After a propane delivery, you might check the gauge on your tank and notice it’s not at 100%. While it’s natural to think there’s been a mistake, this is actually a standard safety measure. Your tank isn’t full to the brim for a very important reason: to protect you and your home.
At P&R Propane, safety is our top priority for every customer in the Leander, TX, area. This article will explain why your propane tank is only filled to about 80% capacity and introduce some convenient services we offer to ensure you always have a safe and reliable supply of propane.
Propane is stored as a liquid under pressure, but it expands into a gas as it’s used. Like most liquids, propane expands when its temperature rises. A hot Texas summer day can cause the propane in your tank to expand significantly.
To accommodate this expansion, a professional technician will only fill your tank to about 80% of its total capacity. This leaves the remaining 20% space, known as “headspace,” for the propane vapor to safely expand without causing excessive pressure inside the tank. Overfilling a propane tank is dangerous and can lead to serious risks, including leaks or damage to the tank itself. This “80% fill rule” is a national safety code and a standard practice for all reputable propane suppliers.
So, when you see your tank gauge at 80% after a delivery, you can rest assured that our team has followed the proper safety protocols to keep your home and family safe.
