How to install water meters

Steadily rising water tariffs and water canal unreasonably high standards of water consumption are pushing consumers to install water meters. In deciding to install the counter on the cold water, contact the water utility, where you will be given a technical requirement for water meters. It is advisable to purchase a counter current of the release, then the post-acquisition instrumentation calibration is not necessary. Vodokanal put a note in the data sheet of the water meter, and appointed the date of sealing. It is important when installing the counter cares for fillings. Install the counter alone is not prohibited.

Acquire better water meters in licensed stores, attached to the device data sheet and a guarantee of 3 years. There are three types of appliances for water meters:
Counters of cold water;
hot water meters;
water meter to be installed in the well.

The most popular and inexpensive meters - Rotary, rarer turbine, and ultrasonic meters newfangled found on sale very seldom.

Standard internal wiring in homes and apartments assembled from pipes ½ and ¾ inch, or 16 and 20 mm. Household counts differ only in the diameter of the mounting issues. There will be no violation of punch and install using adapters counter ½ inch in the pipeline system with pipes ¾ inch or vice versa. Optimal purchase counter with releases corresponding to the diameter of the water pipes. The design provides the ability to counter any installation, both in horizontal and in vertical layout.
Tools and equipment for the water meter

For the installation of a water meter will need the following tools:
adjustable pipe wrench №1 or №2;
spanner number 14, 17, 19 and 30;
Rubber pads or paronitovye ¾ or ½ inch;
flax tow (preroll);
water-resistant silicone.

To assemble the unit will need to purchase a water meter components:
off valve;
strainer;
a check valve;
Meters for water.

Isolating shut-off valve or ball valve made of brass and is purchased from a reliable manufacturer. In the event of a leak or accident that the crane stops the flow of water into the room.
The cleaning filter prevents clogging of devices remains rust and dirt occurring in the feed water after repair networks. Acquired purifying filter made of brass or bronze. It is better to buy with reinforced walls, the thickness of the marking applied to the enclosure. Filters are available with direct or oblique sump. Auditing cover must have an ear for the seals.
The check valve is installed in case of a sudden shutdown of water. In this case, it may be the reverse thrust, and the air flow will cause the counter to work in the opposite direction. The check valve prevents reverse operation of the water meter.
Satisfactory meters are produced domestically. Several of the best Czech and Polish water meters. The most popular domestic counters of German manufacture. When buying, check the warranty card and certificate of quality. When deciding what to install water meters, note that the line between domestic and imported counters rather thin. Domestic meters are manufactured under foreign licenses on imported equipment. In case of failure it is easier to claim by the manufacturer in the country.
Preparing for installation of the water meter

Location selected for installation on the riser after intrahouse wiring before plumbing.

Important: the gap between the riser and the water meter should not be gasketed joints or strains. The location must be convenient for installation and meter reading.

Parts for water measuring unit are arranged in a single line: shut-off valve, cleaning filter, the counter of water, non-return valve. On the body parts has an arrow - pointer to the direction of water pressure. They should all point in the same direction from the stopcock the indoor layout.
In case you have when buying parts wrong with threaded connection or did not have in stock the items with the correct thread, the situation is fixable by means of the pin n / p - n / p (male thread) or the clutch / p - a / p (female thread ).
Details going to dry without hemp and gaskets. Dry assembly need for counting revolutions and install parts protruding elements in position. Full details of the coils in the standard of not more than five. Sometimes, to be installed in the lower direction of the settler or filter cleaning for easy granbuksy valve position required to make 4 or 4.5 turns. It is achieved by means of rolling the linen.
Because the beam is separated strand hemp linen fibers. Combed fingers - leveling and removing litter and then twisted into a thin tow rope about 1 mm thick. From the edge of the threaded joint twine tightly wound in the side of the base clockwise. At the very bottom is a small seal. Preroll smeared a thin layer of water resistant silicone compound and delayed key.
It is important not transmitting or nedozhat threaded connection. In the first case, the body parts may give microcracks formed in the second leakage. After installing the water utility inspector seals, alteration or repair is very problematic.
The kit includes a water meter connections with cap nuts (American) and gaskets. When installing the counter for hot water, it is desirable to replace the rubber gaskets on paronitovye. To counter the cold water can leave the rubber.
The construction of the water meter block assembly for the horizontal installation is as follows:
shut-off valve - the valve pointing upwards;
Cleaning Filter - sump up (when mounted vertically - down);
face filter - looking up;
impeller - down.

Box water meter in the pipeline
The assembled unit is measured with a tape measure on the extreme issues. The apartments for meter installation overlaps the riser, in private buildings - water main. To set the two counters at the same time hot and cold water are overlapped, both the riser. The installation site is inset on the size of the collected water meter. In the case of metal pipes, threaded. Plastic pipe fittings are easy to connect.
For tapping on pipes of metal applied tension chaser corresponding diameter. The edges of the pipe with a file processed - chamfered. Processed parts lubricated with grease or oil. Ljerka is placed on the edge of the tube and fixed terminals. A special pen or a wrench moving part chaser rotated to the desired number of screw threads.
For private homes Installation of a water meter is usually designed in the well near the house. For this acquired intended for use in a well counter. How to install this meter does not differ from the installation of water meters in the room.
After installation, check the efficiency and the absence of leaks in the system. Shut-off valve is opened slowly to gradually fill the system. Water pressure is brought to the maximum, and connections are checked for leaks. Open the valve internal plumbing, checked the work counter.
If problems are found, it invites representatives of the water utility for sealing. After sealing and record the current reading in the passbook, the device is considered to be put into operation.
