As the winter cold wave arrives, the risk of water meters and supply pipes freezing increases significantly, especially when temperatures stay below zero. When water temperature drops below freezing, water expands by about 10% when it freezes, exerting tremendous pressure on water meters and pipes, potentially causing them to burst or break. To prevent such issues, effective freeze protection measures are essential.
1.Why Water Meters Freeze in Winter
The primary reason water meters and pipes freeze during winter is the low temperature, especially in continuous cold weather. When water in the water meter and supply pipes remains still for a long time, it is more likely to freeze. At night, when temperatures drop below zero, particularly when it reaches -5°C or lower, exposed water meters and pipes are more susceptible to freezing. Water meters and pipes that are exposed to the outdoors, located on north-facing walls, or in areas lacking sufficient insulation are at higher risk. Additionally, water meters and pipes located near ventilation openings or areas where windows and doors are not properly closed can be affected by cold air, further increasing the likelihood of freezing.
2.Water Meter Freeze Protection Techniques and Measures
To effectively prevent water meters and pipes from freezing, the following protective measures should be taken:
(A) “Dressing Up” for Protection
A basic freeze protection measure is to “dress up” your outdoor water facilities with insulation. Use insulation materials to wrap exposed water meters and pipes, ensuring they are shielded from the cold. For outdoor water meter wells, fill them with insulating material and make sure the well covers are securely closed. In indoor areas, especially during cold weather, remember to close doors and maintain indoor temperatures to protect water meters and pipes from freezing.
(B) Close Windows to Prevent Cold Air from Entering
During cold weather, it’s crucial to close windows in rooms that contain water facilities, especially those facing north, to maintain indoor temperatures above zero and prevent pipes and water meters from freezing. For high-rise residents and property management, closing external doors, windows, and pipe maintenance doors in stairwells will also help prevent cold air from entering the building and affecting water supply facilities.
(C) Drainage and Emptying of Facilities
If you are going to be away from home for a long period, it’s important to shut off the water meter valve and drain the pipes and water heaters to prevent freezing and cracking. For secondary water supply users, ensure the water tank cover is securely in place, and tightly bundle the water pipes and valves to prevent exposure to cold air. If water meters or pipes have already frozen, avoid using open flames or boiling water to thaw them. Instead, wrap the frozen areas with warm towels and gently pour warm water over them to gradually thaw the ice.
3.What to Do if the Water Meter Freezes?
If your water meter does freeze, take immediate action to thaw it. First, wrap the frozen area of the water meter and pipes with a warm towel, then gently pour warm water over it. Avoid using open flames or boiling water as these can cause the pipes or water meter to burst. For users who frequently experience freezing in low-temperature areas, consider replacing your water meter with a freeze-resistant model. These meters have higher resistance to freezing and are a more reliable long-term solution.
4.Advantages of Freeze-Resistant Water Meters
For areas prone to freezing temperatures, installing a freeze-resistant water meter is an effective long-term solution. These meters offer several advantages:
High Freeze Resistance: Freeze-resistant water meters are rated IP68 for protection, meaning they can function even when submerged in water, making them ideal for harsh winter conditions.
Ultra-Low Power Consumption: These meters are designed with ultra-low power consumption, allowing their batteries to last for over 6 years, reducing maintenance frequency.
High-Strength Materials: These meters use high-strength mechanical components, ensuring low starting flow rates and high measurement accuracy, with an extended lifespan.
Freeze-Proof Performance: Freeze-resistant water meters have no moving parts and are protected from water, moisture, freezing, sand, and water hammer, ensuring stable performance even in extreme conditions.
No Flow Restriction Components: These meters do not contain flow restriction components, eliminating pressure loss or flow blockages, ensuring smooth and uninterrupted water supply.
Conclusion
The risk of water meters and pipes freezing during the winter months should not be underestimated. By taking appropriate freeze protection measures, such as insulating pipes, closing windows, and draining water systems, you can effectively reduce the chances of damage. If your water meter frequently freezes, consider upgrading to a freeze-resistant model for a more reliable and long-term solution. We hope everyone takes the necessary steps to ensure their water supply facilities operate smoothly throughout the winter.
