Tips for freezing prevention of tap water pipeline in winter

1. How to prevent water pipes from freezing in winter? What are the anti-freezing skills of water pipes?

Anti-freezing skills of water pipes:

1, water pipes, water meters, faucets and other water facilities in residents' homes can be tightly wrapped with thermal insulation materials (glass fiber cloth, cotton and linen fabric, plastic foam, straw rope, etc.). ), and the water supply facilities in the shade should be thickened and tied. Indoor water meters can also use the antifreeze cover of water meters.

2. Close the windows of corridors, kitchens, toilets and all shady rooms at night to ensure that the indoor temperature is above zero degrees Celsius. At the same time, close the indoor water meter valve, turn on the faucet, and let off the remaining water in the water pipe.

3. In cold weather (below minus 3℃), after using water at night, slightly unscrew the faucet to keep the faucet dripping, so as to ensure the running water in the water pipe and prevent it from freezing at night.

4. For the roof water tank, the top cover of the water tank should be covered, and the upper and lower water inlet pipes and valves of the water tank should be tightly wrapped with thermal insulation materials. For outdoor installed water pipes, water pipes and valves can be wrapped with warm goods (such as cotton, cotton cloth, linen, straw belts, straw ropes, etc.). ). The plastic wrap should be kept dry, waterless and tightly wrapped, and then wrapped in plastic bags (films) or plastic tapes.

2. How to prevent water pipes from freezing teaches you how to prevent water pipes from freezing.

It goes without saying that water pipes play an important role in our life, but in cold winter, water pipes often freeze. So what are the ways to prevent water pipes from freezing? Let's take a look at them together.

What are the anti-freezing methods for water pipes? What's the trick to prevent water pipes from freezing? -Turn on the tap. In the cold winter, due to the low temperature, it is easy to freeze the water pipes. What should I do in the application of water pipe antifreeze? Below, I will give you some preventive measures to prevent water pipes from freezing. At night when the temperature is very low in winter, you can turn on the tap a little bit to let the water flow out continuously. The flowing water can effectively prevent the water pipe from freezing even in a cold environment.

When you turn on the tap, you need to pay attention to the fact that only a small flow of water is needed. If the water flow is too large, it is very uneconomical to waste too much water. Anti-freezing of water pipes-It is relatively simple to wrap indoor water pipes for anti-freezing in facilities engineering, but it will be more troublesome to wrap outdoor water pipes for anti-freezing. When the outdoor water pipe freezes, you can wrap the faucet with cotton and linen and straw rope, and at the same time wrap the water pipe tightly with cotton and linen fabric or antifreeze sleeve. It is best to wrap several layers of water pipes, which can effectively strengthen the warmth of water pipes and prevent them from freezing.

The pipes at both ends of the water meter and the exposed pipes on the ground should also be wrapped with cotton cloth, and the water meter box should be kept dry and tightly covered. After it snows, the snow on the water meter box should be swept away in time to prevent the snow from flowing into the water meter box after melting. Insulation method: the pipes at both ends of the water meter and the exposed pipes on the ground can be wrapped with cotton cloth; Keep the water meter box dry and cover it tightly; After it snows, the snow on the water meter box should be swept away in time to prevent the snow from flowing into the water meter box after melting.

Drainage method: when tap water is not used (especially at night), the front valve of the water meter can be closed, and the rear valve and faucet can be opened to drain the tap water in the pipeline; When the temperature is extremely low, it is best to unscrew the tap slightly after using water at night to make the water flow into a line to ensure the flow of tap water in the water pipe. Heating method: once the water meter and water pipe freeze, the room temperature can be raised by coal stove and heater or melted by hair dryer and hot towel. Do not splash water meters and pipes directly with fire or boiling water.

How to prevent water pipes from freezing ① Indoor water pipes and water meters are frozen, mostly because the heat preservation is not in place or the doors and windows are not well sealed. People should close the windows of kitchens, toilets and shady rooms at night to ensure that the indoor temperature is above zero; (2) For outdoor water pipes and water meters, heat preservation measures must be taken, and water pipes, water meters and faucets can be wrapped with heat preservation materials such as cotton and linen fabrics and plastic foam; (3) The water meter well should be filled with sawdust or other thermal insulation materials, covering 20 cm above the water meter to prevent frost cracking and facilitate meter reading; (4) Before going to bed, it is also a good way to prevent the water pipe from freezing and cracking by turning off the water meter valve and turning on the faucet and letting off the remaining water in the water pipe. ⑤ Turn down the faucet at night when the temperature is very low, so that a trickle of water can flow out continuously.

This can effectively prevent the water pipe from being frozen. Maintenance method of water pipes 1.

Facing the low outdoor temperature in winter, it is suggested to put cotton and linen fabrics, plastics and foam. On the water pipe, that is, a layer is wrapped around the water pipe, and it is better to wrap a layer of plastic cloth outside, which has a certain thermal insulation effect. 2。

In addition to outdoor water pipes, pay attention to antifreeze and warmth, and indoor water pipes should also be paid attention to. At night, the balcony, kitchen, bathroom and doors and windows facing north should be tightly closed to ensure the indoor temperature and avoid freezing indoor water pipes. 3。

After the water is stopped at night, the valve in front of the water meter can be closed and the water can be stored in the civil air defense pipeline. No matter how low the temperature is, water will not freeze when it flows in the tap water pipe. It is suggested that in areas where the temperature is below 5℃ in winter, the faucet should be slightly turned on at night to let the water flow to prevent freezing.

If the faucet can't be used normally due to freezing, don't twist it hard, and don't use pliers and other tools to start it hard. The correct way is to wrap it with a towel and other packages, and then pour hot water along the faucet in the direction of the water pipe to thaw it. Discarding finished.

3. What are the anti-freezing tips for water pipes?

Tap water pipe is an indispensable and important object in our family life. It is simple and convenient to use in life, but there are also some problems. In winter, due to the low temperature, water pipes are easy to freeze due to the influence of low temperature, especially in some cold northern areas. What if the water pipe freezes? Is there any way to deal with the antifreeze problem of water pipes? What are the tricks to prevent water pipes from freezing? Don't worry. Here is a detailed introduction to the anti-freezing method of tap water pipeline.

What are the anti-freezing methods for water pipes? 1. In the north where the temperature is underground, you can wrap a layer of cotton and linen to keep warm when the water pipe is antifreeze. You can wrap the hose beautifully. Intentional owners can also doodle on the water pipes, which can beautify the effect and protect the water pipes well. 2. Improve the indoor temperature. The indoor temperature is also relatively low in winter. If you leave the doors and windows open at night, the indoor temperature will be lower, so even the indoor water pipes will freeze.

Therefore, if you want to prevent indoor water pipes from freezing in winter, you can raise the indoor temperature, turn on some heating properly, or choose thicker curtains. 3, dripping antifreeze We all know that flowing water is not easy to freeze, so the best way to prevent water pipes from freezing is to keep the water flowing. Although this method can prevent water pipes from freezing, it will waste some water resources.

Insulation method of tap water pipe: the pipes at both ends of the water meter and the exposed pipes on the ground can be wrapped with cotton cloth; Keep the water meter box dry and cover it tightly; After it snows, the snow on the water meter box should be swept away in time to prevent the snow from flowing into the water meter box after melting. Drainage method: when tap water is not used (especially at night), the front valve of the water meter can be closed, and the rear valve and faucet can be opened to drain the tap water in the pipeline; When the temperature is extremely low, it is best to unscrew the tap slightly after using water at night to make the water flow into a line to ensure the flow of tap water in the water pipe.

Heating method: once the water meter and water pipe freeze, the room temperature can be raised by coal stove and heater or melted by hair dryer and hot towel. Do not splash water meters and pipes directly with fire or boiling water. Water pipes, outdoor pipes and faucets, etc. , should be wrapped in cotton and linen fabric, plastic foam and other thermal insulation materials, and do a good job of thermal insulation.

The water supply facilities in the water meter well (water meter box) can be covered with old cotton wool, straw mats and other warm items. Clean up the snow on the water meter manhole cover in time after it snows to prevent the snow from flowing into the water meter well after melting.

2. When going out for more than two days, please close the tap water valve behind the water meter, and empty the pipeline and water-using equipment, such as the tap water in solar energy, to prevent the water pipe from freezing or freezing, causing water leakage and bubbles and bringing unnecessary losses to life. 3. For water users with low occupancy rate and long-term uninhabited property units in newly-built residential quarters, especially in the coldest months of 65438+February and 65438+ 10 and February, please go through the formalities of stopping water use in time; Close the water valve in front of the instrument to drain the remaining water in the pipeline.

4. When replacing the thermal insulation material of the water meter well, first check whether the bottom of the water meter and the water pipe are padded. After confirmation, wrap the insulation materials in snakeskin bags or other packaging bags, and don't tie the mouth too tightly. Fill the water meter and take it out one by one during meter reading, which is convenient for meter reading and keeps the meter well clean. Discarding finished.

4. Common sense: Teach you how to prevent water pipe faucet from freezing.

According to past experience, the freezing weather of rain, snow, strong wind will have a great impact on urban traffic, water supply and power supply. Nanchang water supply department has issued anti-freezing tips for water supply facilities.

Nanchang water supply department reminds the general public to make timely preparations to avoid freezing of outdoor water pipes and water meters caused by sudden drop in temperature, which will affect normal water use. Users who install pipelines in the north and windward side should pay special attention.

In addition, galvanized iron pipes are easier to freeze than hot melt pipes, and should be fully insulated and bandaged. At the same time, the water supply department reminds all owners, property management companies and residents to do a good job of anti-freezing and heat preservation of water facilities such as residential pipelines, building risers and roof water tanks in advance.

For the water meter installed outdoors, you can choose a thick towel or cloth to wrap the water meter, or you can turn on the faucet at home to let the water flow out in a linear way and let the water in the water pipe move, so as to prevent the water meter and water pipe from freezing. If the water meter has frozen, wrap it with a hot towel and sprinkle it with warm water (not exceeding 60 degrees Celsius) until the ice in the pipe melts and the water flows out smoothly. Do not pour boiling water or bake with fire to avoid damaging the plastic parts in the water meter.

Outdoor exposed water pipes and indoor water pipes can be wrapped with thermal insulation materials (such as old clothes, cotton wool, sponge, etc.). ), and a layer of waterproof material (plastic sheets, etc.). ) wrapped in insulation materials to prevent them from freezing. If the faucet and water pipe are frozen, you can blow them with a hair dryer, or wrap them in a towel and slowly pour in warm water. At the same time, you can tap the water pipe gently with a hard object until the ice in the pipe melts and the tap water flows out smoothly.

5. How to prevent household tap water from freezing in winter?

1, put a coat on the water supply pipe.

In the north where the temperature is underground, you can wrap a layer of cotton and linen around the water pipe to keep warm when the water pipe is antifreeze. You can wrap the water pipe beautifully when you wrap it. Interested owners can also doodle on the water pipes, which can beautify the effect and protect the water pipes.

2, improve the indoor temperature

The indoor temperature is also relatively low in winter. If the doors and windows are not closed at night, the indoor temperature will be lower, so even the indoor water pipes will freeze. Therefore, if you want to prevent indoor water pipes from freezing in winter, you can raise the indoor temperature, turn on some heating properly, or choose thicker curtains.

3. Drop antifreeze

Flowing water is not easy to freeze, so the best way to prevent water pipes from freezing is to keep the water flowing. Although this method can prevent water pipes from freezing, it will waste some water resources.

4. Drain the residual water in the water pipe.

Because some of the above methods will waste water resources, here is another method, that is, pull down the sluice at home in winter, and then drain the water in the water pipe, so that the water in the water pipe will not overflow, but remember to keep the sluice warm.

Disinfection method of tap water:

At present, most tap water is chlorinated. The main purpose of chlorination of public water supply is to prevent water-borne diseases. This method has been popularized for more than 100 years, and it has relatively perfect production technology and equipment. Chlorine used for disinfection of tap water has the advantages of good disinfection effect, low cost and almost no harmful substances.

However, after understanding and studying the theoretical data, it is found that chlorine still has some disadvantages in disinfection of tap water. Chlorinated tap water will produce carcinogens. At present, relevant experts have put forward many improvement measures.

Chlorine is dissolved in water and reacts with water to produce hypochlorous acid and hydrochloric acid, and hypochlorous acid plays a major role in the whole disinfection process. For inorganic substances with peculiar smell, they can be thoroughly oxidized and disinfected. For algae, bacteria and other living natural substances, they can penetrate the cell wall, oxidize their enzyme systems (enzymes are biocatalysts), inactivate them, hinder the life activities of bacteria and die.

Hypochloric acid itself is close to neutrality, easy to approach bacteria, showing good bactericidal effect. Hypochlorite ion also has a certain disinfection effect, but it is difficult to get close to negatively charged bacteria (negatively charged bacteria), so its disinfection effect is much worse than hypochlorous acid, so chlorine disinfection effect is better than bleaching powder disinfection.
