Step 2 · Connect Drain Hose
Locate the drain valve at the very bottom of the water heater tank. It will look like a small spigot. Carefully attach one end of a standard garden hose to this valve. Run the other end of the hose to a suitable drainage point, such as a floor drain, a utility sink, or outside to a lawn area that won't be damaged by hot water. Ensure the entire length of the hose is running downhill from the valve to allow gravity to drain the tank effectively. Place a bucket under the valve connection to catch any initial drips when you open it.
