Gas Leak

What's in This Article?

What to do if you have a leaking propane tank and how to check for leaks.



Gas leak symptoms often include the following:

  • You smell propane gas
  • Your propane tank appears to be using more fuel than expected


The connection points between the propane tank and the grill are not secure.

What to Do if You Think You Have a Gas Leak

  1. Shut off gas to the appliance.
  2. Extinguish any open flame.
  3. Open the grill lid.
  4. If the odor continues, keep away from the appliance and immediately call your gas supplier or your fire department.
  5. Check for a gas leak.

How to Check for Gas Leaks

Test for gas leaks under the following situations:

  • If you smell gas when the burners are lit or when not in use
  • Attaching the regulator hose to a new propane tank
  • When servicing the grill
  • Attaching a new propane tank or reattaching the regulator hose to an existing one
  • After a period of non-use.

Safety Precautions:

  • Always leak test your appliance outdoors in a well-ventilated area.
  • Never smoke or permit sources of ignition in the area while doing a leak test.
  • Do not use a flame (i.e. a lighted match) to test for leaks. 

Tools Needed:

  • Spray bottle or dish
  • Soap & water solution (1 part liquid soap, 1 part water)
  • A brush or rag (something to apply the soapy water)

How to Test

  1. Check for damage on the propane line.

  2. Check the regulator hose for signs of abrasions, cracks, or leaks. Replace if worn.
  3. Make sure all the control knobs are in the OFF (o)position.
  4. If using an LP tank, turn the tank valve knob counterclockwise one turn to open.
  5. Apply the soap solution on joints of the gas delivery system. This includes all valves, pipe connections, joints, lines and every point from the gas source to the burners.
  6. Bubbles appearing in the soap solution and/or a faint gas smell (typically, gas has a rotten egg smell) indicates that a leak is present. Do not attempt to ignite the Flat Top Grill.
    • Do not use the appliance until the leak is corrected.
    • The following diagram is intended to show what a leaking connection would look like. These two locations are not the only points to check, nor the only potential areas for a gas leak to be present.

How to Fix a Gas Leak

If you determine you do have a gas leak and have found its location using the steps above:

IMPORTANT: If the tank valve is damaged, do NOT attempt to repair the tank valve. The tank must be discarded at a proper LP tank location and then replaced. Call an authorized gas appliance service technician or an LP gas dealer.

  1. If the leak is on the hose itself, replace the regulator hose.
  2. If the leak is on a connection point:
    1. Close the propane tank.
    2. Disconnect the regulator hose at the leaking connection point. 
    3. Clean both the male and the female ends of the connection point.
    4. Remove any old sealant or tape in the event of a flared connection
    5. Tighten the loose joint and/or resealing with thread sealant or Teflon™ tape
    6. Do another leak test.
  3. If the leak continues, contact Customer Support to replace the faulty part.
