How to Start a Water Heater Pilot?

Starting a water heater pilot can seem like a daunting task, but it’s actually a relatively straightforward process. In this article, we’ll guide you through the steps to help you get your water heater up and running in no time.

What is a Water Heater Pilot?

Before we dive into the steps, let’s cover the basics. A pilot light is a small burner that ignites the main burner in your water heater. It’s responsible for maintaining a consistent temperature inside the tank, ensuring you have hot water whenever you need it.

Why Would You Need to Start a Water Heater Pilot?

There are several reasons you might need to start your water heater pilot:

• The pilot light goes out: This is the most common reason. You might notice that your hot water is no longer coming out, or you may see a yellow or flickering flame.
• The water heater is moved or relocated: If your water heater is moved, the pilot light may lose its spark.
• The thermostat is faulty: A faulty thermostat can cause the pilot light to stay off.

How to Start a Water Heater Pilot

Now that we’ve covered the basics, let’s get started!

Step 1: Turn Off the Gas

Before you start, ensure the gas supply is shut off. You should hear a slight hissing noise when you turn the gas valve clockwise. This valve is usually located near the water heater.

Step 2: Allow the Pilot Light to Cooler

Wait for about 10-15 minutes for the pilot light to cool down completely. This step is crucial, as re-lighting the pilot immediately can cause it to sputter or not work properly.

Step 3: Locate the Pilot Light Assembly

Locate the pilot light assembly, which is usually marked with a small diagram showing the pilot light and reset button. You may find it at the bottom, side, or top of the water heater.

Step 4: Press the Reset Button (If Applicable)

Check if your water heater has a reset button! If it does, press it firmly until it clicks. This will restart the pilot light sequence. If your water heater doesn’t have a reset button, proceed to the next step.

Step 5: Light the Pilot Light

Use the pilot light lighter or the long match to spark the pilot light. Place the flame at the opening of the pilot light nozzle and hold it for a few seconds. You might need to adjust the distance and angle to get it to ignite.

Step 6: Monitor the Pilot Light

As the pilot light ignites, you should see it stabilize and maintain a strong, blue flame. Keep an eye on it to ensure it doesn’t falter or go out again.

Step 7: Turn On the Gas

Once the pilot light is stable, turn the gas valve clockwise to restore the gas supply. You should start to hear the main burner ignite, and the tank should begin to heat up.

Step 8: Check the Thermocouple

Ensure the thermocouple (a small metal coil) is not blocked and is not damaged. It’s responsible for maintaining the pilot light flame and ensuring the main burner stays lit. If the thermocouple is faulty, you might need to replace it.

Step 9: Test the Water Heater

Turn on the hot water faucet and check if your water heater is working as expected. If it doesn’t seem to be providing hot water, you may need to adjust the settings or troubleshoot further.

Troubleshooting Common Issues

• Failed to ignite: Check that the pilot light assembly is clean and free of debris. Ensure the pilot light lighter or long match is functioning properly.
• Pilot light keeps going out: Check the thermocouple for blockage or damage. Ensure the pilot light assembly is installed correctly.

Conclusion

Starting a water heater pilot is a relatively simple process, but it requires careful attention to detail. Remember to turn off the gas, allow the pilot to cool, and follow the steps carefully. If you’re still having trouble, consider consulting your water heater’s user manual or calling a professional for assistance.
