What is one major limitation of fixed spray sprinklers?

1. High water pressure requirement

2. Inability to cover wide areas

3. Limited range of motion

4. They are not suitable for use on slopes

The correct answer is: Inability to cover wide areas

Fixed spray sprinklers are primarily designed for specific areas and have a set spray radius. This means that they are optimized for watering smaller, often more uniform landscapes, such as flower beds or smaller lawns. Their design makes it challenging to efficiently cover larger or irregularly shaped areas without creating overlapping or missed spots. This limitation particularly affects the effectiveness of water distribution across varied terrain or where larger areas need coverage. In contrast, options regarding high water pressure requirements, limited range of motion, and suitability for slopes outline performance characteristics that may not universally apply to all fixed spray models but instead highlight specific design considerations or scenarios where other types of irrigation might be more effective. These factors can influence efficiency but do not define the inherent limitation of fixed spray sprinklers in terms of area coverage like the ability to cover wide areas does.
