Galvanized wrought iron or galvanized steel pipe must be kept at least how many inches above ground?

• A. 2"
• B. 4"
• C. 6"
• D. 8"

Answer: (C)

Keep galvanized pipe well above ground to protect it and keep it accessible. Six inches of clearance minimizes contact with soil moisture and contaminants that can accelerate corrosion of the coating, reduces the chance of physical damage from yard work or backfill, and makes the pipe easier to inspect, measure, and repair if needed. If it sits closer to the ground, moisture and debris in the soil can attack the coating and shorten the pipe’s life, and locating or servicing the pipe becomes harder. Eight inches is more than typically required, while two or four inches would leave the pipe too close to or in the soil, so six inches is the standard minimum.
