Locate the spigot on your water heater.
Connect your garden hose to the spigot. Ensure a tight connection to avoid water leaking from the connection between the spigot and the hose.
Lay out and extend your garden hose. You will want to place the end of your hose in an area for the hot water to drain into. Appropriate areas for this drainage is gravel, down your driveway, or into the street gutter.
Pro-Tip: If possible, avoid having the hot water drain into areas with grass, flower beds, or any landscaped vegetation as the hot water may damage your plants, shrubs, flowers, and trees.
Next to the spigot, open the valve to allow water to start flowing out of your water heater. The water will be hot, please exercise caution to avoid injury.
Twist handle counter-clockwise multiple times.
Insert a flat-head screwdriver into the slot and twist counter-clockwise multiple times.
Move the handle into the ‘on’ position, the handle will be aligned in the same direction as the pipe.
To flush your water heater, you will allow water to flow for 5 minutes, followed by 5 minutes of non-flow. This cycle of 5 minutes flowing, 5 minutes non-flowing will be performed 3 times.
After the last cycle of water flowing for 5 minutes, ensure your valve is in the ‘off’ position and remove your hose from the spigot.
