In order to do a good job in the winter anti-freezing and warmth work of water supply facilities and ensure the normal use of water during low temperature and severe cold weather, we will introduce the common sense of anti-freezing and warmth of water supply facilities. 1. Anti-freezing and warmth knowledge of water supply facilities.
1. Try to avoid direct exposure to outdoor air in the tap water pipe, and if possible, it must be buried in the ground and into the room. For outdoor exposed water supply pipes, valves, and faucets, special insulation materials or straw, cotton and linen fabrics, plastic foam, etc. can be thickened and tightened to prevent them from being frozen. The connection parts of various pipes are the most susceptible to freezing, and it is necessary to focus on keeping warm. 2. The water pipe and water meter in the water meter box can be wrapped or plugged with straw, cotton and linen fabrics, plastic foam, yellow sand, sawdust and other materials (due to the need of meter reading, please do not wrap or bury the water meter cover), cover the water meter box cover, and keep it sealed and dry. The pipe gallery wells of high-rise residential buildings need to be blocked in advance to avoid strong cold air entering the pipe gallery passage and causing the water meter to freeze. 2. Small methods for residents' household water anti-freezing and warmth
1. Dress and wear hats: use straw, old clothes, plastic foam and other insulation materials to bandage water pipes, water meters and valves. Users who use the secondary water supply of the roof water tank should cover the water tank cover and wrap the water inlet and outlet pipes and valves of the water tank with insulation materials.
2. Dripping into a line: When the temperature drops below zero, you can slightly unscrew the faucet to the line flow at night to ensure the flow of tap water in the pipe to prevent freezing at night. Dripping water can be reconnected with a suitable container to save water. 3. Emptying and crack prevention: close the valve in front of the meter before going to bed at night, and open the faucet at the lowest place to empty the stagnant water in the pipeIf you are using a solar water heater, drain the water in the water pipe of your solar water heater before freezing weather comesIf the water meter is not used for a long time, you can also close the valve in front of the meter, open the faucet at the lowest point to empty the stagnant water in the pipe, and prevent freezing or leakage. 4. Close doors and windows: When the weather is cold, especially at night, the windows of the balcony, kitchen, bathroom and all north-facing rooms should be closed to ensure that the indoor temperature is above zero degrees Celsius. 5. Store water in advance: If necessary, store some domestic water in advance for basic needs.
3. Small measures to thaw
If the water supply facilities (faucets, water pipes, water meters, etc.) have been frozen and cannot be used normally, do not twist hard, do not use pliers and other tools to start hard, and do not use fire or boiling water to rinse directly, so as not to cause cracking. You can use a hair dryer to dry slowly and evenly, or wrap it in a towel or other object, and pour warm water to thaw it. Indoor pipe freezing can be thawed by raising the room temperature, such as turning on the air conditioner, etc., and gently patting at the same time until the freezing thaws. If the above methods don't work, or if your meter and main are bursting, call your water service**:82022148
