How Do I Relight My Water Heater? A Step-by-Step Guide
So, your water heater has gone out, leaving you with a chilly shower prospect. Don't panic! Relighting a gas water heater is often a straightforward process, but safety is paramount. This guide will walk you through the steps, explaining what to do and what to avoid. Always prioritize safety. If you're uncomfortable performing this task yourself, call a qualified plumber.
Identifying Your Water Heater Type
Before you begin, it's crucial to know what type of water heater you have: gas or electric. This guide focuses on gas water heaters, as electric water heaters don't require relighting. If you have an electric water heater, the problem is likely a tripped breaker or a malfunctioning heating element, requiring a different troubleshooting approach.
Safety First!
- Ventilation: Ensure your water heater area is well-ventilated. Gas water heaters produce combustion byproducts, and proper ventilation prevents carbon monoxide buildup, a deadly gas.
- Gas Leak Detection: Before attempting to relight your water heater, check for gas leaks. Apply soapy water to all gas connections. Bubbles indicate a leak. If you detect a leak, turn off the gas supply immediately and call a qualified gas professional. Do not attempt to relight the water heater if you suspect a leak.
- Turn Off Pilot Light: If the pilot light is still flickering or on, you must turn it off before attempting to relight it. Consult your water heater's manual for specific instructions, as the location and mechanism for turning off the pilot light can vary.
Steps to Relight Your Gas Water Heater
These steps are general guidelines. Always refer to your water heater's specific instruction manual for detailed instructions.
-
Locate the Gas Control Valve: This valve controls the gas flow to the pilot light and burner. It's usually located near the bottom of the water heater.
-
Turn Off the Gas Supply: Locate the main gas shut-off valve for your water heater (usually a valve on the gas line leading to the water heater). Turn it completely clockwise to the "off" position.
-
Turn on the Gas Supply (Partially): Carefully turn the main gas shut-off valve counterclockwise only slightly. You only need enough gas flow to light the pilot light. You don't want the main burner to ignite accidentally!
-
Locate the Pilot Light: The pilot light is typically a small flame near the burner assembly.
-
Press and Hold the Pilot Light Ignition Button: Most gas water heaters have a button you press and hold to allow gas to flow to the pilot light. Consult your water heater's manual for the specific procedure.
-
Light the Pilot Light: While holding down the ignition button, use a long lighter or match to ignite the pilot light. Hold the button down for at least 60 seconds to allow the pilot light to establish itself.
-
Check the Pilot Light: Once you've released the ignition button, carefully observe the pilot light. It should burn steadily with a small, consistent flame.
-
Turn On the Gas Supply Fully: If the pilot light remains lit, slowly turn the main gas shut-off valve fully counterclockwise to its "on" position. Listen for the burner to ignite.
-
Monitor the Water Heater: Observe your water heater for a few minutes to ensure it is operating correctly. Check for unusual noises or smells.
Troubleshooting
- Pilot light won't stay lit: There might be a problem with the thermocouple or gas supply. Contact a qualified plumber.
- Water heater is not heating water: This could be due to several issues beyond a pilot light problem. Check your thermostat settings, the gas supply, or the heating element (if applicable). Professional assistance might be needed.
When to Call a Professional
If you're uncomfortable with any of these steps, or if you encounter any problems, always call a qualified plumber or gas technician. Gas leaks and water heater malfunctions can be dangerous. It's better to be safe than sorry.
This guide provides general information. Always consult your water heater's instruction manual for specific instructions and safety precautions. Remember, safety should be your top priority when working with gas appliances.
