Underground Propane Tanks - common questions
- What does an underground propane tank installation involve?
- Underground tanks need a correctly sized excavation, a stable base, and cathodic protection to prevent corrosion. Installation must follow NFPA 58 and your local code, and is normally carried out by a licensed installer. Tanks ship with factory coating and anode bags fitted.
- How much do underground propane tanks cost?
- We currently stock 4 options in this range, starting at $1,950.00. Pricing is factory direct, and orders over $2,000 ship free unless the item requires freight delivery.
- How do I pay for my order?
- Place your order online and pay securely by card through Stripe. Your receipt and itemised invoice arrive by email the moment the payment goes through, and your order moves straight into processing.
- How is delivery handled?
- Smaller parts ship by parcel carrier. Tanks and cages ship by freight, and the carrier calls ahead to arrange a delivery window. Freight cost depends on your site access, so we confirm the charge and your final total before you send payment.
What to know before burying a propane tank
An underground tank keeps the yard clear and holds a steadier temperature through the seasons, which propane appliances appreciate. Only the small access dome shows above grade; the vessel itself sits in an engineered excavation on a stable base.
Burial changes the corrosion picture, which is why underground models ship with factory coating and cathodic protection. The sacrificial anode - not the tank wall - takes the electrochemical wear, and your installer verifies the anode connection at commissioning. Skipping that step is the classic underground-tank mistake, and it is entirely avoidable.
Plan the excavation before ordering: the hole needs machine access, and high water tables can call for ballasting so an empty tank cannot float. Installation must follow NFPA 58 and your local code and is a job for a licensed installer, who will also arrange the pressure test before the first fill. Like everything we sell, underground tanks ship empty and are charged on site by a licensed supplier.
