How to install the meter on water

Constantly growing water tariffs and water consumption norms unreasonably inflated by the water channel encourage consumers to install meters on water. Having decided to install a counter for cold water supply, contact the water canal, there you will be given a technical requirement for a water meter. It is advisable to purchase the meter of the current year of production, then after the purchase, verification of the instrumentation is optional. The vodokanal put a mark in the technical passport of the water meter, and the date of sealing is assigned. It is very important to install the meter carefully when it comes to seals. It is not forbidden to install the meter yourself. Video of the process of installing the counter on water at the end of the article.

Main characteristics of water meters

Acquiring water meters is better in licensed stores,passport and 3-year warranty. There are three types of household appliances for water accounting:

• cold water meter;
• hot water meter;
• water meter for installation in the well.

The most popular and inexpensive counters are rotary, there are fewer turbines, and new-fashioned ultrasonic counters are on sale extremely rarely.

Standard internal wiring in homes and apartments is assembled from ½ and ¾ inch pipes or 16 and 20 mm. Household counters differ only in diameter of mounting releases. It will not be a violation to cut and install an ½ inch counter into the piping system with ¾-inch pipes or vice versa using adapters. It is optimal to purchase a meter with outputs corresponding to the diameter of the pipes of the water supply system. The design of any meter provides for the possibility of mounting, both with horizontal and vertical wiring.

Tools and equipment for the water meter

The following tools are required for mounting the water meter:

• adjustable pipe wrench No. 1 or No. 2;
• car keys number 14, 17, 19 and 30;
• rubber or paronit gaskets ¾ or ½ inches;
• linen tow( rewind);
• water-resistant silicone.

To assemble the water meter assembly, you will need to purchase the following accessories:

• shut-off valve;
• coarse filter;
• check valve;
• water meter.

1. The shut-off valve or ball valve is purchased from brass and from a reliable manufacturer. In the event of a leak or failure, this tap stops the flow of water into the room.
2. The cleaning filter prevents clogging of instruments with rust and dirt residues arising in the supplied water after repairing the networks. A purification filter made of brass or bronze is purchased. It is better to buy with reinforced walls, the thickness marking is applied to the body of the product. Filters are available with a direct or oblique sedimentation tank. The inspection cover must have a tab for the seal.
3. The non-return valve is installed in case of sudden water shutdown. In this case, a reverse thrust may occur, and the air flow will cause the counter to work in the opposite direction. The non-return valve prevents the reverse operation of the water meter.
4. Good counters are of domestic production. Somewhat better Czech or Polish hydrometers. The most popular household counters of German production. When buying, check the warranty card and the quality certificate. When deciding which water meter to install, consider that the line between domestic meters and imported ones is rather thin. Domestic meters are issued under foreign licenses for imported equipment. In the event of a breakdown, it is easier to file claims with the factory to the manufacturer in your country.

Preparing for installation of a water meter

The installation site is selected after the riser on the house casing before the sanitary equipment.

Important: there must be no collapsible joints or leaks on the gap between the riser and the water meter. The location should be convenient for setting and reading the meter.

1. The parts for the water meter block are laid out in one line: a shut-off valve, a cleaning filter, a water meter, a check valve. On the body of the parts there is an arrow indicating the direction of the water head. All of them should point in the same direction from the stopcock to the indoor wiring.
2. In case if you made a mistake with the threaded connection when the parts were purchased or the parts with the correct thread were not available, the position can be corrected using the nipple n / p - n / p( male thread) or the coupler in / p - in /thread).
3. The parts are collected dry and without pakli and gaskets. Dry assembly is necessary to count the turns and install the protruding parts in the desired position. Full turns in standard details are not more than five. Sometimes, in order to install the cleaning filter settler in the bottom direction of the clarifier or for a convenient position, the valve's grubboxes need to make 4 or 4.5 turns. This is achieved with the help of linen winding.
4. A strand of linen fibers separates from the bundle of pakli. It is combed by fingers - leveling and removing the rubbish, and then it is twisted into a thin cord about 1 mm thick. From the edge of the threaded connection, the cord is tightly wound clockwise in the direction of the base. A small compaction is made at the very base. The winding is smeared with a thin layer of waterproof silicone, and the connection is tightened with keys.
5. It is important not to screw or thread the screw connection. In the first case, the body of the part can give a microcrack, and in the second a leakage occurs. After installing the water canal inspector, seals, alterations or repairs are very problematic.
6. The water meter kit includes nozzles with union nuts( American) and gaskets. When installing the meter for hot water, it is advisable to replace the rubber gaskets with paronit ones. For the cold water meter you can leave rubber.
7. The design of the water meter assembly assembly for horizontal installation is as follows:

• shut-off valve - the valve is pointing upwards;
• cleaning filter - settler up( with vertical mounting - down);The dial of the filter looks up;
• impeller - down.

Insertion of a water meter into the

1. pipeline The assembled block is measured by a tape measure at the outermost discharges. In the apartments for installing the meter, the riser is blocked, in private buildings there is a main water pipe. To install two counters simultaneously on hot and cold water, both risers are overlapped. At the place of installation, a cut-in is made according to the size of the water meter collected. In that case, if the pipes are metal, the thread is cut. Plastic pipes are easily connected by fittings.
2. For tapping of metal pipes, a tensioner of the appropriate diameter is used. The edges of the pipes are treated with a file - the chamfer is removed. The treated part is smeared with a solid oil or oil. Lerca pushes on the edge of the pipe and clamps it. With special handles or the adjustable wrench, the movable part of the laser is turned to the required number of threaded threads.
3. For private houses, the installation of a water meter is usually designed in the nearest well to the house. For this purpose, a meter intended for operation in the well is purchased. The way of installing such a counter does not differ from the installation of a water meter in the room.
4. After installation, the operability and absence of leaks in the system is checked. The shut-off valve opens smoothly to gradually fill the system. The water pressure is brought to maximum, and the connections are checked for leaks. Opening the cranes of internal sanitary ware, the work of the meter is checked.
5. If problems are not found, the representative of the water canal is invited for sealing. After sealing and recording of current indications in the settlement book, the device is considered to be put into operation.
