Replacing the hot or cold water meter - features and procedure. Replacing a water meter and checking it: what you need to know about it How to change a water meter in an apartment

Water meter owners are often surprised at this a large number ads from companies and private firms that specialize in water replacement. At the same time, it is completely unclear where this excitement comes from and what is its cause. Is it really necessary to replace the water meters, as the dispatchers of these companies assure? Let's look at the procedure for replacing water meters in an apartment and deal with this problem.

Actual reasons for replacement

Few of the apartment owners know that a replacement is necessary only when the device presumably or accurately shows incorrect data. If you suspect that the meter is blatantly lying, it is necessary to invite DEZ specialists who check the water meter in the apartment, without the need to dismantle it.

It should also be borne in mind that the recommended waters are not the timing of their replacement. But this is exactly what the owners are trying to convince the people who call on the ads. The date on which it is necessary to change the water meter is regulated directly by the manufacturer, as the period when it is desirable, but not necessary, to perform a scheduled check of the mechanism. So, for a cold water meter, the period is 6 years. And for the meter, hot replacement is recommended every four years.

The law, which required such checks to be carried out, was changed in 2004. The changes affected the deadlines - now they are gone, the checks are illegal. The meters can work for 12-18 years without any problems. The term indicated in the technical passport for the meter is by no means a guide to replacing the equipment. These data are often entered into the technical data sheet manually, which means that they do not need to be considered a regulation. The real reason for replacing the meters is inaccurate readings. Inspectors from the organization, as well as the owner himself, can report this.

Reasons for the failure of water meters

The water meter can fail for only two reasons. This is illegal interference with equipment and poor quality water. Any action - for example, Neodymium magnet and any other device, the purpose of which is to slow down the apparatus. These experiments have a negative impact on the performance of the water meter. It should be remembered that during the check, specialists will definitely identify any interventions and causes of equipment failure. For this, fines are threatened.

Now about the quality of water. When it flows through pipes in a water supply system, particles of debris and other impurities remain on the coarse filter. Over time, this mesh can become clogged, and debris along with the liquid will fall into the counter mechanisms. Wet debris works in the same way as abrasive - it is detrimental to the delicate parts of the meter.

Is it possible to independently replace the meter

Let's see how to replace water meters yourself. For example, the device is out of order. Is it possible to change it with your own hands or do you need to use the services of plumbers from their housing department, management company and other organizations? What is the owner of an apartment to do?

The procedure for replacing water meters in an apartment requires approval in any case. For replacement, it may be necessary to turn off the water supply throughout the riser - residents cannot make such decisions on their own. This is done by the management company of the house. Before changing the water meter, it is better to find out the position on this issue from the management of the housing company. If the housing department claims that it is necessary to call the appropriate specialist for replacement, then it is better not to start a dispute. This is the procedure for replacing meters in an apartment in a particular house. There is nothing to be done about it. At the same time, by law, residents and apartment owners are not prohibited from installing meters or changing them on their own.

If the meter has already been installed, then it will not be difficult to install a new one in its place. Even a person who holds a key in his hands for the first time can do this. However, after installation, the procedure for replacing independent water meters in an apartment requires that the housing department employees check the correct installation of the device, put a mark in the technical passport and seal the device.

Replacing an unregistered meter

There are times when the water meters have not yet been registered. Here, the procedure for replacing water meters in an apartment is extremely simple - you just need to remove one device and install a new one in its place. Then the housing department workers are called for sealing.

After sealing, the owner receives in his hands documents, passports with seals, permitting. Then all the papers are transferred to the DEZ, and then to the EIRC.

Replacement of a registered water meter

It doesn't matter for what reason the owner decided to replace the water meter. The procedure for replacing water meters in an apartment does not change. You need to get access to the riser. Further, the device itself changes, after which an act of putting a new water meter into operation is drawn up. In this case, they must enter data from the previous counter, as well as information about the new device. When the replacement steps are completed, you need to contact DEZ to register new metering devices.

The removed meters cannot be used in any way. Further, the technical passports of the units are submitted to DEZ, where all the necessary stamps from the metrological services are already placed. You also need to have permission to use. Further, the same package of documents is submitted to the EIRTs. After that, the new devices will be registered.

How do I replace a device?

Let's see what is the procedure for replacing water meters in an apartment and how to replace it. The nuts are easily unscrewed with an adjustable wrench. But before that you need to shut off the water on the riser. Nuts tend to give in easily. But if this is not the case, then it is easier to cut them off. It is useless to warm it up. The meter is removed, and then it is important to check the cleanliness of the pipes on both sides. It is also recommended to install a new coarse filter. It is important to remember to clean the fitting and get rid of the old gaskets. New silicone or rubber ones are installed. Paronitic ones should not be used - literally 2 years will pass and the nut will firmly boil. Next, a new apparatus is installed in its place, replacing the gaskets in the nuts. The latter should be twisted on each side by half a turn. At the same time, it is not necessary to tighten too much. When water gets into the system, if there are leaks, you can tighten the nuts a little.

The installed devices must be sealed. To do this, they write applications for sealing and wait for the appropriate specialist. After sealing, the appropriate act and permission to operate the mechanism will be issued on the hands. The specialist needs to provide a technical passport for a water meter, as well as a quality control certificate. Replacing the meter hot water do it yourself in the same way. There is nothing complicated in the process of replacing a hot meter.

When the water meter changes the master

If for some reason it is impossible to replace the device on your own, then you should invite specialists from the management company to solve this problem. It is important to this specialist had the appropriate license. But the services of the master will take more time than replacing the water meters yourself. How to replace in this case? The first step is to write a statement. Next, the day and time of the arrival of the specialist are discussed with the management company. Then the master will provide an act on the work carried out, which will indicate the data on the integrity of the seal, as well as the integrity of the meter body.

The technician will then physically replace and seal the meter. After that, the water meter can be fully exploited. If the metering device was replaced by masters from a private company, then you need to additionally call specialists from the management company. They will record the very fact of replacement, as well as the process of sealing and the integrity of the seal. Without this, any replacement actions will be considered illegal.

Finally

After you have all the documents in your hands, which says that the device can be used, it remains only to take these papers to the settlement center. Here's how to replace the water meter yourself - the main thing is to keep order.

This is done by tenants for several reasons:

reduce the cost of using water;
prepare in advance for the day when devices for calculating the consumed water will be an obligatory attribute of every apartment.

Figure 1. Cold water meter.

What are the counters for?

Devices for calculating hot and cold water save tenants up to 1000 rubles. monthly. At more the savings living in the apartment will be much greater. But the law says that all these devices must be checked after a certain amount of time. How are water meters replaced? It all starts with the installation: devices need to be bought, installed and sealed. You can do all these work with your own hands, but if they are incorrectly connected to the pipes of the system, problems may arise with the sealing of the products. It is better to order the execution of work in a special organization.

If all equipment is installed and sealed, it must be remembered that after 4 years the hot water meter must be checked. The life of a cold meter is 6 years. If you miss these deadlines, you will be recalculated and charged for water at the tariff. It is much more expensive than paying for meter readings.

To check the meters, you must remove them and take them to the repair service. This procedure is expensive, its duration is quite long. But replacing the meter with a new one will be even more expensive. You can only change water meters for cheaper ones for better devices. All replacement takes place in 2-3 hours.

Figure 2. Hot water meter.

What is the purpose of replacing counters

It is necessary to change water meters for those tenants who have expired metering devices or have not passed the test. Can you do it yourself? V privatized apartment replacing the water meter is the privilege of the homeowner. In some regions, local governments may be able to cover these costs, but are not required to do so. the federal law Article 13 provides that metering devices must be installed by the owner of the house. But is it necessary to seek help from plumbers? Or can you change metering devices yourself?

Coordination of installation or replacement of meters must be taken. Indeed, in any case, it is required to turn off the water in the riser. If the housing department insists on their specialists, they will have to obey. If you already had such equipment, the law does not prohibit making the replacement of meters with your own hands. It is not difficult to attach a new device to the prepared place. Anyone can handle this task. It is enough to be able to work with an adjustable wrench and a sealant. But after installation, you need to call a representative of the housing department to the house. He will inspect the devices, seal them and make a corresponding entry in the data sheet. After that, you can pay again according to the readings of the devices.

How to replace a water meter in an apartment? To do this, you need to prepare some tools and equipment:

calibrator;
adjustable wrench(fig. 3);
FUM tape or sanitary flax;
gaskets for counters;
the counters themselves;
soldering irons for polyethylene pipes;
adapter couplings.

Figure 3. Adjustable wrench for replacing the meter.

If there is a water shut-off valve in the apartment, you need to close it and unscrew the nuts of the metering devices. They always twist clockwise and unscrew in the other direction. The fittings are cleaned of used gaskets and are equipped with new products. Better to use silicone or new rubber pads. It is also necessary to clean the coarse filters. All fittings must be brass.

Free legal advice:

The rules for replacing meters require inspection of pipes for leaks and damage. If there are any malfunctions, they should be eliminated. There are arrows on the meter bodies that help in the installation of the instruments. They should be directed towards the water flow. The nuts are hand-tightened to the end and turned with a wrench by 1-1.5 turns. When water is turned on, there should be no water droplets at the joints.

Conclusion

The law requires the installation of gas, water and heat meters in the apartment.

Water meters are devices that help to save about 1000 rubles per month. If the family is large, then this figure will be much higher. If the meters are already installed, then after 4-6 years they need to be checked. Defective devices should be replaced with new ones. You can do this yourself. But for the final commissioning of them, you need to call a representative of the housing department for inspection and sealing. There are many types of counters. It is recommended to install products made in Germany. They serve much longer than domestic ones, up to 20 years.

It is better to entrust this work to specialists. Then the housing department will not have any questions. These workers are well aware of the order of execution. installation works and do everything in a maximum of 3 hours. Even if the device malfunctions, the company that installed it will be responsible in this case.

Is it possible to independently replace cold and hot water meters

Mounted on water pipes in the apartment, hot and cold water supply meters have their own regulated service life. Even if there are no mechanical faults and breakdowns, the hot water meter is designed for four years of operation, and the cold one for five years. After the end of this period, it is imperative to check or replace the meters.

The verification of devices is done by representatives of workers of housing and communal services. According to the rules, the specialists themselves must remind the owner of the end of the service life of the meters, agree on the visit of the ZhEK employees, conduct a check with the completion of a standard verification certificate. The original document should be kept until the next scheduled inspection of the device. Also, the verification certificate will be required in case of any disagreement on payment for cold and hot water supply, in order to conclude an agreement with the company supplying water.

The verification process takes about ten minutes and does not require special actions, the representative of the housing and communal services will verify the meter number, check its readings and enter it into the document. If the meter is found to be faulty, the owner of the apartment is obliged to purchase a new one at his own expense.

It is possible to independently replace the consumed water meter, and the process itself is relatively simple. At the same time, it is still necessary to register the counters with the company and seal them.

It is worth remembering that local management organizations in different cities may have their own requirements for the installation and registration of individual water supply meters.
You should definitely check with the representatives of the housing and communal services or vodokanal about their rules and regulations in order to avoid a conflict situation and a fine.
If you have doubts about the legality of your actions, it is better to play it safe and entrust the replacement of devices to licensed specialists.

Today, there are two opposing opinions about the possibility of replacing the meter on our own. The main argument against installing devices with your own hands is the law - Government Decree of February 10, 2004, where in paragraph 4.7. there is a phrase that "installation, repair and maintenance of water meters are not allowed by consumers." It turns out that if you yourself replaced the meter, you can incur administrative liability in the form of a fine, and the service has the right to refuse to register and seal the device. In practice, this means that only companies licensed to carry out such activities are allowed to change meters. There are many such organizations in every city, and new counter you will be installed the next day after the application. If you installed the device yourself, then the housing office may require you to dismantle it and contact a specialist. But, as mentioned above, such strict requirements do not apply everywhere, so check the details with your housing and communal services or management company.

Free legal advice:

What else is fraught with replacing the water meter with your own hands? In case of incorrect installation with violation technological requirements, pipes may be damaged or the tightness of the joints may be broken, which will lead to flooding of personal property, as well as the apartments of neighbors. And then it will not be the ZhEK who will be responsible, but the initiator self installation water metering devices.

If you nevertheless decide to replace the hot and cold water supply meters yourself, we recommend watching a detailed video instruction on how to do it correctly.

Required tools and materials for installation:

new water meter with registration certificate;
adjustable wrench;
gaskets;

First of all, shut off the water in the inlet pipes. Today, every apartment has valves that shut off the flow of water into the apartment. If there are none, you must contact the housing office and agree on the day and time for turning off the water throughout the riser. Then use an adjustable wrench to unscrew the nuts on both sides of each meter. After dismantling the device, clean the fittings from rust, corrosion and dirt, rinse the filter mesh well from debris and large mineral particles. If you cannot clean the filter, we recommend purchasing a new one, because it is he who protects the counter mechanism from impurities in tap water... Install new gaskets. When choosing gaskets, we recommend staying with silicone ones, then the risk of leakage will be minimized.

In addition, then additional rewinding is not required. Fasten the new meters with nuts, while not confusing the meter for hot and cold water - their principle of operation is slightly different. Carefully look at the water direction markings on the meter body and connect the right sides for water outlet and inlet. Everything! Do not forget to call the representatives of ZHEU for sealing and registration.

Causes of breakdowns and procedure for replacing water meters

Many owners of water meters are quite rightly surprised by the huge number of ads from companies specializing in the replacement of metering devices. Moreover, it is not at all clear where this excitement comes from and what was the reason. Is it really necessary to change the meters for cold and hot water, as the dispatchers of these most notorious organizations assure of this?

The procedure, rules and guidance on where and in what case to go to replace accounting equipment in the apartment, we understand below. The procedure is actually not as complicated as it is drawn.

Topical reasons for replacing water meters

Important: few consumers know that it is necessary to change a water meter in an apartment only when it presumably shows incorrect data. Moreover, if suspicion arises, you need to invite a specialist of the DEZ, who will check the meter directly in the apartment without dismantling it.

At the same time, it is worth knowing that the recommended period for calibrating water meters is not a period for replacing the device. But this is exactly what the so-called specialists in the replacement of water metering equipment assure after calling them. These terms are regulated by the manufacturer (for a device for cold water - every six years, and for a meter for hot water - every four years), as terms for the desired check of the mechanism. In addition, the law of the Russian Federation, prescribing the timing of checks and the use of monitoring equipment, was changed on February 10, 2004, No. 821. Now mandatory equipment checks have been canceled, and even without them, your meter can be "lucky" and work to its fullest without a single glitch. Everything here is purely individual.

Free legal advice:

Important: the terms indicated in the data sheet of the water meter are not a guide to replacing the meter. Moreover, these terms are entered into the passport manually, which is not a regulation.

The real reason for replacing the water meter is the unreliability of its readings. Moreover, this can be suspected by both representatives of the checking organization on the basis of the data received, and the owner of the meter himself. In the second case, you must immediately contact the supplier for a master's visit to your house in order to check the device.

Causes of breakdowns of the mechanism

Failure of accounting equipment occurs for two main reasons:

Unlawful interference with the operation of the device. This is the use of a neodymium magnet and other things to slow down the device. Such experiments strongly and negatively affect the operation of the water meter. In this case, it is always worth remembering that when checking the meter, the master will definitely identify the cause of the breakdown. This means that the fine will not be long in coming.
Poor water quality. Everything is simpler here. Water, flowing through the water supply pipe, gives up its particles of debris to the coarse filter. But, unfortunately, over time, the filter mesh becomes clogged, and debris gets into the water meter mechanism. Over time, the device wears out from such "guests" and breaks down.

Procedure for replacing the device

In order to replace a worn-out water meter, it is necessary to perform a certain procedure and use (receive) certain documents for this.

So, if the wrong course of work of the water meter is revealed and there is a desire to replace it with your own hands, then it is necessary to write to the controlling organization an application for the visit of the master to dismantle the meter. A specialist who comes must give you a document (act) in which it will be written that the seals at the time of removal of the old device were intact, like the body of the device itself. This document is called an act to carry out work on the change of accounting equipment.
After receiving such paper, you can proceed directly to work. To do this, close the shut-off valve.
After that, you can dismantle the old water meter using an adjustable wrench. As a rule, the union nuts are unscrewed rather quickly. But if, nevertheless, the nuts do not give in, you will have to cut them off. We remove the meter and check the cleanliness of the supply pipes on both sides. It will not be superfluous to clean the coarse filter. Or even replace it with a new one.
Now you can mount the new device to cold or hot water in its place by replacing the gaskets in the union nuts.

Important: the union nuts should be tightened evenly on both sides by 0.5 turns. When doing this, do not tighten too much. When water enters the system, it will be possible to stretch the fasteners a little in case of leaks.

Free legal advice:

The installed new meter for cold or hot water must be sealed. To do this, we again write an application for sealing and wait for the master. The specialist seals the water meter and then issues an act of putting the device into operation. But during the visit, the specialists will have to provide him with the following package of documents:

Technical passport of the meter;
Certificate of inspection and the proper quality of the mechanism.

If the counter changes master

If the independent replacement of the accounting device is not within your control, then for this you can invite a master from the management company or a specialist from a private organization. At the same time, it is important that such a professional has a license to perform work. Where to go specifically, you can consult with your neighbors. They, for sure, will prompt a proven specialist option.

The procedure will be as follows in this case:

We write a statement to management company to replace the meter. We discuss the day of the master's visit in advance.
The specialist is obliged to provide you with an act on the performance of work on changing the accounting equipment, which will also indicate the fact of the integrity of the seal and the body of the water meter.
After that, the specialist replaces the old mechanism with a new one and seals it. An act on the introduction of the water meter into operation is also issued.

Important: if a master from a private organization will replace the water meter, then you will have to additionally call the master from the checking company to fix the fact of dismantling the device and sealing the new water meter. Otherwise, all actions to change the device will be illegal.

After the new water meter is installed, and the documents for putting it into operation are on hand, all that remains is to take the papers to a single settlement center or to a water supply company for your home.

How to replace the water meter yourself?

Cold and hot water meters that are installed in an apartment have their own operational life. If absent mechanical damage, then the cold water meter is designed for 5 years of operation, and the hot one - for 4 years. After the end of this period, the water meter requires verification or replacement with a new device. Management companies strictly monitor compliance with these rules and require replacing the water meter according to the expiration date without fail.

Self replacement water supply meters is not a complicated procedure, however, it is advisable to clarify in advance the possibility of its carrying out in the relevant services. Quite often, these companies insist on replacing water metering devices by their specialists, since this service is paid and due to the proceeds from its provision to consumers, you can significantly replenish the organization's budget. At the same time, from the standpoint of a water consumer who has the ability to independently replace the meters, these are unnecessary expenses that can be completely avoided.

Even in the absence of special skills, replacing water meters should not cause any particular difficulties. You will not need special plumbing tools for this either. To replace the water meter yourself, you only need an adjustable wrench.

DIY step-by-step instructions for replacing the meter

First you need to turn off the water (a tap is installed in front of each water meter). You do not need to call the ZhEK employee - do it yourself.
The absence of water in the system must be checked on any mixer. If the water from the tap continues to flow, then in addition to the water meter, the shut-off tap must also be replaced.
Even if the tap is turned off, there is residual water in the pipes. In order to remove them after removing the counter, you should prepare rags in advance.
The old water meter can now be removed using the tap.
On the squeegee, unscrew the nuts (unscrew the hinged nut counterclockwise).
After removing the counter, you should remove the old gaskets, and then cleanly clean the ends of the squeegee from possible remnants of rubber stuck from the gaskets. Cleaning can be done with a regular knife or screwdriver.
The new meter is installed in place of the old one, and for high-quality sealing of the connections we use paranitic or rubber gaskets. The thread of the water meter does not require additional sealing, as this will only complicate the tightening of the nut.
Please note that the device must be installed in the direction of the water flow (an arrow is drawn in the required direction on the body of the water meter for orientation).
After that, we install gaskets between the squeegee and the counter, tighten. For convenience, we hold the water meter with one hand so that it does not scroll. It is not worth tightening too much, it is better to tighten it additionally later than to spoil the gasket.
Now you can open the shut-off valve and make sure that the connections are reliable and tight (the valve on the mixer opens all the way).

Features of replacing the hot water meter

Performing the same manipulations that were listed above, you can replace the hot water meter, while taking into account some of the features. This meter differs in body color from the cold water meter (it is important not to confuse these devices during the installation process). It should be noted that sometimes slightly warm or even cold water is supplied through hot water pipes. In this case, the water meter will consider it as hot, at the appropriate rate. Therefore, in the process of selecting, replacing and installing a new measuring device for hot water, you should follow the recommendations of a qualified specialist. A filter is included with the new device, special fittings with union nuts and gaskets to ensure tightness of the joints.

Free legal advice:

It should be borne in mind that there is dirt in the water pipes (even in new ones). To release it, and with it the air that remains in the meter, you need to open the tap at full power for a few seconds. It is very important. As the air remaining in the device can affect the correctness of the readings of the water meter.

In conclusion, I would like to note that it is much more advisable not to buy cheap water meters of dubious quality, but to opt for more expensive and quality products... This will protect you from the need to change your water meters frequently due to constant breakdowns.

Very interesting article... Now you do not need to call the master, I can replace it myself! Thank you)

It was necessary to urgently change the meter, but could not figure out how to do it correctly. I saw this article in time. Thanks a lot. They explained everything clearly.

Replacing water meters yourself

It is necessary to replace the water meter when it is damaged or the expiration date has expired. If the second, then it is necessary either to check or change to another measuring device.

Free legal advice:

If you completely exclude the possibility of damage, then it should be remembered that the cold water meter is set for 5 years, and the hot water meter - for 4. Usually, specialists from the housing office are called for replacement, but you can do this yourself. It is quite simple to do everything yourself, but everything must be coordinated with the head of the service, and after installation, it is imperative to install a seal. So, in our article we will consider the main points of replacing water meters.

When does the meter need to be replaced?

Each cold and hot water appliance has its own expiration date, which is given by the manufacturer. After this time, the meter may give inaccurate account data and have technical problems. Life cycle you can look in the passport of your equipment, but usually it is:

For hot water - 4 years;
For cold no more than 6 years.

SanPiN 2.1.4. Provides for a temperature in the pipes of no more than 60 degrees of hot water, since at a higher degree, the water becomes chemically aggressive and therefore damages the device.

Important! As soon as the term is over, you need to make a check, which is done by special services. However, this takes about 2 weeks and is quite expensive. Therefore, it is sometimes more profitable to purchase a new meter.

Why is there a need for replacements?

There are such reasons to change the device:

Free legal advice:

Breakdown of the mechanism;
Expiration date;
Change of requests of Vodokanal;
Check that showed a malfunction. It's just that many meter owners believe that it is easier to replace them than to repair them.

Design features of meters

Cold and hot water meters are very different in design, so this should not be overlooked. They have some signs, for example, blue or red. Install counter warm water on the cold pipe it is not prohibited, since they do not differ in functionality, but they also do not bring profit, since they are more expensive. On the contrary, it is prohibited. You simply won't be allowed to install a hot water meter on cold pipes. The end result will be that you have to purchase another mechanism.

Today there are several installation options:

Tachometer device. One of the most popular apartments and houses in the choice of tenants, as it is budgetary and durable. Counters of this type are of the following subspecies: single-jet and multi-jet; dry and wet; combined; with a pulse output.
Vortex;
Electromagnetic;
Ultrasonic.

Replacement process principle

The replacement process is usually carried out by specialists in this field who have permission to perform this work. The installer is usually responsible for performance. Therefore, if a breakdown occurs, the company's employees must repair this device.

It is worth noting that it is legally possible to carry out the installation independently, but only with subsequent verification of the correctness of the actions taken and sealing.

Can I change the counters myself?

If you want to replace the water device yourself, it is very important to do this in accordance with the relevant structures. After all, you will need to turn off the water supply through the riser, and this can only be organized by the structure that serves the given house. Based on this, the first thing we do is apply for a permit from the housing department. If the guide still recommends specialists, then you'd better agree so that you don't have any problems in the future.

Free legal advice:

Important! The first installation must be done by professionals in this business.

The legislation, of course, does not prohibit the installation on its own if the place for installation is already ready. After all, it is quite easy to install the device itself. However, after installation, it is imperative to show the meter to representatives of the housing department, who will check the correct operation of the mechanism.

Obtaining a Replacement Authorization

The first thing to do is to purchase a meter for cold or hot water that matches the flow temperature. It is very important to comply with all the requirements of SP 30.13330.2012, GOST P 50601-93. And also register it in the State Register.

Based on this, it is better to purchase a water meter in a specialized store, where a certificate of conformity is included with it.

Important! Look in the data sheet for the date of inspection and the warranty period.

Free legal advice:

What tools do you need to perform a water meter replacement?

You will definitely need the following tools to perform these works:

Water meter;
Special gaskets for the device;
Adjustable wrench;
Calibrator;
Soldering iron;
FUM tape;
Adapter couplings.

Documents required for self-replacement

In order to draw up an act with special organizations, it is necessary to have the following documents:

Technical passport of the water meter;
A certificate certifying that the device has passed the test.

Attention! If you have all these documents, then no questions will arise.

What is the correct sequence of replacement steps

When replacing the water meter, you yourself need to invite a campaign employee to remove the seal and draw up an act for the implementation of these works.

The process itself is performed in the following sequence:

Free legal advice:

We turn off the common tap for supplying the water flow;
We check if we managed to block the pressure;
We unscrew the union nuts with a special adjustable wrench;
We remove the old water meter;
We remove the old gaskets from the inner surface of the nuts;
We install new nuts and gaskets;
We put a new water meter and make sure that the arrows on the sensor coincide with the direction of the water;
We tighten the nuts in the direction of the thread.

Attention! The installation process for a cold and hot water meter is identical, but the main thing is not to confuse them in terms of connections with streams.

How to dismantle an old calculus device?

First, you need to turn off the valve on the riser outlet and open the valve on the mixer to release the pressure. It is very important to take into account that when removing the old water meter, residual water will flow out of the pipe, so it is better to immediately prepare rags. If the previous water appliance has functioned sufficiently for a long time in the system, then installation problems may arise due to rusted parts. In such situations, I can advise tapping with a hammer the soldering points or heating of all joints.

Advice! If all else fails to dismantle the water meter yourself, you can cut the pipes. But these are extreme measures.

Additional fittings

One of the conditions for the functioning of the hot and cold water meter system is the presence check valve... If the manufacturer has not added it to the component, then it is imperative to purchase it additionally. Unfortunately, some houses do not have a shut-off valve, which is very important. After all, we need to somehow block the riser.

In the event that the apartment does not provide for the presence of a purification filter, replacing the meter is a good prospect for their installation. This filter is able to protect the device from damage.

Advice! I can advise the most the best option cleaning - these are filters for old pipes.

The main problems that can arise during the process

The main situations that can complicate the process have already been described a little above, but I can say with confidence that problems also appear from nowhere. It will be very disappointing when a shortage of any small parts, without which the optimal replacement cannot be carried out. After all, until you find them, the apartment will remain without water supply.

Advice! To avoid such situations, you need to think about everything in advance.

Commissioning

After you have installed the equipment, seals should be installed immediately. To do this, you need to apply to the water utility for their specialist to check and draw up an act.

Important! It is worth keeping the data sheet for the entire working period of the meter, because it can be asked for presentation at any time.

Copying of materials is possible only with an indication of an active, not closed from indexing link, to the source.

Cold and hot water meters that are installed in an apartment have their own operational life. If there is no mechanical damage, then the cold water meter is designed for 5 years of operation, and the hot one - for 4 years. After the end of this period, the water meter requires verification or replacement with a new device. Management companies strictly monitor compliance with these rules and require replacing the water meter according to the expiration date without fail.

Self-replacement of water supply meters is not a complicated procedure, however, it is advisable to clarify in advance the possibility of its carrying out in the relevant services. Quite often, these companies insist on replacing water metering devices by their specialists, since this service is paid and due to the proceeds from its provision to consumers, you can significantly replenish the organization's budget. At the same time, from the standpoint of a water consumer who has the ability to independently replace the meters, these are unnecessary expenses that can be completely avoided.

DIY step-by-step instructions for replacing the meter

First you need to turn off the water (a tap is installed in front of each water meter). You do not need to call the ZhEK employee - do it yourself.
The absence of water in the system must be checked on any mixer. If the water from the tap continues to flow, then in addition to the water meter, the shut-off tap must also be replaced.
Even if the tap is turned off, there is residual water in the pipes. In order to remove them after removing the counter, you should prepare rags in advance.
The old water meter can now be removed using the tap.
On the squeegee, unscrew the nuts (unscrew the hinged nut counterclockwise).
After removing the counter, you should remove the old gaskets, and then cleanly clean the ends of the squeegee from possible remnants of rubber stuck from the gaskets. Cleaning can be done with a regular knife or screwdriver.
The new meter is installed in place of the old one, and for high-quality sealing of the connections we use paranitic or rubber gaskets. The thread of the water meter does not require additional sealing, as this will only complicate the tightening of the nut.
Please note that the device must be installed in the direction of the water flow (an arrow is drawn in the required direction on the body of the water meter for orientation).
After that, we install gaskets between the squeegee and the counter, tighten. For convenience, we hold the water meter with one hand so that it does not scroll. It is not worth tightening too much, it is better to tighten it additionally later than to spoil the gasket.
Now you can open the shut-off valve and make sure that the connections are reliable and tight (the valve on the mixer opens all the way).

Features of replacing the hot water meter

Performing the same manipulations that were listed above, you can replace the hot water meter, while taking into account some of the features. This meter differs in body color from the cold water meter (it is important not to confuse these devices during the installation process). It should be noted that sometimes slightly warm or even cold water is supplied through hot water pipes. In this case, the water meter will consider it as hot, at the appropriate rate. Therefore, in the process of selecting, replacing and installing a new measuring device for hot water, you should follow the recommendations of a qualified specialist. A filter, special fittings with union nuts and gaskets are included with the new device to ensure the tightness of the connections.

In conclusion, I would like to note that it is much more advisable not to buy cheap water meters of dubious quality, but to opt for more expensive and high-quality products. This will protect you from the need to change your water meters frequently due to constant breakdowns.

How to replace a water meter if the old one is out of order. My advice is to buy high-quality metering devices, so as not to replace them often, a high-quality one is more expensive, but it comes out cheaper, because you do not need to change it so often.

The replacement procedure is technically very simple, no special skills are required, you need to be a little able to tighten and unscrew the nuts, and you can do it easily yourself.

Step-by-step instruction

First, turn off the water. You will need an adjustable wrench and possibly a pipe wrench to hold it if the nuts are "stuck" to the meter. Several times I had to anneal the nuts, annealed them with gas, since it was unrealistic to unscrew them. If you have such a situation and you will be warming up, then be sure to repack all the connections again !!! We unscrew the nuts counterclockwise, take out the old meter, be sure to clean the fittings from the remnants of old gaskets, insert new ones, I always put silicone or, in extreme cases, rubber. Do not put paranitas, they stick to it within 2-3 years and are hard to unscrew. Then screw them onto the new device by hand until it stops, take an adjustable wrench and tighten the nuts 0.5-1 turn, while holding the counter by the body with the other hand. Turn on the water and see if it drips somewhere, tighten the nut a little. That's the whole procedure. You can invite a sealer.

It is also desirable immediately. When installing the meter, do not mix up the direction. The arrow shows the direction of the water. Do not wrap tape or flax onto the threads, only gaskets. I think, after reading this article, you will not have a question how to replace these metering devices !!! If you have, ask in the comments, what I can, so I will help.
