1. Fire-fighting steel-plastic composite pipes for water pipes

The water pipes commonly used in our homes are PPR water pipes and PVC pipes. The sudden drop in temperature will have certain impacts on the water pipes. For water pipes, water meters, faucets and other water facilities that are exposed to the outdoors, warm materials such as old clothes, cotton wool, sponges, etc. can be bundled, and a layer of waterproof material such as plastic cloth can be wrapped around the thermal insulation materials to prevent them from being frozen.

Two, close the window to prevent cold

When the cold wave comes, usually especially at night, close the windows of the balcony, kitchen, bathroom and all north-facing rooms to ensure the indoor temperature and prevent the cold air from affecting the water facilities.

Three, dripping water to prevent freezing and keep it flowing

In the severe winter, especially when the temperature drops below zero, you can turn on the faucet slightly at night to make the water flow into a line, and catch the dripping water with a basin or bucket. In this way, it is possible to ensure the flow of tap water in the pipe and prevent freezing at night.

Four, timely emptying and antifreeze

In addition to dripping water to prevent freezing, you can also take emptying to prevent freezing. Before going to bed at night or when going out for a long time, you can close the water gate at home and turn on the faucet to drain the water out of the water pipe, so that there is no water in the PPR pipe and it will not freeze. In addition, the water pipe of the solar water heater should also be installed with a vertical anti-freezing drainage device for emptying and anti-freezing.

5. Do not boil the water to scorch the frozen faucet or water pipe

Sprinkle the PPR water pipe to defrost the water pipe, or you can also use a hair dryer to blow it. If there is no water flowing out to the water meter, it means that the water meter is also frozen. At this time, wrap the water meter with a hot towel and sprinkle it with warm water not higher than 30 degrees to defrost the water meter.
