What dealers handle
For leased tanks, the dealer is responsible for tank condition and most fitting maintenance. Standard inclusions:
- Annual inspection (visual check of tank, fittings, regulator)
- Regulator replacement when end-of-life (typically every 15–25 years)
- Leak testing required by NFPA 58 after any service interruption
- Replacement of damaged or out-of-spec components
- Cathodic anode check on underground tanks every ~3 years
What customer-owned tank owners handle
If you own your tank, the same maintenance is your responsibility — typically performed by a licensed propane technician. Regulator replacement is the most material periodic cost ($200–$500 every 15–25 years). Most independent service technicians charge $75–$200 per service call.
What you can do as the homeowner
Three monthly checks that catch most issues before they become emergencies:
- Visual inspection of the tank dome, regulator and visible piping. Look for rust, frost (indicating a regulator leak), dead vegetation near buried lines, or unusual moisture.
- Gauge check — read the dial gauge to confirm fuel level matches expectations.
- Smell check in the vicinity of the tank. Faint propane smell near the tank is a flag — call your dealer.
Painting and rust
Aboveground tanks need periodic paint touch-up — every 5–10 years in most climates, more often in coastal salt-air environments. Use light colours (white, off-white, light grey) to minimise heat absorption. Never paint the regulator, valves or fittings.
FAQ
How often should a propane tank be inspected?
Annually by your dealer or a licensed propane technician. Most dealers include this in service plans for leased tanks. Customer-owned tanks: arrange an annual visit at $75–$200 per service call.
Do propane tanks expire?
ASME tanks do not expire and don't require recertification. DOT cylinders (portable 20 lb / 100 lb tanks) require recertification 12 years after manufacture, then every 5 or 7 years depending on the recertification method.
