How To Flush A Water Heater

If your water heater seems to be losing some of its effectiveness, you may think that it is time to replace your unit. However, there is a much less expensive way to restore some of its usefulness. With time, certain minerals begin to build inside the unit. You may be able to eliminate problems and elongate the life of your water heater by performing a simple flushing procedure.

How To Flush Your Water Heater

  1. Turn off the Gas/Electricity - If you have an electric unit, turn off your circuit breaker. Then, disconnect the power supply. If you have a gas unit, place the dial on the "pilot" position.
  2. Stop the Water - The cold water valve that is connected to your water heater should be closed.
  3. Run Hot Water in Your House - Find a nearby faucet that you can run hot water from to prevent a vacuum forming in the lines. As you drain your heater, leave the water running. It will help everything drain faster.
  4. Attach a Hose - While attaching a hose to the drain valve, use protective gloves. Run this hose to a drain or a bucket.
  5. Drain the Tank - At this point, you can open the drain valve so that the water keeps flowing until it stops. During this step, you should use caution. If your heating unit has not adequately cooled, the water may be extremely hot.
  6. Flush the Tank - Open the cold water valve so that sediment can be flushed out. It may be helpful to open and close this valve multiple times.
  7. Close the Drain Valve - After the water stops running, you can disconnect the hose. Tighten and close the drain valve as well.
  8. Fill the Tank - Open the cold water valve. Inside your home, turn on all of your faucets so that air bubbles are not a problem. After the water returns to regular flow, you can turn off all the water faucets.
  9. Turn the Water Heater On - Make sure that your heater tank is filled with water. Then, turn on your electric or gas connections. Be sure to follow the lighting instructions that are found in your manual.

Although there are times when you need a professional plumber, you should be able to flush your water heater on your own. However, if you have questions or concerns regarding your unit, feel free to call EZ Plumbing.
