Heater Noise If you hear your water heater gurgle, pop or snap, it’s time to drain out sediment. Flushing 3 to 4 gal. prolongs the life of the heater.
How to Drain a Water Heater
- Begin by turning off the power or gas to the water heater.
- Next, turn the cold water supply valve off that allows water to flow into the heater.
- Hook a garden hose to the drain valve at the bottom of the tank and run it outside on the ground.
- Open the drain valve where the hose is attached.
