Homeowners in Minnesota and neighboring Upper Midwest states know exactly how crucial a reliable heating system is.
When frigid winter temperatures arrive, your propane tank works hard to keep your family warm and comfortable. It also fuels everyday household essentials like your water heater, kitchen stove, and clothes dryer.
Like any piece of hardworking home equipment, propane tanks eventually wear out. Ignoring a degrading tank can lead to sudden appliance failures, safety hazards, and wasted fuel. Recognizing the early warning signs of a failing tank can help you save on energy bills and protect your property value.
Here are five key indicators that your propane tank needs a replacement.
A little bit of surface rust is normal for a tank exposed to the harsh Upper Midwest elements. However, heavy rust, deep pitting, or flaking metal are serious concerns. Deep corrosion weakens the structural integrity of the tank, making it susceptible to leaks and pressure failures. If the rust seems to be eating into the metal, you need a professional inspection right away.
Have you noticed a sudden, unexplained increase in your monthly energy costs? If your usage habits haven’t changed but you are burning through propane much faster than usual, your tank or its connecting lines might have a slow leak. Replacing a compromised tank is a smart move that will lead to a reduction in energy bills and improve your home’s overall efficiency.
Propane is naturally odorless, but manufacturers add a chemical compound that smells like rotten eggs or a skunk’s spray to help you detect leaks. If you notice this distinct odor around your yard or near the tank, act immediately. A persistent smell often points to a failing valve or a crack in the tank itself. Turn off the gas supply if it is safe to do so, evacuate the area, and contact your propane supplier.
A propane tank holds gas under high pressure. Any significant dents, bulges, or gouges on the exterior can compromise its ability to hold that pressure safely. Physical damage from falling tree branches, severe weather, or accidental bumps from lawn equipment should never be ignored.
Every propane tank has a manufacture date stamped on its collar. By law, stationary propane tanks must undergo a visual inspection and requalification process periodically, often 10 to 12 years after the manufacture date. If your tank is decades old, replacing it is usually the safest and most efficient choice.
Choosing the right propane tank doesn’t have to be overwhelming. At Lakes Gas, we bring decades of expertise to help you navigate everything from sizing and installation to understanding local regulations with ease. Our goal is to make having propane in your home simple, reliable, and stress-free.
Leasing a propane tank is a hassle-free and cost-effective solution for many homeowners, especially those who want to avoid the up-front investment of purchasing a tank. When you lease, your local Lakes Gas office handles everything. We manage the installation, regular maintenance, and required safety inspections. This means fewer worries for you and greater peace of mind, because you’ll know that everything is in compliance with strict safety standards.
Leasing eliminates the need to budget for unexpected repair costs. We ensure that the tank remains in excellent working order. Another advantage of leasing is that if you add smart home features or new propane appliances—like a range, a fireplace, or a larger water heater—we make it easy to upgrade to a bigger tank.
For those new to propane or unsure about their long-term home renovation plans, leasing offers a convenient, low-risk way to access comprehensive propane services without the commitment of ownership.
Keeping your home safe and energy-efficient is a top priority. Whether you are actively planning a home renovation or simply performing seasonal maintenance, ensuring your propane tank is in peak condition provides ultimate peace of mind.
