How to Relight Pilot Light on Water Heater?

The pilot light on your water heater is a crucial component that ensures your hot water supply is working properly. If the pilot light goes out, it can leave you without hot water for bathing, cleaning, and other essential activities. In this article, we’ll guide you through the process of relighting the pilot light on your water heater.

What is the Pilot Light?

Before we dive into the process of relighting the pilot light, it’s essential to understand what it is and its function. The pilot light is a small flame that ignites the main burner of your water heater, providing the energy needed to heat the water. The pilot light is usually located at the bottom of the water heater and is controlled by a thermostat.

Common Reasons for a Pilot Light to Go Out

There are several reasons why the pilot light on your water heater might go out, including:

• Drafts: If there are drafts in your home, it can extinguish the pilot light.
• Faulty thermocouple: The thermocouple is a safety device that ensures the pilot light remains lit when the burner is not in use. If it’s faulty, the pilot light may not stay lit.
• Improperly adjusted pilot light: If the pilot light is not adjusted correctly, it can cause it to go out.
• Dirty or clogged pilot light: If the pilot light is dirty or clogged, it can cause it to go out.
• Low gas supply: If the gas supply to your water heater is low, it can cause the pilot light to go out.

How to Relight the Pilot Light

Relighting the pilot light is a relatively simple process that requires some basic tools and caution. Here’s a step-by-step guide to help you relight the pilot light:

Step 1: Turn off the Gas Supply

Important: Before attempting to relight the pilot light, make sure to turn off the gas supply to your water heater. This is a safety precaution to prevent any accidental gas leaks.

• Locate the gas shut-off valve, usually located near the water heater or at the gas line.
• Turn the valve clockwise to shut off the gas supply.

Step 2: Check the Thermocouple

• Check the thermocouple for any blockages or damage. If it’s faulty, you may need to replace it.
• Clean the thermocouple if it’s dirty or clogged.

Step 3: Remove the Pilot Light Cover

• Locate the pilot light cover, usually a small metal or plastic cover, and remove it.
• Be careful not to touch any of the internal components.

Step 4: Relight the Pilot Light

• Hold a lit match or lighter near the pilot light opening. Note: Make sure the match or lighter is not too close to the pilot light opening, as it can cause a gas leak.
• Once the pilot light is lit, release the match or lighter and hold the pilot light button (usually a small knob or button) for 30 seconds to ensure the flame is stable.
• If the pilot light goes out again, you may need to adjust the pilot light orifice or clean the pilot light assembly.

Step 5: Adjust the Pilot Light

• If the pilot light is not adjusting properly, you may need to adjust the pilot light orifice. This is usually done by turning a small screw or adjusting a nut.
• Consult your water heater’s user manual or contact a professional if you’re unsure how to adjust the pilot light orifice.

Step 6: Turn On the Gas Supply

• Once the pilot light is relit and stable, turn the gas shut-off valve counterclockwise to restore the gas supply.

Tips and Precautions

• Be patient: Relighting the pilot light may take some time and patience, so don’t rush the process.
• Use caution: When working with gas, it’s essential to exercise caution to prevent accidents and ensure your safety.
• Consult a professional: If you’re unsure about relighting the pilot light or if the problem persists, consult a professional plumber or HVAC technician.

Conclusion

Relighting the pilot light on your water heater is a relatively simple process that requires some basic tools and caution. By following the steps outlined above, you should be able to relight the pilot light and restore your hot water supply. Remember to always turn off the gas supply before attempting to relight the pilot light, and consult a professional if you’re unsure about the process.
