This can happen for various reasons, such as a gas supply interruption or a faulty thermocouple. Whatever the cause may be, we’re here to help you get your pilot light re-lit and your hot water flowing again.

Is It Safe to Relight the Pilot Light Yourself?

Before we dive into the steps of re-lighting the pilot light, let’s address an important question – is it safe for you to do it yourself? While re-lighting the pilot light is generally a simple task, it’s essential to ensure your safety and follow proper precautions. If you’re uncomfortable or unsure about handling gas appliances, it’s best to contact a professional plumber.

However, if you’re confident in your abilities and take the necessary precautions, re-lighting the pilot light can be a straightforward and cost-effective solution. With that in mind, let’s move on to the step-by-step process.

Gathering the Necessary Tools

Before you begin, make sure you have the following tools:

  • Long lighter or fireplace matches
  • Flashlight

Locating the Pilot Light

The next step is to locate the pilot light on your water heater. In most cases, you’ll find it at the bottom of the heater behind a small access panel. Once you’ve located the access panel, carefully remove it, ensuring you don’t damage any components in the process.

Turning Off the Gas

Before attempting to re-light the pilot light, it’s crucial to turn off the gas supply to the water heater. Look for a valve near the bottom of the heater and turn it to the “Off” position. If you smell a strong gas odor or suspect a gas leak, immediately leave the premises and contact your gas company.

Preparing to Re-Light the Pilot Light

With the gas supply turned off, it’s time to prepare for re-lighting the pilot light. Here’s what you need to do:

  1. Wait for at least five minutes to allow any remaining gas to dissipate.
  2. Locate the pilot light assembly, which typically has a red or black button.

Re-Lighting the Pilot Light

Now comes the moment of truth – re-lighting the pilot light. Follow these steps carefully:

  1. Using a flashlight, locate the pilot light burner and the pilot tube.
  2. Press and hold down the red or black button on the pilot light assembly. This helps release gas into the pilot tube.
  3. While holding down the button, carefully light the pilot light burner with a long lighter or fireplace match.
  4. Keep the button depressed for about one minute after the flame has been re-lit. This allows the thermocouple to heat up and signal the gas valve to remain open.
  5. Release the button and check to ensure that the pilot light remains lit. If it goes out, repeat the steps.

Finishing Up

Once the pilot light is lit and stays lit, you can now put everything back together. Follow these final steps:

  1. Turn the gas supply valve back on by rotating it to the “On” position.
  2. Replace the access panel, ensuring it is securely in place.

Remember, if at any point you feel uncomfortable or encounter any issues during the process, it’s best to seek professional assistance.

Re-lighting the pilot light on your water heater is a task that can be done with some basic knowledge and the right precautions. By following the steps outlined in this guide, you should be able to re-light your water heater pilot light safely and efficiently. However, if you’re ever unsure or feel uncomfortable, it’s always wise to contact a professional for assistance. Stay safe and enjoy your hot water!
