Common sense of cold protection of tap water

1. Anti-freezing method of water pipes What should I do if some water pipes freeze?

First, anti-freezing common sense

1. "Wear a hat": Exposed water facilities such as water pipes, water meters and faucets can be wrapped with thermal insulation materials such as cotton and linen fabrics and plastic foam, especially if the water meter box is located in an open corridor, it can be thickened and wrapped with cotton and linen fabrics and plastic foam discarded at home.

2. "Close the windows to prevent cold": In cold weather, especially at night, please close the windows of the balcony, kitchen, bathroom and all rooms facing north to ensure that the indoor temperature is above zero.

3. "Dripping water into a line": In cold weather, if the temperature is below 0℃, you can slightly unscrew the faucet at night to make the water flow into a line to ensure that the tap water in the pipeline can flow and prevent freezing at night. Please use buckets and other suitable water storage equipment to receive water and save water.

4. "Drainage facilities": Turn off all faucets, especially the water tanks or pipes of water-using facilities such as water heaters, solar energy and washing machines, so as not to affect the facilities. The pipes at home can also be emptied to reduce the pressure in the pipes and prevent freezing damage.

5. "Thawing measures": For water facilities such as faucets, water meters and water pipes that have been frozen, hot towels can be applied to the water pipes and then thawed with warm water of about 30℃. Never bake it directly with fire or scald it with boiling water, lest the water pipe or water meter burst.

6. "Water security": If necessary, please reserve some domestic water in advance for basic needs.

Second, a warm reminder

1. If you have time to close the room or need to go out for many days, when there is no one at home, please close the water inlet valve in front of the water meter at home before leaving home and drain the tap water in the pipeline to prevent unnecessary losses caused by people who are not at home when the water facilities are broken.

2. In cold weather, your home may have no water or little water, which basically belongs to the frozen state of the pipeline. Please wait patiently for the natural thawing, and don't be nervous.

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. Common sense: Teach you how to prevent the 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.

4. How to prevent freezing of water pipes at home in winter?

1. Exposed water supply pipes, water meters and faucets can be wrapped with cotton and linen fabrics, foamed plastics or other professional thermal insulation materials.

2. Close the doors and windows at night to ensure the indoor temperature is above 0℃. In case of severe cold weather (below minus 3℃), the most effective way to prevent the faucet from freezing is to gently unscrew the faucet after using water to keep the tap water flowing in the water pipe.

Please close the doors and windows and keep the room temperature before going to bed. At the same time, close the water inlet valve of the water meter, turn on the faucet and drain the remaining water in the water pipe.

4. Cover the top cover of the water tank on the roof, and wrap the water inlet pipe, valve, water supply pipe and other facilities of the outdoor water tank up and down with insulation materials (such as foam insulation pipe, asbestos products, straw rope, old cotton-padded clothes, etc.). ). The outermost layer of thermal insulation material should be wrapped with waterproof material to prevent the thermal insulation material from absorbing water and freezing. Water supply facilities in the shade should be thickened and bundled.
