Unlock the mysteries of manual water heater lighting: the quick and easy guide
What To Know
- Using a wire brush or a cotton swab dipped in rubbing alcohol, gently clean the pilot light orifice and the thermocouple.
- Generally, you shouldn’t need to light the pilot light manually unless it has gone out due to a power outage or a gas supply interruption.
- As long as you follow the safety precautions outlined in this guide, it is relatively safe to light a water heater pilot light manually.
When your water heater fails to provide you with warm water, one of the most common issues is that the pilot light has gone out. If you’re facing this problem, don’t panic! You can easily relight the pilot light yourself by following these step-by-step instructions.
Safety Precautions
Before you begin, it’s crucial to take the following safety precautions:
- Ensure your gas supply is turned off.
- Allow the water heater to cool down completely.
- Keep all flammable materials away from the water heater.
- Have a fire extinguisher nearby for emergencies.
Step 1: Locate the Pilot Light Assembly
Identify the access panel on the front or side of your water heater. Open it to expose the pilot light assembly.
Step 2: Turn Off the Gas Supply
Locate the gas valve near the bottom of the water heater and turn it clockwise to the “Off” position.
Step 3: Remove the Pilot Light Cap
Unscrew the cap covering the pilot light. You may need to use a wrench or pliers for this.
Step 4: Clean the Pilot Light Assembly
Using a wire brush or a cotton swab dipped in rubbing alcohol, gently clean the pilot light orifice and the thermocouple. This will remove any debris or corrosion that may prevent the pilot light from igniting.
Step 5: Reinstall the Pilot Light Cap
Once the assembly is clean, carefully screw the pilot light cap back on.
Step 6: Relight the Pilot Light
Option 1: Using a Match or Lighter
- Hold a match or lighter near the pilot light orifice.
- Turn the gas valve back on slowly while simultaneously pressing the pilot light button.
- Keep the button pressed for 20-30 seconds after the pilot light ignites to allow the thermocouple to heat up.
Option 2: Using a Piezoelectric Igniter
- Locate the piezoelectric igniter on the water heater.
- Press and release the igniter button repeatedly until the pilot light ignites.
Step 7: Adjust the Pilot Light Flame
Once the pilot light is lit, adjust the flame to a height of about 1/2 inch. You can do this by turning the gas valve adjustment screw.
Step 8: Turn On the Water Heater
Turn the gas supply valve back on completely. The water heater should start heating up within a few minutes.
Troubleshooting
If the pilot light doesn‘t stay lit, try the following:
- Check for any gas leaks using soapy water.
- Clean the thermocouple again.
- Replace the thermocouple if it’s damaged.
- Call a qualified technician if you’re still having issues.
The Bottom Line
Congratulations! You have successfully relit the pilot light on your water heater. By following these simple steps, you can save yourself the cost of calling a plumber and enjoy warm water again.
