When purchasing a centre pivot, growers likely have expectations for the lifespan of the equipment. Some centre pivot pipelines are still dependable after 25 to 30 years of use; other pipelines show leaks after only 7 to 10 years. Corrosion is a key factor in the breakdown of pivot pipelines, and can cause leaks, cracks, and even structural damage. While many people may think this has only to do with the quality of the machine equipment, the life expectancy of centre pivot pipelines is determined by the number of hours of operation (rather than years) and the water quality running through the pipeline. Since not all water quality is the same in different regions, or even in neighbouring regions, not every centre pivot will withstand the same amount of hours of operation.
