Water use guidelines

 
Common sense of water use

   1、 Why can't the water meter be moved without permission

The water meter device is determined according to the architectural design, and the property right belongs to the water supply enterprise. If the meter position is moved privately, it will not only violate the relevant provisions of the regulations on the management of urban water supply and water saving in Ningbo City, but also affect the daily meter reading and maintenance, and even damage the water meter, resulting in water consumption difficulties.

   2、 How to view water meter consumption

1. At present, the unit of charge for meter reading is cubic meter (i.e. ton). The actual water quantity of the current period can be obtained by subtracting the water meter indication of the current period from that of the previous period.

2. The display mechanism of the early water meter was full pointer type, with 10 times progressive counting system. There were seven pointers, representing four digits (black disk), and three digits (red disk), namely 0.1, 0.01 and 0.001, respectively. The calculation unit was cubic meter (ton). When reading the table, you should master the carry method. If a bit pointer does not go to 0, ten digits means that the number will not carry, and so on.

3. At present, the water meter display mechanism used in many residential areas is a combination of word wheel and pointer, which can be read directly from left to right according to the black indicator. The unit of measurement is cubic meter (ton). When reading daily, the red indication can not be read.

   3、 Why does tap water sometimes turn yellow

1. The yellow water phenomenon is particularly obvious when the water is first used in the morning, which is mainly caused by the user's indoor pipeline being out of repair for a long time or using inferior pipes. Users should consider updating indoor pipelines.

2. It is found that the water quality of a building or several buildings is yellowing, and it can not be discharged for a long time. The main reason is that these users are at the end of the outdoor common water distribution pipe. If the outdoor pipeline distributing water for users is at the end of the water supply pipeline, the rusty water quality in the pipe network enters, and the water consumption of the user cannot be discharged, a section of rust water area will be formed over time, and the users who use water on this section of pipeline will feel the water quality is yellow and unable to use water. In this case, users should contact with water supply enterprises in time and take corresponding measures to solve the problem.

   4、 How to do if the water meter is damaged by freezing, scalding and smashing

"Ningbo City water supply and water conservation management regulations" stipulates that users have the obligation to maintain the sanitation of water meter wells and the normal operation of water meters. After the water meter is damaged, the user shall not repair it by himself. Instead, the valve in front of the meter shall be closed to avoid water loss, and the water supply enterprise shall be informed to replace it in time.

   5、 How to find water leakage

Indoor water leakage: first check all water equipment (faucet, shower, toilet, etc.), valves and meter well for water leakage. If there is no water leakage in the above equipment, then look at the movement of the charging water meter. If the water meter continues to rotate at a constant speed when the water is not used, it indicates that there is water leakage. Please inform the property right unit to check the leakage.

Water leakage of toilet: except for obvious dripping sound, it can be determined that there is water leakage in the toilet. Generally, it is not easy to detect. The simple inspection method is to drop blue ink into the toilet water tank, and then check the toilet water outlet after mixing. If there is blue water outflow, it indicates that the toilet has water leakage.

   6、 Why does tap water have the smell of disinfected water

In order to ensure that the tap water meets the safety and health requirements and avoid the occurrence of water-borne infectious diseases, the tap water is chlorinated and disinfected in the process of water purification, and meets the residual chlorine range specified in the hygienic standard for drinking water. For ordinary people, tap water of this concentration will not smell or drink obviously. Only a few people who are sensitive to smell or taste will feel the smell of disinfected water, which has no impact on human health. Tap water has a slight smell of disinfection, indicating that the water quality is hygienic and safe.

   7、 Why is tap water sometimes muddy and white

1. The main cause of muddy water is the actual burst of urban water supply pipeline. After rush repair, due to the change of water flow direction and water pressure, local and short-term muddy water phenomenon may be caused, which will soon return to normal.

2. The main reason for whitening is that air is dissolved in the water supply pipe network, which is decomposed into tiny bubbles (which can not be observed by naked eyes) under pressure. When the bubbles are closely arranged, the outflow water will be milky white. When it is still in the container for a few minutes, the water will become clear with the disappearance of bubbles. This phenomenon will not affect the quality of tap water.

   8、 General causes of vibration and noise of indoor water pipes

Sometimes, the indoor water pipe will vibrate and produce noise, which will affect the living environment of residents. In fact, the causes of vibration and noise are very complex. Generally, there are several reasons, such as high water pressure in the pipe, air in the pipe or damage of pipe fittings

1. The pressure reducing valve in the high-rise building is out of order and the pressure in the water pipe is too high.

2. The water pressure in the area is too high intermittently, which causes the vibration of indoor water pipe.

3. When the indoor pipeline is newly built or refitted, the pipeline direction is unreasonable, which makes the air accumulated in the ceiling or high water pipe.

4. The fittings in the toilet are damaged, and the air enters the water pipe from the toilet.

5. Air accumulates at the end of the pipe, which causes vibration when the water pressure changes, and is transmitted to the indoor pipeline.

6. The outdoor water inlet pipe leaks. When a large amount of water is used indoors, the instantaneous negative pressure of the outdoor water inlet pipe is caused, and the air enters the indoor pipe with the water flow and accumulates.

7. The floating ball valve of multi-layer roof water tank fails, and the floating ball hits the water tank wall, and the noise is transmitted to the room through the pipeline.

8. The valve plate of one-way valve in the pump house of the community is out of order, causing intermittent shaking, and the noise is transmitted into the room from the pipeline.

9. The valve chip on the pipeline is loose or the user's faucet is unqualified, and the metal collision causes vibration when the water flows through.

In fact, most of the water pipes vibrate because there is air in the pipes, and the air can't be discharged. Under the action of pressure, obvious vibration will be produced. The greater the pressure, the greater the vibration. Therefore, in general, when the vibration noise of water pipes is generated, turn on a small number of taps to discharge water as much as possible, or close the water inlet gate, which can alleviate or eliminate the water pipe vibration Move.

   9、 How to do a good job in antifreeze and warm keeping of water equipment

1. The anti freezing of outdoor water pipes and faucets can be wrapped with cotton, hemp fabric or thermal insulation materials.

2. In the cold season, please close the corridor and indoor doors and windows before going to bed to keep the room temperature. At the same time, close the household meter valve and turn on the tap to drain the remaining water in the water pipe.

3. For the frozen faucet, water meter and water pipe, it is advisable to wrap the faucet with hot towel first, then pour warm water to thaw the faucet, then turn on the faucet, and slowly sprinkle warm water along the faucet to thaw the water pipe. If there is no water flowing out from the water meter, it means that the water meter is also frozen. At this time, wrap the water meter with hot towel and sprinkle it with warm water (no higher than 30 ℃) to thaw the water meter. Do not bake it with fire.

   10、 How to deal with sudden water cut off at home

If the user suddenly stops water supply without receiving the notice (if there is a planned water cut-off, it will publish "water cut-off notice" in "Ningbo Evening News" 24 hours in advance or inform the community property; if there is a sudden burst of water, the important users will be informed at the same time of emergency repair). First, they should ask the neighbors whether there is water, and then check whether the water meter valve is opened normally, or call our company Qingquan hot Line 96390.
