Description
120 Gallon Underground ASME Propane Tank
Sometimes you need propane storage that’s completely invisible — even when space is extremely limited. This 120 gallon underground ASME propane tank buries compactly beneath your yard, providing out-of-sight propane storage for applications where above ground tanks aren’t acceptable or practical.
Specifications
- 120 gallon water capacity — approximately 96 gallons usable propane
- ASME certified specifically for below ground installation
- Steel construction with corrosion-resistant exterior coating
- Dome assembly with standard valves, gauge, and relief device
- Compact size requires minimal excavation compared to larger underground tanks
- Compatible with anode bag cathodic protection systems
Compact Underground Storage
Not every property needs — or has room for — a 500 or 1000 gallon underground propane tank. This 120 gallon below ground tank provides a practical smaller option for seasonal homes, guest houses, pool house heating systems, and small primary residences in mild climates. The small excavation footprint means less disruption to your yard and lower installation costs.
Where This Tank Shines
This underground propane tank is particularly popular in HOA-governed neighborhoods where visible tanks are prohibited, urban lots where setback requirements make above ground placement difficult, historical districts with appearance restrictions, and properties where aesthetics are a top priority. It gives you propane capability where other options fail.
Installation Notes
Even a compact 120 gallon underground propane tank requires proper installation: excavation, sand bedding, cathodic protection, approved backfill, and professional testing. The smaller size makes the entire process faster and less expensive compared to larger underground tanks, often completable in half a day by experienced crews.
