How to Flush a Water Heater Tank

Sediment, and sometimes hard water deposits build up in your water heater tank. These deposits will drastically reduce the efficiency of your system. If left unchecked, they will eventually cause malfunction in the system, which may require a new installation. To avoid that problem and prolong the life of your water heater, simply flush the tank every few years. Here are the steps to take:

  • Hook a hose to the drain valve located at the base of the heater tank.
  • Shut off the water supply to the tank. If you have an electric heater, turn off the power to the system.
  • Open a hot water faucet in a bathroom nearby. Open the drain valve and allow the water to run into a safe place where the hot water will not damage property.
  • When the tank is empty, you will need to turn on the water supply to flush any remaining particles out of the tank.
  • Turn the power back on. Turn off the faucet and close the drain valve. Fill the tank.
  • When the tank is full, wait approximately thirty minutes and then test the hot water.
