How to Tell If Pilot Light is On Water Heater?
Contents
A Brief Introduction
The pilot light is a crucial component of a water heater’s burner system, responsible for igniting the main burner when you turn on the water heater. A functioning pilot light ensures a safe and efficient water heating process. However, it’s not uncommon for homeowners to worry about the pilot light being on or off. This article will guide you on how to determine if your water heater’s pilot light is on or not.
Common Methods to Check the Pilot Light
To check if the pilot light is on, follow these steps:
- Listen for the Click: Before you start, ensure your water heater is off and the pilot light assembly is cool to the touch. Listen carefully for the gentle clicking sound of the pilot light igniting. If you don’t hear the click, it could indicate that the pilot light is not on.
- Check the Igniter: Locate the igniter button or probe attached to the pilot light. Press the igniter button or gently turn the igniter probe back and forth to activate it. A faint hiss or sizzling sound will usually occur when the pilot light is on.
- Check the Flame: Shine a flashlight or flashlight-like device through the pilot light opening to observe the flame. If you see a small, blue-flame, it indicates that the pilot light is lit and functioning correctly. Avoid touching the flame as it may be hot.
- Check the Burner: Visually inspect the burner assembly for any signs of a flame. Look for a yellowish or blueish hue emanating from the burner orifices, indicating a pilot light is on.
- Check the Control Valve: If you’re unsure, check the control valve that regulates water flow to the water heater. A slight increase in pressure or a steady hissing sound indicates that the pilot light is on and the water heater is functioning.
Risks Associated with an Unlit Pilot Light
Failure to maintain a lit pilot light can lead to severe consequences, including:
• Water Heater Failure: A non-functioning pilot light can prevent the water heater from producing hot water, leaving you without this essential household necessity.
• Leaks and Damage: When the pilot light is out, water can seep into the burner chamber and surrounding areas, potentially causing damage, rust, and corrosion.
• Risk of Fire: An unlit pilot light can accumulate gases, such as propane, which can ignite if they reach the main burner or other combustible materials. This can lead to fires and potential explosions.
• Energy Inefficiencies: A non-lit pilot light can increase your energy bills as the water heater struggles to function inefficiently.
Safety Precautions to Take
To ensure your water heater’s pilot light is working safely and efficiently, follow these guidelines:
• Regular Maintenance: Regularly inspect and clean your water heater’s burner area, including the pilot light assembly, to prevent build-up and ensure proper ignition.
• Annual Check-Ups: Hire a professional to inspect and service your water heater annually, or more frequently if you use your water heater heavily.
• Proper Ignition: Ensure proper pilot light ignition by not jarring or disturbing the water heater while it’s still warm.
• GFCI Protection: Ensure your water heater has a Ground Fault Circuit Interrupter (GFCI) outlet, which provides electrical shock protection.
Conclusion
In conclusion, checking the pilot light on your water heater is a relatively straightforward process. By following the steps outlined above and staying informed about the potential risks and safety precautions, you’ll be better equipped to maintain your water heater and enjoy consistent, safe, and efficient hot water supply.
