How to Light the Pilot on a Hot Water Tank: A Step-by-Step Guide
In this article, we’ll walk you through the simple process of lighting the pilot on a hot water tank. Whether you’re dealing with a malfunctioning heating system or a freshly installed water heater, following the right steps can help ensure a safe and successful experience.

Why Light the Pilot?
Before we dive into the process, let’s clarify the importance of lighting the pilot on a hot water tank. When your water heater is in continuous operation, the pilot (a small flame that runs continuously) keeps the heater running smoothly. When you turn off the pilot, the heater enters an offline mode, and when it’s turned back on, the pilot needs to be relit to start generating hot water again. Lightening the pilot helps you:
• Restart your heating system
• Extend the lifespan of your water heater
• Reduce the risk of damage to surrounding areas
The Light Pilot Process: Step-by-Step
Now, let’s get started! Lightening the pilot requires the following steps:
• Step 1: Ensure the power is shut off
Make sure you have turned off the circuit breaker or main fuse at the electrical panel controlling your water heater.
• Step 2: Verify the pilot light access
Check your water heater for a pilot light access port or window. Ensure it’s clear and clean of debris or obstacles to facilitate the lighting process.
• Step 3: Release pressure in the tank
Using your water heater’s release handle, vent pressure relief valves to ensure your water heater is free from high pressure. (Most modern water heaters come with automatic pressure relief valves.) Check your specific user manual for specific release handles and procedures.
• Step 4: Remove any caps or shutters
Disconnect and remove any pilot caps, shutters, or limiters that cover or obstruct the pilot or flame sensor. This exposes the pilot light assembly to natural light.
• Step 5: Spark ignition
Hold a 10-15 cm pilot light igniter probe close to the pilot assembly, about 3/4 inch (19 cm) from the sensor hole. Turn on the igniter until it produces a spark.
Additional Tips for a Successful Lighting Experience:
Beware of the following key factors to ensure a hassle-free pilot lighting experience:
• Humidity: High humidity in your environment can cause water in the pilot line to collect, making it challenging to light the pilot.
• Clogged ports or tubes: Inspect for any blockages, like lint or debris, clogging the pilot light access port or tubes. Clear the area before attempting to relight the pilot.
• Incorrect lighting distances or angles: Adjust your hold and angle on the probe to ensure proper clearance around the pilot light.
Table: Troubleshooting Common Issues
| Symptoms | Causes | Solutions |
|---|---|---|
| Pilot light does not light | Faulty or worn-out pilot ignition switch | Replace the pilot igniter or switch. Ensure proper installation. |
| Pilot light flickers | Dirty or corroded spark electrodes | Clean and clean spark electrodes or replace spark electrodes. |
| Water heater won’t restart after relighting pilot | High internal pressure | Release excess water pressure or contact a professional for assistance. |
Conclusion
By following these simple steps and important tips, you can relight your hot water tank’s pilot and resume safe and efficient hot water heating. Remember to:
- • Check for debris or obstructions along the pilot light assembly.
• Practice basic safety precautions, including shut-off of the electrical supply and pressure release during lighting procedures.
Contact a professional if you experience ongoing issues or if the hot water tank requires routine maintenance or replacement.
