Your propane tank is the heartbeat of your home’s heating system — quietly working behind the scenes to keep your family warm, your showers hot, and your appliances running smoothly. But like any piece of equipment, propane tanks don’t last forever. Over time, wear and tear, corrosion, or outdated technology can make replacement the safer and smarter choice.

At Tankfarm, we believe in helping homeowners make confident, informed decisions about their propane systems. That’s why we’ve outlined the five most common signs it’s time to replace your propane tank — and how to upgrade safely, affordably, and without the headaches.

1. Your Tank Is Showing Visible Rust or Corrosion

Propane tanks are built to be tough, but exposure to the elements can take a toll. If you notice rust spots, peeling paint, or corrosion on your tank’s surface, it’s time to take a closer look. Rust not only weakens the metal but can also hide small leaks or cracks that compromise safety.

Surface rust may not always be a dealbreaker, but if it’s widespread or deep enough to cause pitting, replacement is likely the best long-term solution. Especially in New England, where snow, ice, and salt exposure are common, rust can progress faster than you think.

If you’re unsure whether your tank’s condition is cause for concern, Tankfarm technicians can perform a comprehensive safety inspection to determine whether repair or replacement is your safest option.

2. The Tank Is More Than 15–20 Years Old

Most above-ground propane tanks are designed to last about 15 to 20 years, depending on size, material, and environmental conditions. Underground tanks may last slightly longer, but they’re also more susceptible to moisture-related corrosion.

If your propane tank has been in service for two decades or more, it’s smart to plan ahead for replacement — before a problem arises. Older tanks may no longer meet current safety standards, and internal components like valves and regulators can wear out over time.

Tankfarm offers modern, technology-enabled propane systems that include remote monitoring. These monitors help ensure you’ll never run out of fuel unexpectedly and give our logistics team real-time data to keep your system running at peak performance.

3. You Notice Frequent Delivery or Pressure Issues

A properly functioning propane tank should maintain consistent pressure and reliable delivery to your home. If you’ve noticed uneven heating, weak appliance flames, or more frequent refill alerts, your tank could be struggling to maintain optimal performance.

Sometimes these issues stem from temperature fluctuations or regulator malfunctions — but in older tanks, internal rust or valve deterioration can restrict propane flow. Over time, that leads to inefficiency and, in worst-case scenarios, a complete shutdown of your system.

Replacing your tank doesn’t just restore reliability — it can also improve efficiency and lower fuel costs. Tankfarm’s smart monitoring technology automatically tracks your usage and sends refill signals when your tank reaches 30%, optimizing deliveries and reducing waste.

4. There’s Evidence of Leaks or Unusual Odors

Propane has a distinct odor (similar to rotten eggs) that’s added intentionally as a safety measure. If you ever smell propane near your tank, lines, or appliances, take it seriously. Turn off your gas supply, evacuate the area, and call a professional immediately.

Leaks can occur from damaged valves, worn seals, or corrosion at connection points. In many cases, older tanks or outdated fittings are to blame. Once leaks appear, replacement is often the only safe solution — temporary fixes may not hold up under pressure.

Tankfarm’s technicians are trained to diagnose and resolve propane leaks quickly, and we can help you transition to a new tank system that meets all current safety codes, ensuring your home and family stay protected year-round.

5. Your Energy Needs Have Outgrown Your Current Tank

If you’ve recently added new propane-powered appliances, expanded your home, or installed a pool heater or generator, your current tank size might no longer fit your household’s energy demands. Running too small of a tank can lead to frequent deliveries, inconsistent heating, or system strain.

Upgrading to a larger tank — or adding an additional one — allows for better efficiency, fewer deliveries, and more predictable pricing. At Tankfarm, we assess your total energy consumption to help determine the right tank size and installation strategy for your property.

When you replace an outdated system, it’s also the perfect opportunity to upgrade your entire propane setup with smart monitoring for total convenience. You’ll be able to track fuel levels, schedule deliveries automatically, and rest easy knowing your system is optimized for both comfort and cost.
