ALWAYS test your liquid propane tank each time it is exchanged or refilled, seasonally and any time your grill has gone unused for a lengthy period of time.
Testing your grill for a gas leak may sound dangerous, but the reality is that it’s much easier than you may think. In fact, all you need are a few minutes, a little dish soap and some water.
Testing Your Grill for a Gas Leak
Make sure all grill burner knobs are in the OFF position and the propane tank is turned to OFF before testing. Testing should always be done outdoors, in a well-ventilated area and away from ignition sources such as gas-fired or electrical appliances, open flames or sparks.
Mix a 50/50 solution of water and liquid dish detergent. Put the mix in a dish or spray bottle.
Then turn the propane tank valve ON to pressurize your system.
Now you’re ready to test for leaks. Using a spray bottle, clean sponge or paintbrush, spray or brush the soapy solution onto the gas valve, the hose and the regulator. Stand back and visually inspect all the places where the solution was applied. Soap bubbles will instantly form and grow if there’s a gas leak in any of the components. No bubbles means no leak.
If bubbles DO form or you smell gas, turn the propane tank off immediately. If bubbles appear on the propane tank itself, do not use or move the LP cylinder. Contact an LP gas supplier or your fire department.
Consult your grill manual for how to replace or repair damaged grill components.
