How to Detect a Propane Gas Leak

Propane leaks are flammable and, as such, can be very dangerous. At a minimum, you should conduct this leak test before the first use of the season, or if you haven’t used your propane-powered appliance in a while.

Signs that your tank may have a leak:

You Smell Gas

One of the fastest and easiest ways to identify a propane leak is by the smell. A smell like rotten eggs or skunk spray indicates you may have a propane leak. If you smell propane, contact AmeriGas immediately at 1-888-428-9779.

Usage Spikes

If you’re suddenly going through propane much faster than usual and you haven’t significantly changed your usage behavior, a leak may be the culprit.

Poor Performance

If your propane grill, space heater, or fire pit have a smaller, weaker flame than usual, or they just aren’t working the way they usually do, you may have a propane leak.

How to Conduct a Leak Check using the “Bubble Test”

Step 1 Turn the propane tank off.

Turn the tank service valve hand wheel all the way to the right, so it is firmly in the OFF position.

Step 2 Apply propane leak detector solution.

Use either special leak detector solution or, in a pinch, use thick soapy water. Apply this solution to the connections between the cylinder valve and the regulator outlet.

Step 3 Slowly open the valve and watch for bubbles.

If bubbles appear at these connection points, close the cylinder valve, tighten the connection, and repeat the process. If bubbles continue to appear, call AmeriGas immediately so we can help.

What to do if you Find a Propane Gas Leak

If you suspect a gas leak—even if you’re not sure—it’s important to take action immediately to keep yourself and your family safe.

Step 1 Turn off the cylinder valve.

As long as it’s safe to do so, turn the hand wheel clockwise completely to the right, until it’s firmly in the OFF position.

If you cannot turn the hand wheel, leave the area immediately and dial 911 or call your local fire department.

Step 2 Ensure there are no flames or sparks.

Immediately put out all smoking materials and other open flames. Do not operate lights, appliances, telephones, or cell phones. Flames or sparks from these sources can trigger an explosion or a fire.

Step 3 Get your grill and propane tank checked.

Do NOT try to use your grill again until you can determine what the problem may be. You can have a qualified service technician take a look at your grill, and either swap out your tank at a local AmeriGas retailer or contact us to see if there's a local office nearby to have your propane tank inspected.
