Indicator holes are placed every how many feet?

• A. 10 feet
• B. 5 feet
• C. 15 feet
• D. 20 feet

Answer: (A)

Indicator holes are spaced at regular, fixed intervals to give you a quick, reliable way to gauge distance while laying out hose lines, setting up equipment, or tracking progress along a line. Ten-foot spacing hits a practical middle ground: it’s short enough to provide precise cues for positioning and measuring shorter distances, yet long enough to avoid clutter and keep things moving quickly in the field. If the holes were spaced closer, like every five feet, you’d have to count more markers and slow down. If they were spaced farther apart, like fifteen or twenty feet, the marked distances would be coarser and harder to estimate accurately in tight spaces or when precise placement matters.
