Does the propane tank need to be above ground for maintenance?

Underground Propane Tank Considerations

When installing underground propane tanks, it’s essential to ensure proper installation and maintenance to prevent accidents and ensure the longevity of the tank. Typically, underground propane tanks are installed 12 inches below grade, and the surrounding soil must be compacted to prevent settling or shifting of the tank. A 12-inch clearance around the tank is also recommended to facilitate maintenance and inspections.

Access and Inspection

Having an above-ground propane tank makes it easier to perform routine maintenance tasks, such as checking the tank’s condition, inspecting the connections, and ensuring the propane supply system is functioning correctly. According to the National Fire Protection Association (NFPA) 58, propane tanks should be inspected annually by a qualified technician who can access the tank. Above-ground tanks also enable quicker and safer repair or replacement of the tank, regulator, or other components.

Safety and Regulatory Considerations

Proper installation and maintenance of underground propane tanks are critical to prevent accidents and ensure compliance with local regulations. The American Society of Mechanical Engineers (ASME) and the American Society for Testing and Materials (ASTM) provide standards for propane tank installation, inspection, and testing. Above-ground tanks can provide an added layer of safety and compliance, reducing the risk of accidents and minimizing downtime in case of a leak or other issue.
