? Hot Water's Out? Relighting Your Water Heater!

Is your shower turning into an icy ordeal? A pilot light gone out on your water heater is often the culprit. Don't panic! Relighting your water heater is often a simple DIY task. This comprehensive guide will walk you through the process, ensuring you can safely restore hot water to your home. We will explain "how to relight a water heater".

Why is My Water Heater's Pilot Light Out?

Before diving into the "how to relight a water heater" process, it's helpful to understand why your pilot light might have gone out in the first place. Common causes include:

  • Drafts: Strong winds can sometimes blow out the pilot light.
  • Gas Supply Issues: A disruption in your gas supply, even a temporary one, can extinguish the flame.
  • Thermocouple Problems: The thermocouple is a safety device that senses the pilot light and keeps the gas valve open. If it malfunctions, it will shut off the gas.
  • Sediment Buildup: Sediment in the tank can sometimes interfere with the pilot light.

Safety First!

Before attempting to relight your water heater, prioritize safety:

  • Smell Gas? Evacuate! If you smell a strong odor of gas, DO NOT attempt to relight the water heater. Immediately evacuate the premises and call your gas company or 911 from a safe location.
  • Ventilation is Key: Open windows and doors to ensure adequate ventilation.
  • Turn Off the Gas (If Necessary): If you're uncomfortable proceeding, or if the gas smell persists, turn off the gas supply to the water heater. The shut-off valve is usually located on the gas line leading to the unit.

How to Relight a Water Heater: Step-by-Step Guide

Now, let's get to the "how to relight a water heater" process:

  1. Locate the Pilot Light Assembly: This is usually found at the bottom of the water heater, behind a small access panel. Consult your water heater's manual if you're unsure where it is.

  2. Turn the Gas Control Valve to "Pilot": The gas control valve typically has settings for "On," "Off," and "Pilot." Rotate the knob to the "Pilot" position. You may need to push down on the knob while turning it.

  3. Press and Hold the Reset Button: While keeping the gas control valve knob pressed down, press and hold the reset button (often red or black). This button allows gas to flow to the pilot light.

  4. Ignite the Pilot Light: With the reset button held down, use a long-handled lighter or a match to ignite the pilot light. You may need to hold the flame near the pilot light opening for a few seconds. Many newer water heaters have a push-button igniter.

  5. Hold for 30-60 Seconds: Continue holding the reset button down for 30-60 seconds after the pilot light ignites. This allows the thermocouple to heat up and sense the flame. If you release the button too soon, the pilot light will go out.

  6. Release the Reset Button: After 30-60 seconds, carefully release the reset button. The pilot light should remain lit.

  7. Turn the Gas Control Valve to "On": Slowly rotate the gas control valve knob to the "On" position.

  8. Listen for the Burner: You should hear the main burner ignite. If it doesn't, repeat steps 2-7. If it still doesn't ignite, consult a qualified technician.

  9. Replace the Access Panel: Securely replace the access panel.

Troubleshooting: What If It Doesn't Light?

Here's some troubleshooting advice to know "how to relight a water heater":

  • Check the Gas Supply: Make sure the gas is turned on to the water heater. Check other gas appliances in your home to ensure there's gas flow.
  • Clean the Pilot Light Opening: Use a small wire or needle to gently clean any debris from the pilot light opening.
  • Replace the Thermocouple: If the pilot light continues to go out after you release the reset button, the thermocouple may be faulty and need replacing. This is a relatively inexpensive part, but if you're not comfortable replacing it yourself, call a professional.
  • Call a Professional: If you've tried these steps and the water heater still won't light, it's time to call a qualified plumbing or HVAC technician.

Preventing Future Problems

To minimize the chances of your pilot light going out again, consider these preventative measures:

  • Regular Maintenance: Have your water heater inspected and serviced annually by a qualified technician.
  • Protect from Drafts: If drafts are a problem, try to shield the water heater from wind.
  • Flush the Tank: Regularly flush the water heater tank to remove sediment buildup. This will also improve the efficiency of your water heater.
