How to Check and Relight the Pilot Light on Your Water Heater
If you’ve suddenly lost hot water in your home, the pilot light on your water heater might be the culprit. At PR Plumbing, Heating, and Air Conditioning in Fresno, we want to help you restore hot water safely and easily. Here’s how to check your pilot light and relight it if needed.
1. Confirm There’s No Hot Water
Start by running a hot water tap. If no hot water is coming out, your water heater might not be operating correctly.
2. Locate the Sight Glass
At the bottom of your water heater, you’ll find a small sight glass or viewing window. Look through it to see if the pilot light is on. If it’s dark or you don’t see a flame, the pilot light is likely out.
3. Follow the Manufacturer’s Lighting Instructions
Every water heater is a little different, so check the label or sticker on the side of the unit for specific lighting instructions. Most involve turning the control knob to 'pilot,' pressing it down, and using the igniter button or a match to light the flame.
4. Wait and Test
Once relit, give your water heater some time to warm up—usually 30 to 60 minutes. Then, check the temperature at a nearby fixture to confirm it’s heating properly.
