If a pipe size is missing on the irrigation plan, what should the technician do?

• A. Call the licensed irrigator
• B. Guess size
• C. Modify plan
• D. Install new pipe

Answer: (A)

Accurate pipe sizing on a plan is essential because it directly affects flow, pressure, and the ability to properly irrigate each zone. When a pipe size is missing, the technician should verify it with the person who prepared the plan—the licensed irrigator. They have the authority and the correct data to confirm the size or provide updated documentation, ensuring the design meets requirements and codes. Guessing the size is unsafe because it can lead to wrong pressure and flow calculations, resulting in poor irrigation performance or system damage. Modifying the plan without verified sizing or installing pipe without confirmation would also be inappropriate, as these actions bypass proper design and approval.
