How to Flush a Water Heater
- Turn the power source of your water heater off – many water heaters are fueled by gas but some are electric. Ensure that either the gas is shut off to the heater or the electricity is turned off at the breaker before beginning any DIY task for your water heater.
- Turn off the cold water supply – once your water heater has been turned off, stop the flow of water to the tank by turning off the water supply. This will often look like a blue knob with an appearance similar to that of an exterior water hose line.
- Turn on a sink with hot water – turn on the hot water on a nearby tub or sink. Keep it on through the flushing process to prevent a vacuum that stops the tank from draining.
- Connect a hose to the drain spigot – keep in mind where you want to drain the water into when you connect the hose and be prepared. Some homeowners drain the tank into a bucket while others utilize the floor drain in their home. Consider your surroundings when choosing a draining option that works for you.
- Drain the tank – drain the tank until you no longer see sediment. You may need to drain only a small amount of water or may need to drain the entire tank if your tank has a lot of sediment in it.
- Flush the tank – to flush the water tank, turn the cold water supply back on and let it flush through the water tank until the water runs clear from the drainage hose. Once clear, turn off the cold water once more.
- Disconnect the hose and refill the tank – once you have flushed your tank, disconnect the hose, turn off the hot water in your tub or faucet, and turn the cold water back on. Don’t forget to turn another hot water faucet on while the tank refills to ensure air stays out of the system, then turn it off again.
- Turn on the power source – once you have completed these steps it is time to turn the power source back on. The water in your tank will be cold, give it time to reheat before attempting to draw warm water from a faucet.
