Is there the best plan to prevent outdoor water pipes from freezing?

1, wear a hat

In places with low temperatures, especially in the north, when the temperature reaches zero degrees Celsius, water begins to freeze. Therefore, water equipment such as water pipes should be wrapped in cotton and linen fabrics, plastics, foam and other items to keep warm. These can start with home improvement, and the water pipes can be beautifully wrapped. Some thoughtful owners also graffiti on indoor water pipes, which can not only beautify the indoor visual effect, but also do a good job in anti-freezing measures of water pipes.

2, improve the indoor temperature

When it is cold in winter, the indoor temperature is also relatively low. If you don't close the balcony, kitchen, bathroom and all the doors and windows facing north at night, the indoor temperature will be lower, and even the indoor water pipes will freeze, so when decorating your home, you should think about how to improve the indoor temperature in winter. For example, the curtains facing north are thicker, which can keep the room warm to some extent. It's cold, so you have to close the doors and windows and close the curtains at night.

3. Drop antifreeze

Generally speaking, it is difficult for water to freeze if it keeps flowing, so there is a small way to turn on the tap at night and let the water keep flowing to avoid freezing the water pipe. Although this method can prevent water pipes from freezing, it has the defect of wasting water after all.

4. Drain the remaining water in the water pipe.

In view of the waste caused by the above methods, I will provide you with another method, that is, pull down the sluice at home before going to bed in the cold winter night, and then turn on the tap to drain the water in the water pipe, so that there is no water in the water pipe and it will not freeze, but keep the sluice warm to prevent it from freezing and not opening the next day.

5, water pipe heat transfer

One of the widely used methods in solar water heaters is electric heat tracing insulation bag. This method is also feasible for the insulation and heating of water pipes, but it is more expensive. You can try it if you have good economic conditions at home.

Extended data:

The emptying valve is a kind of pipeline emptying device, which is understood and accepted by people. It is mainly used in solar water heaters to solve the freezing and blocking of water pipes caused by cold weather. The emptying valve can be divided into: solar pipeline emptying valve, solar water heater emptying valve, steam emptying valve, manual emptying valve, automatic emptying valve, etc.

Evacuation valve function

1. pipeline anti-freezing: this product can drain the water in the water pipe manually or automatically. Because there is no water in the pipeline, it can achieve the purpose of waterless antifreeze. It can be used for antifreeze of solar water pipes and tap water supply.

2. Water is hot when it comes out: because there is no water in the upper and lower pipes, as the application of solar energy, the history of putting cold water first and then hot water is changed, and hot water flows down directly. As an antifreeze for tap water, it changed the freezing situation of outdoor faucet. You can use tap water all year round without worry.
