Constantly growing tariffs for water and unreasonably overestimated water consumption regulations pushing consumers to install meters to water. After making the decision to establish a meter on the supply of cold water, contact Vodokanal, there you will be given a technical requirement for the water meter. It is advisable to purchase the meter of the current year of release, then after the acquisition, the calibration is optional. In the Vodokanal there is a mark in the water passport of the water meter, and the date of seal is assigned. It is very important when installing the meter carefully refers to seals. Install the counter is not prohibited. Video process of installation of the water meter at the end of the article.

The main characteristics of water meters
Acquire water meters better in licensed stores, the technical passport and warranty for 3 years are attached to the instrument. There are three types of household appliances for water metering:
- cold Water Counter;
- hot water meter;
- water meter for installation in the well.
The most popular and inexpensive meters are rotary, the turbine are less common, and new-fashioned ultrasound counters are on sale extremely rarely.
The standard internal layout in homes and apartments is mounted from the pipe ½ and ¾ in. Or 16 and 20 mm. Household counters differ only in the diameter of the mounting issues. It will not be disrupted to embed and install with the adapter counter ½ inches into the pipeline system with pipes ¾ inch or vice versa. Optimally acquired a meter with issues corresponding to the diameter of the pipes of the water supply. The design of any meter provides for the possibility of mounting, both with horizontal and vertical wiring.
Tools and equipment for water meter
To mount the water meter, the following tools will be required:
- recovering tube key number 1 or number 2;
- horn keys number 14, 17, 19 and 30;
- rubber or paronite gaskets ¾ or ½ inches;
- linen panel (winding);
- waterproof silicone.
To assemble the water meter node, you will need to purchase components:
- cutting valve;
- coarse filter;
- check valve;
- counter for water.
- A cutting valve or a ball valve is purchased from brass and from a reliable manufacturer. In the case of a leak or accident, this crane ceases the flow of water into the room.
- The cleansing filter prevents the instruments to be clogged with rust and dirt residues arising from the water after repairing networks. A cleansing filter is purchased made of brass or bronze. It is better to buy with reinforced walls, the thickness marking is applied to the body of the product. Filters are available with direct or oblique sump. The revision cover must have a seal ear.
- The check valve is installed in case of a sudden turning off the water. In this case, the reverse thrust may occur, and the air flow will make the counter work in the opposite direction. The check valve prevents the reversed work of the water meter.
- Not bad counters are domestic production. Several better Czech or Polish water meters. The most popular household counters of German production. When buying, check the warranty card and quality certificate. Solving which install the meter for water, consider that the line between domestic meters and imported is quite thin. Domestic meters are issued on foreign licenses on imported equipment. In the event of a breakdown, it is easier to make a claim to the manufacturer's facility in your country.
Preparation for the installation of a water meter
The installation site is selected after the riser on the domestic wiring in front of the plumbing equipment.
Important: On the interval between the riser and the water meter there should be no collapsible compounds or glasses. The place must be convenient to install and remove the meter readings.
- Details for the water unit are laid out in the same line: cutting the crane, cleaning filter, water meter, check valve. On the body of the parts there is an arrow - a pointer direction of the water pressure. All of them must be indicated in one direction from the valve crane to the intro-native wiring.
- In the event that when you purchase parts, it was mistaken with a threaded compound or there was no part with the necessary thread, the position is fixable using nipple N / R - H / P (external thread) or coupling in / p - / p (internal thread ).
- Details are collected dry without pacles and pads. Dry assembly is necessary for counting the turns and setting the protruding items of parts in the desired position. Full turns in standard details no more than five. Sometimes for installation in the lower direction of the cleaning filter or for convenient position, the valve cans is required to make 4 or 4.5 turns. This is achieved with a linen winding.
- Flax fiber strands are separated from the bundle of the packle. Fucks with your fingers - leveling and removing litter, and then twisted into a thin thread with a thickness of about 1 mm. From the edge of the threaded connection, the BECHEVA is tightly wound towards the base clockwise. The very reason is a small seal. The winding is lubricated with a thin layer of waterproof silicone, and the connection is delayed by keys.
- It is important not to transmit or nimble the threaded connection. In the first case, the part of the part can give a microcrack, and in the second the leakage is formed. After installing the inspector of the Vodokanal seals, alterations or repair are very problematic.
- The set of water meter includes nozzles with cape nuts (American) and gaskets. When installing the meter on hot water, it is desirable to replace rubber gaskets on paronite. For cold water meter, you can leave rubber.
- The design of the water meter unit assembly with horizontal installation has the following form:
- shut-off valve - the valve is directed up;
- cleaning filter - sump up (with vertical mounting - down);
- filter dial - looks up;
- impeller - down.
Locking water meter in pipeline
- The assembled unit is measured by a roulette in extreme releases. In apartments for installing the counter, the riser is overlap, in private buildings - a trunk water supply line. To install both two meters on hot and cold water overlap both risers. In place of installation is made in the size of the collected water meter. In the event that the pipes are metallic, thread is cut. Plastic pipes are easily connected by fittings.
- For cutting threads on metal pipes, a tension layer of the corresponding diameter is used. The edges of the pipe are processed with a file - the chamfer is removed. The processed portion is lubricated with solidol or oil. Lerka is satisfied with the edge of the pipe and fixed by clamps. Special handles or adjustable key, the movable part of the layer turns on the required amount of threaded threads.
- For private homes, installation of water meter is usually designed in the nearest well to the house. For this, the meter is purchased for operation in the well. The method of installing such a meter does not differ from the installation of the water meter indoors.
- After installation, the performance and absence of leaks in the system is checked. The shut-off valve is smoothly opened for the gradual filling of the system. The water pressure is brought to the maximum, and the connections on the leakage are checked. Opening the taps of the inner plumbing, the counter is checked.
- If the problems are not detected, the representative of the Vodokanal is invited for sealing. After sealing and recording current readings in the computational book, the device is considered to be commissioned.
