Water pipe antifreeze method in winter

Low temperature not only affects people's travel, but also has a considerable impact on the normal drinking water of household tap water. When the temperature drops to a certain level, water supply facilities such as water pipes and meters may freeze and crack. IFAN reminds everyone to do a good job of antifreeze and heat preservation for indoor and outdoor water pipes, water meters and faucets. According to the actual situation, the following measures can be taken:

1. Antifreeze measures:

——Clothes and hats: Water pipes, water meters, faucets and other water facilities exposed outdoors can be wrapped and kept warm with cotton fabric and plastic foam.

——Close windows to prevent cold: In cold weather, especially at night, close the windows of balconies, kitchens, bathrooms and all rooms facing north to ensure that the indoor temperature is above zero.

——Drip water into a line: In severe cold weather, if the temperature is below -3°C, you can gently turn on the faucet at night to make the water flow into a line, so as to ensure the running water in the pipe and prevent freezing at night.

-Water protection: In order to avoid inconvenience in the next day's life, prepare for water storage at night.

- Close the valve to prevent leakage: When you are not staying or no one lives for a long time, you can close the water valve in front of the meter head to drain the remaining water in the pipeline. If you go out for more than two days, it is best to close the tap water valve and then drain the pipeline Empty the remaining water.

2. The most likely time for water level gauges and pipelines to freeze and crack:

In the low temperature weather at midnight, because most residents do not use water at this time, the water in the water meter and pipes is in a static state, and midnight is the time of the day when the temperature is the lowest, and the water is most likely to freeze at this time.

3. The water level gauge and pipeline are the most prone to cracking.

Outdoor pipes and water meters and other water facilities without insulation measures; water meters and pipes are close to the west and north walls of the building; water meter well covers (doors) or meter box covers are missing or not covered (closed); On the windows of vents and doors, but the doors and windows are not closed properly; the pipes and water meters of the pipe wells of high-rise buildings, for example, each floor of the pipe well is not separated, and the internal cold air flows up and down.

4. What to do after freezing?

For water facilities that have been frozen, first wrap the faucet with a hot towel, then pour warm water, then unscrew the faucet, and slowly pour warm water along the faucet. If the water meter is poured on the water meter and there is still no water, it means that the water meter has been frozen. At this time, wrap the water meter with a hot towel and pour warm water (below 30 degrees Celsius) to thaw the water meter. Do not shower with boiling water or fire, so as not to damage the water meter.
