The water meter at home is idling, what is the reason?
In the case of no water leakage at home, this idling is mostly caused by changes in external water pressure and air in the water pipes in the home.
When the water pipes in the home are arranged more than the faucet (usually close to the roof), open the faucet when the water is cut off, the water will come out, and the air will go in; after the water is turned on, there is still some air left in the water pipe In this case, when the external water pressure is high, the air part is compressed, the water meter turns and starts to count, when the external water pressure is lower than the home water pressure, part of the water in the home water pipe will go to the outside The water pipe will return, but the water meter will not be reversed. Every day when a neighbor uses water, the water pressure will change, and your water meter will continue to count, so your water meter has a water count when there is no water use and water leakage. The number of water meters depends on the number of water pressure changes and the amount of air in the water pipes.
Solution: 1. When the water valve in front of the water meter is open, turn on all the faucets in the house and discharge the air in the water pipes as much as possible, which can improve the idling situation. 2. Install a one-way valve (check valve) in front of the water meter (or near the water meter behind the meter), which can basically solve the idling situation.
