So, your water heater's gone out? Don't panic! While it can be frustrating to suddenly have no hot water, relighting a gas water heater is often a straightforward process. This guide will walk you through the steps, focusing on safety and providing clear instructions for common gas water heater types. Remember: If you're uncomfortable performing this task yourself, always call a qualified plumber. Your safety is paramount.
Understanding Your Water Heater Type
Before you begin, identify your water heater type. Most residential water heaters are either gas-powered or electric. This guide focuses solely on gas water heaters. Electric water heaters require a different approach and should be handled by a professional if they malfunction.
There are two main types of gas water heaters:
- Standing Pilot Water Heaters: These have a continuously burning pilot light that ignites the main burner when needed.
- Electronic Ignition Water Heaters: These use an electronic igniter instead of a standing pilot light to start the burner. They are generally more energy-efficient.
Relighting a Gas Water Heater with a Standing Pilot
If your water heater has a continuously burning pilot light, follow these steps:
Step 1: Check the Gas Supply
Ensure the gas supply to your water heater is turned ON. Locate the gas shutoff valve—usually a knob or lever near the water heater—and make sure it's in the "ON" position.
Step 2: Inspect the Pilot Light
Carefully examine the pilot light. Is it out? If so, you'll need to relight it.
Step 3: Turn Off the Gas Supply (Temporarily)
Safety First! Turn the gas supply valve OFF. This is crucial to prevent gas leakage during the relighting process.
Step 4: Locate the Pilot Light and Igniter
You'll find a small hole or opening near the bottom of the water heater, usually with a knob or button controlling the gas flow to the pilot.
Step 5: Hold Down the Igniter Button and Turn On Gas
With one hand, hold down the igniter button (sometimes labeled "ignite" or a similar term). Use a long lighter (at least 12 inches) to carefully light the pilot. Keep the lighter away from the rest of the heater to prevent burns Slowly turn the gas supply valve back ON.
Step 6: Observe the Pilot Light
Keep the igniter button held down for at least 60 seconds after lighting the pilot light to allow the thermocouple to heat up. If the pilot light stays lit after releasing the button, you've successfully relit it!
Step 7: Check for Gas Leaks
After successfully relighting the pilot light, carefully check for any gas leaks by using a soapy water solution. Apply the solution to the gas connections, and watch for any bubbles. If you see bubbles, immediately turn off the gas supply and call a qualified plumber.
Relighting a Gas Water Heater with Electronic Ignition
Electronic ignition systems are usually more automated. However, sometimes they can malfunction, which is why this process may vary. Check the manufacturer's instructions for your specific model. Generally you will see a small button or indicator on your water heater that will start the electronic ignition process.
Step 1: Check the Gas Supply
Ensure that the gas is turned ON to your heater.
Step 2: Reset the System
Many systems have a reset button, typically near the control panel. Press this button if it exists.
Step 3: Attempt to Light the Water Heater.
Follow the manufacturer's instructions provided. Usually, you will need to follow a specific sequence such as turning a dial or pressing a combination of buttons. If the heater doesn't start, there may be an issue with the electronic ignition system, which requires professional attention.
Step 4: Listen for the Igniter
Most electronic ignition systems will produce a clicking sound when attempting to light the burner. If you do not hear this sound, a further inspection of the internal components is required and should be done by a professional.
When to Call a Plumber
While relighting a gas water heater can often be a DIY job, call a qualified plumber immediately if:
- You smell gas.
- You're uncomfortable performing the task.
- The pilot light won't stay lit after multiple attempts.
- The water heater is malfunctioning or leaking.
Ignoring these situations could lead to serious risks. Safety always comes first!
This guide provides general information. Consult your water heater's manual for specific instructions and safety precautions. Remember to prioritize safety and call a professional if you have any doubts.
