Where post indicator valves are used, what is the required height above final grade?

The required height for post indicator valves above final grade is specified as being between 32 to 40 inches. This height is important for ensuring that the valves are easily accessible for fire services and maintenance personnel, while still being visible for indication purposes.

The 32 to 40-inch range helps to balance accessibility with visibility without posing a risk of obstruction or damage from landscaping or other infrastructure nearby. This height ensures that operators can quickly locate and operate the valve in case of an emergency situation, which is critical for effective fire service response.

Establishing the correct height also aids in compliance with NFPA standards and local codes, which prioritize safe and efficient operation of fire protection systems. Additionally, keeping the height within this range minimizes potential hazards that could arise from valve obstructions or improper installations at incorrect elevations.
