Tips for preventing freezing and keeping warm in winter water meter pipes
Winter water supply facilities are prone to frost cracking or freezing and water interruption. How to do a good job in anti freezing and heating of water meters and pipes.
For the water meter installed outdoors, cotton and linen fabric, plastic foam and other materials can be used for wrapping and insulation. In case of freezing, warm water can be used for sprinkling. The water meter installed indoors should have the kitchen, toilet, and shaded room windows closed at night to maintain room temperature. When the indoor temperature is below 0 degrees Celsius, the water can be slightly turned on at night to form a line and prevent the occurrence of freezing at night. If the water meter is not used for a long time, apply to suspend the water supply and drain the water in the meter and the pipeline behind the meter.
For outdoor water pipes, dry and warm items such as cotton can be used to tightly wrap the pipes and valves, and then wrap them with plastic bags (films). It is strictly prohibited to pour water or snow into the well outside the room. At the same time, residents who use solar water heaters should promptly empty the water in the solar water heater to avoid the occurrence of solar water pipe bursts.
Once the water meter and water pipe are found to be frozen, they should be wrapped in a hot towel first, then poured with warm water to thaw and freeze. Then, twist the water and slowly sprinkle warm water along the water pipe to thaw it. If no water flows out even after pouring to the water meter, it indicates that the water meter has also frozen. At this time, wrap a hot towel around the water meter and sprinkle it with warm water (not exceeding 60 degrees). Do not use boiling water, fire baking or other methods to prevent thermal expansion and contraction, which may cause burst pipes and damage water facilities.
