How to Flush Your Water Heater

Why Flush

Sediment builds up on the bottom of the tank, reducing efficiency and capacity. Annual flushing extends the heater's life by 3-5 years.

Steps

1. Turn off the gas or breaker to the water heater
2. Connect a garden hose to the drain valve at the bottom
3. Run the hose outside or to a floor drain
4. Open the drain valve and let water flow until it runs clear (3-5 minutes)
5. Close the valve, disconnect the hose
6. Turn the gas/breaker back on

When to Do It

Once a year. If you hear popping or rumbling from the tank, flush it immediately — that's sediment boiling.
