Baffles are required when standard sprinkler spacing is less than ________.

Baffles are essential components in sprinkler systems designed to manage water distribution effectively. When the standard spacing between sprinklers is less than 6 feet, baffles help to ensure proper coverage and prevent water overspray. They accomplish this by redirecting the water spray in a controlled manner, reducing the likelihood of uneven distribution and maximizing irrigation efficiency.

The significance of the 6-foot standard comes from common practices in sprinkler design, where tighter spacing necessitates additional measures to prevent water loss or misdirection. This requirement emphasizes the importance of maintaining adequate coverage under specific conditions, which ensures that the intended area receives sufficient watering while minimizing waste and runoff. Implementing baffles under these circumstances helps maintain the integrity of the irrigation system and fosters proper vegetation health.
