Installation of water meters in the apartment. Do-it-yourself water meter installation How to install a hot water meter

Centralized water supply pipelines passing through an apartment or across a territory near a private house are the property of the owner of the dwelling or personal plot. Therefore, when you need to install water meters, you can easily do everything yourself and not take any permits. But along with the right, there is also responsibility: the procedure must be carried out in compliance with the requirements of the law and applicable regulations. Let's look at how to install water meters and draw up paperwork correctly in order to get registered with a local water utility.

Procedure

First, a few words about whether it is necessary to install water meters. We answer immediately: no, not necessarily. But the presence of flow meters officially registered with the management company provides undoubted advantages:

a clear scheme for calculating the cost of services: monthly cubic meters consumed are multiplied by the current tariff;
the opportunity to save money through the careful use of water and serviceable plumbing fixtures(without leaks);
no need to pay money when in fact there is no consumption of hot and cold water during your absence.

Reference. If water meters are not installed in the dwelling, then the supplier organization charges payment at standard rates. According to statistics, a family of 4 people spends on average about 7 m³ per 1 month, and according to the norms, you have to pay for almost 12 cubic meters. That is, accrual by metering devices is more profitable.

The procedure for self-establishment of water meters is divided into the following stages:

Visiting the management company to obtain technical conditions.
Selecting a meter and purchasing related materials.
Do-it-yourself installation and connection of a water meter assembly.
Sealing the device and registration with the fixation of the initial readings and the conclusion of the contract.

Contacting the local water utility

This step must be done before purchasing and installing water meters. Why is this course of action important? Firstly, the management company is obliged to provide its requirements for the metering device and its installation scheme. Secondly, you or your apartment may belong to the preferential category of subscribers for whom meters are installed free of charge.

Advice. In some cases, representatives of the supplier organization forbid residents to install water meters on their own and impose services various firms. Remember that this type of activity does not require a license and you have every right to mount the water meter in any suitable way.

On the technical side, water utilities in different regions and cities may put forward the following requirements:

put the device model with additional features– with impulse signal transmission or taking into account hot water at different rates depending on the temperature;
mandatory introduction of a separate check valve into the circuit;
instructions on the location of the metering unit and the possibility of access to it.

Armed with comprehensive information from the management company, proceed to the purchase of components.

There are 4 types of devices that record the volume of flowing fluid per unit of time:

mechanical type (tachometric);
electromagnetic;
vortex;
ultrasonic.

For commercial accounting of water supply to apartments and private houses, the first variety is usually used - tachometric water meters. They feature a robust and cost-effective design that meets accuracy requirements.

Mechanical water meter device

The principle of operation is simple: the flow of water rotates the impeller, and it rotates the digital sections of the flowmeter through a system of gears. It makes no sense to consider other types of devices, since they are rarely used in private homes due to the high price.

When choosing an apartment or house water meter, consider the following recommendations:

Don't buy too cheap products. good device must serve at least 12 years and during this period at least twice pass the verification.
Do not forget that different units are needed for cold and hot water (in the latter, the mechanism is designed for contact with water up to 100 ° C, and in "cold" - up to 40 ° C). There is an option to purchase universal water meters, but they are more expensive.
The passport must contain the product number that matches the inscription on the case, and the value of the calibration interval (4 or 6 years). Pay attention to the date of the factory seal - perhaps the device has been in the store for a long time and half of this period has already passed.
The presence of a built-in check valve is optional, it is better to put it separately. Because of the element hidden in the housing, representatives of the water utility may reject your application, because it is simply not visible.
Purchase certified water meters that are included in the relevant state register.

Reference. The dimensions of the connecting fittings for household products are 15 and 20 mm (1/2 and 3/4″). According to the residents of the apartments, the most common are flow meters from the brands Betar, Valtec, Triton and Aquatechservice.

To install a water meter, additionally prepare the following materials and fittings (per 1 water supply line):

ball valve;
filter - mesh sump;
poppet type check valve;
metal-plastic pipe with compression fittings;
FUM tape, linen or thread for packing joints.

Advice. Choose high-quality cranes, do not chase cheapness. A broken or cracked faucet on the water supply will give you a lot of trouble. If you need to connect with steel pipes, buy special crimp adapters, for example, from the Gebo brand. More information about such connections is described in the video:

Installation instructions

When it comes to installing a water meter in an apartment, the first thing to do is to take care of blocking the risers. There are 2 ways: contact a house plumber or turn off the water supply yourself by going down to the basement. If the bathroom has already been completed correct connection and there is a main valve in working order, then it will not be necessary to shut off the water supply.

Advice. Warn your neighbors in advance about the time and approximate duration of the work, and hang a warning sign in the basement so that no one opens the tap and floods your apartment.

To assemble a small circuit with a counter, it is desirable to allocate space for horizontal mounting site. When this is not possible, install the unit vertically, the main thing is that the device does not hang “upside down”.

Vertical installation of metering devices

The assembly technology is as follows:

Disconnect the domestic water pipe from the main faucet. The steel pipeline will have to be cut with a grinder.
As a rule, old valves in apartments jam or leak, so they must be replaced. Unscrew the valve from the pipeline with a gas wrench and put a new locking element in its place.
Pack the threaded part of the valve and screw on the strainer. If both elements have internal thread, you will need a transition piece - a futorka.
Install the meter, respecting the direction of flow. To do this, the fitting with the union nut (American), which comes with the kit, must be connected to the sump (do not forget to put on the nut!), Then screw the device itself.
Last detail - check valve. Connect it to the second output of the flow meter, also maintaining the direction of the water, it is indicated by an arrow on the valve.
Cut the pipe to size and connect it to the valve with a compression fitting.

Typical Wiring Diagram

Note. Installation of a water meter in a private house is carried out in the same manner, only in some cases the water meter unit is placed in a dry well.

After assembly, smoothly open the main faucet and supply water, observing the tightness of the connections. Tighten or repack if necessary. How installation work performs a master plumber, look at the video:

Legalization and sealing

For execution last stage you need to call the controller or the caretaker of your housing office. He will inspect the water meter assembly and put a seal on the meter by threading a special thread through the eyelets in the body and the upper union nut (and sometimes the lower one). Acceptance will go smoothly if the device is installed without violating the rules and has a factory passport with a mark on the date of the next verification.

Reference. It is important that access to the water meter is provided, the assembly corresponds to the scheme, and there are no tie-ins in the pipeline in front of the flow meter.

After sealing, the current meter readings are entered into the documentation and a new contract is drawn up (or the old one is corrected). Next is the operation, during which you check the readings of the water meter and periodically clean the strainer.

Conclusion

Central water supply is not gas pipelines, where only licensed firms and trained specialists are allowed. Nevertheless, pipelines and fittings operate under pressure of 2-6 atm and therefore must be installed with high quality and without leakage. Otherwise, the installation of water meters is not difficult and does not require much experience in the field of plumbing.

You can install a water meter:

on one's own. After installation, be sure to contact the management company so that its employees seal the meters and draw up a commissioning certificate. The management company has the right to refuse to register meters for you if it considers that technical requirements when they were installed were violated;
with the involvement of a specialized organization. You can choose it yourself or ask your management company for a recommendation. After installation, the organization must issue you a commissioning certificate and other documents for the meters. Please contact the management company with these documents to draw up a contract for settlements on meters.

You can view the contacts of your management company on the portal.

After the meters are put into operation, starting from the 1st day of the next month, you will be able to pay for water supply and sanitation according to the readings of the meters.

After a certain time, it will be necessary to check the water meters to make sure that they work correctly.

2. How to install electricity meters?

After the issuance of the law of July 1, 2013, each consumer is obliged to install a device that takes into account water consumption in his premises. The sooner the owner of the apartment mounts a meter in it, the less he will have to overpay for water, the cheaper the installation procedure will cost him. And the overpayment is significant: the minimum average consumption set by the water utility is 5.5 cubic meters per person per month, and a maximum of three cubic meters are actually used. Yes, and the installation of a meter by a licensed contractor is becoming more expensive before our eyes, because the demand for such work is growing. At present, the "issue price" ranges from 5-6 to 9 thousand rubles for two meters (hot and cold water) and their installation. After installing the meter, the costs pay off within one to one and a half years. In some cases, costs can be reduced by self-assembly water meters, if allowed by the water supply organization.

Obtain permission from the housing organization for self-installation; then take the written specifications and a list of models that can be purchased. If permission cannot be obtained, you can look up information about licensed contractors and choose one of them.
Buy water meters and all the necessary equipment.
Install them independently or with the help of hired specialists in the water supply system of an apartment or house.
Call a representative of the water utility for their sealing.
Obtain an act of commissioning, a technical passport and a certificate of verification of devices.
Conclude with the housing organization an act on payment by meters.

Sectional water meter

Purchase of water meters

The number of meters depends on the number of risers in the room. In houses where heating is carried out using columns, one appliance is enough on the pipe that supplies water to the house. Most often, at least two devices are needed for a city apartment: one for a riser with cold water and one for hot. And in an apartment with a Soviet layout: two risers to the bathroom; two - to the kitchen, one - to the toilet - you will need 5 appliances. These expenses will not pay off even in a few years! Therefore, with the installation of a meter in such an apartment, you can wait.
Water meters for cold water are distinguished by a blue stripe and operate in the temperature range from +5 to +40 degrees. Devices for hot water - marked in red and can withstand temperatures up to 130 degrees.
The purchased devices, together with the technical passport, must be checked in the instrumentation of the water utility or the city to make sure that the meter is winding correctly. This procedure is free, it is marked with a CIP seal and a stamp in the passport. The serial number of the product must match the data in the passport, otherwise there will be problems with the acceptance of work by the water supplier.
For domestic use you can choose inexpensive mechanical water meters of single-jet and multi-jet types. It is better to choose meters made according to the “dry scheme”, they are a little more expensive, but they will not allow the device to be contaminated with water impurities. The most popular are the models ETKETW-15.2 (Modularis-safe mag), "Teplouchet-1", Siemens devices (more expensive). There are models with a reed insert for automatic transmission of readings, which is not yet relevant and only increases costs.
Additional parts needed for installation: shut-off valve; coupling-adapter; cleaning filter; check valve; rubber gaskets; union nuts - "American", fittings, sealant and plumbing paste.

Scheme of installation of water meters

Choice of location. General principle: tapping is carried out no further than 20 cm from the pipe entry into the room (from the floor or wall). This rule excludes water diversion to the side without taking it into account. In a city apartment with one riser, the meter crashes into the toilet next to the toilet. You can install it in the bathroom if the pipes go to the toilet along the floor.

In private houses, water meters are placed at the point where the pipes enter the room. water well, if any, must be provided with a sealed cap.

Mounting elements of the system

Order of arrangement of components

Before starting work, lay out all the parts in the order required for assembly:

Stopcock it must hold the pressure of water, block its supply to the room. Therefore, it is better to have a brass version; for modern pipes, you can take a plastic constipation.

check valve. It is bought independently, water suppliers pay Special attention for its presence and do not accept water meters without it. This valve protects the measuring system from rewinding readings. In the absence of liquid in the water supply, if the taps are opened, air is sucked in and presses on the system from the back.

Assembly of parts
- It is necessary to wind the filter onto the shut-off valve, counting the turns and noting when the position of the filter is lid down. After determining the required number of turns, the filter is unscrewed back, a linen tow cord is wound around the thread so as to close the groove. The wound tow is covered with sanitary paste and the filter is screwed on the tap. If you choose as a heater silicone sealant, then, having dried, it can lose plasticity and burst from the inside,
- An “American” with a sealant is screwed onto the filter, after which a counter is built in. On this side, the connection is sealed with a rubber ring, and it is better not to use tow and other improvised seals for a hot water appliance - you need to choose a harder and more inflexible paronite gasket, sized to fit.
- The meter on the other side is connected to the check valve using a second pipe and a nut with a gasket. Pay attention: with the “American” filter, they are connected to the filter from the point of the arrow, and with the check valve - from the side of the end of the arrow.

sidebar assembled structure into the pipe

Metal pipes are especially difficult; they need a metal saw and a threading device. To facilitate the work, you can replace a fragment of the pipe on which the meter is mounted with metal-plastic or polypropylene.

Connection to risers

Block the flow of water to the riser.
Measure the resulting structure from the tap to the check valve. Set aside this segment on the main pipe, starting from the old tap into the room along the flow.
Cut off this section of the pipe, substituting a container under the cut in order to glass the liquid. Unscrew the old tap, and if this fails, cut it out and make a new thread. When replacing a metal fragment with propylene, the cuts at the transition points from metal to plastic are connected by fittings.
The design is screwed to the supply pipe, then the check valve is unscrewed from the water meter and inserted into the thread of the receiving pipe. The "American" valve is again connected to the water meter. Installation completed.
It remains to check the mounted system. This must be done carefully, gradually opening the tap so as not to damage the meter with strong water pressure. An inspection is carried out: is there a leak, and is the device working. It is necessary to pay attention to the arrows again: on all the details they should look in the direction opposite to the stopcock.
If everything is in order, you can invite a specialist to seal the counter.

Putting the meter into operation

The summoned representative of the water utility must appear within three days. It checks if the counter is set correctly; its certification and instrumentation stamp in technical passport. Then he put a seal on the entire water meter assembly. An act is drawn up on the acceptance of the system into operation and enters the primary indications into it.

The technical documentation of water measuring instruments consists of the following documents:

Contract for the installation of the device.
Technical passport (it is better to make a photocopy for the water utility and for the landlord).
Certificate of conformity.
Commissioning certificate (drawn up on site at the time of sealing)
Verification certificate (by the time of sealing, two verifications were noted in the data sheet: one factory and one KIP)
Contract for payment of water supply by meter (drawn up in a housing organization).

After all the formalities, the owner of the meter has the right to pay for the actual consumption water resource and recoup the cost of installing water meters

Rules for the operation of water meters

Do not remove the seal for repair and cleaning of the device. It is necessary to call a specialist who is obliged to do this for free.
If the seal is broken, immediately inform the water supply office and call a specialist: you will have to pay for the secondary sealing. But it is better to choose such expenses than a fine or payment for all the time since the last check.
The cold water meter is checked once every four years, and hot - once every six years. These scheduled inspections are mandatory, at this time the payment is based on the average minimum consumption.

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 give 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. It's about about situations when 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 for 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 figures here, since the entry points in different buildings may differ, moreover, 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! Semi-open position for ball valve- 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. Unwind everything, take a seal (you can use the usual linen tow) and wrap it around the stopcock filter.

In addition to tow, as a sealant threads made of polyamide "Tangit Unilok", which additionally have 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 required area, after substituting a 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- these are bureaucratic ups and downs, obtaining and approving various papers, filing applications, and so on. 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.

After much debate and hard thinking, you still decide to install water meters in Moscow. Have you ever had seditious thoughts that in today's conditions, when water networks do not work very well, installing meters is not the best thing to do?

You were told that when the water pipes are worn out, it is difficult for you to install the IPU purely physically. This operation will become costly and will not benefit your family budget. Or your water heats up for a long time and you have to spill it until it reaches the desired temperature. At this time, the expense will begin to wind up and you will have to pay.

However, practice shows that such fabrications do not have the slightest foundation. Whoever says this has never read the real rules. Their conclusions are based on speculation. You must make a decision after carefully analyzing the situation.

Before adopting a mandatory law, the Russian government used calculations that were carried out by specialists. Those, in turn, relied on world experience, where they have been using units for a very long time to save resources and money.

We also gained Russian experience in installing devices. Only then did he see the light the federal law, who spoke with his points about the installation of meters on a mandatory basis. Prime Minister Dmitry Medvedev independently convinced the population of the need for this service.

The legal act forced the installation of appliances in apartments. Otherwise, imposing financial sanctions were imposed. Naturally, no one was going to go to your apartment with a rifle. Just for the lack of such measuring elements, the legal mechanism was turned on.

According to the law, it followed that the absence of water meters leads to the fact that an increasing coefficient for water consumption begins to apply to your apartment. Its progressive scale forced tenants to install, but not with my own hands, water appliances. The rules began to work.

There was a question how to install a water meter. There is no difficulty in this. There are many companies that offer this service. You just have to choose the right one, but you must not make a mistake in this.

Which company to choose to install water meters in Moscow?

The company must follow the rules. It employs craftsmen who not only inspire confidence, but also install high-quality IPU. You will be able to determine the quality of work on your own, because your documents will be accepted by the settlement authorities by registering the counters.

The City Center for Accounting and Saving Resources has a special certificate that issues federal Service to their agents for accreditation of activities for the installation and verification of water meters in Moscow. Installing is only a part of owning and operating said equipment. It needs to be serviced.

And this is a verification procedure, which is carried out after a certain period of operation of the installed device. The GCUiER company conducts according to two schemes:

You negotiate with the operator and place an order for checking water meters. A master comes to your house and removes the meter, placing a temporary adapter in its place. The mechanism is verified in the metrological service. After this process, the master carries out the installation, placing the device back.
The modern and most common way is to check water meters at home. It passes without removing the unit using special equipment. After that, you are given documents on such work, which you refer to the settlement organization.

For hot, verification is carried out once every four years. Cold ones were set a deadline two years later due to exposure to less than high temperatures. After installation, you yourself will have time to decide on the organization for their verification. That is, Which water meter installation company is best, she will serve them.

What documents are issued when installing water meters?

the first, of course, is the passport of the water unit itself. According to it, it is possible to establish both the date of issue and the calibration intervals of the device. Without it, it is impossible to carry out any maintenance work on the meter. There are also certificates;
you will be given an act of work performed, which will indicate which, in fact, took place in your apartment;
you will have the act of entering measuring device into operation. The number of the seal is also indicated. It will be sent to you in triplicate. The first will remain with you, the second - with the master who installed the water meter, and you will give the third to the Criminal Code;
you will have paper that you do not need to transfer anywhere. It just confirms your rights if you install a malfunction. It is called a contract for the installation of this equipment.

Some additional agreements may be issued that emphasize your legal grounds for owning and operating instrumentation to a greater extent, and it is not made by yourself.
