Assessing Your Propane Line

Before connecting your gas grill, inspect your propane line to ensure it’s safe and suitable for the task:

  • Turn off and close the tank valve if you’re currently using a portable tank.
  • Disconnect the portable tank and regulator. The regulator is typically attached to the hose and the tank valve.

Connecting the Propane Line

Follow these steps to connect your gas grill to your house propane line:

  • Apply gas-rated Teflon tape or pipe joint compound to the threads of the propane line shutoff valve. This will ensure a tight, leak-free connection.
  • Attach the quick-connect fitting to the propane line shutoff valve using an adjustable wrench. Ensure the fitting is compatible with both grill and propane line.
  • Connect the grill’s hose to the quick-connect fitting. Depending on the fitting type, you may need to pull back the collar or sleeve to insert the hose fully. Release the collar or sleeve to lock the connection in place.
  • Ensure all connections are tight and secure.

Testing Your Connection


Before firing up your grill, it’s essential to check for any gas leaks:

  • Turn off all the burners on your gas grill.
  • Open the propane line shutoff valve to allows it to flow .
  • Mix a solution of water and a few drops of dish soap in a spray bottle.
  • Spray the solution onto all connections, including the quick-connect fitting, hose, and connection point.
  • Observe the connections for any bubbles forming. Bubbles indicate a gas leak.
  • If you find a leak, turn off the line shutoff valve immediately, tighten the connection, and retest. If the leak persists, consult a professional technician.
