How to Check the Pilot Light on a Water Heater
As a homeowner, it’s essential to know how to maintain and troubleshoot your water heater to ensure it’s working efficiently and safely. One critical aspect of water heater maintenance is checking the pilot light, which is responsible for igniting the burner that heats the water. In this article, we’ll provide a step-by-step guide on how to check the pilot light on a water heater.
Why is the Pilot Light Important?
Before we dive into the steps, it’s essential to understand the significance of the pilot light. The pilot light is a small flame that ignites the burner, which heats the water in the tank. If the pilot light goes out, the water heater will not work, and you’ll be left with no hot water. A faulty pilot light can also lead to potential safety hazards, such as carbon monoxide poisoning and water damage.
The Importance of Regular Checks
Regularly checking the pilot light is crucial to ensure the water heater is functioning properly. Here are some signs that the pilot light might be malfunctioning:
• No hot water: If you’re not getting any hot water, it’s likely the pilot light has gone out.
• Unusual noises: Listen for unusual noises, such as clicking, hissing, or rattling, which could indicate a pilot light issue.
• Water leaks: A malfunctioning pilot light can cause water to leak from the tank.
Step-by-Step Guide to Checking the Pilot Light
Before you start, make sure you’re wearing gloves and safety glasses to protect yourself from any potential hazards. Here’s a step-by-step guide to checking the pilot light:
**Step 1: Locate the Pilot Light**
- The pilot light is usually located at the bottom of the water heater or on the side. Look for a small glass cover or a metal grille with a hole in the center.
- If you have a gas water heater, the pilot light is typically located near the burner.
Step 2: Identify the Pilot Light Type
- There are two main types of pilot lights:
- Standing Pilot: A standing pilot light is always burning, usually at a low flame, and is typically used on older water heaters.
- Intermittent Pilot: An intermittent pilot light only burns for a short period when the water heater is in operation.
Step 3: Check the Pilot Light
- Standing Pilot: For standing pilot lights, look for a flame burning through the glass cover or metal grille. Check for a strong, steady flame.
- Intermittent Pilot: For intermittent pilot lights, look for a short, brief flame when the water heater is in operation.
What to Do if the Pilot Light is Out
- Do not try to relight the pilot light without ensuring the surrounding area is clear of any ignition sources.
- Make sure the water heater is turned off at the gas supply valve to prevent any accidents.
- Check for any blockages in the pilot light tube or burner assembly. Clean or replace them if necessary.
Table: Common Causes of Pilot Light Issues
| Cause | Solution |
|---|---|
| Clogged pilot light tube | Clean or replace the pilot light tube |
| Faulty thermocouple | Replace the thermocouple |
| Dirty or clogged burner | Clean or replace the burner |
| Ignition issue | Adjust the ignition knob or replace the ignition assembly |
Tips and Precautions
- Always turn off the gas supply valve before attempting to relight the pilot light.
- Keep the area around the pilot light clean to prevent any ignition hazards.
- Never use a match or lighter to relight the pilot light as it can cause accidents.
- If you’re not comfortable with this process, consider hiring a professional plumber to check the pilot light for you.
