Installing the cold and hot water counter in each apartment helps not only to control the consumption of this important resource, but also to significantly reduce the costs of paying for utilities. If in new buildings, the counters are installed "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 all consumers of cold and hot water. This norm has been operating since July 2013, so it is impossible to pull with this issue.

Installations of meters on hot or cold water do not take much time, and if there is a set of locksmith tools and certain skills of locksmith work, such an operation can be carried out independently for a fairly short period of time. In addition, this will be able to significantly help the family budget, because quite considerable money is being pulled for a small amount of work of the locksmith. The only thing that must be taken into account when conducting this operation is accuracy. The water pressure in the system of an apartment building can reach 3-4 atmospheres, which is why an inaccurately assembled system can cause big problems. About how to choose the right and perform the installation of water meters in the apartment - further.
How to choose the right water meters
The water meter is inherently not a complex device. With all the variety of manufacturers of these devices, the principle of their operation is unchanged. There are two varieties of water metering devices:
- Mechanical turbine. The principle of their work is quite simple. Due to the rotation of the passage of the water flow through the turbine, its impeller rotates. This rotation is transmitted to the counting mechanism, which takes into account the water consumption. Such flow meters have a large service resource, are simple in execution and installation and are relatively inexpensive.
- Electronic. Such counters are quite expensive and are inferior in reliability to their mechanical counterparts. Therefore, their popularity is quite low.
When choosing meters for an apartment with central hot water supply, it is necessary to understand that the flow meters for hot and cold water have different structural features and, accordingly, the cost. The hot water meter can be installed on the supply cold, but on the contrary - no. He simply will not pass a sealing.
When choosing a counter, do not pay attention to sellers who offer "expensive, but efficiently." 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 check and is ready for operation. Therefore, do not chase behind something "supernatural."
When buying an accounting device, you need to pay attention to its completeness. It should be equipped with a check valve, two pitch nuts, sealing gaskets and a mesh filter. Some entrepreneurs are not clean in hand specifically pull out all these parts from the box to sell them separately. Be sure to check the completeness according to the list in the passport.
Product passport is the main document that is necessary when putting the device into operation. It must be printed in a typographic way indicating the number of the device, manufacturing, testing, the passport should be stamped by the OTC and the manufacturer's print. It also indicates the frequency of verification of the device. The numbers in the passport and on the device must match - this is very important. If there are problems with the passport, you will have to pay extra for verification before sealing.
The choice of shut -off valves for the water meter
When installing the counter, it is necessary to install shut -off valves in front of the system, which will provide the ability to serve it. Some manufacturers are component of their accounting devices with shut -off valves. It must have an ear on its body, through which the filling wire is threaded. This 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 fill the crane itself, however, these issues must be resolved with controllers who will carry out sealing. It is better to choose cranes with metal -plastic or brass. They have a fairly large margin of safety. It is better not to use silumin cranes. They are often subject to destruction that occur due to corrosion of the crystal lattice. In the case of cracking of the crane case, it will be quite problematic to block the water. This can only be done through the cutting tap of the entire riser, which is located in the basement. While the necessary time passes for this, a real flood may happen in the apartment. Especially if the pressure in the system is high. Therefore, it is better not to save on shutoff valves.
Rules for installing a water meter. Choosing the installation site
When installing a meter on cold and hot water, you must choose the right place for them.
- Accessibility. The counters should be located so that access to them is simple. During operation, it will be necessary to remove them for the check, clean the mesh filter, etc. If you install it in an inaccessible place, all of the above operations will be problematic.
- Close distance to the input point. This is a requirement of water utilities. The installation site of the counter should minimize the possibility of inserting into the pipe to the meter. At the same time, the entire pipe from entering to the meter should be visually visible.
- The temperature in the room. According to the technical conditions, the working temperature of the environment for water metering should be at least +5 ° C. There are no problems for their installation in the apartments, in the conditions of a private house there should be a capital well.
Typically, 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 in a special niche, which will open if necessary.
Installation of water meters in the apartment
The process of installing the metering device itself is quite simple. This will need:
- A counter with a set of filter, crane, and check valve.
- The key water supply No. 1.
- The wrench is sliding (if there is a set of standard claw keys, they can also be successfully used).
- Winding. There are several options here: Packl or rubber tape. You can use it with an equal degree of success, both of them, it is as convenient for anyone.
The procedure for installing the installation of water meters is as follows:
- First of all, it is necessary to block the risk of water supply. In this case, you must definitely notify the neighbors about this. If someone at this time will work as a washing machine, there will be a lot of problems.
- After that, the old crane is dismantled. Gently, with the help of a water key, the pipe is supported, and the tap is removed with a wrench. If it is not unscrewed, you can use the lubricant WD-40. When the crane is unscrewed, it is necessary to inspect the condition of the thread on the pipe. In the case of an unsatisfactory state, it must be cleaned or re -pass by a dick of the corresponding diameter. The thread is tightened with winding. If the package is used, it can be lubricated with any thick lubricant, for example, by solidol. The tap on the thread is wound with average effort. You do not need to overdo it here, since you can just tear the thread.
- Next, a mesh filter is installed. You must be careful so as not to put it the other way around. There is an arrow on its case, which indicates the direction of the flow of water. That is how it needs to be installed. The filter on the crane carving is wound.
- The next step is a coupling with a rug nut. It is screwed into the filter thread external threads. It is these threads that is motionless. The nut can always be untwisted and removed for verification.
- A check valve is installed on the back of the pipe. It is needed so that there is no way to “unscrew” the counter back. The valve passes water in only one direction. All connections are compacted by winding. A second clutch with a rug nut is screwed to the inner thread of the check valve.
- Further, between the two pitch nuts, it is necessary to install a cold water meter. It is also important not to confuse the sides so that it does not spin in the opposite direction. To do this, the appropriate marks are installed on the device housing. The counter is installed simply. Supplies are installed inside the union nut. They can be made of paronite, rubber or silicone. The first option is better for hot water, the second for cold. Rubber gaskets are now rarely put. After installing the gaskets, the nuts are easily clamped, supporting the counter body with a key.
- Next, when the system is assembled, you can connect the riser to the water supply. Just in case, you need to lay a rag or substitute a basin of water. At the same time, the cut -off valve must be closed.
- After water is turned on, first of all, it is necessary to check the presence of a leak between the tap and the pipe. If she is, you need to carefully squeeze the crane. If it is not, the tap open and check all other connections. Checking the availability of leaks is carried out using toilet paper. The fact is that even weak drops of water are visible on it. It is simply necessary to draw a small piece in places of joints and look at the result. In the case of a leak, the connection is pressed. If there is still a leak (this is the most unpleasant moment) will have to overlap the crane and reuper the connection.
- After the counter is installed, it is necessary to call the work with subscribers and call a specialist. He will come, check the documents and carry out sealing. The results of the first readings of the counter will become the reference point for the consumed water.
