Varieties of water meters

In today's market you can find a wide selection of meter models, which are characterized by a wide variety and various properties. Therefore, before performing the repair of the water meter with your own hands, you need to understand what they are and how they differ.

Popular models:

  1. Electronic. They are resistant to increased water pressure in the system. Even with a minimum pressure of water, the device is able to record the indications of its consumption. Due to the presence of roller and dial indicators, it is very convenient for users to read readings. You can install such a meter horizontally or vertically. To perform a metrological check of the device, it is enough to remove only its upper part, while the remaining parts remain articulated with the pipes.
  2. Mechanical. More often, such devices are assembled from imported components, which is why they are in no way inferior to foreign models in their quality characteristics. In trade, mechanical water meters are presented in a huge assortment. Compared with electronic counterparts, they are much cheaper.

Features of self-repair counter

Such devices should only be repaired at the installation site. But before you repair the water meter yourself, you must carefully examine its design. As a rule, they consist of an impeller through which water flows. It is she who twists it, due to rotation, the gear system begins to move, while it is connected to the counting mechanism. This design is located in a metal case from the bottom, and in a transparent top.

Common causes of malfunctions:

  1. Clogged with plaque of rust or solid particles.But if a rough filter works in the apartment, then such a phenomenon is unlikely.
  2. Impeller breakage or wear.
  3. Gear wear in the counting mechanism.
  4. Damage to the case or exposure to low temperature. Often the meters freeze outside in the winter.

Important! As soon as you find a breakdown, immediately contact the accounting organization, since only it has the right to issue you permission to remove the seal. If you remove it arbitrarily, then you face a large fine.

As soon as you receive such permission in writing, you can safely proceed to dismantle the device.

Dismantling the water meter from the video

Carry out the removal as follows:

  • Turn off the water through the valve that is installed on the water inlet to the house or apartment. Such valves must be installed in front of the devices.

Important! If there is a central hot water supply, you will also have to close the hot water valve.

  • Open cold water to remove residual water from the system.
  • Unscrew the union nuts on the counter, remove it.

Important! Be sure to install a metal insert in place of the device, then to resume water supply.



To identify a problem and solve it, follow these steps:

  1. Blow out the device. Just blow it well into the inlet.
  2. If it remains in a stationary position, then rinse it under strong pressure of water in order to wash away the deposits of rust and debris.
  3. If the wheels start spinning during the re-purge process, then you have managed to fix the problem.
  4. If the purge did not help, it means that something inside has broken, and you will have to completely remove the case. Disassemble the counter, remove the top, counting mechanism, scoreboard, impeller. It will not be difficult to identify the problem here.
  5. Replace worn parts, return everything to its place.

Important! Putting the seal back on its own will not work, so either try not to destroy it during the repair process, or call the wizard to reseal it.

If the mechanical part of the case has been damaged, most likely you will have to change the water meter or find a faulty device with the whole case and just swap them. Then you will need to install it in place, following this instruction:

  1. Block the water at the inlet.
  2. Get rid of residual water in the pipes by opening the mixer.
  3. Remove the metal insert, put a water meter in its place. At this stage, it is better to put new gaskets under the union nuts.
  4. Open the water. If water starts to flow from under the nut, tighten it harder.

Useful Tips

Despite the fact that it is not difficult to repair water meters with your own hands, the following nuances should be taken into account:

  • If you have never performed plumbing work before, then you are unlikely to find the necessary spare parts in your arsenal, which are rarely even found on sale.
  • Think carefully before fixing the meter with the seal installed on it, because you most likely will not be able to keep it intact, and this is an additional cost in the form of penalties.
