Procedure and rules for installing water meters: installation and sealing rules
To control water consumption, it is imperative to include devices for measuring water consumption in the water supply system, namely, install water meters with parameters that comply with current standards.
Agree that such a device will not only allow you to control real consumption and pay only for used water, but will also teach you how to save this resource.
But first you need to buy it and, following the rules for installing water meters, connect it correctly. We will look at how to do this in detail in the article. Here are the basic installation rules with visual photos of the individual stages of installing the device.
As a supplement to the main material of our article, we have selected video recommendations for self-installation of meters. After all, metering devices can be installed with your own hands, but with the permission of the services performing the sealing.

Types of meters and their features
Devices for recording water consumption in a specific residential building are installed on the communication networks of apartments and houses connected to centralized water supply systems.
Installation rules with a number of requirements and commissioning procedures have been developed for management companies. Although the installation, if desired, can be done manually.
At choosing water meters For tapping into water mains, a number of significant factors should be taken into account:
- condition of pipelines;
- the presence of foreign inclusions in the water: fine suspended matter and larger insoluble particles;
- material aspect — financial capabilities of apartment/house owners;
- nature of use of devices, stationary temperature of the working environment.
Depending on the sources of energy supply, two groups of water flow meters can be distinguished.
These are volatile, i.e. those requiring electricity to operate, and non-volatile, functioning due to the action of natural mechanical processes.
Energy-dependent ones include electromagnetic, ultrasonic, and vortex. Their operating principle, based on the use of physical phenomena, is the basis of their name.
The list of power-independent devices includes tacheometric varieties.
There is a division according to design into separate and compact types.
Water meters are divided according to the number of serviced water pipes into multi-channel, single-channel, and two-channel models.
Type #1 - induction (electromagnetic) meters
The device is not cheap, its service life is more than ten years, the operation of the device is based on the ability of water to conduct electricity. Used when there are no foreign inclusions in the water (scale, rust, etc.).
The quality of water and pipelines make it difficult to use in everyday life.
Such water meters are most widely used for monitoring water flows in the pharmaceutical, food, and brewing industries and for water metering of wastewater flows.
Type #2 - ultrasonic meters
More expensive than electromagnetic ones, but has greater accuracy and service life (more than 15 years). The operating principle is based on comparing the propagation of ultrasound speed “with” and “against” the flow. Used for clean water and pipes, not widely used.
There are two types of ultrasonic water meters: Doppler and time-pulse.According to the installation method, they are divided into: those installed outside the water pipe (Clamp on) and in direct contact with water or mortise (Insertion).
The main area of application is for recording the water consumption of industrial enterprises and the amount of waste water discharge.
Type #3 - vortex counters
The operating principle of vortex metering devices is to detect vortices arising behind a “blimp body of a special shape” placed in the flow.
For example, if a certain object (a rod of a specific configuration) is lowered into the flow of the measured medium, then the resulting frequency of vortices on it, or as it is otherwise called the so-called “Karman track,” will become proportional to the flow speed, and therefore to the volumetric flow rate.
Simply put, vortex counters record the number of oscillations caused by the collision of a flowing medium with a relative obstacle, and convert this number into liters passing through the pipe.
Such devices have become widespread in operations for adjusting and monitoring technical processes. Their use is irrational in domestic conditions.
Type #4 - non-volatile (tacheometric) meters
Inexpensive meters with a service life of about five years, designed for equipping domestic and industrial water supply networks.
Among them there are modifications produced for operation in conditions of old water supply and questionable water quality aspects.
According to the location of the axis of rotation, they are divided into:
- winged — the axis is perpendicular to the flow;
- turbine - the axis is parallel to the flow.
The operating principle is based on recording the number of movements of the impeller or turbine. When water masses move, the main working parts of the devices rotate, which in turn sets the mechanical counter in motion.
In diameter winged water meters no more than 40mm. They can keep track of water up to 15 cubic meters per hour. Turbine devices have a diameter of 50 to 100 mm; unlike previous ones, they have a much larger reading of passing water.
The accuracy of the readings is low, but the reliable design has been proven by many years of excellent work in water supply systems (apartments, houses, offices, etc.), which makes them the most popular.
According to the operating temperature range, meters can be for hot water (operating values t° up to +130 °C), for cold water (t° up to +30 °C) and universal (t° up to +90 °C).
They can be distinguished by color and nomenclature designation. Usually produced for hot water SGV Red. To calculate the cold water consumption, make SHV of blue color. There are also universal options - SPM orange color.
According to the principle of operation, water meters are divided into:
- Single jet. Water flows into the impeller or turbine in a single stream.
- Multi-jet. The water flow is divided into separate jets, used for large diameters over 40mm.
Based on the method of installing reading mechanisms, all types of mechanical devices can be divided into dry and wet. In wet ones, the counting mechanism stands in water, while in dry ones it is separated by a plate.
Most apartment owners and homeowners whose homes are connected to centralized networks choose tacheometric water meters.
I am attracted by the availability of mechanical devices both in terms of price and availability. They can be found in almost any plumbing store. Tacheometric types of meters are easy to install and operate.
You may also find the information discussed in our other article useful, about top ten counters, popular among buyers.
What do you need to prepare before installation?
At choosing the appropriate meter type It is advisable to take into account not only the characteristics declared by the manufacturer, but also real reviews left by users who managed to buy and install a specific model.
After choosing a metering device, you need to make sure that the delivery package contains everything necessary to install the metering unit.
It is also worth deciding on the place where the meter will be installed directly. For normal operation of the flow meter, it is necessary to have natural or artificial lighting, an air temperature of at least 5 °C, and accessible space for maintenance.
In this case, you need to adhere to some rules:
- It is necessary to prepare the place for the upcoming work. It seems like a small thing, but working when something is in the way is extremely inconvenient and will take more time and effort.
- If the pipes are not suitable for use, care must be taken to replace them.
- The meter kit should include: a coarse filter, a check valve, cap nuts (American) and the meter itself. If something is missing, you must buy it in addition, otherwise the meter will not be sealed.
- When installing the meter yourself, make sure there are gaskets (rubber or paronite), plumbing sealants (tow, Fum ribbon);
- You should stock up on tools for working with pipes: scissors for cutting plastic pipes, an iron for forming joints, a set of keys, etc.
Let's take a closer look at each detail of the future unit and why it is needed. The shut-off valve is used to regulate the flow of water. Usually used Ball Valves.
They are easy to use, but quickly fail in an intermediate state between “closed” and “open”.
The coarse filter is used to prevent large insoluble particles such as grains of sand contained in water from entering the device mechanism.
Filters for mechanical flow purification come in two types: straight and oblique (only oblique is used to install the meter).
The check valve serves mainly to prevent the meter readings from unwinding, and also, in the absence of analysis, prevents water from flowing in the opposite direction.
If necessary, American women will help dismantle the water meter without consequences for the water supply system.
You can also install other elements in the water metering unit. They are optional, but will be very useful.
This is a shut-off valve after the check valve (so that when removing the meter, water does not drain onto the floor), a pressure reducer is installed after the coarse filter, which stabilizes the pressure in the system and extends the life of household appliances.
Now the water meter itself:
- When purchasing, you must check the identity of the numbers in your passport and their analogues stamped on the water meter.
- You need to make sure that there is a certificate and a stamp in your passport with the date of factory verification.
- And it’s a good idea to take a sales receipt from the store and issue a guarantee; in the event of a malfunction, if there is a certificate and a receipt, the meter must be replaced.
Try to purchase a water meter in a specialized store rather than on the market; it will be easier to replace it if it breaks.
After making sure that you have everything you need, you can begin installing the water meter.
Water meter installation technology
You can install a water meter yourself, or you can seek help from specialized institutions, a management company, or a structural department of a water utility.
When choosing a company, make sure it has a license and provides a warranty period of service, read the reviews.
If you do not trust the work to others and are confident in your abilities, then you can install the meter yourself, just first consult with specialists from the water utility to see if they will allow you to install the meter yourself; usually it is not prohibited.
Regardless of who will install the water meter, the procedure for installing a water meter will not change:
- Before starting installation, you must turn off the water in the riser. You should submit an application to the management company or, if you have a shut-off valve, close it yourself.
- It is necessary to determine the installation diagram of the unit and its position (vertical or horizontal).
- Then you need to connect the shut-off valve and the coarse filter (without plumbing winding) in such a way that the filter pipe with the mesh is directed to the bottom, determine the number of turns when twisting.
- Now you need to remove the filter again and completely assemble the entire assembly, taking into account the number of turns, using a winding.
All threaded connections are carefully wrapped with sealing tape and treated with plumbing mastic.
When assembling, pay attention to the water meter; there are arrow marks on it.
The direction of the arrows must coincide with the direction of water flow through the device, otherwise the operation of the installed meter will be incorrect, which is why the water utility representative will not accept such work.
It is important to ensure the required position of each element. In the direction of water flow, it looks like this: shut-off valve, coarse filter, water meter, check valve.
The next stage is preparing the pipeline for installation of the system.This is a rather pedantic process, since the length of the assembled unit must match the length of the section on the existing pipeline with a minimum error.
Of course, you can use flexible eyeliner, but it doesn’t look aesthetically pleasing.
Before cutting out the pipe, it is advisable to place a basin or other container into which the remaining water in the system will be drained.
Depending on the pipes it will be necessary cut thread in the case of metal pipes or use fitting And propylene soldering iron in the case of polypropylene pipes.
You may also find information about the rules useful connections between plastic pipes and metal pipes, which is given in our other article.
The final stage is the insertion of a water meter into the water supply system. We install the assembly we have assembled into the prepared system, and we need to seal all threaded connections using linen liner or Fum tape.
When tightening threaded connections, do not apply great force, as this can lead to the formation of microcracks and subsequent leakage. If everything is done correctly, then there will be no leaks when water is supplied, you can proceed to installing the seal.
Seal installation and technical documentation
After you have installed the metering unit and checked that it is working properly, the question arises, how to properly seal the water meter? You should find out who is doing this, whether it is possible to put a filling yourself.
You should entrust the installation of the seal to specially trained people: representatives of the water utility or the management company. To do this, you must submit an application to receive a meter.
Do not hesitate to apply, despite the installed meter, water consumption will still be determined at the maximum before official registration.
And you will be able to pay the meter only after completing the official sealing procedure. Information on how to do this correctly is described in detail in our other article.
Installing a filling is a free procedure. You shouldn’t install it yourself; you’ll still have to call a representative of the management company.
Within some time, usually from three to five days, a local government representative will be sent to respond to your application. For normal working contact with him, you must have a verification certificate and a meter passport with you.
The specialist’s responsibilities include checking the correct installation order of the water meter unit and all its components, and also checking the integrity of the unit elements.
The water utility representative does not have the right to control the qualifications of the person installing the meter.
After checking and sealing the unit (with his own seal), the inspector will draw up a commissioning report, where he will enter the initial meter readings and provide you with a service agreement.
After carefully reading the contract, making sure that you are satisfied with everything, put your signature.
After signing the contract, you begin to pay for water according to the meter. Among the documents, the owners should have one copy of the service agreement and the act of putting the meter into operation.
It is also necessary to leave a technical passport and a certificate of verification of the water meter.An employee of the management company will need a technical passport; it is better to make a photocopy in advance.
There are times when re-filling is required. For example, the service life of the devices has expired, one of the elements of the unit has broken, or a new element has been added to the system.
Therefore, it is better to store documents separately from other papers, so that in case of an unforeseen situation they are at hand.
Problems during operation and their solutions
During the operation of the water metering unit, some problems may arise. Let's consider their types and possible solutions.
Whatever the problem, it is not recommended to fix the problem yourself. Use the services of specialists - this will save your time and money.
Calling a plumber to your home is much safer and more expedient, since the problem can concern completely different parts of the water meter unit. For example, the fault may lie in pipe connections. The coarse filter often becomes clogged; it needs to be cleaned or replaced. Breakage of the shut-off valves cannot be ruled out. In addition, contacting a plumber will help solve all problems several times faster. In most cases, the service is not that expensive or even free. Proper troubleshooting of the water meter unit will prevent further damage to the equipment and avoid further problems in the future.
Symptoms and corrective measures:
- Water flows poorly through the water meter. The coarse filter may be clogged. It is necessary to call a representative of the management company to eliminate the defect; he is obliged to clean the filter and re-seal it free of charge.Under no circumstances do this yourself; breaking the seal is tantamount to voiding the warranty.
- Broken seal. Don't fix it yourself. Notify the management company as soon as possible. You will have to pay for re-sealing, but this is nothing compared to the fines if the inspector discovers that the seal has been broken. You will have to pay the full amount of the tariff since the last inspection (maybe several years), as well as a fine for missing an application.
- Water passes through the water meter, but the readings are not recorded. The counting or rotor mechanism may have broken down. If you are sure that your water meter is faulty, you have the right to a free unscheduled inspection. This is the case if the warranty period has not expired.
During the inspection period, water payments are calculated based on the average minimum for the region. The inspection can take up to several months; sometimes it is easier to buy a new one.
Installing individual water meters is becoming an integral procedure in every home; the process is not so much labor-intensive as it is troublesome, but it is completely worth it.
By following the order in the sequence of work on installing a water meter, you not only save about 30% every month, but also have an incentive to use water wisely.
You may also find information about timing of meter verification and features of this procedure.
Conclusions and useful video on the topic
The video will clearly present the process of assembling units for installing cold and hot water measuring instruments:
The clear conclusion is that installing meters is beneficial for every family, since water becomes more and more expensive every quarter, and the supply of clean fresh water becomes less and less.
Installing a meter yourself or calling a specialist is a personal matter. As can be seen from the step-by-step instructions given in our article, you can perform the installation yourself by carefully studying the general recommendations and purchasing a meter and components that will be useful during the installation process.
And although a representative of a water supply company during sealing has no right to be interested in the qualifications of the technician installing the meter, in practice users are faced with different situations.
If you have any problem during sealing or want to share your installation experience, please leave your comments under this article.
In our new apartment, the meters were already installed at the time the property was handed over, that is, they were installed by specialists after finishing work. But at the water inlet to the kitchen (we have two inlets, in the bathroom and in the kitchen), the meters are installed in such an unfortunate place that they urgently need to be moved, since after placing the furniture there will be no access to them. Do I understand correctly - even if I just move the meters a few tens of cm up the same pipe, they will still need to be resealed?
If you have not broken the seal (wire) on the meter, then rearrange it as many times as you like.
Hello. In any case, do not take risks and call specialists to unseal and record the readings before moving the meter.Because if you accidentally damage the seal or the meter itself, you will have to pay a large penalty.
Actually, now the question is not how to install the meter, but how to extend its service life. It’s no secret that after the service life of a water flow meter has expired, it is not necessary to change it, but simply carry out a verification, which is several times cheaper than replacement. In order not to shorten the operating period, you should also not skimp on coarse filters in front of the meters. But before purchasing a device, you should find out if there is a company with a licensed activity for checking meters in your city.
The American meter is sealed, but access to the filter is free - why can’t you clean it yourself?
It's a difficult question. Installation companies love to seal everything they can. This includes filters, the sealing of which is not necessary, since unauthorized intervention is prohibited in metering devices, and the filter is a fitting.
Thus, guided by the phony law, they periodically roam around apartments and try to squeeze money from clients for supposedly licensed filter cleaning. You can clean the filters yourself.
But here you are wrong. The filter is sealed so that the meter readings do not rewind through it. So, there is a need for sealing!
And one more thing: it turns out that the user must watch day and night: is the counter working correctly? I know from experience that each specific case has its own unique nuances depending on the quality of the pipes and the specific layout of them before and after the meter, the quality and pressure of the water, the orientation of the meter, the fullness of the filter, the speed of opening/closing taps, etc., and so on.
And why will they charge based on the average cost? And who then will reimburse the payments made according to the meter readings? That. Is there a legal loophole for constant blackmail of the apartment owner? Wouldn't it have been easier to first develop and legitimize standard connection schemes and implement them in new buildings or during major renovations of old ones?
In the meantime, I have already experienced a “fire in a brothel during a flood” twice, because... the installers had to use all degrees of freedom of the upper and lower extremities, neck, torso, constantly express themselves brightly and loudly and even try to escape... A positive result was achieved at a cost an order of magnitude higher than the notorious 3800 rubles. But replacing the meter/s will obviously require complete rewiring.
Roman, forgive me, it’s not entirely clear what you are going to “watch” and why. As for the refund, in theory they should recalculate taking into account the money paid for the old readings, since this was not unauthorized interference in the operation of the meter.
Tell me, according to what documents it is allowed to install a flexible supply line after the meter in an apartment building?
SP 30.13330.2015: “7.2.7 - provide straight sections of pipelines on each side of the meters, the length of which is established in accordance with the requirements of the device passports«.
Hello. Water meter capacity is 1.5 m3/hour. We were forced to install a mini pump with a capacity of 2 m3/hour. Will such a pump fail due to the pressure of the water meter?
Air temperature is at least 50 °C - WHERE IS THIS?
Where? Yes in SNiP 2.04.01-85 “Internal water supply and sewerage”: ... “Water meters should be installed at the entrances of the cold and hot water supply pipelines to each apartment of residential buildings and on pipeline branches to shops, canteens, restaurants and other premises with ambient temperature from +5°С to +50°С and relative humidity not more than 80%, built-in or attached to residential, industrial and public buildings..."
On hot days indoors, natural ventilation does not work due to the fact that the pressure outside the building and inside are virtually the same. Therefore, it is likely that the temperature will rise to this level and even higher. If the meter is installed in a room without air conditioning and mechanical ventilation, it simply must work stably even at +50ºС.
Hello. This SNiP has long been canceled and replaced by SP 30.13330.2012, where:
«7.2.2 Meters at cold (hot) water inputs into buildings and structures should be installed in a convenient and easily accessible room with artificial or natural lighting and an air temperature of at least 5 °C.It is recommended to install cold and hot water meters in the same room (preferably combined with the room for installing the heat meter in the building's heating system).«
If the meter is installed on cold water in the open air under the sun's rays, rain and winds (and in the summer the air temperature in the sun goes off scale), then can a natural factor affect the magnetic tape of the meter? Or such studies have not been carried out and are not being carried out???? Let me clarify that the meter is not located in a well, but simply on a vertical gander, above the ground.
Hello. For installation in open spaces, as well as in wells, wet-flow water meters are used. The technical passport must contain clauses of approval for operation in conditions of differential temperature, open mode. However, even in such cases, it must be protected from the effects of groundwater, sewage, drinking and rainwater, and operated at a temperature of at least 5 degrees (the highest level is quite high).
In addition, upon admission to operation, you should have been given specifications and not connected the meter if the conditions of its installation were violated, which could lead to rapid damage or incorrect operation of the meter.
Hello! Please tell me. They invited a private plumber to change the DHW meter. When installing a new meter, he was hammering and knocking something. As a result, a leak started in the pipe at the junction with the tap. The private owner took the money and told me to urgently call plumbers from the housing office. An hour later the plumbers showed up and the meter was REMOVED. at that moment it jerked, the tap remained in my hand. Fortunately, the second plumber was turning off the water in the basement at that very moment. Flooding of neighbors was avoided.The plumbers cut the pipe and INSTALLED the meter again. Was it legal for a private plumber to charge me? Considering that it was during the process of his work that the leak started? Were installation standards violated? Or should he have checked the condition of the pipes in the first place? Should I stop installing the meter if I create a leak?
The apartment had meters, but they were not put into operation by the former owner. I installed new ones, inviting a mechanic from the management company. And now I am forced to pay not for replacement, but for installation of new ones. Are they right?
Hello. In your question you left quite a lot of unknown input. Starting from how the old meters were operated without commissioning, ending with how you removed the old ones and installed new ones without approval and preliminary verification. Agree to replace the meters before you are fined.
Fast. Government of the Russian Federation No. 354 of May 6, 2011:
«35. The consumer does not have the right to arbitrarily break the seals on metering devices and at the places where they are connected (attached), dismantle metering devices and carry out unauthorized interference in the operation of these metering devices.
62. If a connection (hereinafter referred to as unauthorized connection) of the consumer’s intra-apartment equipment to the in-house engineering systems is detected in violation of the established procedure, the contractor is obliged to draw up an act on the identification of unauthorized connection in the manner established by these Rules.
Based on the act of identifying an unauthorized connection, the contractor sends a notice to the consumer about the need to eliminate the unauthorized connection and makes additional charges for utility services for the consumer in whose interests such a connection was made for utilities consumed without proper accounting.
In this case, additional charges should be made based on the volume of the utility resource, calculated as the product of the capacity of the unauthorized connected equipment (for water supply and sewerage - according to the pipe capacity) and its round-the-clock operation for the period starting from the date of the unauthorized connection specified in the act on identification of an unauthorized connection made by the contractor with the involvement of the relevant resource supply organization, and if it is impossible to establish the date of the unauthorized connection - from the date of the previous inspection by the contractor, but no more than 3 months preceding the month in which such a connection was identified, until the date of elimination by the contractor such unauthorized connection. If it is impossible to determine the power of unauthorized connected equipment, additional fees are charged based on the volume determined on the basis of the consumption standard for the corresponding utilities with an increasing factor applied to such volume
10. Moreover, in the absence of citizens permanently or temporarily residing in the residential premises, the volume of utilities in these cases is calculated taking into account the number of owners of such premises
«.Hello, please tell me about SNiP. According to the rules, is it possible to install water meters in front of the heated towel rail? Or another installation option: after the tap, filter, meter are removed from the riser, in the upward direction, and to the consumers through a bend in the downward direction?
Hello.
Let's look at SP 30.13330.2012: “5.2.6 Heated towel rails installed in bathrooms and shower rooms to maintain the specified air temperature in them in accordance with SP 60.13330 and SanPiN 2.1.2.2645 should be connected to the supply pipelines of the hot water supply system or to the consumer’s power supply system. When justified, heated towel rails may be connected to the circulation pipes of the hot water supply system, provided that a shut-off valve and a closing section are installed«.
The meter is installed after the shut-off valves.
Your installation diagram is unclear. Please explain in more detail or agree on possible options in the Criminal Code, in fact, you will still have to do this.
I installed the water meter myself according to all the diagrams. But the water utility refuses to register it, here is their answer:
“This is according to the order of the Ministry of Regional Development, Activities and Housing and Communal State of Ukraine No. 270 dated 10/12/208. Acceptance into the guise of a regional university is subject to submission of the latest documents;
- a copy of the document confirming the authority’s right to accommodation;
- a copy of the supporting documentation for the specific processing equipment that will be included in the storage unit’s warehouse;
-copy of the act of capture -transferred work from the installation of a node in the region.”
Please tell me what is a “copy of the act of acquisition and transfer of work from the installation of a node in the region” and where to get it?
The act of acceptance and transfer of work on the installation of a metering unit is a document confirming the installation of the IPU by an organization that has a license to install such devices, which you should have taken and signed with the relevant company.
We are located in the Russian Federation, so I’ll just give you an excerpt from your state’s website:
«Having purchased a water meter that is certified for use in Ukraine and has a Gosstandart stamp on the seal, you contact the Kakhovvodokanal branch of the KVU, where they will make a photocopy of the meter’s passport with its unique number and add it to the subscriber database. There you will be given an invoice to pay for the connection work and the water meter will be installed within 10 calendar days. Installing a meter in an apartment for plastic pipes will cost 352.7 UAH, for metal pipes - 440.5 UAH. The high price, in the second case, is associated with the need to use a welding machine with acetylene gas«.
Hello, please tell me whether it is possible to install a multi-jet meter in an apartment?
Hello. Yes, you can install a multi-jet water meter in your apartment, this is not prohibited. You just need to take into account that the multi-jet meter can be installed on pipes with a diameter of 15-50 mm. And it is best to take a “dry” type meter so that the particles contained in the water do not cause errors in the process of measuring consumed water.
Good day! The situation is as follows: for a long time there was no meter in the apartment and payments were calculated according to the standards.I independently installed the meter, wrote a statement in accordance with the requirements of the Government of the Russian Federation 354, in the column for information about the organization that installed the meter, I wrote that it was not saved.
Vodokanal refused to put the meter into operation, citing the fact that I did not have any specifications, which I first had to request from them in writing. No one came to my apartment and looked at how the devices were installed. Is this legal?, since in the order established by the government in Resolution 354, paragraph 81, the obligation is not specified, then documents are requested before installing the meter.
As far as I know, before installing the meter yourself, you need to take it for verification, after which you will be issued the appropriate paper stating that the equipment can be used as a water consumption meter.
It is possible that the meter you installed really does not correspond to those. conditions. You need to invite a certified specialist who will install the meter, register it, and you will pay for the consumption. Otherwise, you will have to pay for water without a meter.
Good afternoon New private house, I installed a 20mm meter, the water utility refuses registration, citing my project, which says 15mm. But I understand that for a private home this is not enough. Is it legal for them to force me to do this? What should I refer to in my application to the Director of Engineering Networks?
Hello. According to SP 30.13330.2012:
«7.2.11 A meter with a nominal diameter previously accepted in accordance with 7.2.10 must be checked:
a) to skip the calculated maximum second flow rate; in this case, the pressure loss in cold water meters should not exceed 0.05 MPa for vane meters, and 0.025 MPa for turbine meters.
b) to skip the sum of the calculated maximum second flow of cold water and the calculated fire-fighting water flow; in this case, the pressure loss in the meter should not exceed 0.1 MPa for vane meters, and 0.05 MPa for turbine meters.
c) the ability to measure the calculated minimum hourly flow rates of cold and hot water; in this case, the minimum water consumption for the selected meter (according to the device’s passport, depending on the metrological class) should not exceed the calculated minimum hourly water consumption.
7.2.12 If the selected meter does not meet conditions a) or b), then the meter with the nearest larger diameter should be accepted for installation. If the selected water meter does not meet condition c), then the meter with the nearest smaller diameter should be accepted for installation.
If the meter does not simultaneously meet conditions a) and c) or b) and c), then the following should be installed:
-combined meter (combined turbine and vane meter with a built-in water flow switching valve);
-meter of metrological class C (according to the current standard for water meters);
- several meters of the same diameter (installed in parallel), the number of which is determined by calculation, subject to the requirements of 7.2.11.
»You just need to make changes to the project based on hydraulic calculations and approve them. And then write an application for filling.
It would be nice to know what else is written in your technical specifications, since we don’t know, we have to answer without taking this document into account.
Good afternoon. In 2011, meters for cold and hot water were installed, then the expiration date expired and we did not immediately change them; for several years, we paid according to the standards. In December 2019, they called a plumber from the housing office and he installed and sealed new meters; I did not provide the old readings and device numbers. The housing office refuses to register new meters until I hand over the readings of the old ones. Why and is this legal? After all, the old ones have already expired almost twice.
Hello. How did it happen that you paid according to the standard for so long? Representatives of the management company issued you a payment according to the standard due to what circumstances? Failure to provide information or refusal to replace/verify the IPU?
Look... PP No. 354:
«81(4). During the commissioning of the metering device, the following must be checked:
a) correspondence of the serial number on the metering device to the number indicated in its passport;
b) compliance of the metering device with the technical documentation of the device manufacturer, including the configuration and installation diagram of the metering device;
c) presence of signs of the latest verification (with the exception of new metering devices);
d) operability of the metering device.
81(5). Non-compliance of the metering device with the provisions provided for in paragraph 81(4) of these Rules, identified by the contractor during the inspection, is grounds for refusal to put the metering device into operation.
81(6). Based on the results of checking the metering device, the contractor draws up an act of putting the metering device into operation, which indicates:
«.a) date, time and address of putting the metering device into operation;
b) last names, first names, patronymics, positions and contact details of persons who took part in the procedure for putting the metering device into operation;
c) the type and serial number of the installed metering device, as well as the location of its installation;
d) a decision to commission or refuse to commission a metering device, indicating the grounds for such refusal;
e) in the case of putting the metering device into operation, the readings of the metering device at the time of completion of the procedure for putting the metering device into operation and an indication of the places on the metering device where control disposable number seals (control seals) are installed;
e) date of next verification
As you can see, the Criminal Code has no grounds for refusing commissioning, except for point d). However, this point is necessary for recalculating old readings with new ones. Since you paid according to the standard, you just need to draw up an act of failure to provide readings from the old meter and pay for the last billing period according to the standard, despite the starting readings of the new meter. And register the old device as “out of order,” which in fact it is.
Propose this option to the management company. Also, if they are stubborn, require by law a written justification for the refusal. Moreover, you have a month before the actual registration of a new meter. With this written refusal, go to Energosbyt and consult with them what to do in your situation. Be sure to bring all recent receipts.
The new meter will be put into operation for you.
I installed the meters, wrote a statement asking them to come and seal them, and they told me to wait a month. Will they be sealed if they are in boxes? Renovations are underway and I want to sew up all the pipes. Only the entrance from the riser will be visible.
Hello.I have a problem, I recently discovered that water was leaking on both sides of the water meter, I wrote a statement, a mechanic came, he couldn’t turn off the incoming tap, he told me to write an application to replace the tap, they wrote,,, they said you don’t need to pay anything for a replacement, just buy a tap , we bought it, another mechanic came and said that we needed to pay 700 UAH. and to him. They asked for a check for payment, but he ran away))) what to do and what to do?
Is such installation allowed: a ball valve on the inlet pipe from the riser - a piece of pipe up to 1 meter long for installing the assembly in a convenient place, and then the standard assembly: oblique filter-meter-check valve and then wiring to the mixer, toilet, etc. ?
Hello. Is it possible to install a flexible connection after the water meter in an apartment?
Hello. The rules for installing water meters do not prohibit the installation of flexible hoses.
Hello, I read your competent answers and want to ask my question. The following situation arose: the management company accepted my water metering in this composition: faucet-fine filter-water meter, sealed it, lived quietly for 1 year. An inspection specialist came after a change in the management company and drew up a report of illegal tapping, referring to my filter with the tap. I received a notice to remove the tie-in, install a coarse filter, within a week I removed it, installed it, sealed it, drew up a report, but recalculated it for 3 months for 10,000 rubles. in the payment slip. The question is whether it is worth fighting for your money or is it useless. After all, in my opiniona fine of 1,500 rubles by a court decision for an individual, but in my case there is a recalculation of the volume of water consumption, which was not and has not been proven. Thank you.
Good afternoon
How to install a cold water meter correctly, vertically or horizontally?
Hello. They installed the meter, came from the dealership to seal it, and they said it doesn’t match. Remake. There should not be such connections, what if you remove the meter and install a pipe and use water without a meter... is this remark justified and what can be done? Will adapters with lugs be enough for the seal?
Hello! At what height should tie-ins be made into common house risers for hot water supply and hot water supply? Meters must be installed in close proximity to the tapping points or can be moved to other places (premises). Thank you!
My hot water meter had not worked for two years; it had expired and I didn’t change or connect it. For two years I paid at the general rate for hot water. Then I decided to install a new meter. I installed it myself and called an employee to seal the meter. It turns out that I reinstalled the meter. And for some reason they drew up a report and a fine against me for unauthorized replacement. After all, it didn’t work for me for two years - they turned it off themselves after 4 years, I paid at the general tariff.
Hello!
Please tell me! The management company does not seal the meter, citing an incorrect assembly diagram, but without attaching any confirmation to this.The meaning is this; the cold water riser is located a meter from the meter, a tap is left on the riser at the request of the local plumber, and then a meter away the meter is located along with the tap and filter, and this distance is sewn into the wall with a 20 polypropylene pipe. There are no detachable connections between the taps - there is no possibility of dismantling either, everything is walled up! What to do, does the management company have the right not to seal the meter, referring to the second tap in the system, but without attaching a link to the law that indicates this?
Hello! The oblique coarse filter (dirt filter) is clogged. which stands in front of the water meter. Neither I myself nor the specialists from the management company were able to disassemble the filter to wash the filter element. All that remains is to replace the filter with a new one. And this happens almost every year. The water in the system is dirty. To eliminate such problems with the filter forever. I decided to install a compact filter for mechanical water purification in front of the water meter with the ability to remove accumulated contaminants without removing the mesh inserts (washing filter). However, the local water utility refuses to seal the meter with such a filter. Allegedly, I will use it to steal water to the meter! Are the actions of the water utility legal in this case?
SP 30.13330.2016 CODE OF RULES INTERNAL WATER PIPING AND SEWERAGE OF BUILDINGS Article 7.2 states. that a mechanical water purification filter should be installed in front of the water meter. This filter (which I want to install) is designated on the manufacturer’s website as a mechanical water purification filter with the possibility of washing.
Hello. Tell me what to do in this situation. I installed a cold water meter with a nominal diameter of 20mm, since the pipe is 20mm in diameter.Vodokanal workers do not want to install a seal, since according to their standards, they install it only in private houses, and not apartments. Is there such a norm? Thanks for the answer.
Good afternoon. The meters don’t fit in my riser, additional work is needed; elbow-American-meter-elbow-pipe-elbow. They offer prices from 6500, but they don’t want to specify additional work as much as they want. It's cheaper in the store. I sent a letter to several companies to send price estimates, but they did not want to respond. Best regards, Vladimir
If there is no water project, can a meter be installed?
Good evening. A meter for drinking water consumption does not require any design.
in 2008, through a specialized water supply system organization that installs water meters, the sealing is carried out by POVV. After 4 years in 2012, when replacing the DHW meter, the POVV master told me that the meters are located far from the inlet taps (DHW -35 cm, cold water - 40 cm-) and does additional sealing of the inlet taps. This year, when changing the meter, despite the presence of seals on the water inlet taps, another specialist refuses to seal it, citing that the meters are far away, and the seals are not broken. Please advise what to do, because there is a concept of an additional connection that is sealed.
