At what height should relief valves be installed above ground?

Relief valves should typically be installed at a height of 12 inches above the ground. This height ensures that the valve is above potential flooding or standing water, allowing for proper drainage and minimizing the risk of corrosion or damage from the elements. Additionally, positioning the valve at this height facilitates easier access for maintenance and inspection while ensuring that any discharge from the valve falls safely away from personnel and equipment.

While different environments or codes may dictate various installation heights, 12 inches is widely accepted as a standard practice in many utility and maintenance contexts. This positioning helps to balance functionality with safety considerations, making it a preferred choice among regulators and industry standards.
