The water meter is a measuring instrument in each of our families. It is specially used to measure our daily water consumption. If it is found that the water meter at home is running too fast during use, we must find out the reason as soon as possible and take corresponding measures according to the reason to avoid expenses. Unnecessary water bills. So what are the possible reasons why the water meter runs too fast? How to solve them?
- The water meter is too old
If the water meter runs too fast, it may be that the service life of the water meter is too long. Some water meters have been used for a long time, the measurement accuracy is reduced, the internal wear of the water meter is serious, and the water meter runs faster. According to the regulations of China's Technical Supervision Bureau, the service life of civil water meters (DN15mm-25mm) generally shall not exceed 6 years. The service life of water meters (above DN40mm) shall not exceed 4 years. If the service life expires, it is better to replace it with a new one.
- There is air in the water pipe
For the newly installed water meter, because there is air in the water pipe, the water meter may run faster when the tap is turned on to exhaust air. When installing water pipes, when there is a turn or a right-angled bend, there may be air reserved at the top of the water pipe bend. When the faucet is turned on, the water flow speed will increase and the pressure will decrease, resulting in split pipes. becomes smaller, thereby driving the water meter to run faster. As long as you turn on the faucet and let some water flow out, it will return to normal after emptying the air in the water pipe, so don't worry too much.
- The pipe is leaking
If the water meter at home runs faster than usual, there is another possibility, such as the toilet or some pipes leaking, which will cause the water meter to turn faster. In this case, it is necessary to check in time whether there are water leaks in the home, and if there are, it must be repaired in time, so as not to infiltrate the floors below and cause bigger problems.
- The water meter has quality problems
The water meter may turn too fast because of the quality problem. At this time, you need to find the property management or the original manufacturer of the water meter to conduct relevant inspections and appraisals. If there is a problem with the water meter, it must be repaired. If it cannot be repaired, the water meter must be replaced in time. Therefore, it is recommended that when choosing a water meter, it is best to choose a water meter manufacturer with a quality inspection link to fundamentally avoid this problem.
Generally speaking, ultrasonic water meters usually have a longer service life than mechanical water meters. Since ultrasonic water meters have no internal mechanical moving parts and mainly rely on electronic components and sensors to measure water flow, the impact of mechanical wear and scaling is reduced, the overall maintenance requirements are low, and the service life can reach 10-15 years or longer. Mechanical water meters rely on internal mechanical parts such as gears and turntables for measurement. These parts are easily worn out during long-term use, resulting in reduced accuracy or failure, and the service life is usually 8-12 years. Therefore, ultrasonic water meters are more durable and more stable.
