Flushing a Tank-Styled Water Heater

Even though a tank-styled water heater doesn’t need a mandatory cleaning every year (like a tankless water heater or boiler), there are still ways you can help keep a tank-styled water heater maintained. This cleaning guide can be used on tank-styled water heater brands such as AO Smith, Bradford White, and Rheem!

Sediment buildup in a tank-styled water heater can reduce your water heater’s energy efficiency and clog your water lines. To help alleviate these problems, and to help increase the life of the water heater, flush the tank every time you check the pressure relief valve.

Step 1
Turn off the electricity to the water heater, or turn off the gas to extinguish the pilot light.

Step 2
Connect a garden hose to the tank’s drain valve. Locate the draining end of the hose in an area that won’t be adversely affected by the scalding hot water. Gradually open the drain valve, and run for 30 seconds to 1 minute.

Step 3
Close the tank drain valve, and disconnect the hose from the valve. Open each hot water spigot until all air is removed from the system.

Step 4
Close each hot water spigot as water begins to flow from it. After all the spigots are closed, turn on the electricity to the water heater, or re-light the pilot light and reset the gas valve to the previous temperature setting.
