Warm tips for freezing and cracking of waterproof pipes in winter?

1. Dress and wear hats: For water facilities such as outdoor water pipes, water meters, faucets, etc., cotton and linen fabrics and plastic foam can be used for wrapping and insulation.

2. Close the windows to prevent cold: When the weather is cold, especially at night, close the windows of the balcony, kitchen, bathroom and all north-facing rooms to ensure that the indoor temperature is above zero.

3. Dripping water into lines: In severe cold weather, if the temperature is below -5℃, you can slightly turn on the faucet at night to make the water flow into lines to ensure the flow of tap water in the pipe to prevent freezing at night.

4. Water security: Be prepared to store water at night, preferably hot water, to avoid inconvenience to your life the next day.

Notes:

For floor heating pipes, such as PE-RT, PB, oxygen barrier pipes or Dalda pipes, After the pressure test, use a small air compressor to blow out and dry the water in the pipe in time.

Outdoor pipes: When directly buried, they should be buried deeper than the freezing line. Pipes that need to be insulated must be insulated.

For PP-R pipes that transport hot water, when the ambient temperature is low, the hot water in the pipe transfers heat outward, causing the temperature of the hot water in the pipe to drop and increasing the heat loss of the pipe. Therefore, insulation measures should be taken when the temperature is low. Generally, insulation materials are added to PP-R pipes, such as rubber-plastic insulation pipes, high-foaming PE closed-cell insulation pipes, rigid polyurethane plastic pipes, and on-site spraying of polyurethane polyester foaming agents, etc.
