Underground Propane Tank Installation

Is the propane tank installation invasive? Will it disrupt my yard?

Excavation is usually small. A 500-gallon underground tank installation requires a 12′ x 5′ x 4.5′ deep excavation with six inches of sand at the bottom of the hole. The tank is placed in the hole and a magnesium bag is attached to the tank to prevent electrolysis (rust) from harming the tank. The tank is then backfilled with sand and landscaped.

How far can my underground propane tank be from my home?

The minimum distance between the buried tank and the home and property line is 10 feet, but the tank can be located anywhere on the property as long as the delivery truck’s 100-foot hose can reach it.

How is the propane tank piped to my home?

Underground propane piping is similar to natural gas. A trench 18″ deep is standard with sand surrounding the plastic pipe. Atop the riser at the house is a regulator that will connect to the inside piping.
