Step 1 — Site survey
Installer visits the property to confirm the planned tank location meets NFPA 58 setback rules, measures the yard-line distance to the house, identifies any soil or access challenges, and verifies the regulator and connection plan. Typically takes 30–60 minutes.
Step 2 — Permitting
Installer files for state and/or local permits — typically state fire marshal or local building department. Permit issuance takes 1–10 business days depending on jurisdiction. Cost: $50–$400.
Step 3 — Excavation (underground only)
For underground tanks: excavation crew digs a hole sized for the tank plus sand bedding. Bottom is levelled and bedded with clean sand to support the tank evenly and prevent stress. Cathodic protection (sacrificial anode) is installed before backfill.
Step 4 — Tank placement
Aboveground: tank lifted onto its concrete pad or metal cradle, anchored if required by local code. Underground: tank lowered into the prepared hole, anchored to prevent buoyant rise from groundwater.
Step 5 — Regulator and connections
First-stage regulator installed on the tank, dropping pressure to ~10 psi. Yard line (typically PE tubing) trenched from tank to house at 18–24 inch depth, with tracer wire above. Second-stage regulator installed at the house. Connections to home piping are made and shut-off valves placed.
Step 6 — Pressure test and inspection
System pressurised above operating pressure and held to verify no leaks. Inspection by state or local authority confirms compliance with NFPA 58 setback rules, proper installation, pressure-test results. Inspection approval is required before first fill.
Step 7 — First fill
Dealer delivers the first load of propane, typically the same day or next day after inspection passes. Driver performs final leak verification and you're operational.
FAQ
How long does propane tank installation take?
1–3 days total for aboveground residential installations including permits and inspection. 3–7 days for underground installations due to excavation and additional inspection. Permit wait times can extend either by 1–10 days.
Do I need to be home during installation?
For most of the work, no — installers typically don't need access to the home. For the second-stage regulator installation at the house and any indoor piping work, yes.
