Why Isn’t My Propane Tank 100% Full After Delivery?

Written on: February 12, 2024

Get To Know The 80/20 Rule

propane tank Denton, NC Have you ever noticed that your propane tank is never 100% full after a delivery. That’s by design. Why don’t we completely fill your propane tank? Physics. Propane is a liquid. When liquids warm up, they expand and take up more space. Propane in particular expands a lot and quickly. In fact, it expands about 17 times the volume water does given a set temperature increase. For this reason, our technicians leave extra space so the propane can safely expand. For above-ground tanks, that means filling the tank to about 80% capacity. Underground tanks are filled slightly more because by virtue of being underground they’re insulated against big temperature swings. So now you know why your propane tank isn’t 100% full after delivery.

As a general rule, you don’t want your tank’s propane level to go below 20%. Just keep in mind that your gauge isn’t fool-proof or perfectly accurate, so best not to push your luck delaying a propane delivery. Order more propane for your propane tank before it gets close to 20%.

Reading Your Propane Gauge

Do you know how to tell how much propane you have in your tank? Do you know what we mean by 20%?

The simplest way to tell how much propane you have left is to check your tank’s gauge. Some tanks come with a pre-installed gauge. You can also buy a gauge and install it yourself.

Remember, as a general rule of thumb, you don’t want to let your tank’s level fall below 20%. Here’s how to find your tank and read its gauge so you’ll always know how much propane you have, and you can avoid an empty tank.

Step 1: Locate your tank. If you have an above-ground tank for your Denton, NC home, it’s pretty hard to miss. You probably already know where it is, but if not, just take a walk around your home. You’ll find it. Underground tanks can be trickier to find. Look for a small plastic dome. It will be a minimum of 10 feet away from your home and any other structure. Underneath the dome you’ll find the gauge for your tank. Now you’re ready to read it.

Step 2: Read the gauge. Most above ground and underground propane tanks use a float gauge system. Don’t worry, these types of gauges aren’t difficult to read. When you check the gauge, you’ll see a number that number represents a percentage. For example, if the dial reads 20, you have approximately 20% of a tank left of propane. If you know your tank’s capacity, you can calculate the number of gallons than percentage represents. If you’re really on top of things, you know your weekly propane usage and can calculate how long your current supply will last. Just remember, you never want your tank to completely run out of propane! In fact, you always want your propane tank to be at least 20% full.
