MOUNTING THE WATER COUNTER WITH YOUR HANDS - WHAT YOU NEED TO KNOW
WHEN THE WATER SUPPLY EXPERTS SET UP THEM, THE EXISTING WATER SUPPLY SYSTEM IS ALREADY CHECKED IN ALREADY. Such work is not easy to do if you have specific skills for working with a sanitary fixture. IT WILL ALLOW THE SAVINGS ON THE CHALLENGE OF SPECIALISTS.
In order to avoid problems in the future, it is better to agree on the type and brand with the operating organization before buying the meters. The counter should be sold with a passport and have an individual number. The main parameters are usually reflected on the instrument panel.
Do not buy the device in advance or "not very fresh." Remember: the deadline for the next re-attestation will not be calculated from the moment the meter is taken into use, but from the date of its issue and technical control at the manufacturer.
Meters are available for cold, hot water and universal. This information must be reflected in the passport indicating the range of operating temperatures. Color coding of the case (usually blue or red) increases the usability of the device. An additional plus is multi-colored plastic pads in the configuration of universal meters. Another important parameter to keep in mind is the diameter of the conditional passage, and more simply, what is the diameter of the pipes on which this device will be installed. There are a number of parameters: accuracy class, maximum allowable pressure in the system, maximum water flow. It must be remembered that excessive requirements for these parameters will lead to an unreasonably high price of the device.
Dimensions (110 or 130 mm) of the device - the standard value for the water supply in apartments.

GENERAL RULES OF PREPARATION FOR INSTALLING THE COUNTER
Before self-assembly, you must familiarize yourself with the management company with the technical conditions for installing metering devices - they may vary in different regions. Water meters should be located as close as possible to the entrance of the water pipe to the apartment (to the riser). Between the water meter and the inlet there should be no technical possibility for unauthorized water withdrawal.
At the entrance to the apartment, a shut-off valve and a coarse mechanical filter must be installed (mud filter, strainer for coarse water purification from large inclusions).
According to the technical installation conditions, a check valve must be installed after the water meter. This allows the meter mechanism to always be in a "wet" state. The water meter should always contain water: it provides a kind of "lubrication" mechanism. And also it is necessary to exclude the possibility of reverse exhaustion of the instrument readings by compressed air. A non-return valve can be structurally located in the connection socket of the water meter. When selecting meters, this feature should be reflected in the instrument's passport.
The type of shut-off valve (tap) does not matter. Ball valves should be used in two positions - “open” and “closed”. An intermediate position leads to rapid wear of the mechanism.
WATER PRESSURE REGULATOR BUILT IN WATER SYSTEM WATER PRESSURE REGULATOR PREVENTS MANY DISPOSALS: PROTECTS THE NETWORK FROM HYDRODUARDS, EXCLUDES THE OUTPUT FROM THE EQUIPMENT SYSTEM AT PRESSURE DIFFERENCES, HELPS THE WATER FLOW, REDUCES THE WORK PRESSURE WITH REDUCED PRESSURE AND PRODUCED NOISE.
For the coarse coarse filter, the nut of the oblique elbow for cleaning should have a special hole in which a wire is passed when sealing. This is necessary to prevent unauthorized water withdrawal.
Connecting fittings with nakidnymi nuts - "American", usually included in the delivery of the meter. A non-return valve can be placed in the left fitting.
TRIAL START
After the system is assembled, we carry out a test run. Slightly opening the faucet, fill the system with water, open the water analysis points - let the air out of the system, close the analysis points and check for leaks in the connections. The easiest way is to place the expanded napkins or sheets of toilet paper under the joints.
AFTER INSTALLING COUNTERS
To register water meters, you must apply to the management company. The wizard will check the correctness of the installation, the availability of documents and install seals. The signed act of commissioning a meter imposes on you some responsibilities. It is necessary to submit a monthly meter reading to the operating organization. The timing of their transfer is harsh, but in the absence of evidence, problems will not arise within three months. During this period, bills will be issued at the average monthly expense. Then the calculation will go according to the standard.
It is necessary to let employees of the management company to check the meter (not more often than once in six months). Denial of access may lead to a loss of the opportunity to pay for their water consumption by the meter, and the management company will have the right to charge you with water consumption according to the standard.
