Unlike people with oil tanks, most people who use propane to heat their home and their water don’t give too much thought about the state of their propane storage tank. If your tank was included when you purchased your home, you might not even know how old it is.
Generally speaking, a propane storage tank doesn’t require too much care. They’re built with safety and durability in mind, and aboveground propane tanks are designed to withstand the elements for 30 years before they need to be replaced. Some aluminum and composite storage tanks can last even longer. Underground propane tanks last between 20 to 30 years, depending on the soil type and whether the tank was installed properly—but they can be safer, as they are less exposed to impact from storm debris and flooding.
Use these simple guidelines to help you keep your tank in good shape.
The main benefit of an underground tank is that it doesn’t detract from your home’s curb appeal. It can also be safer, depending on your home’s location. But not being able to do a visual inspection means it’s a little harder to know if there are any problems emerging.
Most new underground propane tanks have a special anticorrosion coating that helps extend their lifespan. They can last up to 30 years, depending on the soil type and whether it was installed properly. Any underground propane tank should have sacrificial anodes included in installation (typically, we recommend one bag per 500 gallons). These anodes absorb natural electric currents in the ground and water that would otherwise corrode and deteriorate your tank. In addition, you should have us perform regular maintenance and check regulators.
While an above ground tank isn’t the best-looking thing in your yard, it is easy to see if it’s showing any signs of deterioration.
Keeping an eye out for signs of corrosion on the exterior of your tank, particularly rust, is the main way to know your tank is in good shape. You should also make sure that your propane tank is always sitting level to the ground—especially if your neighborhood is prone to flooding, which can cause the ground to shift.
Whether it’s above or below ground, you should avoid letting your propane tank hit empty. It’s not just a hassle: it’s a safety issue. When your tank falls empty, the pressure change in lines can lead to damage and potential leaks. You should also make sure to get professional maintenance performed on all propane appliances so connectors can be checked regularly.
