Learning how to relight a gas water heater is a valuable skill that can save you time and money. Whether you have a newer model with automatic ignition or an older one that requires manual relighting, these steps will guide you through the process.

Prepping to Relight Your Water Heater

Before attempting to relight your gas water heater, it’s crucial to prioritize safety. Gas appliances can be dangerous if not handled properly, so follow these steps to ensure a safe relighting process:

Shut off the gas valve on your water heater and wait for any residual gas to dissipate.
Use a flashlight to locate the pilot light, which is typically positioned under the gas valve.
If your water heater has a separate pilot button, press it to initiate the gas flow. Otherwise, you’ll need to light the pilot manually using a long lighter.

Steps to Relight Your Gas Water Heater

Once you’ve taken the necessary safety precautions, you can proceed with relighting your gas water heater following these steps:

Turn the gas valve to the “Pilot” position and hold it down to allow gas to flow.
Use a lighter to ignite the pilot light, keeping the gas knob or button depressed for about a minute.
After ensuring the pilot light is lit, turn the gas valve back to the “On” position and replace any covers or doors.
