What does P.O.C. Codes refer to in this context?

• A. P.O.C. Codes
• B. Pipe Sizing
• C. Velocity
• D. Friction Factor

Answer: (A)

POC codes refer to the labeling used for the Point of Connection on irrigation project documents. They identify where the irrigation system ties into the water supply and carry the requirements set by local codes or the utility, such as backflow protection, valve location, and service details. This coding helps plan readers and installers know exactly what connection is being referenced and what standards apply, ensuring the hook-up meets regulations. The other terms—pipe sizing, velocity, and friction factor—describe hydraulic properties and design calculations, not the documentation or identification system for the connection point.
