thus, in such a situation, you will pay for water utility services according to average standards. In simple words, it’s as if you don’t have a meter installed that takes into account the number of people living in the apartment.

These numbers will be much higher than what you paid if you had a properly working meter.

To summarize, we note that meters need to be checked once every 6 years for cold water supply, and once every 4 years for hot water. The procedure is paid, and the maximum cost for the service does not exceed one thousand rubles. There are only three ways to check:

Inspection by the water utility with dismantling of the water meter.
Self-diagnosis on site with the involvement of a specialized organization that has all the permits to carry out such work.
Dismantling and inspection by the same specialized company on site, only in a shorter period of time than diagnostics at the water utility.

The last two methods allow you to quickly complete the procedure, and the company’s specialists contact suppliers and notify them of the completed check.

Do not ignore the end of the interval and the need to test the water meter. By doing this, you can only overpay for the water supply services received at prices that are considered average.

Checking the meter does not mean that it is time to change it; perhaps everything is in order or the operation of the device needs to be slightly adjusted.

In case of failure, the water meter must be replaced. As a result, be attentive to the measuring instruments not only for water, but also for all other services, and you will save a lot of money. All payments are made only for what you used.

Hot and cold water meters allow you to accurately control water consumption. Metering devices built into hot and cold water supply pipes constantly “read” the volumes of water passing through them. But water meters are ordinary mechanical or electronic devices.

The constant operation of device elements will sooner or later lead to their wear and failure; a change in the performance of components can affect the display of water consumption readings, both up and down. In such situations, the inevitable fact becomes the need to replace metering devices.

The procedure for replacing water meters is strictly regulated by law

The water meter has a certain effective service life. Hot and cold water meters must be installed in each apartment on the appropriate water supply lines. In most situations, each of us uses water quite often. Over the years of operation, the elements of the device wear out and can cause breakdowns. Any change in the operation of the device may cause incorrect data transmission.

Each meter manufacturer conducts laboratory tests, the results of which determine the approximate period of effective operation of the device. According to most experts, the real service life of high-quality devices under optimal conditions of use reaches about 15-20 years.

But it is worth understanding that our apartments do not have optimal conditions - the presence of impurities and foreign elements in the water, as well as constant pressure drops, accelerate the wear of appliance elements and reduce the period of effective operation. For this reason, a so-called inter-verification period has been established - the period between production and testing of the device’s functionality. It amounts to:

for hot water meters – 4 years;
for cold water meters – 6 years.

The difference in terms is due to the nature of use - hot water is a more aggressive environment. In addition, do not forget that hot water is expensive, and this circumstance requires more careful control.

Do you need to change your water meters according to the law? The main regulatory act, which lays the foundations for regulating issues related to metering devices, is Federal Law No. 102 of June 26, 2008. The law establishes key requirements for monitoring the use of resources. If a device is not assigned a registration number, it cannot be considered operational and cannot be used to monitor water consumption.

Each water meter has its own registration number

After the inter-verification period, the meters must be verified. The procedure for checking meters involves determining, using high-precision weighing equipment, errors in transmitting data on water volumes. All actions are carried out in the apartment, without dismantling the equipment, and take several tens of minutes.

After carrying out the verification procedure, a specialist from an organization that has the appropriate accreditation fills out a report and makes appropriate entries in the instrument passports about the verification.

If the verified water meter is in working order, it will work until the end of the next verification period. After the next period, verification will also be carried out, and so on. That is, the meter does not need to be changed after the verification period has expired; it must be replaced only if faults are detected. In practice, a high-quality meter can complete two verification periods without problems.

If we consider the question of how profitable it is to verify or replace water meters, then the first option looks more attractive in all respects:

no need to dismantle the device;
the cost of verification is lower than the price for purchasing a new meter and installing it.

When should the meter be changed? Replacement is required in the following cases:

The device is faulty.
During verification, critical deviations in the transmitted readings were identified, requiring replacement or repair of the device.

A malfunction of the water meter is determined by the following signs:

a sharp change in monthly water consumption readings that has no objective reasons;
The motion indicator or flow dial does not function.

But only a specialist from an authorized company can officially determine the malfunction. To do this, it is necessary to carry out verification within the established time frame. Don't hesitate to replace it if your meter is faulty.

If you do not change it in time, sooner or later the controlling authority will identify the malfunction and calculate consumption according to the general standard until the serviceability can be confirmed. Such recalculation may affect several years and result in a significant amount. It is better to spend a little money on purchasing and installing a meter.

Self-installation of a water meter is not rational

You will still have to notify the management company about the replacement and invite a specialist to check the correctness of the procedures performed, as well as to seal it.
Installation by a specialist management or specialized company will allow you to obtain guarantees and avoid liability in the event of violations or breakdowns.

The rules for replacing a water meter imply the following sequence of actions:

Submitting an application to the management company to replace the meter.
Coordination of the arrival of the master.
Purchase of necessary equipment.
The technician visits the apartment and carries out the procedure for replacing the device.
Installation of seals and commissioning. The replacement technician must provide all necessary documentation.

To facilitate the procedure for replacing and checking metering devices, general requirements are imposed on their installation:

Meters must be accessible.
Pipes must be maintained in good condition.
Valve and ball equipment must tightly shut off the water.
In a private house, replacement of meters is carried out on a general basis.

Thus, replacement of devices should be carried out only in case of malfunctions in its operation. No one can force you to change the metering device, but if malfunctions are detected, payment will be made according to the standards, so it is better to monitor the performance of the control devices, check them in a timely manner and change them if necessary.

This is interesting: How to calculate water using a meter? 2020

Many Russians have meters for cold and hot water in their apartments. The financial issue for the purchase and installation of equipment has finally been resolved. And it seems that savings on utility bills have even begun to manifest themselves. But a new thunder struck - putting forward a demand to replace or check water meters from private companies. Moreover, the replacement in this case looks like a planned or forced one.

What this is, whether the actions of the management company are legal and whether replacement of water meters is actually necessary, we will discuss below.

If you are overwhelmed with calls from various companies demanding that you URGENTLY change your water meter, know that such calls are illegal and there is NO need to take any action with your meters.

Firstly, representatives of the ERC or DEZ never call their clients. They simply receive data from meters between the 23rd and 26th of each month and issue a water bill on this basis. If the data is not received within the specified period, the invoice will be generated according to the average rates per person. In addition, representatives of these same organizations do not remind you that it is time to check the water meter. The user should be aware of this. Thus, according to the law, the previously established calibration intervals for meters for hot (4 years) and cold (6 years) water have been canceled since 2012. Now water meters need to be checked as needed, that is, if the user suspects that the device is counting incorrectly. And only in this case, having a verification certificate in hand, you need to contact the Criminal Code or the Economic Desk to carry out the procedure for replacing the meter.

Important: it is worth knowing that according to the technical data sheet, the estimated service life of the device is 12 years. And it is likely that your meter will completely expire without a single check.

Secondly, frequent calls from various companies are pure fraud, which, unfortunately, still affects vulnerable segments of the population - gullible people, pensioners, or those who simply do not know the laws.

Important: mandatory replacement of the meter is illegal. No matter who it is carried out by. This is simply a scam of the consumer out of money.

Thirdly, if you are wondering where scammers get your phone number, then know: all data is leaked from the DEZ or ERC database. The answer to the question “why” is obvious.
Moreover, it is always worth remembering that a metering device is a fairly simple mechanism, at the heart of which lies an impeller and a magnet with a dial. That is, there is simply nothing special to break there. And even if an arrogant employee of a private company somehow convinced you of the advisability of carrying out inter-interval verification and is now trying to tell you that the device urgently requires replacement (even though in your opinion he thinks it is correct), do not give in to scammers. Change the device only if you notice real discrepancies in the readings and actual water consumption.

Meters for cold and hot water are subject to mandatory replacement only if they are found to be inoperative as a result of verification. In this case, the owner is given a certificate of inspection and recognition of the mechanism as unfit for use. Here are the reasons for the failure:

Natural wear and tear;
Clogged pipes and build-up on the impeller;
Depressurization of the meter housing due to mechanical impact or unauthorized interference in its operation.

With the act in hand, you should contact the DEZ or management company and write an application to replace the water meter. In this case, you must buy a new device at your own expense. When the technician changes the meter and seals it, he will issue a certificate of putting the new device into operation. All that remains is to take the papers with zero water meter readings and the report on the work performed to your management company or to the Unified Center.

Important: if during the test the meter is found to be working, the device must be replaced. And the owner is issued a certificate stating that the mechanism is fully operational and subject to further use.

There are several ways to check the functionality of accounting equipment:

Houses without dismantling with the help of a foreman invited from the DEZ or Housing Office. He will connect a special device to the mixer and check that the water used is recorded correctly. You will receive a certificate of suitability of the device.
Houses without dismantling, by inviting a private craftsman from a private company. The same actions will be carried out. But they will be considered legal only if and when the company or craftsman has a license to carry out such work.
Take the device to the metrological service yourself. You just need to remove it first after drawing up a report on the integrity of the seal and the device body. As a rule, a piece of pipe can be placed in place of the removed meter while the water meter is being checked. In this case, the management company will recalculate in accordance with average water consumption standards.

By the way, the first and last methods of checking the device are considered the most profitable in terms of saving the family budget.

But don't relax completely. There is also a so-called planned replacement of metering devices for cold and hot water. This is carried out if a law has been adopted to replace the water meter with a more advanced model. But there is simply no such law.

In the second case, a planned replacement of the meter occurs precisely when the device malfunctions and this is documented after checking the mechanism.

In other cases, any arrogant and harsh demands to replace or check water meters can be considered pure fraud and punishable by law.

Remember: only you have the right to decide whether you need to check the meter and change it or not.

Important: if you are afraid that the hot or cold water meter is really faulty and you will have to change it after checking, then in this case you can save money on checking and just buy a new mechanism right away. Notify the DEZ about your desire to replace the device and wait for a technician to complete the work.

Each Russian citizen consumes different amounts of water, gas and electricity, and this may be much less than provided by the standard. Metering devices will help control resource consumption and save utility costs.

In accordance with clause 1 of the Federal Law of December 27, 2018 No. 522-FZ “On amendments to certain legislative acts of the Russian Federation in connection with the development of electrical energy (power) metering systems in the Russian Federation” (hereinafter referred to as Law No. 522-FZ), innovations are provided related to the operation and replacement of electricity metering devices. From July 1, 2020, the responsibility for installing, verifying and replacing devices is transferred from consumers to resource providers and network organizations.

The consumer of services will only retain the obligation to maintain the integrity of the metering device.

When replacing meters in 2020, users of electricity services must be guided by the following standards:

In accordance with the requirements of current legislation, the responsibility for ensuring the uninterrupted operation of electricity meters, their replacement and repair lies with management companies or apartment owners if the meter is located indoors or within the boundaries of the user’s land plot.

The management company is obliged to enter into an agreement with the owners of the premises, the clauses of which will indicate the conditions for the use, installation and replacement of electricity meters. Metering devices for municipal apartments and meters located on staircase landings must be installed, maintained and replaced at the expense of management organizations.

Metering devices should be changed if:

All devices are being replaced on a scheduled basis;
the counter is faulty, records inaccurate results;
The service life of the old device has expired;
the state verification period has expired.

The installation of a new device can be initiated not only by the consumer, but also by an energy-saving company, which sends a written notice of replacement to the homeowner.

According to the new Law No. 522-FZ, a state program is provided, according to which metering devices will be replaced free of charge with new meters with additional capabilities at the expense of government agencies.

If you want to find out how to solve your particular problem, please contact us through the online consultant form or call :

The replacement schedule will be developed by the relevant organizations with mandatory warning to service consumers. New meters will be the property of the energy supplier.

Replacement will be made as the service life of the old meters is exhausted.

The legal provisions obliging the installation of gas meters have not changed in 2020. In accordance with Art. 13 of the Federal Law of November 23, 2009 No. 261-FZ “On energy saving and increasing energy efficiency and on introducing amendments to certain legislative acts of the Russian Federation” (hereinafter referred to as Law No. 261-FZ), gas suppliers must take actions to equip the facilities under their control control, gas consumption metering devices in a timely manner.

The requirements of Law No. 261-FZ for the installation of devices by owners do not apply to owners of emergency and dilapidated facilities, as well as if gas consumption for users is less than two cubic meters per hour, for example, if a gas stove is installed in the room. In such cases, organizations that supply natural gas to consumers are required to operate, install and replace gas meters.

In this case, the owner’s consent is not required and the gas meter can be installed forcibly.

If the owner of the living space wants to install a gas consumption meter, or this needs to be done by force, then the installation procedure and all operating costs will be borne by the owner himself . In accordance with Art. 158 of the Housing Code of the Russian Federation, the owner bears all expenses for maintaining the residential premises.

There are no innovations in legislation in 2020. In accordance with Art. 13 of Law No. 261-FZ, the responsibility for equipping water metering devices and putting them into operation lies with the owners of residential premises. They also bear the costs of purchase and installation. Owners of municipal housing have meters installed free of charge.

The procedure for using water is determined by Decree of the Government of the Russian Federation of September 14, 2013 No. 776. Based on Decrees of the Government of the Russian Federation dated May 23, 2006 No. 306, dated May 6, 2011 No. 354, tariffs are established and categories of beneficiaries are determined.

The coefficient for payment according to the standard in 2020 is 1.5, that is, those who did not install it pay 50% more for water consumption.

After 4 years of service for the meter for hot water and 6 years for cold water, the devices must be verified. If the specialist does not detect any violations, then you can continue to use the equipment until the next inspection interval. The average service life of meters is 12 years.

With the removal of the metering device , dismantling and further readings are taken, the equipment is examined in the laboratory, and a verification report is drawn up.
Without removing the metering device - research and tests of the water meter are carried out on site, and upon completion a report is drawn up.

The owners and occupiers of the premises themselves must keep track of when the time has come for the inspection. To avoid paying for services according to the standard due to the expiration of the period for conducting equipment testing, the verification results should be provided to the managing organization.

The legislative framework

The legal recommended service life of a vane flow meter is 12 years. This is stated in GOST R 50601-93 along with the standards and requirements for this equipment. Warranty service for impeller products is provided for 18 months. For other devices, the service life is set by the manufacturer .

Resolution No. 354 describes the rules for providing the population with public utilities, the rights of consumers, and their responsibilities, including:

Repair or replacement of the meter when a breakdown is detected or the service life has expired.
Carrying out verifications within the time established by law and by the manufacturer.
Opening access to inspection staff for verification.

Attention. Some manufacturers make meters not according to the state standard, but according to specifications - their own technical conditions. They may not contain requirements that are inconvenient for the manufacturer, so this should be clarified before purchasing.

Differences between metering devices

Since the main task of metering devices is to obtain the most accurate information about the amount of resource consumed, it is extremely important that they work properly. Any deviation from the norm already indicates that the information provided is incorrect, which means that the owner, in case of a late response to this, has the right to be required by law to pay tariffs with increasing coefficients. Considering that, as a rule, equipment is installed, on the contrary, to save on paying for this utility service, this is a very unpleasant moment. Moreover, tariffs are regularly increased, and the payment amount is calculated based on the number of registered people.

You need to know that absolutely all metering devices are subject to scheduled inspections and have a limited service life. The hot water meter is checked more often than the cold water meter. This is due to the fact that mechanical parts of equipment in contact with high temperatures, to which chemical additives are added, are susceptible to aggressive influence and quickly become unusable, requiring repair or complete replacement. The frequency of their inspection is, accordingly, less than that of similar equipment that calculates cold water consumption.

Period of use of the cold water supply meter

Devices that meet state standards can operate for 16 years.

The duration of operation directly depends on factors:

build quality;
quality of materials;
accuracy of adherence to technology;
conditions under which the device will be used.

Attention! Professionals recommend changing devices before the second verification.

Where is the time of use stated?

The date of manufacture, factory testing and the time after which the device should be returned to authorized organizations for accuracy control can be found in the technical data sheet of the device. The rules for operating the equipment and other necessary data are also described there.

Reference. You can restore the technical documentation of sealed equipment by contacting the manufacturer or getting a copy from the management company or the housing office. Unsealed equipment will have to be replaced if the manufacturer refuses to issue a registration certificate.

How to verify a water meter?

When the verification deadline approaches, the homeowner needs to call one of the accredited companies and agree on a date and time for the diagnosis.
There is no point in delaying the deadlines: at the end of the verification period, the meter readings are considered invalid and the payment for water consumption will be calculated according to the average standard, and this is financially unprofitable, first of all, for the homeowner. This accrual procedure is regulated by PP No. 354 of 05/06/2011, so it will not be possible to challenge the increase in payment .

The verification procedure itself takes no more than 20 minutes. The diagnostic specialist uses a special device to connect the meter to the water supply and pump a certain amount of water through it. Next, the readings are compared and the level of error of the meter is assessed.

The verification results are recorded in a report confirming the serviceability or malfunction of the meter . The received document must be submitted to the water utility to calculate payment for water in accordance with the meter data, which will now be considered correct until the next verification. If the water meter is faulty, you need to install a new device.

Previously, for metrological verification of the meter, it was necessary to remove the device and carry out testing in the laboratory, which took several days. In 2020, this method is almost never used by any company.

However, when choosing a specialized testing company, check how the diagnostics are carried out - with or without dismantling the device.

List of breakdowns leading to forced replacement

You can determine if the water meter is broken visually - incorrect reflection of the actual volume, periodic or complete stops in the movement of the dial.

List of faults:

violation of tightness, accompanied by sweating of the glass;
incorrect installation, misalignment;
detection of a manufacturing defect;
high water temperature, leading to melting of plastic parts;
pressure exceeding normal;
clogged pipes;
unauthorized intervention by unauthorized persons.

Detection of a breakdown leads to a forced replacement of the water meter.

Actions after the end of service life

In the last month of operation, the device must be replaced with a new one, regardless of the results of the last verification. Users who miss the deadline will be forced to pay for the consumed resource according to the standards established in the region.

You should determine the service life yourself, based on the data in the technical passport.

In the last month of operation, the following actions should be performed:

Submit an application in the prescribed form to the management company. Additionally, provide proof of ownership.
Enter into an agreement with a company that installs water meters.
Buy a device of the established type, check the expiration date.
Carry out correct installation and keep the certificate of completed work.
Seal by inviting an employee of the management company.

Sample application to the management company:

Approved dates

Before talking about what time meters really need to be changed, it is necessary to take into account the intervals for checking water meters. For example, equipment for hot water is checked once every four years, for cold water - once every six years. If, as a result of the inspection, no faults were identified or they were eliminated, there is no need to change the water meters. They continue to serve either until the next inspection or until their useful life expires.

It is worth noting that the service life of water metering devices is not the same for all models. On average, they last twelve years, but one model may be designed for only six years, and another for eighteen. You can find out about the operating time when purchasing new equipment, as well as by looking at the technical passport. It must indicate this period, that is, an indicator of when this model needs to be changed if a breakdown or other damage has not occurred earlier.

The owner of the real estate must monitor the expiration of the service life. You need to deal with replacement issues not when the device is no longer suitable, but at least a month before, or even a month and a half before. As for scheduled inspections every few years, they also cannot be skipped, but they are usually reminded of them with written notices that come along with payment receipts.

Cold water

Non-volatile tachometer-type water meters are suitable for home use. A mechanical structure designed for temperatures up to +30 °C is marked in blue - a plastic case of this color is made or an outline strip is applied to the scale. Universal counters do not have color characteristics; they can withstand heating up to +70 °C.

Hot water

Water meters for coolant are made of heat-resistant materials.

Allowed to install:

universal wing structures;
appliances for hot water, they operate up to + 130 °C;
water meters with temperature sensors, their service life is from 8 to 15 years.
