Maintaining Your Water Heater by Flushing Sediment Annually


Maintaining Your Water Heater by Flushing Sediment Annually
It doesn’t always take a technician to improve your water heater’s performance and efficiency (although it doesn’t hurt to have one check it on a regular basis). One of the things you can do on your own is flush your water heater of sediment and debris that has accumulated along the bottom of the tank.

It’s a relatively simple process that only requires following a few simple instructions:

  • Make sure the power to the unit is turned off. For electric units, simply switch the unit off at the circuit breaker. For gas units, switch the burner to “pilot” mode.
  • Locate and open the pressure relief valve. Attach a garden hose to the drain valve near the bottom of the unit. Run the other end of the hose to a nearby drain or outdoor drainage area. Don’t forget to give the unit enough time for the water inside the tank to cool down.
  • Open all of the hot water faucets in your home, and then open the drain valve. Allow the water in the tank to drain completely.
  • Periodically open the cold water supply valve on the unit in short bursts. This will help dislodge stubborn sediment buildup.
  • Once the water coming out of the tank appears clear, close the drain valve, remove the hose and open the supply valve to refill the tank. Make sure the pressure relief valve is closed before turning the water heater back on.

If necessary, you can also remove the drain valve and manually scrape the bottom of the tank to dislodge stubborn sediment buildup. Of course, you should make sure the tank is completely drained before you do this.
