ASME CertifiedShips Empty
This tank ships empty. You can add a first fill of propane below. If you do, the tank is filled only after it has been installed and has passed its leak check - a licensed local propane supplier we arrange makes the fill, usually a few days to two weeks after installation. How refueling works

The 500 Gallon UG Propane Tank is a new ASME vessel made for burial, measuring 9 ft 10 in long by 37.42 in wide by 4 ft 6 1/2 in high and rated at 250 psig.
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.
400 gallons is 80% of this tank's 500-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
- Fill valve
- Double-check filler valve - the connection the delivery truck fills through. 250 gallons and up take the 1-3/4 inch ACME bulk-fill connection.
- 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.
Home delivery - shipped by freight to your address
- Liftgate service is included on residential freight deliveries.
- Delivery is curbside: the driver brings it to the vehicle access point, not to the pad. Moving and setting the tank is installation work.
- The carrier calls the number on your order to book a delivery window, and someone must be there to receive it.

About the 500 Gallon UG Propane Tank - ASME
The 500 Gallon UG Propane Tank is a new ASME vessel made for burial, measuring 9 ft 10 in long by 37.42 in wide by 4 ft 6 1/2 in high and rated at 250 psig. It suits a home or commercial building that wants a full-size propane supply for heat, hot water, a pool heater or a generator with only the dome showing. The tank dome and lid are included, and underground installation with excavation can be added for $2,400.
Key specifications
- Dimensions (l x w x d): 9 ft 10 in x 37.42 in x 4 ft 6 1/2 in
- Built to ASME Section VIII, Division 1; complies with NFPA 58
- Pressure rating: 250 psig, rated from -20°F
- Finish: red oxide TGIC powder coating, ready to bury
- Black polyethylene shroud and galvanized steel dome
- Anode bolt on the riser for the cathodic protection connection
- Duplicate stainless steel nameplate and dual lifting lugs
- Vacuum purged; can be evacuated to a full (14.7 psi) vacuum
- #72 liquid level outage valve orifice
Buried or above ground at 500 gallons
The tank is the same size either way; the difference is the installation. Burial means excavation and a higher installed price, but nothing stands in the yard and the vessel is shielded from sun and storms. A pad installation is quicker and costs less to put in. If appearance is not the deciding factor, compare the 500 gallon above ground tank.
Common questions
What is the anode bolt for? It gives the installer a secure point to connect the anode that protects the buried steel from corrosion.
Why is it vacuum purged? Air has been drawn out of the vessel at the factory, so it is ready for its first fill once it has been set and connected.
Is the dome included? Yes, the tank comes with its dome and lid.
A 500 gallon underground propane tank for whole-home heating
500 gallons is the standard size for heating a home on propane - roughly 400 usable gallons at the 80% fill line, enough to carry a 2,500 to 4,500 sq ft house through a heating season alongside hot water, a range and a generator. Buried, it does all of that from under the lawn, which is why it is the size most homeowners choose when the tank would otherwise sit somewhere they have to look at it every day.
Built to be buried
This is a vessel specified for below-grade service, not an above ground tank put in a hole: protective coating for soil contact, an anode for cathodic protection, and a shroud and dome keeping the valves, regulator and gauge accessible and weather-protected at ground level. Filling and reading the gauge happen at the dome exactly as they would on an above ground tank.
Installation, delivery and first fill
Installation can be added at checkout at a fixed price with the excavation included, carried out by a licensed installer we arrange locally - so the number you pay is the number you were quoted. Delivery is by freight to any address in the 48 contiguous states at our flat rate. The tank ships empty and is charged on site by a licensed propane supplier after the installer has set and tested it.
