What's wrong with the water meter without running water?

One of the reasons: the indoor water heater leaks.

There are many kinds of household water appliances. If there is water leakage, users can find and repair it in time. However, the leakage of toilet water storage tank in household water appliances is not easy to find, which is easy to cause the water meter to rotate. There are two main leakage points: first, the floating adjustment of the water storage tank is too high or fails, which leads to the tap water flowing out of the overflow port of the water storage tank and the water meter rotating. The solution is to lower the floating position or replace the faulty parts. Second, the aging or non-return of the rubber plug at the outlet of the water storage tank will cause the water meter to rotate. When the water leakage is large, it can be supplemented with the leakage, and the pointer of the water meter rotates evenly and smoothly; Intermittent water replenishment can occur when the water leakage is small, which makes the water meter stop once, and the interval varies from several minutes to more than ten minutes. The solution is to replace the damaged parts.

The second reason: the old doormat is damaged.

Most of the old cut-off doors are opened in a spiral way, and the new cut-off doors can only be fully opened at 720. When users of the same pipeline run out of water, the pressure on the old intercepting door is several times that on the new intercepting door. When the old-fashioned door fender pad is damaged and the water leakage is not obvious, the pointer of the water meter does not move, and when other users on the same pipeline use up water to close the door fender, the water pressure increases, which leads to the tap water flowing out from the damaged part of the old-fashioned door fender pad and makes the water meter rotate. The solution is to replace the damaged parts.

The third reason: the indoor water supply pipeline leaks.

Generally, when the indoor water supply pipeline leaks, users can easily find it, and only need to find a property right or property management company for maintenance. However, some users on the first floor buried the indoor water supply pipeline in the ground during the renovation. When the water supply pipeline leaks, the water will directly leak into the ground, and the user can't find it in time, but the pointer of the water meter rotates evenly and smoothly. The simple judgment method is to turn off all water-using equipment, and check whether the pointer of the water meter rotates evenly and smoothly when no other water-using equipment leaks water. If there is any movement, it means that the water supply pipe is leaking.

The fourth reason: there is gas in the water supply pipeline to form a water hammer.

The gas in the water supply pipe is another reason why the water meter turns. When there is air in the water pipe, because water can't be compressed physically, the air can be compressed. When the user turns off the faucet, the inertia pressure in the water pipe increases instantly, and the air in the water pipe is compressed and then bounces back, forming the water in the water pipe surging back and forth. Because of the pressure change in the water pipe, the water meter may also "reverse", and these fluctuations are within the error range of the water meter. Generally speaking, users' profits and losses are basically flat, and ordinary people will not pay more for water. There are many reasons for air intake in the pipeline. One is the newly opened house, the indoor pipeline design is unreasonable, and the user arbitrarily transforms the pipeline, resulting in air in the water supply pipeline. The solution is to close the main water inlet valve at home, open all faucets and plugs at home, and then open the main water inlet valve to drain water 1-2 minutes for exhaust. Secondly, under the action of water pressure, water will also be pressed into some water appliances that have space or will expand and deform after being pressed, such as the water storage tank of water heater, the water storage tank of toilet, the water inlet hose of washing machine and water heater, etc. The solution is to install a partition door in front of these water appliances and close it when not in use. At the same time, users are advised to close the indoor water main valve when they are away from home for a long time.

The fifth reason: stealing water downstairs.

Because your own water pipe must go downstairs to the bathroom or balcony (not the first floor), if you meet someone with poor quality, add a tee on your water pipe, and he can use your water without affecting your use, which is difficult to find. Another wise man, adding a regulating valve on the tee can control the flow of stolen water, and he can choose the water pipeline.
