Water Heater Pilot Light Out? What Metro Vancouver Homeowners Should Know
A gas water heater with a pilot light that has gone out is one of the most common service calls BC Wide receives, especially during the fall and winter months when the units are working hardest. While relighting a pilot light is a relatively simple procedure, it is important to understand why it went out and whether the underlying issue has been resolved. In Metro Vancouver, homes in Burnaby, Vancouver, Surrey, and surrounding areas often have gas water heaters with standing pilot lights that can be affected by drafts, component wear, or gas supply interruptions. This guide walks you through the safe relighting procedure and explains when a simple fix is sufficient versus when professional service is needed to address a recurring problem.
How to Safely Relight Your Water Heater Pilot Light
Before attempting to relight your water heater pilot, locate the gas control valve on the front of the unit. Turn the valve to the off position and wait a full five minutes for any accumulated gas to dissipate. This waiting period is essential for safety. After five minutes, turn the valve to the pilot setting. Depress and hold the reset button while using a long-reach lighter or BBQ igniter to light the pilot flame through the access opening. Continue holding the reset button for about thirty seconds after the pilot ignites to allow the thermocouple to heat up and signal the gas valve to stay open. Release the button, verify that the pilot flame remains lit, and turn the valve to the on position.
Common Reasons Why Pilot Lights Keep Going Out
If your water heater pilot light keeps going out after you relight it, there is likely an underlying issue that needs professional attention. The most common cause is a faulty thermocouple, a safety device that senses whether the pilot flame is present and shuts off gas if it does not detect sufficient heat. A weak or dirty thermocouple may not generate enough electrical current to keep the gas valve open. Drafts from open windows, doors, or ventilation fans can blow out the pilot flame, especially in basements or mechanical rooms. A dirty pilot orifice can produce a weak, yellow flame that fails to properly heat the thermocouple. In some cases, the gas control valve itself may be failing and requires replacement.
When to Call a Professional for Pilot Light Problems
If the pilot light will not stay lit after three relight attempts, or if you smell gas at any point during the process, stop and call a licensed gas fitter immediately. A strong gas odor indicates that the safety system may not be functioning properly, and continuing to attempt relighting could be dangerous. If your pilot flame is yellow or orange instead of blue, this indicates incomplete combustion and the burner assembly may need cleaning or adjustment. BC Wide's licensed technicians carry replacement thermocouples, gas control valves, and burner assemblies for most water heater brands. We serve all of Metro Vancouver, including Burnaby, Vancouver, Surrey, Coquitlam, Richmond, Delta, Langley, and the North Shore. Call (604) 330-3953 for prompt service.
Safety Reminder
If you smell gas, suspect carbon monoxide or believe there is an immediate danger, leave the property and contact emergency services or the appropriate gas emergency authority. Do not remain inside — exit the building immediately and call for help from outside.
