What can a flexible joint help prevent in an irrigation system?

A flexible joint in an irrigation system is primarily designed to accommodate movement and adjust to vibrations or shifts in the ground. This adaptability plays a crucial role in preventing damage to components such as sprinkler heads. When the ground settles or when temperature changes cause expansion and contraction, rigid connections can lead to stress and fractures in the irrigation system. By incorporating flexible joints, the potential for misalignment is reduced, significantly lowering the risk of breakage or damage to the sprinkler head.

While flexible joints can contribute indirectly to other concerns—such as reducing water loss and mitigating pressure buildup by allowing some flexibility in the system—this specific function highlights their importance in protecting sprinkler components directly.
