The top of a post indicator valve must be located above final grade within which inches range?

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

Answer: (C)

The main point is making the valve easy to see and reach while staying protected in the landscape. A post indicator valve must sit high enough so its indicator can be read without kneeling or bending, and low enough that maintenance tools can reach it and the valve can be operated without climbing. The 32–40 inch range provides a practical balance: it places the top well above grade for visibility and snow or mulch clearance, yet keeps it within comfortable reach for routine checks and operation. If it were much lower, debris or plant growth could obscure it; if much higher, reaching and servicing becomes awkward or unsafe. So the top should be 32 to 40 inches above final grade.
