How to Relight Your Water Heater Pilot Light (For Every Major Brand!)

Your hot water heater pilot light holds tremendous power over you. If you’ve ever stepped into your shower on a cold winter morning — with body shivering and teeth chattering — as you wait for hot water that never comes, then you know I speak the truth!

If you own a gas water heater, this can mean one of two things. Either (1) the gas supply has been shut off or (2) your pilot light is out. Let’s first (and quickly) deal with the possibility that your gas supply has been shut off.

1. How to Make Sure Your Gas Supply is On

  1. Find the shut-off valve to your gas line.
  2. You can usually find the shut-off valve close to your gas meter (see illustration below), which is located on the side or front of your home or main building.
  3. Make sure the shut-off valve connected to your gas line is in the “ON” position.
  4. If it is not in the ON position, then the problem is not with your gas line.
  5. If it is in the OFF position, turn the valve to the ON position. Feel free to call your local gas company for advice.

The first step in diagnosing the lack of hot water is to check your gas line. Make sure the gas shut-off valve is in the ON position.

If all is okay with your gas supply, then it’s time to check out your water heater pilot light.

2. How to Light Your Pilot Light Water Heater

The process of relighting a pilot light is different for each manufacturer. Fortunately, there are only a few manufacturers. Your first step should be to look for the instructions usually glued onto your water heater. Don’t worry if you can’t find them. We have specific brand-by-brand instructions written below.

This video contains “generalized” instructions. For instructions specific to your brand of water heater, scroll below.

A Rheem water heater pilot light needs to be lit manually using the piezo ignitor striker built into the water heater.

  1. Rotate the gas knob on your Rheem water heater clockwise until it is in position.

  4. Rotate the gas knob counter-clockwise until it is in the “Pilot Light” position.
