Flushing Your Water Heater

water heater maintenance

To flush your water heater, you will need to follow these steps:

  1. Turn off the power to the water heater. If your water heater is electric, you will need to switch off the circuit breaker or unplug it. If it is gas-powered, you will need to turn off the gas supply at the gas valve.
  2. Attach a hose to the drain valve at the bottom of the water heater. This valve is typically located on the side of the tank, and it is used for draining and flushing the tank.
  3. Place the other end of the hose in a floor drain or outside where the water can drain safely.
  4. Open the drain valve by turning the handle counterclockwise. Water and sediment will begin to flow out of the tank and through the hose.
  5. Allow the water to flow until it runs clear. This may take a few minutes or longer, depending on the amount of sediment in the tank.
  6. Close the drain valve by turning the handle clockwise.
  7. Turn the power back on to the water heater and refill the tank by opening the cold-water supply valve.
  8. Once the tank is full, turn on the hot water faucet nearest to the water heater to allow air to escape from the tank.
  9. Check for any leaks and make sure the drain valve is tightened securely.


It is recommended to flush your water heater at least once a year to remove sediment and improve the efficiency of the appliance. It is also recommended to have it serviced to maintain the warranty based on the manufacturer’s request. If you decide you would like professional help, you can contact us to book an appointment.
