Quick Answer
Water drums can burst or rupture if frozen, but this usually happens when water freezes unevenly in the drum, causing it to expand and exert excessive pressure.
Water Drum Freeze Risks
Frozen water drums can burst due to water expanding by approximately 9% when it freezes. This rapid expansion can exert immense pressure on the drum’s walls, potentially causing it to rupture or leak. Frozen drums may also develop hairline cracks, compromising the integrity of the container.
Assessing and Preventing Freeze Damage
Preventing water drum freeze damage involves storing them in a protected environment. Ideally, the storage location should maintain a temperature above 40°F (4°C) during the winter months. To minimize freeze risk, you can add non-toxic, freeze-proofing agents to the stored water, typically in the form of water treatment chemicals. It’s also essential to inspect your water drums regularly for signs of damage or stress cracks.
Maintenance and Repair of Frozen Drums
If you find a frozen water drum, do not attempt to thaw it in place. Remove the drum from the storage area, and let it thaw in a controlled environment. Inspect the container for any signs of damage or stress cracks after thawing. If the drum is compromised, it’s best to replace it to prevent contamination and ensure safe water storage.
