Installing water meters is the procedure. Rules for the free installation of water meters. Scheme with pressure reducer

Do-it-yourself installation of water meters is a current issue. On July 1, 2013, the law on mandatory installation water meters, and now every consumer, whether you like it or not, will have to acquire cold and hot water metering devices. True, many have already installed them a long time ago - the savings are immediately visible and tangible in the budget.

Those who hoped for a chance and do not know how or do not want to work with their hands will now have to fork out: plumbing firms and individual masters immediately raised prices for work, referring to the large flow and urgency of orders; there is nothing to object. So it makes complete sense to learn how to install water meters yourself. Putting the meter on the water yourself is a simple matter, walking through the authorities takes more time.

Which meters to choose?

The best option: turbine (with an impeller) mechanical - cheap and cheerful. An electronic meter may be “cool”, but only electronics tend to break down, and replacing water meters in an apartment means, in addition to expenses, a new circle of overcoming bureaucratic formalities.

Meters for cold and hot water need different design. This is immediately evident upon purchase: they are marked with blue and red belts, respectively. If put on cold pipe"hot" counter, there will be no trouble, but "hot" is more expensive. Guess what will happen if hot water to put a counter for a cold one is pointless, this option will simply not be allowed for operation.

You need to buy regular apartment meters water without chasing something exceptional. Water control metering devices are subject to mandatory certification. Since it is on sale, it means that it has passed certification. And after verification and sealing, you are no longer responsible for it, unless you accidentally broke it.

When buying a meter, make sure that it is fully equipped: the kit must contain strainer, two connectors with nipples, union nuts and gaskets, and a non-return valve. Unscrupulous sellers (individual traders in the "iron" markets often sin with this) happen to dismantle meters and sell components separately, so it's better to buy meters in a specialized store.

Next important point when buying a counter - his passport. It must be printed in a typographical way, sealed with a factory stamp, and the serial numbers in the passport and on the product must match. A counter with a photocopied piece of paper, even if they didn’t give you substandard, they will actually accept it, but you still have to pay.

In my private house, wiring was made for the garden and the house ..., that is, there is a house for the house, and a water meter for the garden. I used this scheme for almost 10 years. By the way, I naturally coordinated this scheme for connecting water meters in Vodokanal. The inspector came, checked everything, installed the seals, and for so many years everything was fine. Now, with the next replacement of the water meter (the service life has expired), they force me to redo the water meter connection diagram ... We found those conditions for ... 1982 (!) ... .. there the water meters must be connected IN SERIES. That is, the first water meter is considered the main one, from it water is coming in the house and after it there is a second water meter, which counts the water for irrigation. What's the point???? I have to subtract from the readings of the first device the readings of the second ... ..

From our riser the apartment of the next entrance is powered. And so it is throughout the house. When installing meters, we will also pay for a neighbor. How and through whom will he issue the “technical impossibility” of installing meters? What rates would you have to pay then?

landlord or country house he decides how to install a water meter - on his own or using the services of a specialized form. Legislative rules installing water meters in an apartment does not prohibit installing a water meter with your own hands. However, a preliminary check and sealing of the device after installation is mandatory requirements. Otherwise the data home appliance accounting by the water utility will not be taken into account.

Experts have a lot of disputes regarding the advisability of installing water meters in an apartment: in some cases, installing a water meter is economically beneficial, and in other situations, on the contrary. However, all arguments are not particularly significant, since the installation of water meters is mandatory from July 1, 2013, which means that each consumer needs to install a water meter: cold and hot.

Varieties of water meters

There are several options for water meters on the market for water meters. There are no regulations on how a water meter should be arranged by hand, so the choice of the type of device is up to the consumer. In the video you can see how a standard water meter works:

Regardless of the principle of operation and design, these devices have some characteristic features:

location of the water meter - there are models designed specifically for vertical and horizontal pipelines, as well as universal devices for installation in any position;
the diameter of the connecting pipes must fully correspond to the diameter of the pipeline, as a rule, these are models of the Du15 series;
ambient temperature - theoretically, hot meters can be installed on a cold pipeline, the main requirement is that the water temperature does not exceed the maximum allowable value.

All water flow meters are divided into non-volatile and requiring the connection of an electricity network. The first type includes simple and reliable mechanical impeller meters. When the flow of liquid passes through them, the blades rotate, counting the number of revolutions.

The device of volatile water meters is somewhat more complicated, and can be performed in one of the following options, depending on the principle of operation of the device:

vortex - the product counts the vortices that are formed when the water flow passes through a special element inside the device;
electromagnetic - the flow rate is calculated when the flow is affected electromagnetic waves. These devices are very sensitive to the composition of the water;
ultrasonic devices use sound waves of a certain frequency to determine the flow rate.

It is also worth noting that if the counting mechanism is isolated from the flow of water by a special partition, then such products are called “dry”, and models with non-isolated counting mechanisms are called “wet”.

Where can a water meter be installed?

Before installing the meter, it must be borne in mind that certain requirements are put forward for the installation of the device, regarding the installation site. These requirements are common for both apartments and private houses:

temperature not less than 5°C;
the presence of natural or artificial lighting;
access for inspection, maintenance and repair.

If a fire drainage system is provided in the room where the water meter is planned to be connected, then a special valve must be installed on the bypass pipe, which must also be sealed with a water utility. According to the rules, the installation of this valve is a duty fire service who need to be invited for this in advance. However, their official permission for this operation is not required, so you can buy and install the valve yourself.

What if DHW system made according to two-pipe scheme, then this is another point. This phenomenon is rare in apartments, but their residents are very familiar with what elevator unit in the living room. Installing a hot water meter in such housing will require the additional purchase of a bypass valve for circulation pipe, otherwise the device will "twist" a lot and constantly.

The procedure for how to properly install a water meter is the same for all types of this product. For apartments, there is one rule - the meter must be installed as close as possible to the entry point. As a rule, the water meter is installed in the bathroom, in individual cases allow installation in the bathroom.

The installation of a water meter in a private house should be no further than 20 cm from the input. When constructing a well, its cover is equipped with locks and sealed immediately after the device is sealed. It is allowed to open it only in exceptional situations - in the event of an accident or fire.

Preparatory measures for installation

Any metering devices should be bought in specialized stores, and not from hand or on the market. At the same time, when buying, you need to check the complete set of the product, the availability technical passport, and also check the number indicated in the document with the number on the device itself. So you can be sure that you have purchased certified products that are suitable for use.

After the purchase and before putting the meter in the house or apartment, you need to take it along with the accompanying documentation for verification to the state office of instrumentation (KIP) of the housing office or to the water utility department. It is not forbidden to use the services of private firms to check the operation of metering devices, however, the company must be licensed.

After verification technical product a stamp will be put in his passport, and after installing the meter on the water, a seal will be installed on it, which absolutely cannot be damaged or removed, otherwise there will be problems with registering the device. After checking the meter, you can begin to develop a water meter connection diagram and prepare for installation.

Meter installation specialists advise preparing everything in advance necessary tools and materials for installation work. First of all, you need to purchase paronite gaskets for the hot pipeline and rubber gaskets for the cold one. Also, most likely, special sealing pastes and sanitary tow will be required, or synthetic threads which already have silicone grease in their composition.

Set the right tools depends on the type of pipeline, a certain section of which will have to be cut, so you will need a hacksaw for metal or a saw for plastic. You will also need:

prepare a tool for cutting threads on metal pipes to install a block of meter and nozzles;
buy scissors for cutting, connection fittings and a special soldering iron if the pipes are made of plastic.

In addition, you will need cap and wrenches appropriate diameter for tightening connections. In this case, it is important not to overdo it so as not to “tighten” the installed threads.

To check the complete set of the device, it is necessary to decompose into flat surface all elements of the block in the direction of water flow:

A shut-off valve (if included) allows you to shut off the flow at the right time. A valve is also required to regulate the water supply.
Mechanical filter for insoluble impurities and filter coarse cleaning water from debris. Able to extend the life of the meter, installed in front of the device.
The first connecting pipe (with a union nut - American).
The water meter.
The second connecting pipe.
A non-return valve that retains water in the system prevents the impeller from turning back when the water supply is turned off.

When laying out the elements of the metering device block, you need to pay attention to the arrows that indicate the direction of flow. All arrows must point in the same direction. Before you install meters for hot and cold water yourself, you must turn off the water supply. AT apartment building it will be necessary to block the entire riser, which only public utilities have the right to do.

Do-it-yourself water meter installation

Do-it-yourself installation of water meters is quite possible. You will have to install the device yourself and call a representative of the Housing Office to seal it.

The sequence of work when installing water meters in an apartment with your own hands:

It is better to start the installation of a device for measuring water consumption with a “dry assembly”, in order to count all the turns before installation in the system and note on which of them the circuit element takes the desired position. Then the structure is disassembled and connected again using gaskets or winding. When the pipeline is in a horizontal position, the circuit looks like that the handle of the valve or faucet and the digital panel of the device are directed upwards, and the filter sump and impeller are directed downwards.
The next step is to remove part of the pipeline to make room for the tie-in block. It is important to measure the length of the assembled "chain" of block elements as accurately as possible and measure the corresponding distance on the pipe. Before cutting out a section of the pipeline, it is worth substituting a container under the disconnection points so that the liquid remaining in the system does not leak onto the floor.
The meter is mounted on a metal pipeline on a pre-cut thread. FROM plastic pipes installation work is easier to carry out - it is enough to connect the device to the pipeline with special fittings.

To check the quality of the installation of the water meter, you need to resume the water supply, then smoothly turn the valve or tap lever and carefully inspect assembled structure for the absence of leaks.

If the operation of the unit is beyond doubt, then an authorized person should be invited to inspect, check and seal the water meter. After the representative of the water utility or utility service makes all the necessary marks in the passport of the device and issues an appropriate document that confirms the fact that the water meter has been put into operation, the consumer will be able to pay for water supply in accordance with the flow.

How to submit evidence?

In order to monthly pay the bill for the actual water consumption and sewerage fee, it is necessary to transfer data from the meter to the appropriate service every month. In each region, this procedure is implemented in one of the following ways:

the completed leaves of the subscriber book are torn off and lowered into special boxes;
water meter readings are entered on the website of the water supplier in personal account consumer;
an e-mail with the data is sent to a special e-mail of the organization.

Vodokanal or DEZ may also develop other methods for transmitting meter data. But the consumer chooses the option that is most convenient for him.

Now you know how to properly install the meter for cold and hot water with your own hands, taking into account the features of the device and installation requirements.

Do-it-yourself water meter installation - step by step instructions

Despite the fact that the cost of housing and communal services in different regions countries may differ, the fact that the price is constantly growing is beyond doubt. And if a few years ago people agreed to pay the “average” cost, now this does not suit them, they want to pay money only for the water that was used. To do this, they are installed on underwater highways. They must be sealed by employees of the managing company, otherwise the water meters will not be valid.

You may be interested in information on how

An additional incentive to buy water meters is that soon the government intends to supply every user of the water supply with them (of course, at the expense of the buyer). In a word, sooner or later, but you will have to install a water meter. We have already talked about that earlier, and today we will focus on its installation.

The feasibility of installing a meter

If you are in doubt whether a water meter will help you save money or, on the contrary, will lead to unnecessary waste, then first weigh the pros and cons of installing measuring equipment.

For example, if two people live in an apartment, and five are registered, then the fee will be based on the “average” consumption per month for each registered tenant. This is unprofitable, because if you consumed, say, six cubes, then you will need to pay for all twenty. Then it will really help you significantly reduce your water bills.

If the same number of people actually live as registered, then installing a water meter will save up to 30%.

Are there cases when it is unprofitable to install a counter? Yes, they are. We are talking about situations where the apartment lives large quantity person than registered. For obvious reasons, it is better for such people to pay for "average" consumption.

Legal side of the issue

There are no clear prohibitions on self-installation of water meters in the legislation, so if you have the desire and opportunity, then why not? True, there are several important nuances here:

Consider all these points before proceeding with the installation.

Rules for installing a water meter yourself

The installation of the meter begins with contacting the local water utility, where you will be given technical requirements to the water meter. This is followed directly, certified and with an imprint on the seal.

Important! Be sure to check the meter after purchase by contacting a private licensed company, a water utility or housing office!

The meter should be checked at the KIP department of the local water utility, or a similar department of the housing office. It can also be done in private company licensed. The counter is handed over together with the registration certificate, in which, after the end of the check, the corresponding stamp of the department will appear and all the necessary fields will be filled in. Here you will be assigned the date of sealing.

Important! Do not damage the KIP seal. Such a meter will not be accepted in the water utility. If the factory seal is damaged, then the device can be accepted into the instrumentation, and if there is no instrumentation seal, then the meter data will be invalid.

Choosing a place for a water meter

You need to install the meter as close as possible to the place where the line enters the room. There are no specific numbers here, since the input places in various buildings may differ significantly. The inspection will be carried out by the inspector, but you can do it earlier. The best option for a city apartment is a place near. It happens that pipes run along the floor through the toilet, then you cannot hide the traces of the installation, and the meter will have to be installed in the bathroom.

Another thing is private houses, for which the inspection requirements are much stricter. The water meter is installed no further than 20 centimeters from the outlet of the pipeline. If there is a well in the yard, then it must be capital and locked with a reliable lid (it will also be sealed). Only the inspector has the right to break the seal, an exception can only be in the event of a fire or emergency at the water utility itself.

What accessories are required for installation

If you install the counter according to the scheme, then no difficulties will arise. But in order to understand this, you need to clearly understand the purpose of each node.

Important! A half-open position for a ball valve is a sure way to an early failure. It should only work in the "Open" and "Closed" positions. If partial water shut-off is required, install a valve.

Water meter installation technology

When everything you need has already been purchased, read the instructions for all items. The data sheet of the meter must indicate what distance straight cut must be in front of and before the appliance. The installation procedure consists of the following steps.

Stage 1. First, lay out all the details in a line so as not to get confused later: check valve, water meter, filter and stopcock. There are arrows on each part, pay attention to them - they should all point in one direction.

Stage 2. Next, make a "dry" connection, necessary in order to correctly calculate the turns. Screw the filter onto the faucet and count the turns, usually no more than five. Pay attention to which of the turns the sump is at the bottom - for example, on the fourth. You unwind everything, take a seal (you can use ordinary linen tow) and wind it around the stopcock filter.

In addition to tow, as a sealant threads made of polyamide "Tangit Unilok", which additionally contain silicone grease, as well as sealing pastes "Multipak" and "Unipack".

You do it like this:

take one strand of tow, align it and make it an even cord with a thickness of no more than 1 millimeter;
wind it on the thread so that all the grooves are closed;
apply plumbing paste on top and tighten the stopcock (the main thing is not to overdo it so that the connection does not burst).

Stage 3. Often, American women and sealing rings come with water meters. Americans (special pipes with union nuts used to connect pipes) will do, but you buy new rings. If the meter is installed for, then it is better to use paronite gaskets, and if for cold, then rubber. Screw the pipe onto the filter using the same linen tow, then the counter. Connect the other pipe to the check valve.

Attach the entire structure to the water meter. You will get the following:

shut-off valve switch “looks” up;
the dial of the counter is also up;
filter sump - the same;
impeller - down.

Stage 4. All elements are connected, now they need to be cut into the pipeline, having previously blocked the water.

Important! If the house is an apartment building, then you can’t do it yourself - you need to call a representative of the water utility.

Measure how long the structure is. Measure the same distance on the pipe from the joint. Cut off the required area, after substituting the basin (perhaps the water will flow, although not under pressure).

Stage 5. Fasten the structure to the supply pipe. Some problems may arise here. If the pipeline is metal, then you will need to cut the thread, but that's not all. The most important thing is to measure the distance correctly, because it is not plastic and will not bend. It is advisable to replace the entire area polypropylene pipes, then special fittings will be required to connect plastic to metal.

System check

After completing the installation, you should check how efficient the system is. To do this, turn on the water and slowly unscrew the ball valve. See if there are any leaks. If the system is in order, the meter measures correctly, there are no problems, then the question arises, feel free to call a representative of the water utility. He will inspect everything, make the necessary entries in the data sheet and put a seal. In some cases, a seal can also be placed on the filter, but this is done just like that, just in case, there is no particular need for this. How are they installed , you can read in our article.

As a result, you receive a technical passport and a document certifying that the device is sealed and put into operation. From now on, you will pay for water supply services in accordance with the readings of the device.

As a conclusion

As we see self-installation a water meter does not require much time or effort. The main problem is the bureaucratic ups and downs, obtaining and approving various papers, filing applications, etc. Do not forget that periodically you must take the water meter for verification, because it may count incorrectly and then it is produced. If the water meter is for hot water, then this should be done every six years, and if for cold water, then once every four years.

The installation of individual and common house metering devices for the consumption of cold and hot water by residents can significantly reduce the cost of paying for housing and communal services. With this approach, it makes sense in the reasonable use of water, because the amount of the amount indicated in the receipt will directly depend on the number of saved cubic meters. The widespread use of water meters also disciplines the employees of water utilities, as it becomes impossible to uncontrollably write off losses from the operation of worn-out networks on ordinary water consumers. The regions have developed rules for installing water meters, which specify the requirements for organizations involved in the installation of these metering devices, as well as the procedure for commissioning installed water meters. If you want to install the meter with your own hands, then first consult with those who seal the water meters about the possibility of self-installation.

The video below will be of interest to those who decide to personally understand the installation features of this type of equipment. In the video, the master talks in detail about how to install water meters on your own.

How to prepare a water meter for insertion into a pipe?

Before installing the water meter, it is necessary to connect a coarse filter to it. This device will protect the water meter mechanism from large particles of debris, the ingress of which can shorten the life of the device.

In addition to the filter, it is necessary to connect a check valve to the water meter, which acts as a protection against rewinding readings. For availability check valve water utility inspectors pay attention and do not accept the device into operation without this plumbing device.

Together with the water meter, a coarse water filter and a check valve are installed, which prevents the meter reading from being unwinded.

Together with the meter, union nuts (American) should be included in the kit, allowing, if necessary, to remove the meter without harm to pipes and other elements of the plumbing system. The tightness of the union nuts with the check valve and the filter is ensured with the help of FUM tape or tow.

At self assembly of the water consumption metering unit, it is necessary to follow the direction of the arrows placed by the manufacturer on each component. Marks in the form of arrows show the direction in which water should flow through the meter. The American is screwed to the filter from the side of the sharp end of the arrow, to the non-return valve - from the reverse side (the tail of the arrow).

If you confuse during assembly the direction of the arrows on the filter, the check valve and the water meter itself, then you will not be able to seal the meter. The representative of the water utility will check the correct installation of each element of the block

On the water meter, the manufacturer also indicates the desired direction of water with an arrow. If you ignore this mark, then the correct operation of the device cannot be guaranteed. Depending on the design of the water meter, the water supply to plumbing fixtures may stop altogether. The arrow on the device must be oriented in the direction from the shut-off valve embedded in plumbing riser. The instructions attached by the manufacturer to the water meter indicate the connection diagram of the water meter to plumbing system. When self-assembling, these recommendations should be taken into account.

How to install a meter in a water supply system?

The easiest way is to install a do-it-yourself water meter in a water supply system made of polypropylene or metal-plastic pipes. Polypropylene is easily cut special tool or ordinary kitchen knife. Connection of elements polypropylene pipeline carried out using a compact soldering iron, the technology of which is quite simple. Installation is carried out in the following order:

Cut the pipe and connect to the cut-off faucet a pre-assembled water meter block. The tightness of the connection is ensured by winding the FUM tape or tow.
After the operation for the capital connection to the counter tap is completed, they begin to measure the exact location of the mating thread.
The excess pipe is cut off and a thread is cut at the end or a special fitting is installed. The connection of polypropylene parts is carried out using a soldering iron.
Then, the non-return valve with a screwed American is disconnected from the assembled water meter and screwed onto the prepared thread.
After that, the connection of the union nut (American) with the meter is restored.
Open the tap that cuts off the water supply system of the apartment from the riser, and check the tightness of all threaded connections made during the installation process.
In the absence of leaks, we can assume that the installation of the water meter was successful.
It remains to wait for the inspector of the water utility, who will arrive at the request for the facility and seal the meter.

Work on inserting a water meter into a metal water supply system is much more difficult, since cutting a pipe will require a saw and a machine with which threads are cut.

Criteria for choosing a company for installation

If you plan to attract a specialized company to perform installation work, then take the choice of contractors seriously. About the seriousness of the company says:

have a license for this species works, which guarantees the professionalism of employees and the equipment of the organization with the necessary equipment;
providing the client warranty service installed equipment and its free repair (replacement) in the event of a breakdown during the warranty period;
documentation of work (installation contract, certificate of completion), facilitating the registration of the device and its registration, as well as service maintenance.

A company that has passed the procedure for licensing activities for the installation of water meters is responsible in accordance with the contract for the correct installation of water meters and their suitability for operation. The company's specialists will develop a water meter installation scheme, in accordance with which all work will be performed. A list of verified companies can be obtained from the Single Customer Directorate (DEZ).

When contacting professionals, you do not need to rack your brains over how to put water meters on. Specialists will do everything quickly and in accordance with the requirements of regulatory authorities.

What documents should you have on hand?

After the installation of the water meter is completed, the three parties draw up an acceptance certificate for the installed water metering unit.

This document indicates the serial numbers of metering devices, the date of their installation, data on the water consumer, representatives of the installation company and DEZ. The act is signed by all parties. In addition to the act, the tenant must have:

technical passport for the water meter, which indicates the primary value of the flow, as well as the date of installation and commissioning;
certificate of verification of the water meter, which indicates the date next device testing (depending on the model, subsequent verification is carried out after 4-6 years);

For verification, the device is dismantled and transported to a specialized company. This work you can entrust the installation company, which will carry out service maintenance of the meter, and monitor compliance with the verification deadlines.

This is what the procedure for installing water meters looks like. Depending on the policy of the regions, there may be minor deviations from the described mechanism. Licensed specialized companies will save you the hassle of installing metering devices. In this case, you do not have to think about how to seal the water meters, because the company you hired to carry out the work will think about all this.

According to the adopted law, all homeowners must install water meters in their homes. Deadlines are constantly shifting, but sooner or later they will have to be set. There are a decent number of organizations that can do this for you. For a fee, of course. Some operational campaigns offer to do this for free and are even ready to provide a counter. But the bills for these water meters are cosmic - the figures are too high. Therefore, installing water meters with your own hands is the best way out if you do not want to pay the company for services.

Beneficial or not

You don’t have to think about whether you need a water meter or not - a law has been passed according to which everyone is required to install it. But many are wondering how profitable it is. If the apartment is home to as many people as registered or less, installing a meter is beneficial. It is also beneficial if, say, someone moves to a dacha for the summer or spends a vacation there. If the situation is diametrically opposite - fewer people are registered than live, it is not profitable for you to put a counter. But there is no getting away from this.

How big will the savings be permanent residence depends on the calculation method adopted in your management campaign and how intensively you use water. At a minimum, you will save about 30%, but there were cases when payments after installation decreased significantly. This may be if the house is general appliance accounting. In this case, according to the results of the month, the consumption of those residents who have meters installed is deducted from the total readings, and the remainder is divided among the remaining apartments according to the number of registered people. Usually those who actually live do not put meters more people than prescribed. In this case, the monthly consumption per person can be 8-10 cubic meters of cold and about the same amount of hot water. In fact, even if you do not save much, it turns out about 3 cubes of cold and 2 hot. So it really does make sense.

Install on your own or through a company?

Under current legislation, the installation of water meters is at the expense of the homeowner. That is, you must buy a meter, install it at your own expense. The installed water meters are sealed by representatives of the water utility or the DEZ free of charge.

Self-installation procedure

Self-installation of water meters is possible. Nobody should object. You just have to do everything with your own hands - and install the meter, and call the representative of the Housing Office to seal it. What you need:

All paperwork is reviewed and completed. standard contract, you sign it, on this it is considered that you pay for water according to the meter.

How to hire a good firm and what they should do

There are two ways to find a company that installs water meters: take a list in the DEZ or find it on the Internet yourself. The list will already include firms that have licenses, but obviously not all that work in this area. On the Internet, it is necessary to check the availability of a license. A copy of it must be posted on the site.

Then, in any case, you should read the standard contract that the company will conclude with you. It should contain a complete list of services. The conditions can be different - someone provides their counter, someone puts yours, someone comes with their spare parts, someone works with what the owner has. By combining the list of services provided and make a choice.

Previously, there was a clause in the agreement after-sales service and without it, firms did not want to install meters. Today, this item is recognized as illegal, since it is not necessary to actually service the meter, and it should not be in the clause, and if it is, you have the right to refuse these services and not pay for them.

Preparing for installation

If you have chosen a different campaign, you must leave them an application. There are two options - some firms accept applications on their website and may even offer a discount for this, while others prefer to see you in the office and sign an agreement.

In any case, first a campaign representative arrives (you agree on the date and time of arrival), inspects the “field of activity”, assesses the condition of the pipes, takes measurements, and often takes photos of communications. All this is necessary in order to be able to develop a meter connection diagram and quickly assemble it. Then you should call and clarify the date and time of installation of the water meter. In this conversation, you need to find out who is negotiating the shutdown of the risers with the operational campaign. Normal firms take it upon themselves.

Installation of water meters by campaign representatives

At the appointed time, a campaign representative (sometimes two) arrives and does the work. In theory, they should agree with you what and how to put, but this does not always happen. At the end of the work (usually takes about 2 hours), they issue you a certificate of completion and special paper on which the factory numbers of metering devices are written. After that, you must call a representative of the govodokanal or DEZ to seal the meter (in different regions they do this different organizations). The sealing of counters is a free service, you will only need to agree on the time.

In the act that you were given during installation, the initial readings of the meter must be entered (they are different from zero, since the device is verified at the factory). With this act, a photocopy of the organization's license and your water meter's passport, you go to the DEZ, sign a standard contract.

How to transfer data

You will need to submit monthly actual consumption data. In different regions, the procedure is implemented in different ways, but basically there are several ways:

leaflets torn off and filled out from the subscriber book are lowered into special boxes;
leave data in the personal account on the website of the water supply organization;
send e-mails with testimonies to a special address of the organization.

There may be other ways - each water utility or DEZ develops them on its own. If there are several ways, you choose the one that is easier for you.

Water meter readings can be uploaded to the campaign website, to their email address or tear-off vouchers put in a special box

Water meter installation diagram

It doesn’t matter if you install the meter through a company or do it yourself, you need to know how it should look like correct scheme- It is very desirable to control the process.

Where and how to put: choosing a place for a water meter

They put meters immediately after the riser in a straight section to the first branch to plumbing fixtures. There are water meters, the installation of which is possible only in a horizontal position, there are models with the ability to vertical installation. Just keep in mind that in a horizontal position, the accuracy of the device is higher than in a vertical one and it is not a fact that it will count less. So it is highly desirable to find a way to put it "lying".

What and why should be in the scheme

The standard scheme for installing a water meter looks like this:

Now more about what each element is needed for.

A ball shut-off valve is needed to turn off the water if necessary - fix the mixer, clean the filter, change the meter, etc. Therefore, its presence is mandatory. It must be placed so that it is convenient to turn the valve.

The coarse filter captures the largest particles that are in the water supply. It must be placed so that the outlet is directed downwards. Otherwise, it will clog up quickly.

All of these elements often internal thread. So that they can be connected to each other, connecting elements are used, which are often called "drives". They are on both sides external thread and small plot a flat pipe (in some cases, only a few millimeters at all). With their help, everything is connected to each other.

Optional Schema Elements

Often a check valve is placed after the counter. It is required so that in the absence of analysis, the water does not go in the opposite direction. It also eliminates the increase in reading in the presence of unstable pressure.

He also cuts off two more unpleasant situations: and does not allow cold water to flow from one pipeline to another. This happens if someone has a hygienic shower installed on the riser (on the toilet or bidet), a shower cabin with cheap faucets. They do not have non-return valves and such overflow is possible.

Scheme with check valve

If the pressure of cold water is higher than that of hot water, then cold water reduces DHW temperature, and in the opposite situation, hot water can come out of the cold water tap. Therefore, the installation of a check valve for both cold and hot water is highly desirable, but not required.

Sometimes, after the check valve, it is recommended to install another shut-off valve. It is needed so that when removing the meter or when cleaning the same filter, water from the pipes in the apartment does not drain to the floor. In principle, you can substitute a container, but this is not always possible. Water is in the pipes ordinary apartment about 6 liters, collecting from the floor is not the most pleasant experience. But this strapping element is placed or not at the request of the owner.

There is another device that can be installed - a pressure reducer. It stabilizes the pressure in the system, extending the "life" of the entire household appliances and faucets/faucets. Placed after the coarse filter. Not the cheapest thing, but very useful.

Some subtleties and nuances

When buying a meter, you need to make sure that the number in the passport matches the number stamped on the water meter. The device must also bear a sign that it has been certified. The passport must have a stamp with the date of factory verification. The "fresher" the date, the better - the more likely it is that you will not be forced to verify it before installation. Another necessary detail is a store record of the sale with a seal. In the event of a meter malfunction, you will be issued an act with which you can demand its replacement.

It is also very desirable that the factory verification date be “fresher” - you will not have to carry the device for verification longer.

Mounting Features

When installing water meters, all threaded connections it is necessary to seal - the pressure in the lines is serious. For this, linen winding or fum tape is used. If you use winding, winding it on the thread, it is advisable to lubricate it with packing paste - it will be easier to work. Fum tape does not need lubrication, it is elastic itself.

One important point: when tightening the connections, do not use excessive force - microcracks may appear, which will then lead to leakage of the connection.

If you go from the outlet of the riser steel pipes, you will need welding or a grinder to cut off a piece now unnecessary. You will also need to cut the thread at the end of the pipe (if not) - this is the only way to connect the stopcock. On the reverse side, the situation is the same - either a transition fitting or threading is required.

Flow direction

When assembling all parts, please note that there is an arrow on the body of each. She may not be except for ball valve, since he does not care in which direction to pass water. Although, if installed incorrectly, you will have to turn the knob in the other direction, but this is not fatal. For other devices - a meter, a filter, a check valve and a reducer - the direction of flow is critical. Therefore, when assembling, set them so that the flow of water goes in the direction of the arrow. This is really important.

If there is no arrow on the body of the listed parts, most likely you have the cheapest and possibly low-quality part. If possible, it is better to replace it with a normal one, if not, find out the direction of the flow yourself, having examined the structure, you can understand where the flow should go.

As you can see, do-it-yourself installation of water meters is real, but there is enough a large number of features. And one more thing: when you agree on turning off the risers, ask not for two hours, but rather for four. And pre-assemble everything without winding, measure the length, figure out where and how to place everything, draw where you cut, weld, put retaining clips (if the pipeline is from), etc. In general, spend the maximum preparation. In this case, self-installation of water meters will take place with a minimum of hassle.
