Draining a water heater is a crucial maintenance task that ensures its optimal performance and longevity. However, the presence of a pilot light can raise concerns about safety and potential hazards. This comprehensive guide will provide a step-by-step process to safely drain your water heater, addressing the question of whether it can be done with the pilot light on.
Understanding the Pilot Light
A pilot light is a small flame that continuously burns inside a water heater. It ignites the main burner when hot water is required. Turning off the pilot light means interrupting the ignition process and preventing the water heater from producing hot water.
Safety Considerations
Can you drain water heater with pilot on? The answer is a resounding **NO**. Draining a water heater with the pilot light on can be extremely dangerous and lead to severe injuries or even explosions.
Here’s why:
- Gas buildup: When the water heater is drained, gas can accumulate in the tank and lines. If the pilot light is still burning, it can ignite this gas, causing an explosion.
- Scalding: Hot water can escape from the drain valve, posing a severe scalding hazard.
- Carbon monoxide poisoning: If the pilot light is not properly extinguished before draining, carbon monoxide can leak into the surrounding area, creating a health risk.
Step-by-Step Draining Process
1. Shut Off Gas Supply:
- Locate the gas control valve near the bottom of the water heater.
- Turn the valve clockwise to shut off the gas supply.
2. Extinguish Pilot Light:
- If the pilot light is still burning, carefully follow the manufacturer’s instructions to extinguish it.
- Never use water to extinguish the pilot light; this can cause damage.
3. Attach Drain Hose:
- Connect a garden hose to the drain valve at the bottom of the water heater.
- Direct the other end of the hose to a suitable drainage area.
4. Open Drain Valve:
- Slowly open the drain valve by turning it counterclockwise.
- Allow the water to drain completely.
5. Close Drain Valve and Gas Supply:
- Once all the water has drained, close the drain valve tightly.
- Turn the gas control valve counterclockwise to turn the gas supply back on.
6. Relight Pilot Light:
- Follow the manufacturer’s instructions to relight the pilot light.
- Ensure the pilot light is burning steadily before using the water heater.
Troubleshooting Common Issues
Water not draining:
- Check if the drain valve is fully open.
- Inspect the drain hose for any kinks or blockages.
Gas smell after draining:
- Make sure the gas control valve is turned off tightly.
- If the smell persists, contact a qualified plumber immediately.
Additional Tips
- Drain your water heater every 6-12 months to remove sediment and improve efficiency.
- Flush the tank thoroughly after draining to remove any remaining sediment.
- If you are uncomfortable performing this task yourself, contact a licensed plumber.
