How to Turn On a Water Heater Pilot Light
Turning on a water heater pilot light is a relatively simple process. Here’s a step-by-step guide:
Step 1: Shut Off the Gas Supply
Before attempting to relight the pilot light, make sure to shut off the gas supply to the water heater. You can do this by:
- Locating the gas shut-off valve near the water heater
- Turning the valve clockwise until it stops
- Confirming that the gas supply is shut off by checking for any hissing sounds or gas leaks
Step 2: Open the Access Panel
The access panel is usually located at the bottom of the water heater. You’ll need to remove the screws or clips to open it. This will give you access to the pilot light assembly.
Step 3: Locate the Pilot Light Assembly
The pilot light assembly is usually located at the bottom of the water heater, near the gas valve. It may be covered with a protective cap or shield. Remove any obstructions to access the pilot light.
Step 4: Remove the Pilot Light Cap
The pilot light cap is usually held in place by a screw or clip. Remove the screw or clip to access the pilot light.
Step 5: Light the Pilot Light

Step 7: Turn On the Gas Supply
With the pilot light lit, turn on the gas supply by:
- Turning the gas shut-off valve counterclockwise until it stops
- Confirming that the gas supply is turned on by checking for any hissing sounds or gas leaks
Step 8: Check the Pilot Light
Once the gas supply is turned on, check the pilot light to ensure it’s still lit and burning steadily. If the pilot light goes out, repeat the process from Step 1.
