By the nature of its activities, working as a plumber, I have to install water meters. Sometimes, after the installation of meters, customers call me and say that the water meter when said cubic meters of water consumption does not. For all the practice time accumulated four Fault running water in which the counter turns reading independently.
REMEMBER - More than one water meter can not twisted without external influence. In this case, through the impeller, in the photo below, must pass a moving fluid. Only under this condition, the counter readings winds.
Why counter continues to count when the valve is closed?
Improper installation Instruments of the calculation of water, where the water can enjoy your neighbors, but will pay for the water you. This usually occurs in communal apartments. If the installation of water meters produced no expert, he does not always pay attention to the hidden wiring of the water supply. There are cases that are neighbors with water from your water supply.
How to fix? Produce the correct installation of water meters. Neighbors mount separate branch water from your riser.
Defective water mixer.
After faulty mixer possible overflow of hot water in the cold water supply. When the valve is closed counter to the hot water starts to wind readings water in a big way. A counter cold water into smaller. In my practice was a case that went to the cold-water meter readings to 99998 cubic meters. Ie clocked in the opposite direction.
How to fix ?1)repair of water is required to switch on the mixer shower head. 2)In the old Soviet mixers require replacement pads (an unlikely event). 3)Installing the check valves on the pipeline HVS. 4) Replacing the mixer.
Incorrect installation of electric boiler water.
Some owners of apartments set flow or storage water heaters. Use it during WAN outage. If check valves are not installed on the pipeline of the central hot water can crossflow water. In this case, counters will be spinning again as in a faulty mixer.
How to fix ? Set-return valve for hot pipe. Be sure to overlap the central valve on the hot water riser pipe during the use of water heaters.
A leak in the toilet.
After installing the new meters may wrap indications of cold water. This is due to the fact that a new device sensitive to water flow. Unnoticed leaks, valve fittings toilet tank. Visually, the small leak can not be seen. I usually check using toilet paper. If the valve is working properly the water will not soak the toilet paper.
