Installation of cold and hot water meter in each apartment helps not only to control the consumption of this important resource, but also significantly reduce the cost of paying utilities. If in the new buildings, the counters are set "by default", then in the houses of the old construction, the metering devices will have to be installed independently. One of the most important incentives to mount such a device is a law that obliges to make all consumers of cold and hot water. This norm has been operating since July 2013, so it is impossible to pull with this issue.

The installation of meters on hot or cold water does not take much time, and if there is a set of a plumbing tool and certain locksmith skills, such an operation can be carried out independently for a rather short period of time. In addition, it will be able to significantly help the family budget, because for a small amount of mechanic work, there are quite considerable money. The only thing that must be considered when carrying out this operation is accuracy. The water pressure in the apartment building system can reach 3-4 atmospheres, which is why an inaccurately assembled system can cause large problems. On how to choose and perform the installation of water meters in the apartment - hereinafter.
How to choose the water meters
Water meter is inherently not a complex device. With all the variety of manufacturers of these devices, the principle of their work is unchanged. There are two varieties of water metering devices:
- Mechanical turbines. The principle of their work is quite simple. Thanks to the rotation of the flow of water flow through the turbine, its impeller rotates. This rotation is transmitted to the counting mechanism, which takes into account water consumption. Such flowmeters have a large service resource, easy to execute and install and stand relatively inexpensively.
- Electronic. Such counters are quite expensive and inferior in reliability to their mechanical fellows. Therefore, their popularity is low enough.
Choosing meters for an apartment with central hot water supply. It is necessary to understand that hot and cold water flowmeters have different structural features and, accordingly, the cost. The hot water meter can be installed on the feed cold, but on the contrary - no. It just won't pass the seal.
Choosing a counter should not pay attention to sellers who offer "expensive, but qualitatively." All water metering devices are standardized and the manufacturer must receive a certificate of conformity before the product goes on sale. Such a certificate means that the device has passed the test and is ready for operation. Therefore, it should not be chased for something "supernatural".
By purchasing the accounting device, you need to pay attention to its completeness. It must be equipped with a check valve, two cape nuts, sealing gaskets and a mesh filter. Some are not clean on the hand of entrepreneurs specifically pull all these details out of the box to sell them separately. Be sure to complete the list in the passport.
The passport of the product is the main document that is necessary when the instrument is commissioned. It must be printed by a typographic way to indicate the device number, the date of manufacture, testing, the passport must stand the discs and the manufacturer's printing. It also indicates the frequency of calibration of the device. Rooms in the passport and on the device must coincide - it is very important. If there are problems with the passport, you will have to pay extra for calibration before sealing.
Selection of shut-off reinforcement for water meter
When installing the meter, the system needs to install a lock fittings that will provide the ability to maintain it. Some manufacturers are equipped with their accounting devices for locking reinforcement. It must necessarily have an eye on its hull through which the sealing wire is done. It is done so that the user does not have the opportunity to disconnect the filter from the crane and use water. In some cases, when using plastic pipes, you can not seal the crane itself, however, these questions need to be solved with controllers that will carry out sealing. Cranes are better to choose metal plastic or brass. They have a fairly large safety margin. It is better not to use the silicon cranes. They are often susceptible to the destruction that occur due to corrosion of the crystal lattice. In the case of cracking, the crane case will be quite problematic to block water. This can be done only through the cut-off valve of the entire riser, which is in the basement. While it will be necessary for this time, a real flood can happen in the apartment. Especially if the pressure is high. Therefore, it is better not to save on the shut-off fittings.
Rules for mounting water meter. Choosing a place of installation
When installing the meter on cold and hot water, it is necessary to choose the right place for them.
- Availability. Counters must be located so that access to them is simple. During operation, it will be necessary to remove them for checking, clean the mesh filter, etc. If you install it in a hard-to-reach place, all the above operations will be problematic.
- Close distance to the point of input. This requirement of waterochannels. The installation location of the meter must minimize the possibility of cutting into the pipe to the counter. At the same time, the entire pipe from entering to the counter should be visually visual.
- Indoor temperature. According to the technical conditions, the working temperature of the environment for water metering devices should be at least + 5 ° C. For their installation in the apartments there are no problems, in the conditions of the private house, the installation site should be a capital well.
Typically, the counters are installed in the bathrooms, not far from the input point. As a rule, such a place is a toilet. You can hide the counter to a special niche, which will be opened if necessary.
Installation of water meters in the apartment
The process of installing the metering device is rather simple. To do this, you will need:
- Counter with a set of filter, crane, and check valve.
- Wrench Water Room No. 1.
- The wrench wrench sliding (if there is a set of standard horn keys, they can also be used successfully).
- Winding. There are several options: palabo or rubber tape. You can use with an equal degree of success and the other, this is someone as convenient.
The order of installation of water meters is as follows:
- First of all, it is necessary to overlap the flow of water. At the same time, it is necessary to notify the neighbors about this. If someone at this time will work the washing machine machine, there will be a lot of problems.
- After that, the old crane is dismantled. Carefully using a plumbing key supported pipe, and a wrench removed the crane. If it is not unscrewed, you can use WD-40 lubrication. When the crane is unscrewed, it is necessary to inspect the thread status on the pipe. In the event of an unsatisfactory state, it must be cleaned or re-pass the silence of the corresponding diameter. The thread is condensed with winding. If a pact is used, it can be lubricated by any thick lubricant, for example, solidol. The crane on the thread is screwed with an average effort. It is not necessary to overdo it, since you can just thread the thread.
- Next is set by a mesh filter. It is necessary to be attentive to not put it on the contrary. It has an arrow on its case, which indicates the direction of water flow. This is how it is necessary and installed. Hound the filter on the tap thread.
- The next step is installed with a clutch with a cape nut. It is screwed into the filter thread with an external thread. It is these threads that are fixed. The nut can always be promoting and removing the meter for calibration.
- From the reverse side of the pipe is set by the check valve. It is needed in order not to "unscrew" the counter back. The valve passes water only in one direction. All connections are compacted by winding. The second clutch with a cape nut is screwed to the internal thread valve.
- Next, between two cape nuts, it is necessary to install the cold water meter. It is also important not to confuse the parties so that it does not spin in the opposite direction. For this, the appropriate marks are installed on the instrument housing. Set the counter simply. Gaskets are installed inside the cape nut. They can be made of paronite, rubber or silicone. The first option is better for hot water, the second is for the cold. Rubber gaskets are now rarely. After installing the nut pads, it is easy to clamp, supporting the case of the meter key.
- Next when the system is collected, you can connect the riser to water supply. Just in case it is necessary to lay a rag or substitute a bath with water. In this case, the shut-off crane should be closed.
- After the water is included, the first thing it is necessary to check the presence of leaks between the crane and the pipe. If it is necessary to gently press the crane. If it is not, the crane opens and check all other connections. Checking the presence of leaks is carried out using toilet paper. The fact is that even weak water drops are visible. It is just necessary to spend a small piece in places of connections and look at the result. In case of leak detection, the connection is pressed. If there is anyway anyway (this is the most unpleasant moment) you have to overlap the tap and repack the connection.
- After the meter is installed, you need to call the service with subscribers and call a specialist. He will come, check the documents and will make sex. The results of the first indication of the meter and will become a point of reference to the water consumed.
