Post indicator valves must be set so the top of the post is within which range of inches above final grade?

• A. 12-24 inches
• B. 24-32 inches
• C. 32-40 inches
• D. 40-52 inches

Answer: (C)

Setting the post indicator valve top within 32–40 inches above final grade keeps the indicator both visible and easy to operate in everyday conditions. This height makes the post easy to spot through snow, mulch, and landscaping, while still allowing a person to reach and turn the valve without bending excessively or needing a ladder. If it’s too low (like 12–24 inches), it can be obscured by soil, debris, or mowing activity. If it’s too high (40–52 inches), operating it becomes awkward and prone to damage or tipping. The 32–40 inch range strikes a practical balance for accessibility and visibility.
