What is the reason for the leak of the newly purchased water cup?

1.The production quality of the water cup causes poor sealing. Such water cups should be returned as soon as possible, if it is very serious, it is recommended to return directly. The water cup sealing process is the most basic requirement for the qualification of the cup. If a brand's water cup has serious leakage without being used, it means that the brand management is not strict and the overall quality control is relatively poor.

2.The sealing ring of the lid of the water cup is not installed properly. This situation may be caused by vibration during transportation, or due to large temperature changes. In this case, just soak the gasket in hot water for 3 minutes, then install it again, and then tighten and unscrew it several times.

3.Damage or deformation caused during transportation. This situation occurs when the water cup is impacted by a relatively large external force during transportation, causing physical changes in the water cup.
