Shock when not using water, the water meter still rotates

Shock with the phenomenon of not using water, the water meter still rotates in many apartments and high-rise units recently encountered. In a short time, we received quite a lot of information reflecting that people living in the same base are not using water but the water meter is still bewildering for people in these apartments and some other apartments. To find out about the fact that when the water meter is not running, we have come to experiment and experiment to produce the following result.

Shocked with the phenomenon of not using water, the water meter still rotates in many apartments and high-rise units recently encountered. In a short time, we received quite a lot of information reflecting that people living in the same base are not using water but the water meter is still bewildering for people in these apartments and some other apartments. To find out about the fact that when the water meter is not running, we have come to experiment and experiment to produce the following result.

At condominiums such as the police department apartment in District 2, we met directly some of the households living here and they shared quite honestly about what they worried about that at some time. water for their family has no use of water, but observed that some of the clock hands have a slight rotation phenomenon. After being reflected we contacted the technical manager here and have them experimented at the water meter technical department. After we arrived at the installation of the water meter we observed several times and saw the same phenomenon. But also here we found a problem in the installation department, or it can be said that a technical error is that all water meters are not equipped with a one-way valve assembly.

After recording and observing the actual situation in the apartment building of District 2 Police, we also went through Vinhome 6 apartment in Phu Nhuan district to review and also recorded a similar case reflected by the people here. When contacting the technical management, we are quite surprised that there is the same mistake that is missing the 1-way valve assembly before and after the water meter.

After observing the scene of the absence of water, the water meter still rotates in many apartments, we can explain as follows.

Water meters are installed in parallel manner through a straight line of branched pipes, but lack of one-way valve valves installed in front of the meter to prevent blocking and backflow so when not using water but it only takes one or two houses and the system uses water to create the force flowing on the pipe and create inertial whirlpools at the folding points thus making the water fluctuate on the water meter in unused families. it spins. This phenomenon is not only later that the units installed in the apartment, they have less one-way valve that happens on it again only.

So the phenomenon of not using water but the water meter is still rotating is not difficult to understand, is it not for the whole family, and people need to understand one more thing is that mechanical water meter needs mechanical force to operate so if If there's no impact force, it won't spin. ^^

note / another reason is that the indoor pipe has leaked or broken somewhere but the owner does not know you should check carefully
