ASME CertifiedShips Empty

The 1000 Gallon Underground Propane Tank is a new ASME pressure vessel built for burial, with a 1,000 gallon water capacity, a 41 inch outside diameter and an overall length of 15 ft 11 in.

A licensed local installer we arrange excavates, beds and buries the tank, fits the dome, regulator and gas line, backfills and leak-tests every joint. The price shown is the price: the dig is included, not quoted afterwards. Save 5% on the tank and installation together.

800 gallons is 80% of this tank's 1000-gallon capacity, the legal fill limit, at $2.67 per gallon. The tank still ships empty: a licensed local propane supplier fills it after it is installed and passes its leak check - usually a few days to two weeks after installation. The pre-fill leak check and account setup are free when you order the fill with your tank. Save 5% on the tank and fill together, or 10% with professional installation as well. How refueling works

Valves & fittings included

ACME fill valve
Bulk-fill connection. This tank ships under factory vacuum seal - the first fill breaks that seal through the POL valve with methanol, and every fill after it goes through the ACME valve.
Service / vapor withdrawal valve
The vapor outlet your installer connects the first-stage regulator to.
Pressure relief valve
Required safety device. Vents to atmosphere if tank pressure rises above the set point, then reseats.
Float gauge
Dial gauge reading tank level as a percentage of capacity.
Liquid withdrawal valve
Draws liquid propane rather than vapor, for transfer and high-demand liquid service.
Vapor return valve
Returns vapor to the delivery vehicle during filling and relieves pressure back to another vessel.

Valves are factory-fitted to the vessel. The regulator, gas line and the propane itself are not included - a licensed installer connects the tank and a licensed supplier makes the first fill.

About the 1000 Gallon Underground Propane Tank (NEW)

The 1000 Gallon Underground Propane Tank is a new ASME pressure vessel built for burial, with a 1,000 gallon water capacity, a 41 inch outside diameter and an overall length of 15 ft 11 in. It suits large homes, typically buildings of 4,500 sq ft and up, as well as commercial sites and small metered communities that want central propane storage kept out of sight. Underground installation with excavation included can be added for $4,400.

What it runs

A tank this large usually supplies a whole property: central heating, water heating, a pool heater and a generator together, or commercial loads such as cooking, dry cleaning and crop drying. Shared buildings and small metered systems often run several users from a single tank of this size. Like any propane tank, it is filled to about 80% of capacity to leave room for expansion.

Key specifications

  • Water capacity: 1,000 gallons
  • Outside diameter: 41 in; overall length: 15 ft 11 in
  • Head type: hemi
  • Empty weight: 1,812 lbs
  • Rated at 250 psig; built to ASME Section VIII, Division 1, and complies with NFPA 58
  • Heavy-duty steel with a mastic coating against corrosion
  • Shipped vacuum pre-purged, under factory vacuum seal

First fill and buried versus above ground

Because the tank arrives under factory vacuum, your local propane provider makes the first fill by breaking the seal through the POL valve with methanol; after that it fills normally through the ACME valve. Once buried, only the lid shows, and it shelters the regulator, gauge and fill port from the weather. Expect the excavation to leave bare ground that you reseed or landscape afterwards. If you would rather avoid digging altogether, the 1000 gallon above ground tank is the same capacity on a pad.

Common questions

How heavy is it to move? It weighs 1,812 lbs empty, so setting it in the excavation is equipment work for the installer.

Does it come with propane? No. It ships empty, and a licensed supplier makes the first fill on site.
