How to keep the water in the water pipe from freezing 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. Cover the top cover of the water tank on the roof, and wrap the facilities such as water inlet pipe, valve, water supply pipe, etc. exposed to the outside up and down with heat preservation 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 again to prevent the thermal insulation material from absorbing water and freezing, and the water supply facilities in the shade should be thickened and bundled.

Water will not freeze when it flows in the water pipe. In order to prevent the water pipe from freezing, users can turn on the tap before going to bed at night to let the fine water flow, and generally avoid being frozen when the water level is low in the morning.

4. Close the doors and windows at night to ensure that 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.
