When we moved into our home, there were some things that we knew we wanted to upgrade. For starters, the place had some really old appliances, and we could tell they were taking up loads of energy. Instead of worrying about it, we began looking for ways to improve the house by replacing the appliances with more energy efficient versions. We found a great appliance shop that had exactly what we were looking for, and they were even having a little sale on their products. This website is completely dedicated to energy efficient items, because you never know when you will need them.
Although exchanging propane tanks is quick and easy, you also end up paying more for less fuel with each transaction. Most exchange providers don't actually fill a new tank to its functional capacity, and you end up paying for the new tank as well. If you prioritize savings over convenience, a single propane tank can last many years when properly maintained. Follow these simple steps to make sure your DOT propane tank remains safely in service for its full intended lifespan.
Storing And Transporting Tanks Safely
DOT cylindrical propane tanks are regulated by the Department of Transportation due to their portability. But transporting and storing DOT tanks means treating them with the respect they deserve. A bumped and dented tank is far more likely to develop a leak in the long run. Always transport propane securely, so the tanks don't fall over or jostle each other. Similarly, store and transport them in an upright position to avoid leaks and valve damage.
Monitoring Temperatures
Propane tanks are designed to withstand high pressures, but they still have limits. As temperatures rise and fall, the pressure the propane exerts on the tank varies as well. In winter, your tank should remain stable in all but the coldest of weather. In summer, however, it's important to store tanks in a shaded, outdoor space. Hot propane expands and pushes against the interior of the tank. A relief valve releases vapor to maintain pressure, but it can still lead to tank damage, or worse, ignition.
Refilling Tanks Before They Run Dry
Always monitor your tank and refill it before it's fully empty. When a propane tank runs completely out of fuel, the interior is exposed to moist air flowing in. That in turn can lead to rust, which eats away at the tank and poses a serious safety risk. To avoid this scenario, remember to shut the valve after using a tank, and bring it in for a refill once it's down to a pound or two of propane.
Recertifying Older DOT Tanks
Nearly all DOT tanks must be recertified to continue use once they reach a certain age. The exact expiration date depends on the type of tank in question. When it's time to recertify, you can either bring it in for inspection or exchange it for a new one. If your tank is still in good shape, however, there's no reason it can't last another decade or so before needing certification again. In this way, you can make the most of the savings offered by propane refill tanks versus exchanging them for decades to come.
