1.Insulation cotton: The function of insulation cotton is to isolate the external temperature and protect the temperature of the water pipe. Generally, the exposed water pipes are directly closed directly, and then the water pipes can be guaranteed not to freeze. This method is the simplest, most convenient and the most economical. In fact, there are not many exposed water pipes, and a layer of protection will not increase the cost a lot. 2. Drain the water in the outdoor water pipe: The reason why the water pipe freezes is because of the water in the water pipe. Generally, the water pipe will have a valve at the position of the water meter, and the valve can be closed directly when the water is not used at night. 3. Keep the water flow: This can only be done in some places where the temperature is not very low, you can keep the water pipe dripping, and then put a bucket under it, so that the water flow will not cause freezing. Treatment after the water pipes are frozen: Once the water pipes are frozen, the water in the home will become a problem, so how can the ice be melted? Many people use hot water directly, which can melt the ice directly, but waste hot water. You can use a towel to first wrap the water pipe and then pour hot water on the towel. After one minute, wring out the water in the towel, then wrap it and water it. Generally, it will dissolve directly after three times.
