Kickback in a water pipeline is typically caused by a sudden change in the flow of water, such as when a valve is closed too quickly or when a pump suddenly shuts off. This change in flow creates a pressure surge that travels back through the pipeline, causing the water to kick back.

To prevent kickback, it is important to use proper surge protection devices and control the flow of water in a gradual and controlled manner. **
